The idea was quite simple. Buy a linear actuator from OpenBuilds with a stepper motor, attach a camera on top of it, two tripods below, assemble a control box with some Arduino-compatible, WiFi-enabled board and write an Android application that would...
2020-11-16 Downloaded libft4222-linux-1.4.4.9.tgz and unzipped it. Ran the command: sudo ./install4222.sh and got no complaints. In the examples/get-version.c file, there are instructions for Linux: cc get-version.c -lft4222 -Wl,-rpath,/usr/local/lib...
DC to DC converters are quite popular among electronic enthusiasts and are widely used within the industry. There are three major types of non-isolated DC to DC converters: buck, boost, and buck-boost. In this article/video, I used there major components...
This is a better version of a Raspberry Pi Police Radio as we are using OP25 alone, in lieu of DSD paired with GQRX. The DSD/GQRX combo was initally chosen because of its visual impression, however OP25 works much better, it doesnt suffer from having...
DisassemblyGetting the Pidock 400 apart was far easier than I thought it would be. It looked like there was super glue holding the front corners together, but it was just some crappy plastic work. It's held together by clips and quite easy to get into...
The story behind this project In the past decade, we have utilized our superpowers to address various issues all around the world, whether it be creating tools to assist people with disabilities, traversing the depths of the ocean with exploration robots,...
Everyone respected my hacker alias and called me 'crip' when I arrived...even got a nametag: "Crip Lishus" - hellyeah! (Given names are so boring and prescribed. It's nice to reinvent ourselves and our identity to match what we like and...
Pi projects are represented by a great variety nowadays. Thus, this great diversity of things to do with Raspberry Pi scales up during such days as Christmas holidays. This happens not only due to the amount of free time that avid makers usually have...

Background When we think about the dawn of the personal computer era, names like Apple, Commodore, Radio Shack, and Sinclair come to mind. That's because these companies were the big winners in this new market, selling millions of personal computers...
Four way scrolling, all easily done with one finger. My first Arduino sketch attempt in the previous project log was awful, but a milestone for me. I really love the touch sensors now that I am more familiar with them. The Teensy 3.1 has twelve touch...
Long time ago I ordered several ESP8266 modules (ESP-201) for my yet-to-be-made home automation system. Not long before that time I had Wi-Fi security related project on "big" PCs. Which inevitably brought me to well known Kali system. So, idea to use...
This Project log shall bring you towards my personal reasoning behind why I pick this part and not that. Even before starting this project I already knew that this gonna cost me quite some bucks, where technically I can just spend it on high-end mechanical...
