Hey MacGuyver.. is that CARDBOARD?!!
j/k.. as long as it works.. good job =)
if you think thats not pretty take a look at my IR receiver:Originally Posted by jimbonzzz
Also, thanks for adding in the mute/mode function to the software. When do you plan to release the new version?
Yes, that's correct! Sorry about that. thanks a lot for pointing this out. I just updated the schematic...Originally Posted by tj!2k4
It is! Oh, that is just too funny. Great work, Tred.Originally Posted by tj!2k4
This is a great thread.....lol! keep up the great work guys, can't wait to see a something finished soon

Probably the best way to do it would be to connect a 9V battery to it for power, instead of getting power from pin 7 of the db9. Then:
On the RXD line on the DB9 that connects to the collector of the 3906, you should have 0V. ON the base, it should be between 4.5-5V. Connect a jumper with a resistor (10-30K works) between the transistor base and ground. With this connected, the voltage on the base should drop slightly and turn the transistor on. The RXD line should then be the same as the voltage on your zener.
Hope this helps...
Jim - does that mean that the V1 is powered directly from the PC without the need for the cigarette lighter power adapter?Originally Posted by jimbonzzz
I think he is trying to tell you to use a 9v to power the circuit to make measurements.Originally Posted by tj!2k4
