| 02:36:16 | prpplague | Russ: you around? |
| 07:48:41 | mmatten | morning |
| 08:04:38 | Russ | hey prp |
| 08:04:40 | Russ | er |
| 08:04:42 | Russ | he's not here |
| 08:10:05 | mmatten | would be a bit early for him (or late) ;) |
| 08:21:56 | seletz_ | morning |
| 11:58:36 | Sammy | seletz : had take any photo ? |
| 12:00:54 | Sammy | erikm: when I download kernel into ram, and then after I flash into flash , it's show a boundless cycle write to first block , why ? |
| 12:15:01 | Sammy | see ya tomorrow ... sometime need to go ... |
| 15:09:56 | prpplague | morning all |
| 15:10:33 | prpplague | erikm: hey does the LART use a FPGA? |
| 15:17:29 | erikm | the lart doesn't |
| 15:17:36 | erikm | there are two CPLDs on the KSB, though |
| 15:18:47 | prpplague | erikm: ok thanks |
| 15:19:04 | prpplague | erikm: heard anything about baloon going into production? |
| 15:19:12 | erikm | nope |
| 15:19:53 | prpplague | erikm: bummer |
| 15:20:10 | prpplague | erikm: made your hotel arraingments yet for OLS? |
| 15:20:38 | erikm | not yet |
| 15:21:33 | prpplague | me either |
| 15:21:39 | prpplague | guess i better do that today |
| 15:35:04 | prpplague | erikm: have you worked with on of those nanoEngines? |
| 18:44:40 | Russ | hey prpplague |
| 19:02:23 | prpplague | Russ: howdy howdy |
| 19:07:45 | Russ | wouldn't happen to know much about power mosfets, would you? |
| 19:19:38 | prpplague | sorry no |
| 19:19:45 | prpplague | is hardware challenged |
| 19:44:55 | seletz | hi * |
| 19:45:43 | | what's up, Russ |
| 19:45:43 | Russ | hello |
| 19:46:02 | prpplague | howdy seletz |
| 19:46:03 | seletz | sorry for the CVS mess last tuesday :( |
| 19:46:14 | seletz | erm, |
| 19:46:30 | seletz | thursday |
| 19:46:47 | Russ | seletz: you know much about power mosfets? |
| 19:47:41 | seletz | ugh, no. Last time i heard abot FETs was in our semiconductor course (eeek!) |
| 19:48:03 | seletz | Russ: why? |
| 19:48:08 | seletz | curious |
| 19:48:26 | Russ | seletz: wondering how "safe" they are to use in automotive applications as far as voltage spikes |
| 19:48:41 | seletz | hmm, |
| 19:49:10 | seletz | you mean antistatic issues? |
| 19:49:38 | Russ | I mean voltage spikes due to the nature of the voltage system in the car |
| 19:50:51 | seletz | Russ: sorry, i guess erik is maybe of betther help here. |
| 19:52:06 | Russ | doing the artwork for someone and they speced a transistor sourcing a relay with a 80 ohm coil and 30A rating |
| 19:52:42 | Russ | 80 ohm at 12V is a lot of amperage, which means a bit transistor, and the relay is 1x1x1 |
| 19:52:50 | Russ | whereas a power mosfet is 5mmx5mm |
| 19:54:12 | Russ | and its surface mount |
| 19:55:20 | seletz | russ: hmm. that's only 125mA. But "Ohm" is'nt for coils either. Should be Henry. The unit i mean. |
| 19:56:24 | seletz | ah, i see. |
| 19:56:44 | seletz | you mean the relay coil is 80 Ohm in rsistance. Ok. |
| 19:58:09 | seletz | russ: A FET should drain considerably less, tho. |
| 20:03:08 | Russ | you are missing the point |
| 20:03:35 | Russ | to turn on the relay, the equivelent circuit would be a 80 ohm resistor hooked up to 12V and gnd |
| 20:04:09 | Russ | that is 1.8W |
| 20:04:53 | Russ | (but, yes it is 150mA, at 3.3V, its about a half watt, but at 12V, its considerably more) |
