01:30 AM rue_bed: http://www.kiblerelectronics.com/bob/app_notes/note11/images/schematic1_zvs_driver.png
02:32 AM rue_bed: ok, I think I got it
02:33 AM rue_bed: a library that will tell you your closest standard resistor value
02:33 AM rue_bed: you give it a value and tell it what series(s) to check
06:12 AM polprog: the project backlog is real. ive got a yellow notetaking widget on my phone
06:12 AM polprog: it says "post about sun connectors; get a bracket for the trident"
06:13 AM polprog: i noted the sun thing when i was working in the summer (we have a lot of sun stuff in "prod")
06:13 AM polprog: well, "a lot"
06:14 AM polprog: quite a lot for this day and age
10:27 AM rue_: heh
10:40 AM rue_bed: oh drat
10:40 AM rue_bed: I think capacitors use E6
10:41 AM rue_bed: http://www.resistorguide.com/resistor-values/
10:41 AM rue_bed: and or E12
10:41 AM rue_bed: hmm
10:41 AM rue_bed: guess I should implement them too then
10:51 AM rue_bed: ok, now, why did I write that?
10:51 AM rue_bed: oh, I was going to do an RC filer library
10:26 PM Tom_L: too quiet.
11:04 PM rue_: just finished supper
11:04 PM rue_: wrote an RC library
11:04 PM rue_: n.E = 10;
11:04 PM rue_: n.C = 0.000001; // 1uF
11:04 PM rue_: n.R = 10000; // 10k
11:04 PM rue_: n.V0 = 5;
11:04 PM rue_:
11:04 PM rue_: t = 0.001; // 1ms
11:04 PM rue_: for ( i = 0; i<100; i++) {
11:05 PM rue_: timeStep( &n, t); printf("%f \n", n.V0);
11:05 PM rue_: }
11:05 PM rue_: now, if I can find my PCM library, I can write code to make 1 bit audio streams
11:06 PM Tom_L: been just over a month... i should start checking the mailbox soon
11:06 PM rue_: ?
11:06 PM rue_: and I think a week was a long time
11:08 PM Tom_L: what do you need an RC library for?
11:08 PM rue_: converting .wav files to 1 bit audio
11:09 PM rue_: you run 1bit thru a low-ass to get your audio
11:09 PM rue_: but its not pwm
11:09 PM rue_: they use it on CDs
11:12 PM Tom_L: by the time it arrives fpga will be as outdated as germanium transistors...
11:23 PM rue_: your fine
