| 13:48.15 | GuySoft | hey all, i have a wifi phone that runs on OMAP1710. is there a way to flash it from linux? |
| 13:49.12 | RobotGuy | We'd need more info. I can't help with this, but others here could tell you better. |
| 13:49.37 | RobotGuy | What model and manufacturer of phone is it? |
| 13:51.53 | GuySoft | RobotGuy, its the SMC WSKP100: http://elinux.org/SMC_WSKP100 |
| 14:25.40 | RobotGuy | Do you mean flash it from the phone's Linux, while the phone is running? I would not think that would be possible. You would have to flash it from an external source. |
| 14:27.02 | RobotGuy | Flashing replaces the firmware on the phone. |
| 14:58.08 | solar | often for initial porting of cells that are/were CE/WM based it's done first via haret.exe |
| 15:00.51 | GuySoft | RobotGuy, i know.. there is no rewritable flash there. so any kind of modification will have to be by flashing it |
| 15:53.30 | *** join/#edev Ei5GTB_ (n=Paul@78.16.103.96) |
| 16:01.59 | RobotGuy | What did you mean by flashing from Linux? |
| 16:03.31 | RobotGuy | If there is no rewirtable flash, how are you going to flash it? |

| 16:28.51 | GuySoft | Redhatter, i am running my PC on linux, i want to flash from it |
| 16:30.47 | solar | did not know Redhatter idled here.. Perhaps we can get an embedded-mips team going.. |
| 16:36.58 | RobotGuy | GuySoft: OK, that's better. If you have access to the JTAG on your WiFi phone, you should be able to flash it (if it has flash memory). |
| 16:37.22 | RobotGuy | solar: Good morning. I am "making it" now. :) Or at least trying to. |
| 16:37.24 | GuySoft | Jtag? |
| 16:37.40 | GuySoft | RobotGuy, whats jtag/ |
| 16:38.10 | GuySoft | RobotGuy, i notice that when i connect the phone when its off, it is detected as a usb device |
| 16:38.24 | RobotGuy | GuySoft: Why do you want to reflash your WiFi phone?? |
| 16:39.21 | GuySoft | RobotGuy, well, i wanted to play around and see if i can add to it extra functionality.. i use linux on a daily basis.. i taught that i might tweak it like i tweak anything else |
| 16:40.01 | RobotGuy | GuySoft: You need to learn some basic things, like what JTAG is and how it is used before you can do that. |
| 16:40.32 | GuySoft | Redhatter, well, i guess ill start with FAQs - like what is jtag? |
| 16:40.44 | GuySoft | is it a way to talk to the hardware? |
| 16:41.04 | RobotGuy | GuySoft: Tweaking an embedded device like your WiFi phone is not the same as changing something on your Linux desktop PC. |
| 16:41.35 | RobotGuy | GuySoft: JTAG is how you reflash devices like your WiFi phone. |
| 16:41.54 | RobotGuy | Google for JTAG and you should get a good link that explains it. |
| 16:44.16 | GuySoft | there seems to be a debian package |
| 16:45.08 | RobotGuy | GuySoft: A debian package for what? |
| 16:45.36 | RobotGuy | You need a JTAG programmer before you would be able to reflash your WiFi phone. |
| 16:46.19 | RobotGuy | You can not just change things on your phone the same way you change things on your Linux PC. |
| 16:46.26 | RobotGuy | It does not work the same way. |
| 16:46.27 | GuySoft | Redhatter, but there is a windows utility that lets you reflash the firmware without any programmer |
| 16:47.06 | RobotGuy | GuySoft: What utility is that? |
| 16:48.00 | RobotGuy | There is always a programmer of some sort required, whether it is on the device or the host PC. |
| 16:49.12 | RobotGuy | The device is your WiFi phone. |
| 16:49.22 | GuySoft | RobotGuy, http://spritesmods.com/?art=wskpsip&page=3 . basic they moded the firmware upgrade for windows. but since this seemed generic to me, i was hoping there is a linux tool for this |
| 16:49.28 | GuySoft | RobotGuy, yes |
| 16:53.24 | solar | RobotGuy: awsome.. Now just stay in that good mood and build stuff :) |
| 16:55.14 | RobotGuy | solar: I am creating an ArduinoBot. :) |
| 16:55.49 | RobotGuy | GuySoft: That is something completely different from reflashing your WiFi phone. It does not apply in your case.\ |
| 16:57.01 | RobotGuy | solar: I already have my SSC-32 and Arduino with Proto Shield mounted inside a CD media case (what the media comes in when you buy it). |
| 16:57.12 | GuySoft | RobotGuy, why not? its loads diffrent linux system on to the device.. thats all i need |
| 16:57.24 | GuySoft | a different* |
| 16:57.57 | RobotGuy | GuySoft: What you are looking at will not reflash your WiFi phone. Did you start out by reading the intro page? |
| 16:59.36 | GuySoft | RobotGuy, i did.. i understand he did play with alot of hardware.. but the final tool he hands out works without any disassembling the phone |
| 16:59.44 | GuySoft | RobotGuy, and it does write to the chip.. |
| 17:00.07 | RobotGuy | GuySoft: OK, then, I am not able to help you any further, sorry. |
| 17:00.35 | GuySoft | RobotGuy, i am sorry, did i say something worng? |
| 17:01.51 | RobotGuy | GuySoft: I am just not able to help you with using that software or whatever it is. I do not think it will let you do what you want to do. |
| 17:03.58 | GuySoft | RobotGuy, oh well, thanks anyway.. ill see if i can tap in to the phone another way |

| 18:05.24 | RobotGuy | Sometimes I'm the bug and sometimes I'm the windshield. Today I think I am the bug.. |
| 18:05.43 | g1powermac | oh man |
| 18:05.54 | g1powermac | should've read that conversation |
| 18:06.19 | RobotGuy | g1powermac: The one with GuySoft? |
| 18:06.26 | g1powermac | yea |
| 18:06.42 | RobotGuy | I really tried to help him. |
| 18:06.43 | g1powermac | I still have that phone sitting here doing nothing |
| 18:07.10 | RobotGuy | Oh wow. |
| 18:07.32 | g1powermac | really should send it off to prpplague for a little special hacking to find its jtag and serial port if he's willing :-) |
| 18:07.56 | RobotGuy | I tried to tell GuySoft he was on the wrong track. |
| 18:08.24 | RobotGuy | Maybe I am the one who was wrong there. |
| 18:09.00 | prpplague | will re-read the log later |
| 18:09.22 | g1powermac | yea, me too |
| 18:09.50 | RobotGuy | He didn't even know what JTAG is and what it's used for. |
| 18:10.02 | g1powermac | ahh |
| 18:10.04 | prpplague | RobotGuy that isn't surprising |
| 18:10.17 | prpplague | RobotGuy most people haven't ever heard of jtag |
| 18:10.38 | RobotGuy | I tried to explain to him that changing his phone software was not the same as changing software on his Linux PC. |
| 18:11.24 | g1powermac | ok, well, he was a bit too new at embedded linux to really help with hacking that phone |
| 18:11.40 | g1powermac | which is good really, I must not get another project going. . . |
| 18:12.18 | RobotGuy | g1powermac: I know that, and I tried to explain to him that he needed to learn some basics before trying to jump into something like changing his phone software. |
| 18:12.41 | g1powermac | really doesn't like having so many projects going at the same time |
| 18:12.56 | g1powermac | got at least four of them going |
| 18:13.04 | RobotGuy | I just have two projects now, W.A.L.T.E.R. and the new robot. |
| 18:13.19 | g1powermac | one that doesn't even relate to electronics |
| 18:13.42 | RobotGuy | I just can't get the power connected to Arduino. Otherwise, I am ready to start testing the hardware and such. |
| 18:13.43 | g1powermac | one 8051 project, and two linux projects |
| 18:14.34 | g1powermac | and all but the zipit project needs more parts to finish them |
| 18:14.45 | RobotGuy | I'm going to run everything off a 6V @ 1600 mAH NiMH battery pack. |
| 18:15.19 | prpplague | likes to finish a project before moving on to another one |
| 18:15.20 | RobotGuy | I am missing a right angle male barrel connector for power to the Arduino. :( |
| 18:15.35 | RobotGuy | I need something I can work on at all times. |
| 18:15.57 | g1powermac | prpplague, thats what I usually like to do, or at least completely forget about the other projects while working on one single one |
| 18:16.11 | g1powermac | right now, I can't seem to focus just on one |
| 18:17.11 | prpplague | g1powermac i have about 20 i'd like to do, but with this m8050 going on, i can't spare the brain clocks |
| 18:17.15 | RobotGuy | I'm sort of stalled on W.A.L.T.E.R. right now, so need something else I can work on. |
| 18:17.20 | g1powermac | prpplague, yea |
| 18:17.30 | prpplague | RobotGuy what is stalled? |
| 18:17.49 | prpplague | roxfan seems like there would a ton of work to do and test |
| 18:17.53 | RobotGuy | prpplague: Software dev for W.A.L.T.E.R. |
| 18:18.03 | g1powermac | prpplague, one interesting thing I found is this: http://emile.sourceforge.net/index.php |
| 18:18.15 | g1powermac | prpplague, an actual real linux bootloader for old m68k macs |
| 18:18.32 | g1powermac | no hijacking mac os to load linux |
| 18:18.59 | roxfan | uh what? |
| 18:19.10 | g1powermac | I'm planning to help out the developer with coding for it |
| 18:19.13 | prpplague | RobotGuy what aspect of the software are you stalled on? |
| 18:19.25 | prpplague | g1powermac cute |
| 18:19.43 | RobotGuy | prpplague: Everything. I don't have a working software dev env. |
| 18:19.49 | g1powermac | wants to delve into the Mac ROM and see how I can improve the bootloader |
| 18:21.08 | prpplague | RobotGuy again? |
| 18:21.14 | prpplague | RobotGuy what the hell happened? |
| 18:21.34 | RobotGuy | prpplague: Still. Main PC is not working right. That's where all my stuff is. |

| 18:38.28 | prpplague | solar however, we got a nastygram from parallax over that |
| 18:38.46 | prpplague | solar so i i'm not sure, but i'd suspect they are going to have to change their name |
| 18:38.50 | solar | I bet. the avr's are the basicstamp killers |
| 18:39.36 | prpplague | main i wish that mag was available around here |
| 18:39.39 | prpplague | checks |

| 18:49.02 | chouimat | ok brb need to go buy a power supply 3 to 12V |
| 18:49.22 | chouimat | RobotGuy: it worth the price |
| 18:49.29 | RobotGuy | It's also a large format magazine - larger than our magaizines. |
| 18:49.41 | RobotGuy | chouimat: I agree completely. |
| 18:50.05 | prpplague | oh well, i'll just have to wait |
| 18:50.09 | RobotGuy | It's almost USA newspaper size |
| 18:53.46 | prpplague | yea i can't find it anywhere, called 10+ places |
| 18:54.13 | prpplague | surprised though, i would have thought he'd give me an email or something letting me know |
| 18:55.40 | RobotGuy | prpplague: Do you have Barns & Noble and/or Borders there? |
| 18:56.32 | prpplague | RobotGuy yea, called all three, they don't carry it |
| 18:56.59 | RobotGuy | prpplague: Wow. They usually carry it here. |
| 18:57.07 | prpplague | RobotGuy yea you live in a tech area |

| 19:13.15 | RobotGuy | Might go do that today. I am starting to go stir crazy here and need to get out for a bit. |
| 19:14.30 | RobotGuy | I need to get some heat shrink and a couple right angle barrel connectors too, but Norvac isn't open on weekends anymore. :( |

| 21:17.36 | prpplague | solar ping |
| 21:19.48 | solar | prpplague: funny I was just coming here to ping you |
| 21:19.56 | solar | prpplague: ping |
| 21:19.59 | solar | prpplague; pong |
| 21:20.56 | prpplague | solar HA |
| 21:21.00 | prpplague | solar you first then |
| 21:21.33 | solar | this should be a basic question for you. |
| 21:21.41 | prpplague | oh lord |
| 21:22.11 | solar | A transistor can be used as a basic switch. Ie I can use it to flip the voltage of a motor from +|- to -|+ to control direction? |
| 21:23.50 | prpplague | solar yes you can use transistors to do that, however, it becomes a little more complicated when you need to switch two lines in two directions |
| 21:24.14 | prpplague | solar http://en.wikipedia.org/wiki/H-bridge |
| 21:25.25 | prpplague | solar http://www.sparkfun.com/commerce/product_info.php?products_id=315 |
| 21:25.39 | solar | ok. here is my Sat idea. I've ripped apart an old CD housing. It's a good little size to fit the arduino,nail,my solar panels and the battery. It's got a flat bottom so attaching a few motors as wheels might be fun |
| 21:26.10 | prpplague | solar http://www.sparkfun.com/commerce/product_info.php?products_id=747 |
| 21:26.13 | solar | low power. 1-3v tiny hobby ones. |
| 21:26.27 | RobotGuy | knew prpplague would have the answer |
| 21:27.31 | prpplague | solar yea you can attach motors pretty easy, but you might want to read up on H-Bridges |
| 21:27.37 | RobotGuy | Banebots FF-050 motors are very cool. Trossen Robotics sells them. |
| 21:28.35 | solar | ok. Pong |
| 21:28.55 | prpplague | solar that answer your question ? hehe |
| 21:29.15 | RobotGuy | We're playing PING PONG at the TCT World Open today, with prpplague and solor |
| 21:29.16 | RobotGuy | solar |
| 21:29.22 | solar | good enough. I was just trying to make use of the parts at hand to see if I could get this sensor running around the house on it's own |
| 21:29.31 | RobotGuy | Durn, how I manage to misspell that. |
| 21:30.00 | prpplague | solar yea, you can do it if you have some NPN's and PNP's type transitors and create a H-Bridge |
| 21:30.04 | solar | RobotGuy: it makes it eaiser. Atleast we are using somewhat of the same hardware. And the things I'm trying to learn about somewhat relate to the stuff you are doing. |
| 21:30.24 | solar | NPN are diodes? |
| 21:30.24 | RobotGuy | solar: Yes, indeed, and that's very cool. |
| 21:30.29 | RobotGuy | Transistors |
| 21:30.34 | prpplague | solar there will be plenty of google info on how to do create an H-Bridge using individual transistors |
| 21:30.46 | RobotGuy | That's what I told him too. :) |
| 21:31.09 | prpplague | solar transistors that are NPN are Negative-Positive-Negative |
| 21:31.15 | RobotGuy | solar: I found a motor control shield for Arduino. |
| 21:31.24 | solar | RobotGuy: I've got 3 556 timers handy if that helps |
| 21:31.26 | RobotGuy | I woud rather make my own though. |
| 21:31.28 | prpplague | solar transistors that are PNP are Positive-Negative-Positive |
| 21:31.45 | RobotGuy | I have a few of those also. |
| 21:31.51 | prpplague | solar where the center one is the type of polarity/voltage needed to triger the switch |
| 21:32.12 | RobotGuy | I juust got 50 2N7000 MosFETs |
| 21:32.20 | solar | prpplague: yeah I still usually have to see the pictures to understand the specs on most things. |
| 21:32.36 | prpplague | solar you ever have an electronic device uses 4 AA batteries all in a straight line |
| 21:32.39 | prpplague | solar ?? |
| 21:33.09 | prpplague | solar i.e. a flash light |
| 21:33.28 | solar | I don't think a single one uses them in series like that other than a flashlight |
| 21:34.10 | prpplague | solar ok, lets run with a flash light, lets say that it requires 4 AA's to operate |
| 21:34.40 | prpplague | solar sorry lets say 3, since that fits better with the transistor example |
| 21:34.57 | RobotGuy | Good analogy. |
| 21:35.04 | prpplague | solar ok so if you put in one battery on one side and one battery on the other, but not one in the middle |
| 21:35.13 | prpplague | solar the flashlight of course doesn't work |
| 21:35.27 | prpplague | solar if you place the 3rd battery in the middle the flashlight works |
| 21:36.01 | prpplague | solar now, what happens if you put the battery in the middle with the + side swapped with the - side, i.e. in backwards |
| 21:36.07 | prpplague | solar does the flash light work? |
| 21:36.32 | RobotGuy | raises his hand. :) |
| 21:36.43 | prpplague | RobotGuy hehe |
| 21:37.00 | prpplague | solar it doesn't work because the polarity is incorrect |
| 21:37.16 | prpplague | solar so transistors are very similliar to the way the three batteries are |
| 21:37.46 | prpplague | solar you have one connection on each end(the two first batteries in the example), and one in the middle |
| 21:38.09 | prpplague | solar when you provide a voltage to the middle one, it is like placing a battery inbetween the two other batteries |
| 21:38.42 | prpplague | solar you have two basic groups of transistors, which represent the different "directions" the batteries can be placed |
| 21:39.44 | prpplague | solar that make any sense at all? |
| 21:40.22 | prpplague | wonder if solar ran away after getting tech lecture from prpplague |
| 21:41.47 | solar | nope. I was taking pics of what I'm trying to accomplish in it's house. parts that I have handy so you can quickly say "you need to run to RS and pick up a XYZ" |
| 21:42.00 | prpplague | hehe |
| 21:42.25 | RobotGuy | He's probably looking through his toy box for new things to connect to Arduino. :D |
| 21:42.54 | prpplague | solar as to my ping, mr.herod wants to go ahead with a web carrier board for the hammer, so if you know any sysadmins that have any ideas of a small web server board, now would be time for some feedback on it |
| 21:42.57 | solar | naa. I got nearly everything I want there. I don't want to overload the little device. It's timings are already pretty off |
| 21:43.02 | RobotGuy | I found Arduino on Steroids. |
| 21:44.04 | RobotGuy | 4x memory, 32 more pins, 40 pin DIP. |
| 21:44.22 | prpplague | solar so far, we are looking at, usb host, usb slave, 2 uarts with levelshifters, probably a 4 port internal hub so you can add other usb devices on the board |
| 21:44.24 | RobotGuy | Wait, can't be 32 more pins. |
| 21:44.34 | prpplague | RobotGuy carrier board, not cpu board |
| 21:44.48 | prpplague | solar 10baseT, and spi based SD card |
| 21:44.49 | RobotGuy | prpplague: Is that Anvil? |
| 21:45.06 | prpplague | RobotGuy not sure what rusty has in mind for a name |
| 21:45.51 | RobotGuy | I call Hammer-RDP Mallet. (not mullet). |
| 21:46.45 | RobotGuy | glares at the unconnected battery supply for Arduino. |
| 21:53.08 | prpplague | ho ho hum |
| 21:59.42 | solar | prpplague: sorry I'm in and out still /jumping back and forth a bit. That work I got stuck with Friday afternoon is carrying well over into today. |
| 22:00.36 | prpplague | solar np, i understand all too well |
| 22:00.54 | solar | web carrier being a PDA like device? The M80 thing you have been working on but with a qwerty and an empty slot for a an aftermarkert telit chip if I wanted? |
| 22:01.29 | prpplague | solar hehe, naw |
| 22:01.30 | solar | ie the openmoko killer? :) |
| 22:01.32 | solar | damn |
| 22:01.58 | prpplague | solar naw, just a carrier board with the purpose of running a small webserver |
| 22:02.04 | prpplague | solar to do "something" |
| 22:02.22 | solar | a picotux alike device? |
| 22:02.31 | prpplague | solar we got about 50+ feedback items there at LWE with people wanting a small webserver |
| 22:03.21 | prpplague | solar not that small and limited, but yea |
| 22:03.31 | RobotGuy | I know how to put a webserverr on Hammer. |
| 22:03.43 | prpplague | solar more like the NSLU aka slug |
| 22:03.50 | prpplague | solar but easier to hack on |
| 22:04.22 | RobotGuy | I already did it. :) Two different servers. |
| 22:04.30 | prpplague | http://en.wikipedia.org/wiki/NSLU2 |
| 22:04.47 | solar | prpplague: for $12 in bulk you can pick up that avr32/arm9 chip. For another ~12 bucks in bulk you could add a simple eth interface. Then leave the 2x10 pins exposed. Call it a day if going for a picotux kinda design |
| 22:05.34 | solar | but I guess you need a SOC.. |
| 22:05.40 | solar | doing it with the hammer cpu? |
| 22:05.56 | RobotGuy | I already did except for having it networked. |
| 22:05.58 | prpplague | solar hehe, yea, thats what i was going to say, this would just be another carrier board for the hammer |
| 22:06.13 | prpplague | RobotGuy yea, this is more of a hardware issue than software |
| 22:06.21 | RobotGuy | Oh |
| 22:06.38 | prpplague | we just need to decide on what i/o and where to put it on the board |
| 22:06.58 | solar | prpplague: well. Take a look at the NSLU2. It offers 2 USB client ports. 1 eth port. 4 leds. Sells for ~80 |
| 22:07.11 | solar | and a beeper |
| 22:07.22 | RobotGuy | Lots of serial ports and lots of analog inputs. :) |
| 22:07.28 | solar | small (intel) flash. |
| 22:07.37 | prpplague | solar yea, thats basically what we would want to emulate |
| 22:07.47 | solar | ppl right away try to get serial and jtag access. |
| 22:08.05 | solar | so if you expose a serial port. You are off to a great start. |
| 22:08.07 | prpplague | solar should be able to do a webserver carrier with a hammer for same cost as the nail, $189 |
| 22:08.07 | RobotGuy | Yep, I always go right for the JTAGular. |
| 22:08.57 | prpplague | solar yea, what we had planned was a 10baseT, 2 uarts, 1 usb host from the hammer, 1 usb slave from the hammer, 1 4-port usb hub, sd via spi interface |
| 22:09.07 | solar | the nail has a built in 4 port usb hub right? But only one client port is exposed? |
| 22:09.59 | solar | SD = wonderful idea. The default firmware to make it easy for others should try to mount the SD and look for rootfs.(supported loopbacks) |
| 22:10.19 | solar | or try to boot off it if you can detect a bootable bit |
| 22:10.43 | solar | that would make it quite hacker friendly w/o ppl needing jtag access very often for reflashing |
| 22:10.55 | prpplague | solar the nail uses a 4-port hub, but that is for the client side, not the host side |
| 22:11.02 | solar | but opens the doors wide open for ppl to come over your house and trojan your firmware |
| 22:11.30 | prpplague | solar yea, apex supports reading the kernel from the sd card already |
| 22:11.47 | RobotGuy | sighs |
| 22:12.16 | solar | if security is a worry then perhaps the vendor could make it a jumper on the board or something to get that mode. |
| 22:12.24 | prpplague | yea |
| 22:13.27 | solar | I think a 5VDC jack or USB power would be good. If it can be made semi portable. Then it's usefulness gains. |
| 22:13.55 | RobotGuy | Attach a battery supply and have a portable web server. |
| 22:14.03 | solar | 5V or USB. On the arduino you have to use a jumper. But.. It's ok to deal with |
| 22:14.29 | RobotGuy | Yeah, http://www.robotguyschair.org |
| 22:14.36 | RobotGuy | (not a real domain) |
| 22:15.27 | RobotGuy | Roving hot spot.:) |
| 22:17.02 | RobotGuy | I have my Arduino jumpered for external power now. |
| 22:19.59 | RobotGuy | wonders if he could get a company to sponsor WiMax for his chair.. |
| 22:21.19 | RobotGuy | I cound hang a sign on my chair that says "This space for rent" :) |
| 22:25.47 | RobotGuy | Robotguy's Roving Hot Spot and Advertising Kiosk. |
| 22:27.55 | RobotGuy | Zippity Dooo Dah |
| 22:29.20 | solar | oh yeah pics |
| 22:30.14 | RobotGuy | "Your message here" |
| 22:32.01 | prpplague | solar yea, you should be able to provide an external power source, but i don't know how portable this board will be |
| 22:32.24 | prpplague | wow the #1 complaint about the hammer board at LWE was that it didn't use U-Boot |
| 22:32.31 | prpplague | which is just insane to me |
| 22:33.00 | prpplague | so now i have to compile u-boot for the hammer, but oh well |
| 22:33.04 | RobotGuy | Battery supply and WiFi = Portable |
| 22:33.27 | prpplague | RobotGuy won't be designed to be portable |
| 22:33.32 | solar | http://linbsd.net/~solar/pict0049.jpg (49-52) was the idea I was playing with. |
| 22:33.40 | solar | prpplague: nslu2 is quite portable. |
| 22:34.06 | RobotGuy | prpplague: That does not mean it won't be made portable by somebody. |
| 22:34.07 | prpplague | looks |
| 22:34.18 | solar | bit wide. Smaller than the existing hammer carrier. but not by much. More or less take away the proto area and you have a nslu2 |
| 22:34.20 | solar | on crack |
| 22:34.26 | prpplague | RobotGuy agreed, i just said it wasn't going to be designed to be portable |
| 22:35.05 | prpplague | solar kinda blurry pics, hehe |
| 22:35.12 | RobotGuy | That was my first suggestion for what is now the Hammer-RDP plus adding three pin headers for all pins. |
| 22:35.20 | solar | yeah sorry. I set on lower res |
| 22:35.39 | solar | it's a 8.1MP cam. So it kinda can take really big(size) pics |
| 22:36.03 | prpplague | solar thats doable, just gonna need some H-Bridges to do the motors |
| 22:36.29 | solar | for fwd/rev motion? otherwise I'd be limited to a single direction? |
| 22:37.08 | prpplague | solar yea, full bridge for fwd/rev , half bridge for just one direction |
| 22:37.37 | solar | half? what more do I need than power for single direction? |
| 22:37.45 | solar | other than power ? :) |
| 22:38.12 | prpplague | solar well if you want it controlled by the hammer, you need to be able to switch it on/off via a 3.3v i/o |
| 22:38.21 | prpplague | solar you could use a relay |
| 22:39.47 | solar | i think for the moment I'll be using the hammer to get/send serial cmds to the arduino(s). |
| 22:39.56 | solar | actually a few weeks out and if I enjoy myself today |
| 22:42.12 | prpplague | solar ahh should be able to find plenty of examples of running a motor with the arduino |
| 22:43.48 | prpplague | really surprised at how many people want u-boot |
| 22:48.50 | MonMotha | u-boot on an AVR? |
| 22:51.32 | prpplague | MonMotha no for the hammer |
| 22:51.55 | prpplague | MonMotha 80+ comments from LWE that they would prefer uboot |
| 22:52.15 | prpplague | MonMotha which means i need to post a patch, source, and build for the hammer |
| 22:57.33 | solar | prpplague: radio shack says they have 25A @ 50V H-Bridge( overkill) or 100V @ 8A ? |
| 22:57.48 | solar | me thinks the guy is looking at the wrong parts |
| 22:59.58 | prpplague | solar yea seems pretty high end |
| 23:00.45 | prpplague | goes to look at the radio shack site |
| 23:02.40 | prpplague | solar i'd recommend getting a cheap radio controled car, but i'm not sure how good you hacking hardware skills are |
| 23:08.36 | solar | ok done. Told the EX to pick up two remote controled cars (one for 8bucks and another 25$ one). Skip buying the h-bridge (as there is one I can probably rip out) |
| 23:08.51 | solar | and if lucky. It might have an equiv of a zigbee in it |
| 23:10.36 | solar | even if the remote sends analog signals I think an arduino has enough 7 or so a-inputs |
| 23:11.34 | solar | no 100uf 10V cap however. They attempted to sell me a 35V one at 100uf.. I've got 100uf @ 16V but don't know how to make that safe for a 9V charger |
| 23:19.02 | RobotGuy | If I wanted to make a router, would I need a separate h/w ethernet I/F for each port? |
| 23:20.56 | solar | prpplague: my hardware hacking skills of no choice but to get better than they are. Kill a few boards and I'll learn my lesson. |
| 23:20.58 | RobotGuy | I hate having to do mechanical stuff. |
| 23:21.15 | solar | leaning the lesson is why I've avoiding trying to use the nail atm for basic sensor i/o |
| 23:22.15 | RobotGuy | Hammer Carrier is better for that. |
| 23:26.21 | solar | RobotGuy: the Nail also have the 40 pinouts along the side that one could tap into to do all sorts of fun things. |
| 23:26.50 | solar | carrier looks damn fine for making the proto-type of all the things you plan to fit in a more compat space. |
| 23:33.02 | RobotGuy | solar: I know. :) |
| 23:42.11 | g1powermac | ds2, you around? |
| 23:42.30 | g1powermac | or GPSFan? |
| 23:43.24 | g1powermac | or anyone with m68k macs. . . |
| 23:46.04 | GPSFan | g1powermac: hey, how's trix... |
| 23:46.49 | g1powermac | doing well, I decided to help develop this: http://emile.sourceforge.net/index.php |
| 23:47.01 | g1powermac | so I need more m68k macs :-) |
| 23:47.39 | GPSFan | g1powermac: given up on the z2? |

| 23:51.37 | g1powermac | nice |
| 23:51.46 | g1powermac | I need to see if my mac II works |
| 23:52.10 | g1powermac | lemme know what systems you got and how much they weigh and I'll send you a UPS label |
| 23:53.06 | GPSFan | I'll go check it out tomorrow, I have the kbd & monitor too. |
| 23:53.17 | g1powermac | oh that'd be good too |
| 23:53.22 | g1powermac | I only have one mac monitor |
| 23:55.42 | g1powermac | hmm, so, a 512k mac rom has over 160k lines of assembly after disassembly |
| 23:56.12 | GPSFan | g1powermac: it's the little 640 x 480 color one, Ill take some pix too. |
| 23:56.20 | g1powermac | k, cool |
| 23:56.42 | GPSFan | and the pb 100 is 68k too. |
