[20:35:18] <jepler> I hope Chris Morley can handle criticism. At the risk of mixing metaphors, the ground he's treading on is one of my sacred cows
[20:35:41] <jepler> the other problem is that I think I can do no wrong when it comes to creating user interfaces
[21:52:16] <tomaw> [Global Notice] Hi all. Our EU to US connectively dropped for a moment there generating a rather messy split. From what we can tell it seems to be resolved so sorry for the noise and thanks for using freenode!
[22:47:52] <skunkworks_> heh - it takes 2 AA batteries to trip the 100mv current limit. (only works for a few seconds.. ) ;) Across the .015 ohm resistor
[22:49:27] <skunkworks_> so.. that part seems to be working also :)
[22:53:19] <skunkworks_> bbl
[23:07:37] <jepler> A pair is more than enough to source 10+A (initally closer to a
[23:07:37] <jepler> 50-100A transient spark) for plenty long enough to reach red heat
[23:07:37] <jepler> burning off wire insulation and PCB tracks. The chemistry starts to
[23:07:37] <jepler> get out of hand pretty quickly when only the cells internal resistance
[23:07:37] <jepler> is the limiting factor. Heat gases, boiling electrolyte, venting and
[23:07:39] <jepler> then explosion releasing cell contents. Sanyo reckon 1.2v and 0.025
[23:07:41] <jepler> ohm at so around 50A 1000Hz. I have seen higher initial instantaneous
[23:07:44] <jepler> short circuit currents than that.
[23:13:04] <CIA-1> EMC: 03jepler 07TRUNK * 10emc2/docs/src/ (checklinks.py l2h.xsl): I've been building the website html docs with these changes for ages
[23:30:24] <CIA-1> EMC: 03jepler 07TRUNK * 10emc2/docs/src/checklinks.py: quiet
