Laser based night light


[the4est] put together this quick how to for making a laser based light bulb night light. First, you need to break out the black glass base of the bulb and remove the filament. Scrub the inside of the bulb and pour in the paraffin. Once it sets, you can break the glass, leaving a solid wax bulb. Hollow out the inside, insert a laser pointer, and you’ll have fine glowing night light.

Game Boy foot controller demo


This is a video of [Joey Mariano] from animal style demoing his Game Boy pedal board. He added a D15 port to the back of the Game Boy, which is wired to each of the 8 buttons. The port is connected to a breakout box for 8 piano sustain pedals. The box also provides power to the Game Boy. The Game Boy is running the Nanoloop step sequencer. If you’re wondering about the guitar sound, he’s probably using an 8-Bit Fuzz pedal.

Pegboard cable organizer


In our integrated desk post, we mentioned using pegboards and zip ties to organize cables. Lifehacker has a collection of pictures from their readers that are using this solution. We especially love [Steve Price]‘s fliptop solution pictured above. It may not look too attractive, but we’d do pretty much anything to avoid crawling under a desk.

Asus WL500GP audio hack


The Asus WL500GP wireless router runs Linux and has two USB ports. [equinoxfr] wanted to install audio support internally to the router though (translated). Luckily, it uses a VIA VT6212 4port USB controller. So, he was able to wire two more internal ports. A Brando USB soundcard is plugged into one of those ports and wired to an external headphone jack. He wanted dual RCA connectors, but they just wouldn’t fit. The router is running OpenWRT Kamikaze. MPD is used to serve music with the wymypy frontend since it has its own lightweight webserver.

Syringe logic probe, revision 2


[Travis Goodspeed] has updated his syringe based logic probe that we covered earlier. Instead of soldering to the outside, he’s using silver wire shoved into the core of the needle. A nice side benefit is the safety cap now fits. Inside the syringe are two LEDs that indicate current direction. The sharp needle makes it a lot easier to hit small traces.

Single side Arduino-ish beta board


Via [ladyada], [Raijuu] combined some ideas from [Ladyada]‘s boarduino and [evilmadscientists] Atmel business card created his own single sided (for easy etching) project board for ATMega8/128 projects. You can tell that the design is an expression of frustration from past projects; We can definitely appreciate features like separate power and multiple sockets on each pin. (We’d probably consider adding some soldering points to allow for permanent connections.)
