Decatron stand-in

Think the swirling glow of a Decatron is cool but don’t want to deal with the voltage issues? [Osgeld] sidestepped the problem by developing a fake Decatron. Admiral Nelson (Captain Morgan’s cheaper cousin) provided the enclosure in the form of an airplane sized liquor bottle. The LEDs are common-something (not sure if it’s anode or cathode) so they end up being individually addressable through the mess of wires coming out the end. This will greatly simplify that kitchen timer we’ve been meaning to build. See the blinking lights go around and around after the break.

Mini racing cabinet

Here’s another small arcade cabinet. This time around it’s the racing simulator Daytona USA. [Pocket_lucho's] cabinet work has been featured before and he did some fine work with the control interface on this build. The wheel is from the controller of an RC car and the gear lever from a heavily used toy. He fashioned two pedals using gate hinges and a couple of leaf switches. The guts pack quite a punch with a mini ITX motherboard running the show. This will look great next to Ms. Pac-Man. Check out the video after the break.

Bassoforte and other new instruments

[Diego Stocco] makes music with instruments he assembled. For instance, his Bassoforte uses piano keys, the neck and strings from an electric bass, and what look like some cymbals. Throw in a hammer from that piano and a double bass bow (plus heavy use of audio software) and he’s in business. Big business actually, his work has been in video games such as The Conduit and in feature films like Sherlock Holmes where he worked with Hans Zimmer. Bassoforte isn’t his only invention, he’s got several more including the Experibass string family on one instrument, the Light Controlled Oscillator, and sand music using the fine aggregate along with some piezoelectric film transducers.

Connecting a Nokia 3310 LCD using an AVR

In this instructible, [wkter] takes us through the process of running a Nokia 3310 LCD display using an ATmega8.  This instructible isn’t a beginners project as he assumes you already have a strong understanding of how to work with these components and their programming languages. He is very thorough with information though, providing datasheets, pinout diagrams, and source code. Once you get this down, you could go a little further and make  Conway’s game of life.

30 Mph electric mountain bike

A 48 volt power house pushes this mountain bike at speeds up to 30Mph.  That’s a bit of a boost from many off the shelf E-bikes. [Jennifer Holt] wanted speed, and to retain the off road capabilities of her bike, so she made a custom one. As you can see in the video, this thing gets going fast and hills are no problem. She says that it will toss you off if you slam the throttle, and we believe her. We know some of you will insist on chiding her because she’s not wearing a helmet in those videos. She did manage to break her elbow offroading in the video after the break. That part is edited out though.
