    Mini TV / Oscilloscope

    I obtained one of these (20mm) from a Canon Digital8 tape camcorder recently, and a few others over the years, IF you do this, be warned, many of these take more than one input type and voltages, 5v for digital parts, 12v for small flyback+H/V Coils.Also, most camcorders from the 80's or 90's have an onscreen display generator (batt, tape time, status, etc..) some have them in the viewfinder as was the case for my Canon E708, its viewfinder drive board contains a character generator chip, and takes 8N1 ASCII serial data input 1200bps.I plan to use two of them for my quadcopters FPV video, the OSD generator in the unit will be connected to an Arduino unit that recieves my telemetry signals, then displays them onscreen

    How To Save Analog Television - Pirate TV

    PLEASE DO NOT DO THIS.In 2009 Analogue Television Broadcast was moved to several different parts of the spectrum, heres why you should not do this:1) Military Passive Radars (foreign ones) were using the 6 Mcs wide TV signals to see even stealth A/C flying everywhere2) MANY parts of the UHF spectrum formerly occupied by those noisy NTSC stations are now used for data backhaul for cell towers (LTE-DB) 3) Those cheap RF modulators are well known for causing fatal interference to the digital systems (APCO25) employed by EMS, Fire, Police, and Municipal services4) Amateur Radio is an important service, this will cause severe interference to the 70cm amateur radio bandIf you are unfortunate enough to be an RF experimenter in the USA, REALLY THINK before doing this, think "Do I live near...see more »PLEASE DO NOT DO THIS.In 2009 Analogue Television Broadcast was moved to several different parts of the spectrum, heres why you should not do this:1) Military Passive Radars (foreign ones) were using the 6 Mcs wide TV signals to see even stealth A/C flying everywhere2) MANY parts of the UHF spectrum formerly occupied by those noisy NTSC stations are now used for data backhaul for cell towers (LTE-DB) 3) Those cheap RF modulators are well known for causing fatal interference to the digital systems (APCO25) employed by EMS, Fire, Police, and Municipal services4) Amateur Radio is an important service, this will cause severe interference to the 70cm amateur radio bandIf you are unfortunate enough to be an RF experimenter in the USA, REALLY THINK before doing this, think "Do I live near an Air Force Base or Naval Air Station?" If the answer is YES dont even think about powering up an analogue video sender
