Prototyping nRF24L01+ modules on Arduino

I start­ed look­ing at the nRF24L01 chips while plan­ning a con­troller for the sprin­kler in my back yard. They seemed like a pret­ty good option for low-cost, low-pow­er wire­less Arduino com­mu­ni­ca­tion. They’re not per­fect, but when you can buy a 10-pack of mod­ules for twelve bucks on eBay it’s easy to set­tle for not per­fect. […]

Hacking the Ikea DIODER in ten minutes flat

Last week I bought a set of DIODER lights from the Ikea down the road, pret­ty much on a whim. They’re not the cheap­est way to buy RGB strip light­ing, but I did like the mod­u­lar design. And it’s remark­ably easy to mod­i­fy the con­troller to dri­ve the sys­tem with an arduino. The sys­tem comes […]

Controlling external lighting with Arduino

The path to my front door is long and very poor­ly lit. There’s a sen­sor light mount­ed above it, but that’s nev­er worked and, liv­ing in a rental, get­ting it fixed has been a bit of a task. So I bought a roll of 3-wire LED rope light on eBay. Cable-tied it to the under­side […]

Jackson PT9723 remote power control and Arduino

The Jack­son PT9723 is yet anoth­er 433MHz remote pow­er con­trol sys­tem. I picked mine up on sale from Office­works last mon­th, who don’t seem to sell them any more. But they’re still read­i­ly avail­able online for a fair­ly mod­est price. I bought it with the inten­tion of con­trol­ling it with an Arduino. How­ev­er, inter­fac­ing with it […]
