2x success!

So I’ve been experimenting with a new feature I’m adding to the Inkscape plugin – basically it allows for assisted double-sided cutting with the laser. You can run the laser at less power (or higher speed) by cutting halfway through one side, flipping over the material, and cutting through the other half. Read the rest of this entry »

Unusual Storage Contest

So here it is, an official announcement for our opening party hacking contest.

There is no pre-reg for this contest, it is more in the fashion of con badgehacking where your entry is presenting your creation at the time of contest closing.

The When:
The contest will cover a 2 day time span. It will commence on Dec 10. The contest building will continue until 11:30pm of Dec 11th. Demos and judging will start immediately after this deadline. Once all entries have been presented by the contestants the results and prize(s) (not yet figured out, but will be announced when they are) will be announced.

The Objective:
As the title states “Ùnusual storage“, meaning to find unorthoox ways to store data. Using traditional sd, eeprom, flash, ram, fram, rom, etc… is so very boring,so lets come up with something different. This can include repurposing an alternate storage medium to store data on ie. using an audio device to store encoded data for a microcontroller. Alternately the storage medium can be some completely asinine inefficient electromechanical device that the host controller can write and read data back off of.

The Rules:
1) The host controller (microcontroller, computer, plc, cyborg) can not store any data within its own devices. The host controller can be any type of device you choose. The host controller must only store data by means of communicating to whatever method of interfacing you choose to communicate with the storage device.
2) Since mechanical devices can get very large the minimum data capacity for the device must be at least 32 bits, less will still be allowed, but please no 1 or 2 bit machines. This rule applies as well if removable storage media is by design, the single removable media should meet this minimum.
Note: this is not a size matters contest so most storage capable will not necessarily score you more points.
3) Volatile data or non Volatile data? Doesn’t really matter.
4) Planning and component gathering (even prep) can be done in the time leading up to this contest but all implementation of the storage system must happen during the contest.
5) Contest entries can be individuals or teams. For sake of putting a number to teams the max is 5 people per team. There is no restriction on external help.
6) No materials or methods will be barred from this competition, I would hate to discourage outrageousness, silliness or otherwise potentially hazardous implementations.
7) Rules can be challenged during contest times and will be governed through feats of strength.

Judging:
- Judging will begin at 11:30pm on December 11th.
- The judging will be done by myself, and some other undetermined individual.
- If your entry is not ready by the time others contestants have finished presenting, your entry will be judged as is. Extra build time may be achieved by means of alcohol delivery to the judges and waiting contestants.

Good Luck!

HOWTO turn a cheap Chinese laser engraver into a pretty good laser cutter

…using only a computer, LinuxCNC, and lots of scrap cardboard.

Every hackerspace needs a laser cutter. Unfortunately, they can be very expensive. Deals like the one Hacklab.to got don’t happen very often. However, there are factories in China turning out laser engravers and selling them on eBay for relatively cheap. We found a local distributor that appears to buy them directly from China, make sure they work, and resell them.

Team Power Fist – Power Racing Series Update

At Maker Faire Detroit (July 31 – August 1 2010), the folks from Pumping Station: One have challenged hackerspaces around the world to participate in the Power Racing Series.

The idea is this: buy a Power Wheels car, mod it to make it MOAR AWSOME, and race it against teams from other hackerspaces. Very simple.

We got ourselves a used Extreme Dune Buggy, and let Jason go at it with the Sawzall.

There was much drilling, lathing, cutting, grinding, and welding.

The organising people announced the Early Bird Challenge a few weeks ago – post a video of your car driving 150 feet, powered by the motor you intend to race with. We didn’t quite get the points, but we did post a video:

Making Games at think|haus

The past few weeks have seen several members working on games at think|haus. Peter designed and made a lasercut chess set, I made some pieces for my travel Settlers of Catan, and JamesQ posted about his 3D chess idea below.

Peter took some really nice pictures of his chess set and posted them on the facebook. His pieces are really nice – very clean and sleek. Each piece is made out of two pieces of acrylic fitted together at 90°. Here’s the thingiverse link.

A few years ago, I bought travel Settlers of Catan so that I could bring it with me on trips. Even the travel set is fairly big though, so I just used the cards and port pieces out of the box, and made my own tiles and cardboard pieces. The cardboard pieces are pretty awkward though, and I’ve never really been pleased with them. Today, I made up a little gcode file to cut out tiny roads, settlements, and cities.

Filling laser etched acrylic: wax vs polymer clay

I made some business card holders for think|haus a few weeks ago. They turned out pretty well, but there was one problem: the etching isn’t really legible from any reasonable distance. I clearly needed to paint/fill the etching with something. I tried two different methods: wax crayon and polymer clay. Photos below the cut. Read the rest of this entry »

3-D Chess pieces for 3-D printers

In response to the Maker bot industries giveaway, I had the idea of making designs for pieces. Not just ordinary chess pieces, but 3 dimensional (Space Chess) pieces. Anyone who has watched ‘Star Trek’ the original series has seen this ‘Three-dimensional chess’.

http://en.wikipedia.org/wiki/Three-dimensional_chess

Unfortunately the contest closes tomorrow at noon, and I just started the project today. I don’t have any skill with using 3-D computer drafting programs, and I don’t think I will be able to learn Google sketchup proficiently in a matter of hours. So, I drew my designs out by hand and posted them here. Read the rest of this entry »

MIDI + Mini Piano

Recently I came across an Electron Echo Mini Piano that my brother and I played with many years ago:

I have no idea who made it or where it came from. The interweb mentions it a few times, but there doesn’t seem to be any information about it.

A moment of inspiration hit, and I decided it would be neat/fun/educational to build it into a sort of glorious MIDI-controlled monophonic electronic tinny-sounding synthesizer.

Peter’s 3D printer on hackaday

Peter and his dad designed and built a 3D printer which is got posted to hackaday: http://hackaday.com/2010/04/19/makerbot-clone/. Cool beans.
