Hello all,
I grabbed. It is OK.Technical details:
http://chdk.setepontos.com/index.php/topic,17.msg2038.html#msg2038The firmware itself
http://www.zshare.net/download/6465081c0424a0/.
Is is an SX100 1.00B, the OS is: "DRYOS version 2.3, release #0023"
If you need, I will upload the DISKBOOT.BIN and the ADC and DEC (dec has not been changed at all).
ADC and DEC is available (for me) in Linux only as executable... and of course the src as well!
The blinking process was 2 and a half hours. The "soundfile" became 700M. (again 96K sample freq. , mono, 8 bit). I use GoldWave, because it is small and efficient, and I use is for 10 years now (very rarely). With it, 2-3 hours is nothing...
The "hardware" is what I used.
- a more than 25 years old phototransistor, I could not find any info from it in the net. Make sure do not use the BASE leg (if there is), and it is working in one way MUCH better than the other way (in theory, because I did not try the other way) so emitter / collector are not interchangeable.
- a bad cheap headphone (the mic part was bad anyway, but not the wires or the plug)
- Around the phototransistor, I used blue-tag (which was white in this case) to hold the proper position AND DIRECTION the transistor.
