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 […]
