Clever Husband greeted me on my return home with – "I had to buy you a new monitor".

He took my brand new monitor, dismantled it for the screen and is making a multitouch computer.

His workplace is currently researching games created for kids with autism and this was a cheap way to create the hardware they need.

It’s only half finished, which is why I was drawing on it using a diode pinched against a battery.

Inspired by the project at metku.net/index.html?path=mods/ring-light/index_eng. Both photos combined above were of course taken with identical camera settings. This is version minus one, the proof of concept – hence the taped up battery pack (3 old 17670 lithium ions, reclaimed from a laptop battery, in series) and everything held together with epoxy resin. The centre is an empty 55mm filter ring and backing is a conveniently sized lid from a plastic tub. The two LED rings are from dealextreme.com; I used 120mm and 90mm rings, smaller sizes are also available. I wired them in parallel.

Sigh.
