Fresh hacks every day
If you’ve ever used an extruding 3D printer, you know that the resulting prints aren’t exactly smooth. At the Southackton hackerspace [James] and [Bracken] worked out a method of smoothing the parts out using vapor. The method involves heating acetone until it forms a vapor, then exposing ABS parts to the vapor. The method only works with ABS, but … Read the rest
Vector based displays were used for arcade games in the ’70s and ’80s. A typical CRT uses raster graphics, which are displayed by deflecting a beam in a grid pattern onto a phosphor. A vector display deflects the beam in lines rather than a full grid, drawing only the needed vectors. Perhaps the best known vector game is the original … Read the rest
[Bunnie], the hardware hacker who first hacked into the original Xbox while at MIT, is releasing his book on the subject for free. The book was originally released in 2003, and delves into both the technical and legal aspects of hacking into the console.
The book is being released along with an open letter from [Bunnie]. He discusses the … Read the rest
[Brian] has brought together a powerful collection of hardware to build a robot. The end goal is to have a robot that’s controlled by a Wiimote.
The Wiimote communicates over Bluetooth with a Raspberry Pi, which is running a Python script. This script uses the CWiid Python module to communicate with the controller, and [Brian] has detailed instructions on … Read the rest
This innocent looking Maglite houses a piston and barrel, making it into a functional pneumatic BB gun. A Maglite was chosen due to its high durability, and easy access to the internals. A schrader valve sticks out of the battery cap, which allows the gun to be charged using a standard fitting. A brass tube is used as the … Read the rest
For the Deconstruction decentralized hackathon, “The FABricators” from Fab Lab Tulsa built a Street Art Bot. The robot drives around and dispenses liquid chalk in a pattern to make sidewalk art.
The FABricators’ robot is based on an electric wheelchair platform. Attached to the base is the hardware for dispensing chalk, which is controlled over wifi. The operator drives … Read the rest
Want to run your 3D printer without your laptop attached? Looking to make your hackerspace printer network accessable? OctoPrint aims to make a 3D print server for the Raspberry Pi.
The open source Python project allows you to upload and manage GCODE files on the RPi. You can then select files that you want to print, and get basic statistics … Read the rest
