My (infra-red) Remote Control unit, made some 25 years ago, uses this 12 button remote to control a variety of stuff in and outside the house. https://www.dropbox.com/s/0ixidgxjkr7nh1s/20180909-RC-Unit-1.jpg?raw=1 I want to add a new function: toggling a security light near my shed workshop. Although I have a couple of buttons still unused, I want to avoid the hassle of fresh wiring and hol...

The curtain controller I made about 12 years ago toggles the curtains to open or close on pressing a momentary push button. For holidays I improvised a circuit based on an LDR inside one of those old mechanical mains-operated timers. The LDR is flush up against its neon light. That part of my circuit has recently stopped working and I've started work on it. But meanwhile I'd welcome suggestio...


MOSFET switch - sanity check

I have a Milwaukee 12v variable speed tool with a bad control board. Rather than replace the board, I'm planning to just use a switch for single (full) speed. But the switches that I have & will fit are AC only. So, I'm thinking that I'll use the switch to control a MOSFET that will do the heavy lifting. I just want to make sure that I'm not missing anything. The plan: + ______...


Old Anelex power supply: AC on the DC

This huge, ancient power supply made by Anelex has been serving from under my shed workshop bench for about 25 years: https://www.dropbox.com/s/g11s67bb5jk7bc8/HD-Power-Supply.jpg?dl=0 It supplies a few projects around the house and garden and I generally just ignore it. But a couple of days ago I found that there is 115V AC between the case (connected to the 230V AC mains input) and all th...


DC cable puzzle

Tidying up my shed workshop I got an electric shock from a cable pair that had earlier been disconnected from its 14V DC power supply. So I'd expect it to have virtually zero voltage across it, apart from ac noise. Its destination is a garden lamp relay box about 80 ft away from the supply. For some of that distance it runs close to a mains cable (unloaded at the time). My DMM consistently...

Any suggestions for projects I could do that involves the Motorola MC6840 programmable timer module? I just received a peripheral for the Apple II that has this chip onboard. It basically allows for applications that involve timers, such as reading digital potentiometers, among other things. Thanks!
