Gradually, Moseley gave remote control circuitry a complete makeover, using TTL logic circuits, voltage controlled oscillators and other digital techniques. The one remaining weak link was the analog ...

Talking control In the late 1980s, Gentner Engineering came out with the VRC-1000, a revolutionary new “talking” remote control system that worked over a dial-up phone line. That changed everything ...

It’s a common scene: a dedicated radio amateur wakes up early in the morning, ambles over to their shack, and sits in the glow of vacuum tubes as they call CQ DX, trying to contact hams in ti… ...

[fahadshihab], a young tinkerer, shared his circuit design for a simple remote control using 555 timers. Using a 555 calculator, he designed a clock circuit that would run at 11.99 Hz. Two transis… ...

Radio control remained a novelty, an exciting field for experimentalists and specialists, until the launching of the Space Age and the orbiting of myriad commercial and military satellites, all ...
