18:02.43 | viric | What is likely to shorten the life of electrolithic capacitors? |
18:08.06 | larsc | a hammer! |
18:08.23 | viric | :) |
18:08.28 | viric | this sheeveaplug power supply... |
18:08.34 | viric | blew up the capacitors again |
18:08.45 | larsc | again? |
18:08.57 | viric | every year or half a year, time to replace some big capacitors |
18:09.20 | larsc | oh |
18:09.29 | viric | maybe I should understand the circuit instead of simply replacing them |
18:09.37 | viric | if it were open hardware... :) |
18:10.29 | roh | viric: gets to hot. |
18:10.30 | Ayla | use capacitors that support a higher Volt value |
18:11.09 | viric | I thought of that |
18:11.18 | viric | it's an easy parameter to change |
18:11.25 | viric | but a bit hard to make all fit in the case :) |
18:11.38 | roh | well.. its a design flaw |
18:11.39 | viric | one is 450V :) |
18:11.47 | viric | yes sure |
18:11.52 | viric | but I don't know th fix |
18:11.54 | viric | the fix |
18:11.57 | roh | thats the loading cap for the primary side |
18:12.06 | roh | there is no fix afaik |
18:12.51 | viric | well, last time it blew up (not the 1st time) |
18:12.51 | roh | s/loading/charging |
18:13.01 | viric | now it's another one, smaller |
18:13.06 | viric | 16V |
18:13.11 | roh | caps derate at high temperatures |
18:13.23 | viric | until 105°C all say |
18:13.34 | roh | also high rf currents can make similar effects. thats why low-esr is important in psu |
18:13.55 | roh | 105 is the higher one of 2 usual cap ratings. doesnt mean they survive long at such temps |
18:14.09 | roh | usually it should be way below 60deg C in there. |
18:14.22 | viric | on summer it gets far hotter |
18:14.35 | viric | in the box. :) |

18:14.54 | viric | so it's like something needs good ventilation. |
18:15.20 | roh | maybe you can modify it to use a external supply. how many and which secondary voltages does the psu do? |
18:15.26 | roh | 5V? 3.3? |
18:15.29 | viric | only 5V |
18:15.44 | roh | well.. then just remove the psu and add a barrel conn. |
18:15.46 | *** join/#qi-hardware wpwrak (~werner@200.169.18.6) |
18:16.04 | viric | 1amp though. |
18:16.09 | viric | or 2. |
18:16.14 | viric | let's say 2. |
18:16.27 | roh | well.. measure it and use a properly overspec-ed psu |
18:16.41 | roh | i guess a 2A psu will do fine. after all its just a 10W or so device |
18:16.44 | viric | I know it takes ~7W from 22V |
18:16.48 | viric | I know it takes ~7W from 220V |
18:17.33 | viric | I'll have to do that.. |
18:22.19 | viric | I found a power supply at home that has a usb port 5V/2A, it says. |

18:56.14 | whitequark | also, reverse polarization |
18:56.38 | whitequark | oh, I see, not the case here |
19:00.40 | viric | no, I think it's not the case |
19:00.49 | viric | I thought reverse polarization would make them blow quickly |
19:00.50 | viric | :) |
19:01.14 | whitequark | not necessarily |
19:01.24 | whitequark | suppose they're reverse polarized by -5V for 1% of the time |
19:01.37 | whitequark | (if the input voltage is 220V) |
19:01.38 | viric | as in... мгновенно |
19:01.45 | whitequark | heh |
19:02.01 | viric | ok |
19:02.26 | viric | for me it's very hard to pronounce 'мгн'. |
19:02.50 | whitequark | what's your first language? |
19:02.55 | viric | which reminds me that today I encountered a unicode character for MHz. |
19:03.01 | viric | catalan. |
19:03.44 | whitequark | mhm |
19:03.52 | viric | who thought of a single character for MHz? weird. |
19:03.54 | whitequark | what's your reason for learning Russian?.. |
19:03.58 | viric | I wonder how much more like that there are. |
19:04.04 | whitequark | (MHz) that's Unicode, they have lots of weird stuff |
19:04.21 | viric | looks like so. |
19:04.23 | whitequark | e.g. emoji. a single character for "tanabata sunrise" or something like that, I don't quite recall |
19:05.08 | viric | as for the reason... well, the cyrillic looked like funny for me, and the soviet past (so much hidden to us) also added some magic to it |
19:05.12 | whitequark | and it's not a kanji character; it's a pictogram which is only used by emoji |
19:05.29 | viric | is emoji the name of something? |
19:05.51 | viric | or your explanation looks to me a bit recursive? |
19:05.53 | whitequark | "emoji" is the name of the character set, just like "cyrillic" and "kanji" and "kana" are |
19:05.58 | viric | ah ok |
19:06.28 | whitequark | http://www.unicode.org/charts/PDF/U1F300.pdf |
19:06.31 | whitequark | one big WTF |
19:06.58 | whitequark | e.g. such pearls as |
19:07.06 | whitequark | "BABY CHICK" and "FRONT-FACING BABY CHICK" |
19:07.28 | whitequark | and different characters for "DROMEDARY CAMEL" and "BACTRIAN CAMEL". |
19:07.55 | viric | basic. |
19:07.58 | whitequark | and "EXTRATERRESTIAL ALIEN" and "ALIEN MONSTER" |
19:08.12 | viric | Well, when people can't embed tetris into their products, they do these things |
19:08.22 | viric | will there be unicode characters for tetris pieces? who knows |
19:08.37 | whitequark | I'm pretty sure there are already |
19:08.39 | whitequark | let me check... |
19:09.10 | whitequark | meh, no. what a pity. I'll consider submitting a proposal. |
19:10.34 | viric | thank you :) |
19:11.38 | viric | do you remember the DOS characters that allowed a mode like 160x120 or so, on text mode? |
19:12.01 | viric | half vertical, half horizontal, corners... |
19:12.19 | viric | I wonder what resolution unicode allows. |
19:22.01 | whitequark | it's not specified in any way |
19:22.06 | whitequark | Unicode is just a list of codepoints |
19:22.14 | whitequark | i.e. "an algorithm" |
19:22.18 | whitequark | a font is an "implementation" |
19:22.42 | viric | ok |
19:22.48 | viric | whether it is a bitmap font, or vector font. |
