Obviously the best way to show you’ve pwned a piece of hardware is to run Doom on it. This time around it’s not just a hardware hack but a security hack. [Michael Jordan] demonstrates a network vulnerability on a Canon printer by making it run Doom. [Thanks to all who sent this tip to us]
Fans of the photo-resist method of PCB etching will appreciate this Bromograph built from an old all-in-one-printer. When gutted, the body of the printer makes a nice enclosure for four UV Lamps. The treated copper clad goes face-down on the scanner glass with the printed transparency between the two. [Michele’s] early testing shows really great results.
[Tom] sent in a link to this video biography of the rLab hackerspace. It shows off the space and its members but also tells the story of a tight-knit community. We enjoyed hearing that almost everything in the space is salvaged and repaired; a great way to acquire equipment on a tight budget while also building the skills of the members.
The bulbs in projectors can be quite expensive to replace. This hack adds an RC filter to the bulb and claims to greatly extend its life. Does this really work and why isn’t it built into the projector?
[Steve Maher] built a GRBL board that is the same form-factor as a DB25 connector housing. It’s basically an Arduino derivative that includes a USB connection, a separate jack for STOP and CYCLE START switches. If you’re not familiar, GRBL is an open source project that lets your drive parallel-port-based hardware with a machine that doesn’t have a parallel port.
Finally, have you heard of the ZofzPCB program before? It’s a way to visualize your gerber files in order to perform a final sanity check before sending your deign off for fabrication. [Thanks Boldport]
