OK I decided to make my own TVBGone from the Minipov3 mod schematics. I figured I would go this route since I had a tiny2313 from my minipov kit. I went to Skycraft here in Orlando and got all the parts including a perfect case to put it all in for $5.00.
I believe I got all the right parts but I'm not sure. From the schematics I couldn't tell if D1 and D2 where LEDs or standard (non LED) diodes. Not sure but I thought LEDs are suppose to be marked with a couple of arrows.
I'm also not sure where to add the push button and or a switch. Any help would be gladdy appreciated.

***One more thing. Has anyone thought of modding a TVBGone to also be used as a jammer?***

It should be as easy as writing new firmware for the arv but I would not have a clue how to do it ?purpulhaze wrote:***One more thing. Has anyone thought of modding a TVBGone to also be used as a jammer?***

I had a small keyring jammer like this one http://www.stupid.com/stat/JAMR.html
It worked well with tv's but would not block sky (uk satellite tv)
There must be a common (ish) carrier wave or these toys would not work at all

Most remotes are 36 to 40 kHz, so strong 38 kHz will interfere with them.
In general....
Philips - 36 kHz
Sony - 40 kHz
RCA - 56 kHz
B&O - 455 kHz
Almost everything else - 38 kHz

Your not wrong there are different frequency's but there must be one that is more common then the rest or these toys would not work.magician13134 wrote:Ooh, nice! I guess I'm wrong again.
Or maybe a centre frequency transmitting a strong blocking signal say 36khz for example is enough to block frequency's above and below itself I don't know I'm only guessing
edit oPossum beat me to it

Re: Making TVBGone from MiniPOV3 mod schematics help...
I'm not sure either about writing the firmware so that it could do both. So I'm thinking of maybe adding another small board with the necessary parts along with some extra switches and button to my box.jasonx wrote:It should be as easy as writing new firmware for the arv but I would not have a clue how to do it ?purpulhaze wrote:***One more thing.

D1, D2 and D3 are 3 Volt zener diodes. They limit the voltage from the serial port to prevent damage to the microcontroller.purpulhaze wrote:From the schematics I couldn't tell if D1 and D2 where LEDs or standard (non LED) diodes.
You can add a switch in series with the battery.I'm also not sure where to add the push button and or a switch. Any help would be gladdy appreciated.
