Inside some stylish wireless switches (including RF schematic)

One of the best things about these switches is that they use a very standard encoder chip, which means they'll work with most common eBay receivers. The EV1527 chips have a 20 bit random code (1,048,576 permutations) plus the 4 channels, so the risk of a matching code on another random remote is unlikely with well written software that tests all 24 bits. I've included the RF section for the radio hams. I'm not an expert in this area, but it strongly resembles the classic Colpitts oscillator used in many DIY FM micro transmitters. If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- http://www.bigclive.com/coffee.htm This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
