00:10 rue_house katsmeow-afk, technically, thats a tiny house, its all garage
00:10 katsmeow-afk ok
00:16 rue_house void SendBits (unsigned int bits) {
00:16 rue_house unsigned int temp;
00:16 rue_house for (temp = (1<<15); temp != 0; temp >>= 1) {
00:16 rue_house if ((temp & bits)!= 0) {
00:16 rue_house DataH();
00:16 rue_house } else {
00:16 rue_house DataL();
00:16 rue_house }
00:16 rue_house ClockPulse();
00:16 rue_house }
00:16 rue_house }
00:16 rue_house this code comes up a lot
00:16 rue_house I really need to put it in a library
13:17 tsmeow-afk swallows sinus p
13:59 katsmeow ever notice there's 1000's of 120vac to +12vdc switchers, but no 120vac to -12vdc switchers?
18:07 rue_shop3 isolated output
18:07 rue_shop3 + should be groundable
18:07 rue_shop3 sometimes
18:07 rue_shop3 an ATX power supply has one little wire that bonds the outputs to ground
18:07 rue_shop3 if you cut it, you can use it as a floating output
18:13 Tom_itx there are -12v switchers
18:13 Tom_itx i think they're usually tied with other voltages though
18:16 rue_shop3 how amny amps kat?
22:40 rue_shop3 katsmeow-afk, hows project?
22:43 katsmeow-afk :-(
22:43 rue_shop3 no joy today?
22:44 katsmeow-afk correct
22:45 rue_shop3 hmm
22:45 rue_shop3 the fancy votlage divider for my power supply backfeeds power to the output
22:45 rue_shop3 so I either need to come up with something else of buffer it
22:46 rue_shop3 but I cant use an op-amp to buffer it cause the votlage is too high for anything I have
22:46 katsmeow-afk backfeeds?
22:48 rue_shop3 yea, it pulls up on the output voltage
22:49 katsmeow-afk hardly a divider if it adds to it
23:16 tsmeow-afk is stillwaitog on the schem
23:16 katsmeow-afk a divider that makes power would be patentable, praps
23:26 rue_shop3 the divider was against a positive bias that was screwing things up
23:27 katsmeow-afk o
23:45 katsmeow-afk not finding humor on imgur today
23:47 katsmeow-afk for zhanx, if he returns here : http://imgur.com/gallery/HljHY5b
