Ping Pong Robot

at 10:28 pm. Filed under Complex Hacks, Cool Gadgets, Crazy Hacks, DIY Hacks, Insane Equipment


 If you hate when you don’t have a partner to play ping pong with you why not build a robot. Ulf Hoffmann is an industrial mechanic and has some creative ideas. His Ping Pong Robot (translated) is quite amazing, you can see it in action above. The videos below demonstrate the building blocks to get to where the robot is today.

Drone with a 80KV Stun Gun

at 9:46 pm. Filed under Insane Equipment, What Were They Thinking


When you get tired of flying a regular hexcopter why not kick things up a notch and install a stun gun on the thing to protect your property!

“In the video above, CUPID (short for Chaotic Unmanned Personal Intercept Drone) takes down an intern. He doesn’t get up with ease.”

Arduino Based Z Axis Laser Cutter Controller

 Arduino Based Z Axis Laser Cutter Controller


 Many laser machines have very crude table positioning for Z control. Martin Raynsford wanted to add some additional Z table control to his laser machine. An Arduino and some buttons are used to interface with the system to allow for some enhanced table height adjustment.

“The user pad has 4 buttons, one fast and one slow in either direction. If you push fast and slow at the same time the Z axis will datum in that direction, because the Z axis control system is now independent of the laser controller I’m able to adjust the Z height at any part of the program, this might not be the safest way of doing it but it’s pretty easy not to push the buttons while the laser is actually cutting. “

The Art of Watchmaking

The Art of Watchmaking


Wrist watches seem to be loosing their grasp on our wrists with the popularity of smart phones but I think the beauty of a well crafted watch will never die. You can buy a digital watch at the dollar store which would have been churned out in a factory in China or you can purchase one for hundreds of thousands of dollars. Mechanical watches require very detailed manufacturing and tolerances that are incredibly tight. The super high end watches also require lots of human interaction to finish and assemble the watch. When you think of the complexity it is amazing that you can get years of solid use out of them.

Open Enigma Project

Open Enigma Project


 Have you ever wanted to play around with an Enigma Machine? Well if you act fast you can get one of your very own. This Open Enigma Project Kickstarter by S&T GeoTronics still has 28 days to go and is already over half funded so it looks very promising. It uses an Arduino Mega to run the show so customization of the system would be very simply. The design is wonderful looking, I think it would make a great coffee table piece.

Thanks to James for sending in the tip.

How the Fadecandy LED Controller is Made

at 5:47 am. Filed under Complex Hacks, Insane Equipment


Adafruit recently took on production of the Fadecandy project that Elizabeth Scott developed. The video above is How the Fadecandy LED Controller is Made using the automated PCB production machines. There are 3 basic machines in the equipment path, the panelized PCB goes through a solder paste machine where a laser etched stencil is used to put solder in just the right locations. The board is then moved through the pick and place machine where all of the components are automatically placed, and finally it rolls through a reflow oven where all of the parts are permanently soldered in place. Only thing to do after that is snap the board off and plug it into a test jig.

DIY CNC Machine called the Ripper

at 5:24 pm. Filed under Cool Gadgets



Long time reader Maximilian Malihas built a great looking CNC machine called the Ripper. It looks nice and rigid, you can see in the video that the unit is very versatile and would be at home in any workshop. If you want to build your own there will be plans on the site soon, for now there are a ton of build pictures and documentation.

 “The 3-Axis CNC was not designed for a specific application – ripper fusions the needs required for fast shape-cutting in wood/PVC and the strength and stiffness required for milling in aluminum and copper. It brings the precision down to fractions of the human hair – and can be build using simple tools!”
