Burning concrete

I'm fooling around with concrete and here is my second try. A concrete candle stand.
So useful!

Next up: A lamp. (Did you guess?)

RGB ring clock

Another project done over christmas! A simple LED clock for the kitchen wall. And with short term countdown function controlled by touching the aluminium frame.

red = hour
green = minute
blue = second
yellow = alarm

I've wanted to do a Arduino based clock for some time and had a strip with 60x RGB LEDs with WS2811 controller sitting on my shelf. I wanted to use a external RTC chip to get an exact time and found a cheap DS3231 board on eBay.

The outer and inner rings are made out of 1mm thick, 15mm wide aluminium which I hand bend into shape. The white diffusing front is a 6mm depron piece. Being unable to cut it into the right shape, I've heated up the aluminum rings to 200° and pressed them into the foam. Worked like a charm.

Here is a video of the clock and the operation of the countdown:

Sorry for the dimness, but my cam was overwhelmed by the bright LEDs.

The code and schematics are on github here. I build in two touch inputs (another one to decrement the countdown), but if both are touched at the same time the thing goes haywire and doesn't stop feeling the touch. Only happens with a cheap 5v power brick.

Disapproving wire lamp

I'm trying out a method to craft 3-dimensional shapes. Cloth over soldered, hand-bend wire pieces.
This is my first prototype. Looks not happy with itself.

The frame took about 20 minutes, real easy.

The cloth took longer, I really have no experience working with that stuff. I found no way to avoid the folds in the sides. I made the best out of it by using them as eyes.

But the method is sound. I think I will try something bigger.

Christmas roast

I didn't really want to go into food blogging... but come on, this is art! =)
Slow roasted at 80° C at nearly 5 hours. Yum!


A bit late, but here is my christmas picture.
I got a Lomography experimental lens kit from the Awesome Other for christmas!

Fun! =)
