CNC Brought To You By Zip Ties

January 17, 2010 by Jakob Griffith 22 Comments

Gimp skillz.

[lucassiglo21] let us know about his finished 3 axis CNC (Translation via Google). While home CNCs are nothing new, we really liked this masterpiece. The CNC is entirely custom, from the electronic control boards (connected to a PC via parallel port) to the physical mill (with an end result of 30x30x15cm workable area). Our favorite part is the use of screw/band clamp zip ties to hold the Dremel – a true showing of hacker geekyness. For those who haven’t seen a CNC drill a circle before (and honestly, who hasn’t?), check a video after the break.

ProtoDeck – MIDIBOX Based Controller

January 14, 2010 by Jakob Griffith 6 Comments

[Julien] let us know about his ProtoDeck. A MIDIBOX based controller for Ableton Live using a Big Max for live patch interface.

One thing that we have seen is less and less hacks for are MIDIbox projects. It is no wonder, considering now a days we have touch screen and multiple other interfaces and sound creation tools – MIDI almost seems like a dying art.

The ProtoDeck uses 87 pots, 90 buttons, and 81 RGB LEDs all controlled by 2 PIC 18F4620s. [Julien] says his main goals where to have lots of color and buttons. We think he succeeded.

Neon Lamp And Other Crazy Clocks

January 13, 2010 by Jakob Griffith 22 Comments

Quick quiz, what came before transistors? Why vacuum tubes of course. If this clock doesn’t make you thankful for the luxury of integrated circuits, nothing will.

We had never heard of using Neon Lamps as logic circuits, and they definitely produce a much cooler effect when counting.
[Thanks Philippe]

And finally, we’re just suckers for a good Nixie Clock. The scope clock is also pretty interesting.

194 Transistor Clock Will Blow Your Mind

January 11, 2010 by Jakob Griffith 59 Comments

It’s nice to have tip put on our desks that we think everyone, yes everyone can enjoy. The Transistor Clock is just as its name implies, A clock that doesn’t rely on ICs. 194 Transistors, 400 resistors, 566 diodes, and 87 capacitors are all that makes this clock tick – no programing, and most importantly no Arduino. The clock is offered as a kit, but there is a complete parts list and manual (including debugging help) so anyone can build (and fix) their own. The Transistor Clock might even beat out the VFD Clock and the Word Clock on the ‘pure awesome’ scale, tell us your favorite in the comments.

[Thanks Hoopstar]

Ask A Winner…

We’ve been given the honor of interviewing each team from the Nokia N900 PUSH competition one on one. However, rather than be selfish, we thought it would be fun and informative if the readers got to ask the teams some questions too.

Just post your question in a comment and we will be sure to ask.

Avoid the basics, like “what was your inspiration” – don’t worry, we’ve got those covered. But maybe you have that dieing question of “Haptic Guide: What kind of battery life do you expect with 9 or more motors constantly spinning, surly we wont be wearing Lead Acid around will we?”

Spy On Your Office

January 7, 2010 by Jakob Griffith 30 Comments

[Garagedeveloper] sent us his custom surveillance system, part 1, part 2, and part 3 after needing a way to find out why some cables at work were becoming unplugged (spoiler, the cleaners were messing up the wiring). At the base of the system is a web cam glued to a stepper motor. However, it gets much more in depth with a web front-end that allows the user to stream the feed and control the position of the stepper. We’re not particularly fond of how many different parts the project takes, while it all could be accomplished under C# with ASP.NET and parallel port library instead of including Arduino and excess code, but to each their own and the project turned out a success anyway.

Max/MSP Accelerometer Beat Control

[Ryan] let us know about his Max/MSP Controller. Inside the device is an ADXL 335 accelerometer and 6 push buttons wired to an Arduino. The input data is sent to Max MSP, a sequencer controlling 5 audio tracks, correlating to 5 of the buttons. The 6th button controls delay. What we really liked was how the accelerometer modified the speed of the beat in the X-axis, and the delay intensity with the Y-axis. Whats next? We think gesture recognition might be something fun to try, but [Ryan] is unsure. We’ll keep you up to date.
