Fanjita's Rants

I posted previously about a cool ATTiny project by ELM, which implemented wave table synthesis. After playing with that, I decided that at some point I'd like to take it a little further. That point came last night.

My kids' favourite tune is Twinkle Twinkle Little Star, and we usually sing it at bedtime. I recently picked up a cheap moon-shaped wall-mounted night light from Homebase for £5 (no link, sorry - it doesn't seem to be on their website. Also available from B&Q, but again, nothing on the website), and it's pretty useless in its standard form - the batteries last for no time at all, because it uses an incandescent light bulb. So I decided to put it to better use, and convert it to LED lighting, and to put in a music box version of Twinkle Twinkle at the same time.

[UPDATE: And overnight, it was chosen to be featured as an Editor's Pick!  I'm delighted.]

I just published my first ever Instructable, after being inspired by following their channel on Flipboard for the last couple of months.

Here it is : How to build your own Duplo traffic lights, using an ATTiny, switch, 3 LEDs and a few bits of Lego.
