Robotic Arm Tracks Hand Movement

Posted May 18, 2017 by Chris

"This past week, I made a robotic arm that tracks your hand in free space using a Leap Motion, Arduino, and node.js. It tracks my hand very well. It is able to pick up stuff and set it down with relatively good precision, although there is definitely some room for improvement."

Building A Traffic Light

Posted May 12, 2017 by Chris

"The traffic-light project is something we did at work (Isotope11) to monitor our software projects. We are a software development firm and we handle some large projects that have extensive test code written to make sure newly added features or changes to existing features can easily be tested by running the test code against the changes."

Domotica Controlled Room

Posted April 21, 2017 by Chris

"At first a few months ago I saw this Veear EasyVR speech recognition module, and I bought one on ebay because it looked pretty cool. When I got it I thought it might be a cool idea to control my room with it, and the idea was born to make my bedroom controlled by voice!"

The Seg Bot

Posted April 18, 2017 by Chris

"The Seg-bot is a DIY segway clone that costs around $500 to build. It will attempt to keep the rider upright at 0 degrees (level), so if you lean forward it will travel forward to correct its position – the farther you lean, the faster it will go to correct itself."

DIY Soldering Robot Project

Posted April 12, 2017 by Chris

".The DIY soldering robot which we have been building in our spare time over the past few months is now working and we have been able to solder some test Raspberry Pi expansion board headers with the machine.quot;

OSMC H-Bridge

Posted April 9, 2017 by Chris

"This is my version of the popular OSMC (open-source motor-controller) H-bridge. I have actually built several different models of this board to run various robots with, but this is the most compact version of that board."

Autoresetrrr

Posted April 6, 2017 by Chris

"AutoResetRRR is a kind electronic frustration reducing device: it cuts the power periodically to devices that can go nuts (routers, net cams, servers), but it does give a heads up. If all is well, they can shut down safely and start back up. If not, the power cycle can fix a thing or two."

Quadcopter DIY With Autopilot

Posted March 28, 2017 by Chris

"Information on how to do this is quite hard to find on the Internet, so I hope this article will make the world of flight controllers more accessible and encourage more people to contribute to ArduCopter."

FPGA Controlled RPG LED Matrix

Posted March 16, 2017 by Chris

"A dot matrix RGB LED graphic panel, managed by a FPGA-based controller board that may be separately used as a demoboard, so to evaluate the potential of the on-board Spartan 6. First installment."

PWM Dimmer for LED Lighting

Posted May 4, 2016 by Chris

"I have recently moved to a new apartment and was looking for a PWM dimmer to control some 12V LED strips. I thought that should be easy enough nowadays but it proved more difficult than I thought. All I found either didn’t meet my requirements, were uggly or expensive. So I decided to build my own, tailor-made to my needs."
