After a few months of slowly working on this project, I am finally releasing Rad Lines, a free tool for generating vector line artworks for plotting / laser engraving / CNC machining or marketing purposes. The tool is available at https://msurguy.github.io/rad-lines/ The source code is athttps://github.com/msurguy/rad-lines What can you do with it? This tool is particularly good […]
In this post I’d like to review another product from a company that’s been making tons of products for makers, engineers, students and tinkerers like me. Elegoo, a company from Shenzehen(China), is known for its commitment to open source, a variety of products for STEM students, detailed guides in multiple languages and very low prices. They […]

As you might know, I’ve been shifting my career focus from software engineering to hardware design and manufacturing. Specifically designing, prototyping, testing and manufacturing of connected devices. During the last two years I’ve been purchasing various tools, micro controllers, electronic parts and kits to help me design and prototype the hardware as I imagine it. […]
In this post I will share my impressions of Monoprice Maker Select V2 3D printer, otherwise known as Wanhao Duplicator i3. I got one in June of 2016 and have been using it for more than 10 months, printing hundreds upon hundreds of various 3D models. This printer costs around $300 on Amazon (also available on Monoprice […]
In part 1 and part 2 of this series I went over the following uses for Raspberry Pi Zero: Running a web server Connecting IoT devices with MQTT Putting Raspberry Pi Zero on a drone Making a smart art frame displaying images, video or WebGL content Building a security camera Making a Nixie Clock or ticker […]
In part 1 of this series (which you can find here) I went over these 4 uses of Raspberry Pi Zero: Running a web server Connect IoT devices with MQTT Put Raspberry Pi Zero on a drone Make a smart art frame displaying images, video or WebGL content This post will bring up another 4 […]
Raspberry Pi Zero, a tiny (65 mm × 30 mm) $5 computer (!!!) that was launched in November 2015 is gaining popularity and is constantly sold out from all suppliers. I was lucky to get my hands on a couple of these tiny but powerful boards and wanted to share some ideas of what you could make […]
A couple months ago I was playing with my Arduino Uno and I was wondering, what is the smallest Arduino that I could find these days? So fast forward, I am holding Femtoduino, smallest Arduino that I was able to find without braking my budget. What is Femtoduino? It is VERY small Arduino compatible board […]
This week I was playing with one of my toys – Syma S107G R/C Helicopter and a 808 Car Key Chain Spy Camera Recorder 720*480 and I put together a small video that shows how much fun it could be, check it out below: The whole setup could be purchased for 25$ if you shop around! […]
Here’s something I made for fun a couple months ago and I need to make it again soon so I’m posting schematics and Source code for anyone to download and make their own fun toy with Arduino. Parts list: Arduino Uno Original Wii Nunchuck Nunchuk to Arduino adapter (link below) Laser pointer 2 mini Servos […]
I posted this as instructable at instructables.com/id/Wind-your-own-coils-quickly/ Ever needed to wind a coil quickly? Coils can be used to make actuators, electromagnets, and even to communicate energy! I use small copper coils in my micro RC airplanes and I wind my own coils quickly with this tip. (See some of the planes I built on my […]
