Commodore SX-64 Repair

at 10:05 pm. Filed under Computer Hacks


Techmoan got his hands on a few SX-64 Computers. This is the portable version of the C-64 that everyone loves. He needed to do a bit of repair but in the end he got 2 working machines. They are still going for a good price since these units are still rare compared to the regular C-64 but you can find them for sale if you look hard enough. Teamed up with a C128 VIC disk drive emulator he now has access to the entire catalog of games on a simple to use device. I still remember the day when I had boxes of disks for the C-64 and being able to fit a few games on a single disk felt like such a win.

at 10:00 pm. Filed under Computer Hacks


For everyone that has a fond memory of the C64 this tiny emulator might be of interest. The kickstarter failed but everything is listed so you can make your own.

“Hardware components

MCU: STM32F756IGK6 (ARM Cortex-M7, 216Mhz, UFBGA176)
HDMI transmitter: ADV7511W (165Mhz, LQFP-64)
SDRAM: IS42S16400J-5BL (200Mhz, 64 Mbit, FBGA)


Mathias created the MEMWA2 using a custom-designed 6-layer PCB just big enough (65 X 45 X 20mm) to fit the electronics, which include a STMicroelectronics MCU (Arm Cortex-M7 running @ 216MHz), 256Mb of Alliance Memory DRAM (200Mhz, 64 Mbit, FBGA) and an Analog Devices HDMI transmitter for wirelessly outputting audio and video to any display.”

HP Scanjet 4C Keytar

at 5:50 pm. Filed under Computer Hacks, Electronic Hacks


Using some Arduinos and a few other electronic bits this HP Scanjet 4C is made into a musical device by “playing” the stepper motor. The result is one of the best stepper motor musical items I have seen.

“You may of heard of a popular flat bed scanner named the HP Scanjet. This scanner had a hidden command set within the Scanner Control Language which allows you to send musical notes directly to the stepper motor. This is a tedious method where you have to enter the notes and durations manually into a text file (similar to G-Code on a CNC Machine). I have always used and will always use this method for my Old School music videos however I wanted to try and build a MIDI controlled stepper motor.”

18 Year Old Computer Collector Buys a IBM z890 Mainframe

at 4:00 pm. Filed under Computer Hacks, Insane Equipment, Vintage Electronics

At 18 years of age he has already been collecting for years. Most of his collection are things like Commodore and Apple computers. These can sit on a shelf and be moved around with ease. When he saw an IBM z890 Mainframe up for grabs he jumped on it. With a bit of excavation he was able to get it into his parents basement.

Drawing To Laser Engraving System

Drawing To Laser Engraving Program_4


When it comes to converting something drawn to a laser etched image there are often quite a few steps needed. Martin Raynsford has built this Drawing To Laser Engraving System to allow him to easily go from drawing to laser etched images by using a bit of hardware and some custom software. Of course you can do this type of thing manually like was done in the Halloween Hanging Mobile Project many moons ago but there is something great when the process is automated.

“The third and final project from this years maker faire was a webcam capture program that would easily digitize children’s drawings and then send them down to the laser cutter for engraving. The webcam holder with led lighting to illuminate the drawing. I used a c# wrapper for the open CV library to capture images from the webcam, a little bit of filtering to remove pixels that weren’t black enough. The image was then converted to G Code, and transferred to a GRBL controller that was wired into the Greyfin laser cutter. The G Code simply drives the laser to the next black pixel and burns a single dot for each pixel, repeat for each black pixel in the image.”

Table Tennis Trainer Project

at 9:35 pm. Filed under Complex Hacks, Computer Hacks, Cool Gadgets, DIY Hacks, Electronic Hacks, Game Hacks, Insane Equipment



If you enjoy table tennis this trainer might be a great next project. Thomas Mayer created this as his bachelor thesis project. Two Playstation CL-eye cameras are used to view the play area and track the ball. A project is then used to display game elements that the players can interact with to play many game scenarios. The game was created using VVVV which is a visual/textual live-programming environment for easy prototyping and development.

“The basic idea of my bachelor thesis was to track the ping pong ball in realtime to create data visualisations for trainers and players. After a few weeks of working I started developing a projected mapped interface for the ping pong table to show the collected data. By projecting game obstacles on the surface I figured out that I can change the game play totally.”

DIY Volume Control Builds

at 12:22 am. Filed under Computer Hacks, Cool Gadgets, DIY Hacks, Electronic Hacks



If you are tired of reaching for your tiny volume control knob to adjust your music when using your computer look no further than these projects by Engineering Nonsense and DIY Perks. The top one uses a DIGISpark board and a rotary encoder to adjust the volume via USB and the one below uses a potentiometer to adjust the analog output of your signal feeding your amplifier.
