S-Video to RCA Cable
Jan 31st
The S Video to RCA cable is sometime hard to find and the adapter is almost every time too short. I’ve searched at my local store and haven’t found any. So I’ve decided to search on google and found some useful sites so is easy to make on your own SVideo to RCA adapter with almost no external components except of course the RCA jacks and the S Video.

CGA / SCART adapter
Nov 7th
CGA adapter / SCART has great advantages as it does not require separate power source and that uses very few external components, which can be easily adapted in the SCART connector. The signals from R, G and B pins of the CGA’s board are converted from TTL levels to SCART levels with resistors R4, R5 and R6 and entry’s impedance (75 Ω) of scart inputs. (more…)
UHF antenna amplifier
Jun 24th
This amplifier circuit is used to amplify TV signals in UHF range. It uses a low-noise transistor and gives 10 to 15 dB amplification in the frequency range from 400 MHz to 850 MHz.
The transistor must be shielded from the input components and in constructing this circuit, the wirings must be as short as possible. For best results, the cable must be directly soldered to the PCB. The circuit should be installed near the antenna and housed in a water proofed case. (more…)
Simple cable tv amplifier
Jun 18th
This cable tv amplifier is a rf-amplifier designed to be quickly installed between two coaxial cables. Both input and output impedances are compatible with 75 Ω cables. The main amplifier si T1 transistor, T2 is working as an emitter follower. The feedback bias is determined by R3 and R4. The total gain of this tv cable amplifier is 22dB. (more…)
