Egg-Bot + PVC Pipe

Drawing on PVC Pipe

In looking around the workshop for something to make an egg stand out of (for better photos) I came across some scrap PVC pipe from when I constructed a backdrop stand, and realized that the pipe was round, and white, and might actually work in the Egg-Bot… you know, instead of an egg.

I did a quick test, and it ended up working. The first plot depended on a lot of curves, and since I didn’t bother to spend much time doing a proper set-up (you know, finding the center, adjusting the headstock, tailstock, and distal arm) it wasn’t spectacular, but it did work.

Plotting on Pipes

Since the pipe is not a sphere, I did make some adjustments to the SVG file, making sure it wasn’t too tall so the pen wouldn’t angle itself too much. After drawing on the first pipe I ended up wrapping a piece of paper around the second one so I could keep testing without running out of pipes. I also ended up sticking corks into the end of the PVC instead of using cardboard shims. This probably helped a bit with the centering.

I’d like to try to get some thicker PVC, closer to the width of an egg, and keep experimenting with this… it’s a nice way of testing without running through a dozen eggs in an evening.

Makerspace/Hackerspace Membership Costs

Hackerspaces

I wanted to do a bit of research on the cost of being a member of a hackerspace or makerspace (and by cost I mean, monthly membership fees.)

I started at hackerspaces.org and just looked at spaces in the United States.

Since the information is coming from a wiki, we can’t be sure it’s completely accurate, but I think it’s a good gauge of fees nonetheless.

Name Location Members Per Month
ATX Hackerspace Austin, Texas 41 25 to $75
Ace Monster Toys Emeryville, California 80 $80
Alpha One Labs New York, New York 37 $40
Arch Reactor Saint Louis, Missouri 23 $10 to $30
The Baltimore Node Baltimore, Maryland 18 $50
Bitsmasher Santa Cruz, California 33 $50 to $100
BrainSilo Portland, Oregon 20 $40
Bucketworks Milwaukee, Wisconsin 50 $75
Collexion Lexington, Kentucky 25 $5 to $60
Columbus Idea Foundry Columbus, Ohio 50 $25
Cowtown Computer Congress Kansas City, Missouri 30 $30
Crash Space Los Angeles, California 30 $37 to $108
DHMN Appleton, Wisconsin 23 ~
Dallas Makerspace Dallas, Texas 50 $50
Dayton Diode Dayton, Ohio 8 $50
HacDC Washington D.C. 42 $50
HackPittsburgh Pittsburgh, Pennsylvania 25 $30
HackerDojo Mountain View, California 183 $100
Hackerspace Charlotte Charlotte, North Carolina 30 $40
HeatSync Labs Chandler, Arizona 17 $50 to $75
Hive 76 Philadelphia, Pennsylvania 15 $15 to $100
I3 Detroit Detroit, Michigan 32 $39 to $89
Jigsaw Renaissance Seattle, Washington 50 $15 to $200
Midsouth Makers Memphis, Tennessee 20 $25 to $75
Milwaukee Makerspace Milwaukee, Wisconsin 17 $80
NYC Resistor New York, New York 27 $75 to $115
New Work City New York, New York 75 $300
Noisebridge San Francisco, California 80 $40 to $80
Pumping Station: One Chicago, Illinois 50 $30 to $50
Sector67 Madison, Wisconsin 21 $50 to $100
Twin Cities Maker Minneapolis, Minnesota 35 $50
Zero1 Nation Colorado Springs, Colorado 14 $13.37 to $35

I tried to include some of the spaces I was already familiar with, or ones in larger cities, which I thought would provide some good contrast.

I also included the number of members in thinking that the number of people involved would affect the cost per member per month.

Some of these are non-profit organizations, while others are not. Some have student or “starving hacker” rates, and most of them seem to have open times/events where anyone can come. Some allow guests (and some suggest guests make a small donation to the space) and many have tiered membership levels.

I talked to Bre at NYC Resistor and asked about their pricing, which says that if you teach classes your membership fee is $75 per month, and if you don’t teach classes, it’s $115. I had assumed this was to reward people who teach by giving them a discounted rate, but he suggested it was more along the lines of punishing those who are slackers and don’t do any teaching. Either way, it’s a neat idea. :)

Obviously the amenities or “what you get” for your membership will vary. Some of the spaces are meant for you to have a permanent desk, provide good Internet pipes, meeting rooms, and function as your everyday office, while other are more like workshops, with tools you may not have access to anywhere else. Prices obviously vary depending on geography as well. Of course you’d expect that In a bigger city you’d probably find more members, and that the rent would be much higher. In a place like Appleton, Wisconsin, it may prove hard to get enough people interested to build momentum to secure a space. (It took the Milwaukee Makerspace folks about a year to get their space.)

If I’ve got anything wrong, or your space was mentioned incorrectly above, please let me know… This was really just a quick look at the monthly membership fees of a bunch of different spaces.

Disclaimer: I am involved with Bucketworks, and I am friends with the folks in DHMN and Milwaukee Makerspace, and have a loose affiliation with Sector67, Jigsaw Renaissance, and Pumping Station: One. (The last three being members of the Space Federation.)

Kickstarter: Gameduino

Gameduino

The most interesting Kickstarter project I’ve come across recently has to be Gameduino:

Gameduino connects your Arduino to a VGA monitor and speakers, so anyone who can write an Arduino sketch can create video games. It’s packed full of 8-bit game goodness: hundreds of sprites, smooth scrolling, multi-channel stereo sound.

James Bowman was hoping to raise $3,333 to do a manufacturing run of the Gameduino, but with the deadline tomorrow, it’s now at $35,253 raised. Amazing!

I also think the pledge levels were chosen wisely…

$3 or more gets you a zip file containing all the raw video and audio.

$53 or more gets you a Gameduino from the production run, assembled and tested.

$113 or more gets you a Gameduino, a printed reference poster, a joystick, and an Arduino Uno, preloaded with the Asteroids game.

$263 or more gets you all of the above, plus your 64-byte message burned into an easter-egg section of every Gameduino’s boot ROM. (8 of these were available.)

$433 or more gets you all of the above, plus the Arduino preloaded with a game of your devising. Just supply the graphics, describe gameplay, and I’ll have a weekend hackathon to put it on the Gameduino. (4 of these available.)

Gameduino

At the base, you can toss $3 towards the effort, just to show your support and help make things happen. For $53 you get an actual Gameduino from the production run. One would hope that they do more production runs, based on the money raised, I’d say that’s a sure bet. But will it cost more or less than $53 next time? If you don’t want to risk it costing more, or you just want to be one of the first to have one, this is a great option.

And for the people who really want to support the project, there were 12 higher-end support options, 4 of which get you custom game development. (All of them sold out.)

Also worth noting: The Gameduino is open-source hardware (BSD license) and all its code is GPL licensed. Nice! This means that once it’s created, others should be able to build and sell them as well. I’d expect kits to appear in the future.

Check out the Gameduino project page for a sweet video showing it’s capabilities, and if you want one, hurry up and pledge today!
