Gaming has infiltrated everything around us. It seems that any time a control interface is needed, the first thought to many current hacker’s minds are the familiar controls from the video games we grew up with. In this example, [eljaywasi] needed a way to control the wavelength of light coming out of a laser. We don’t know exactly how he’s actually changing the wavelength, but we do know he’s using an SNES gamepad as his interface. You can see a red and a blue LED located on the front of the pad, so it may be that two buttons would have sufficed. We don’t care, we like the SNES pad better.

More old computers on FPGAs!
[Andy] loves his Memotech MTX computer. It’s an oldie with a Z80 running at 4MHz; the perfect target for an FPGA port. The ReMemotech has everything the old one has – cassette interface and all – and can run up to six times faster than the original.

If you’re going to build a jukebox, why not go all out? Here’s a touch screen jukeboxwith an LCARS skin. Yep, the same interface found on Star Trek: The Next Generation.
New desktop wallpaper for you
[McMonster] found a great pair of blog posts (1, 2) showing what ancient ICs look like without their casing. Since these were CERDIP packages (two ceramic plates glued together) they were exceptionally easy to take apart leaving the entire chip intact. Pages are in Polish, but there’s a Google Translate button on the sidebar
Cheap and easy Arduino wi-fi
Quick quiz: what’s the easiest way to get data onto an Arduino wirelessly? XBees? GSM modules? Nope, just get a wireless router and an Ethernet shield. The Ethernet module only cost [Doss] $20, and we’re sure Hackaday readers have a spare wireless router around somewhere.
Chiptunes! Chiptunes I say!
[mdmoose29] has been working on making a custom SNES cartridge for a dubstep artist (tell us more, [moose]…). In his search for programming tools, he found theSNES Game Maker. We tried it out for a bit and it’s still a very unrefined beta. Still, making SNES programming easier is awesome.
You people are awesome. Here’s six things for a links post.
[Valentin] made a night vision monocular from an old VHS camcorder, a small spy camera, and a handful of infrared LEDs. Here’s a video of [Valentin]‘s build in action.
Wireless controllers for all your retro systems
Remember those old wireless controllers made for the consoles of our youth like the NES and Super Nintendo? They didn’t work well, mostly owing to the fact they were built using the same infrared technology that is found in a remote control. Now that all the modern consoles are wireless, [micro] over at the nftgames forum decided to update his classic systems for wireless control.
The transmitters and receivers are built around an nRF24L01+ radio module that operates in the 2.4 GHz band. [micro] has the process of converting his controllers down to a science. He cuts the cord and wires the controller up to an AVR running at 16 MHz. The AVR sends this to the receiver where the button presses are sent through the original controller port. Basically, [micro] recreated a WaveBird controller for his NES, SNES, Saturn and N64.
The controllers are powered by internal lithium batteries, but the charging ICs are too expensive to put in each controller. To solve this problem, [micro] crafted a small external charging circuit that plugs into a 3.5mm jack on each controller. Check out [micro]’s controller demo after the break.
