Monome Case Mod: Vintage Radio

October 5, 2009 by 4 Comments

We’ve seen a lot of the Monome, a USB based controller often used as a sampler, here at Hack a Day. This is one of the more creative hacks. [brothernigel] took a Monome 40h kit and fit it inside the case of a vintage radio. The faceplate was a custom order to fit his purposes and incorporates the original radio frequency display. The USB port was well placed in the side of the wooden housing. For extra “soul”, pen and ink art adorns the insides. His work log gallery takes you through the process from start to finish.

We never noticed before, but the Monome makes a great vintage-looking-electronics project. All the lighted buttons are straight out of a ’60s military command center.

Pickle Lighting For Fun And Profit

The fantastic people at MIT have taken it upon themselves to explain how an OLED works. Their visual aide in this explanation is an electrocuted pickle. This helps describe how OLEDs are actually constructed from organic material.  Many of you probably already know how they work, but for those who don’t this video will clear up any questions you might have. Even if you do know how OLEDs work, you may learn something too. We hadn’t realized how amazingly thin the displays are.

SLI Anytime Anywhere

SLI, for those who don’t know, is the process of taking two Nvidia graphics cards and allowing them to work in parallel to render to a single monitor. In theory this doubles the power, getting more FPS for video games. Great right? Except due to encryption, only a limited amount of motherboards can actually support SLI.

That is, until now. Russian hackers at xDevs discovered that the newer encryption is based around string identifiers. This can be modified within the operating system itself, so in theory any motherboard could work. Be wary, this could brick your system; but if successful, you’ll have more power without shelling out for an officially SLI supported motherboard.

Barcode Scanner In Processing

Reader [Nikolaus] decided that instead of using an existing image based bar code decoder, he would write his own. Using the Processing language he created a scanner that parsed the black and white pattern when a bar code was centered on the image. His code then parsed that data and compared it with the initializing character to provide a reference. Currently his scanner supports three character sets of the Code 128 encoding, and provided his complete code so that others could add as they see fit. He admits that the code is a bit messy due to the lengthy character tables, but very straight forward.

Double The RAM On D-Link Router

[Pelaca] upgraded the RAM on his D-Link DIR-320 router from 32MB to 64MB. This hack is simple enough: swap out the existing RAM chip for another one and change the bios to make use of the upgrade. The actual execution is not that simple because of the pitch of the TSOP II package; you’ll need to bring your mad soldering skills to pull this off.

This reminds us of when upgrading original Xbox RAM to 128MB was all the rage. It involved the same type of hack, adding four memory chips to unpopulated positions on the motherboard. The forums are thick with people complaining that their box not working after a failed upgrade attempt. Hopefully you’ll have better luck.

Touch Sensitive Keypad

[Viacheslav] built a keypad that uses human capacitance to detect key presses. Unlike normal keys which close a physical connection, his project detects touch through the PCB substrate. He uses the analog comparator of an AVR ATmega8 to detect the moment of zero crossing and then measures the time it takes to discharge in order to detect key presses.

Mail-E Email Checker

[Totoro] sent in this cool little email notification device he made. Using a paper model of Wall-E, he added some servos and connected it to his computer using a PIC. Mail-E has independent arm rotation and head rotation. He admits that the PIC processor is major overkill and plans some upgrades such as making it wireless and using a little better suited chip to control it. Not bad for a proof of concept.
