Freeform 555-timer-based breathing diode bug
I have been watching those amazing freeform creations by people like @MohitBhoite and @jipraus for some time. I examined many entries for the recent Circuit Sculpture Contest on hackaday.com and have been thinking, that I would love to build something like that, but I had been convinced that my skills are not good enough.
But skills can be trained and learned. So I finally ordered a few brass rods and tried my first freeform sculpture. Here’s the result.
Learning the hard way - DIY power measurement unit with INA219 and ATtiny85
A story about how I was reminded that impatience and impetuosity can backfire when dealing with hardware.
Building a custom keyboard - Katana60
I learned recently that there’s a huge community around making of custom mechanical keyboards. Even though building such keyboard is actually quite expensive I failed to resist the temptation and decided to build my first one.
KITTBlink2 - KITT inspired gizmo AKA Larson scanner, version 2
An improved version of my previous creation. Better and hackier!
Activity journal - progress update
Progress update about the Activity journal project.
Activity journal - designing UX
It this part I am going to dive into a short and crude UX design phase for the Activity Journal application.
It's never too late to learn C++ properly.
If you asked me a year ago to learn C++, I would politely refuse. Now I am (re)learning it.
Activity journal - a mobile application idea and a personal project kickoff
I have got an idea for an Android application during my vocation. In this article, I am elaborating on the idea and my motivation to build it.
More blinking LEDs - KITT inspired gizmo, version 1
What could I do with couple of ICs (mainly shift registers), LEDs and basic components, but without a micro-controller?
LED cube 4x4x4 with ATtiny84 and 74138
I made a LED cube. A silly thing that blinks a lot and is controlled by programmable microcontroller. But why? And how?
