Visual cryptography that hides a piece of history
Due to recent events in world politics, I decided to take a look back and make an implementation of 3D-printed visual cryptography. There were some challenges as original model was designed for printing onto overhead transparencies, which are pretty much obsolete tech today.

In the series of don’t-we-already-have-more-than-enough-of-these-gizmos: Today I made a simple power conscious cloud-connected weather sensor. While the design itself is trivial, it seems that ready-made devices available seriously lack in connection options and customisability – while doing something like this is a simple matter of programming™.
Clocks and timers are boring you say? Yes they are, and there are plenty of existing implementations. So, against intuition: let’s reinvent yet another egg timer to see how the idea twists with semi-analog circular LED-display-gauge-thingie.
Panic? Get up? Or stay in bed and continue sleep?
Ok, so sandwiching a clock on clock wasn’t the greatest idea there – what would be the next marginally smarter idea? Adding wake up alarm! In the vast sea of alarm implementations there isn’t much to be celebrated in terms of unique and clever design. So going for the context around it: How about hose dark moments in the middle of night when one suddenly wakes up wondering if the alarm goes off at the next moment.
Ikea wall clock with electronics installed to backside. Below motion sensor without casing.
It is 2016 and we are about to have flying cars soon, it would about the time to start turning old non-smart objects to smart ones. How would one make a wall clock smarter, say by an epsilon?
For long I have played with the idea on turning the most mundane objects into something completely different – so when I saw ¢ 50 Ikea RUSCH wall clock, made from semi-transparent plastic I knew it would be an opportunity to add some oddball functionality there. Ikea tuning it is, lets start putting the steroids in.
Here in KL fireworks are almost dai^H^H^H nightly fun at this time of year (new year, Chinese new year, birthday party, wedding – you name it, there is probably good reason to fire off a shell or two).
In the spirit of New Year and those tons of fireworks exploding out, and in the spirit of over-the-air updates and in the spirit of reusing existing designs – I coded rudimentary fireworks emulation onto my xmas tree LED strip. Continue reading
It is holiday season, and I see a pattern with several of my friends. They have started tuning their xmas tree lights. Thus, challenge accepted. Now, I am not going for excessive amount of lights; 240 RGB-pixels are plenty for me,instead I’ll go for the tech in it.
