Well, they turned up this morning and while I’d never want it to be said that I didn’t think they were dangerous – they LOOK dangerous – on the other hand as long as everything is insulated and you’re not planning on touching anything – these are CHEAP and these worth checking out on Ebay. You may recall I sent off a little while ago to China for some 3v3 power supplies to power the ESP8266 boards with (the link is in the blog). If it is at works I could see a board coming on! Here is some more info and a diagram. I’ve ordered one just to see what size it is – I’m hoping this surface mount version is the same size as the normal DIP… time will tell.

The best I’ve seen up to now is £1.97 with free postage here. Right now they are marginally more expensive than the cheapest Chinese relays and even very slightly more expensive than some solid state relays – but the size has to make it all worthwhile?ĭigikey have the larger one at 1.18 but the postage kills that option – you have to wonder what their marketing people are thinking about – 1.18 for the chip – 12.00 for postage – come on guys – it’ll fit in an envelope!!! Given the very small size of our ESP-01 boards and the equally small size of the mains power supplies I found earlier, these would appear to be an ideal companion. Seems unbelievable but that’s the claim – sensible you could certainly run a typical mains light. The PR26MF22NSZ and it’s larger cousin the PR39MF22NSZ are miniature 8-pin devices which look for all the world like any other 8-pin chip – but are able to switch mains power at up to 0.9amps – i.e. One of the guys who looks in here re-blogged something of mine and I thought I’d take a look at his site – and discovered these: This is my original blog – all of the material in here has been moved to the now very popular – you can find all the older material, some of it updated – and a whole load of new stuff – at
