15:59 | se6astian | I am currently in a cinema so no meeting from my side today
| |
15:59 | se6astian | Unless bertl is available but he was not sure he will be earlier
| |
16:00 | Bertl | I'm available, we can convene if anybody has anything to report
| |
16:07 | Bertl | okay, doesn't look like, so meeting cancelled today :)
| |
20:42 | anuejn | Here is some late report from my side: I recorded some further logic traces of the 5d mark II with a faster logic analyzer and think that I would have enough information to replay the traces
| |
20:43 | anuejn | I am not sure yet exactly how to proceed (what testsetup I want to build)
| |
20:43 | anuejn | i would prefer something fpga-based as thats easier for me and probably closer to what I will have in the end
| |
20:44 | anuejn | but i dont really know If I want to build a board just yet (probably similiar to the micro a simple board stacking with the z-turn lite)
| |
20:44 | anuejn | or just go for a flywire setup
| |
20:45 | anuejn | also I probably have to investigate the power supply rails a bit further (test if they are constant current or constant voltage)
| |
20:46 | anuejn | and I might want to try to get more information on the analog outputs
| |
20:46 | anuejn | thats it from me this week :)
| |
20:46 | Bertl | thanks!
| |
20:47 | anuejn | Bertl: do you have a good idea how to find out if a power-supply is constant current / voltage?
| |
20:48 | Bertl | that should be simple if you can load it differently
| |
20:48 | Bertl | i.e. add a resistive load to an existing one or try two different resitivie loads
| |
20:48 | Bertl | if it is CC, you will get different voltage but identical current
| |
20:49 | Bertl | if it is CV, you'll get different currents but identical voltage, no?
| |
20:49 | anuejn | the constant current source should decrease voltage if I decrease resistance, right?
| |
20:50 | Bertl | yep, Ohm's law V=IR
| |
20:50 | anuejn | okay yeah will try that
| |
20:50 | Bertl | with I constant, you get I = V/R
| |
20:51 | Bertl | so the ratio of Voltage to Resistance is constant
| |
20:52 | anuejn | makes sense
