| 15:18.04 | g1powermac | don't need big cells, just looking for a cheaper replacement for this smallish panel/cell that puts out 3v at 225ma for an embedded project |
| 15:18.17 | g1powermac | the one I currently have costs about $9 a piece |
| 15:19.06 | g1powermac | the one I currently have is the top one: http://www.futurlec.com/Solar_Panel.shtml |

| 15:31.06 | g1powermac | never heard of aliexpress before |

| 15:35.37 | SpeedEvil | It's not quite ebay - though it has similarities |
| 15:35.43 | g1powermac | what kind of guarantees do they provide if you don't receive what you ordered? |
| 15:37.42 | g1powermac | especially likes this one: http://www.aliexpress.com/item/50pcs-lot-Epoxy-Resin-75-60mm-3V-170mA-Small-Solar-Panel/1318695299.html |
| 15:37.51 | g1powermac | $3.10 a piece, perfect pricing |
| 15:38.46 | av500 | orders from ali all the time |
| 15:39.03 | SpeedEvil | av500: generally good results? |
| 15:39.13 | av500 | so far yes |
| 15:39.21 | av500 | they dont want negative reviews |
| 15:39.27 | av500 | so they usually are forthcoming |
| 15:39.32 | SpeedEvil | How does shipping work - do they get a kickback? |
| 15:39.35 | SpeedEvil | http://www.aliexpress.com/item/Three-Target-Borosilicate-Glass-3-3-Solar-Vacuum-Tube-Spare-Parts-of-Solar-Water-Heater/1538929171.html |
| 15:39.45 | av500 | SpeedEvil: kickback? |
| 15:39.56 | SpeedEvil | I find it hard to believe that if you turn up at the factory, they'll give you those for $38 for 10. |
| 15:39.56 | av500 | I usually pick free shipping |
| 15:40.00 | av500 | its sent registered |
| 15:40.07 | av500 | even has tracking |
| 15:40.15 | av500 | though that says "in limbo" most of the time :) |
| 15:40.19 | SpeedEvil | The price is $38, the shipping is $250 |
| 15:40.25 | av500 | but they have proof of deliver |
| 15:40.26 | av500 | y |
| 15:40.36 | SpeedEvil | Leading to the obvious question of is the shipping cost real. |
| 15:40.45 | av500 | I dont order $125 parts |
| 15:40.50 | av500 | I dont oder over $20 |
| 15:40.57 | av500 | since thats the customs limit |
| 15:41.00 | SpeedEvil | That 'part' is $38 |
| 15:41.37 | av500 | its huge glass tubes |
| 15:41.49 | SpeedEvil | Well, yes. |
| 15:41.55 | av500 | its expensive to ship |
| 15:41.59 | SpeedEvil | I have extreme doubts that they are actually $3.8 |
| 15:42.04 | av500 | try some free shipping offers |
| 15:42.09 | av500 | and pick EMS instead |
| 15:42.15 | av500 | or another carrier |
| 15:42.26 | av500 | its usually expensive |
| 15:42.29 | SpeedEvil | Maybe they are... |
| 15:42.32 | SpeedEvil | http://www.aliexpress.com/item/AL-N-AL-solar-water/332872692.html |
| 15:42.41 | av500 | I sent a 2poind thing from the US to german for $50 |
| 15:42.43 | av500 | 2 pound |
| 15:42.46 | SpeedEvil | Damn that's cheap. |
| 15:43.18 | av500 | I never tried expensive stuff |
| 15:43.32 | av500 | only order things that are expendable |
| 15:43.34 | g1powermac | av500, are you in the US? you get hit with customs charges over $20? |
| 15:44.04 | av500 | no |
| 15:44.05 | av500 | Germany |
| 15:44.14 | g1powermac | ah |
| 15:44.14 | av500 | the limit is €23 for import VAT |
| 15:44.23 | av500 | and €150 or so for customs |
| 15:44.30 | av500 | but not all items are taxed |

| 21:28.43 | KiriKari | So, programming a microcontroller without an RTOS when you have a lot of timing to consider is quite a nightmare. It is hard to make timing dependencies explicit in the code. Very easy to create subtle bugs that go through all testing without notice then kill someone in the real world. |
| 21:30.16 | devilsadvocate | KiriKari: programming it _with_ an RTOS isn't necessarily safer in that regard. |
| 21:31.19 | devilsadvocate | KiriKari: I'm of the opinion that getting things right when theres a lot of timing to consider is more a matter of knowing what timing _isnt_ important. |
| 21:32.55 | *** join/#edev landley (~landley@70.114.134.56) |
| 21:33.50 | g1powermac | I also would think doing all timing critical stuff in asm with good knowledge of the architecture would be the only way to do it safely |
| 21:34.57 | devilsadvocate | yes, but if you do everything in asm and you'll most definitely have a million bugs lying in wait |
| 21:35.40 | g1powermac | myeah, true |
| 21:35.58 | g1powermac | you'd have to compartmentalize the asm to mission critical areas only |
| 21:36.03 | devilsadvocate | and asm is really only great for short term timing. it sucks if you need longer term timing, like multiple 'threads' of events with periods in the order of seconds or minutes |
| 21:36.33 | g1powermac | ya, that's true |
| 21:36.56 | g1powermac | I've only ever had to use it for critical bit-banged custom protocols |
| 21:37.04 | devilsadvocate | yeah |
| 21:37.26 | devilsadvocate | faking a parallel bus to an image sensor can be an interesting experience |
| 21:37.31 | g1powermac | and even then I had race conditions |
