Hackerspace Happenings: DIY Geiger Counters at Tokyo Hackerspace

Are you a hackerspace member with an event you’d like to publicize? Send it to johnb@makezine.com or tweet me at @johnbaichtal and I’ll post it. Also feel free to subscribe to my hackerspaces Twitter list. Hackerspace Happenings run weekly(ish) Tuesdays, and the next one will come out August 13th.



DIY Geiger-Mueller Counter Workshop at Tokyo Hackerspace

Tokyo Hackerspace is holding a class on building your own Geiger counter:

The 2nd-in-a-row class will be held at THS house, as usual on August 22nd, 19:30-22:30.

The kit consist of 3 parts: motherboard (Freakduino), daugtherboard (NetRAD shield) and radiation sensor (SBM-20 GM tube). If you have any of these, you can use yours, but we’ll have to make sure they are similar enough.
Once assembled, tuned and tested you just connect it to a DHCP-enabled LAN connected to the Internet and it will upload data to Pachube data aggregation service.

Fees are ¥500 for members and ¥1,500 for nonmembers, plus you can buy any of the three components if you don’t have them already.



Women’s Night at the Hack Factory in Minneapolis, MN

Female Hack Factory denizens and visitors are invited to show up for Open Hack on the 30th of August, with meetups planned for the last Tuesday of every month. Doors at 6, festivities begin at 7. If you’d like to participate, just show up or tweet @bones_n_stones.



From Tinkering to Commercialization

Louisville, KY’s LVL1 is co-sponsoring a talk on commercializing maker projects:

LVL1, KSTC, the Louisville Metro Inventors Council and Enterprise Corp are joining forces like a techno-entrepreneurial Justice League to teach makers how to make money, and maybe make Louisville more awesome in the process. From Tinkering to Commercialization – A “How To” Guide is a workshop set up for hardware hackers and inventors that teaches the ins and outs of bootstrapping and commercializing your designs for fun and profit.

Attendees will be introduced to the basics of how to take one’s projects from the garage to commercialization. Speakers will include Tendai Charasika of GLI’s EnterpriseCorp, Alex Frommeyer of Louisville Metro Inventors Council, and Ben Jennings of the Kentucky Science & Technology Corporation (KSTC). This will be a presentation and Q&A, with an emphasis on prototype manufacturing.

Space Shuttle Cake with Ice Cream Tank, Chocolate/Caramel Boosters

Was Googling for interesting stuff made with PVC pipe today and happened upon this impressive theme cake from Craig T. Fifer of Alexandria, Virginia:

The Orbiter is made from brownie covered in fondant; the orange External Tank is made from PVC pipe and holds ice cream; the white Solid Rocket Boosters are made from PVC pipe and hold chocolate syrup and caramel sauce, respectively; and the brownie base is topped with whipped cream steam with color mist and sprinkles.

Challenge: How To Make 1-inch Wooden Cubes?

I want to make a Soma Cube (a kind of puzzle, which you can read about here) for my kids (and myself).

But I’m having a hard time making accurate wooden cubes from 1-inch x 1-inch wood sticks. I tried using a miter saw but there is too much error. I know it is possible to buy inexpensive wood cubes, but I am interested in finding out how people can make them at home, especially with hand tools.

 

How-To: Corpse From Plastic Skeleton

Rachel @ CRAFT writes:

We’re reaching that time to start planning for cool Halloween decorations, and this video tutorial from Propnomicon could take your spooky decor to a whole new level. He shares how to take a simple plastic skeleton and transform it into a freakishly realistic corpse with just a few simple supplies and less than an hour of your time. Forget cutesy pumpkins on your porch, this corpse will simultaneously terrify and fascinate your trick-or-treaters and make yours the most popular house on the block.

How-To: Demonic Garden Gnomes

Cool original content over at Hack a Day, featuring guest author Jack Buffington. Jack hybridizes a common, less-conspicuously-evil lawn gnome with a solar garden lamp to create a full-bore, out-and-out-unholy abomination of a lawn gnome with eyes that glow in the night. I’m going to make a bunch and put them in the flower beds around my house, peering in the windows. Especially outside the baby’s room.

Tokyo Hackerspace’s Geiger Counter Project Continues to Evolve

This March, Tokyo Hackerspace was hooking Geiger counters up to the Internet to get accurate radiation readings and stream the data for all to see. Since then, they haven’t been resting on their laurels, teaming up with Safecast and developing a NetRad shield that fits on the Freakduino wireless microcontroller board. THS member Akiba gave us an update:

We joined up with Safecast (RDTN at the time) and since then, almost all the core members of Safecast Japan are now Tokyo Hackerspace members. The office is also inside Tokyo Hackerspace. We started up a joint project with Keio University to create a radiation sensor network across Japan. The goal is 300 nodes by the end of the year and 1000 nodes by next year. The NetRAD boards were modified to accommodate this and we added WiFi so that it would make deployment and cabling easier. All the data is open and since then, Yahoo Japan started publishing their radiation map using our feeds.

We also are using special versions of our Geiger counters mounted on cars to geotag Geiger data and create maps.

 

World Maker Faire NY 2010 makers’ DIY essentials in IEEE Spectrum

O’Reilly Radar contributing editor James Turner has a great round-up of essential maker tools in the current issue of IEEE Spectrum:

What are the tools every hands-on projecteer needs? To answer that question, we went right to DIYers themselves, specifically the exhibitors at last fall’s World Maker Faire NY event.

One tool everyone agreed on is a Multimeter. It’s surprising how much information you can glean from a simple resistance reading or by checking out the voltage drop across a series of LEDs…

DIY Essentials: Does your do-it-yourself workbench have everything you need?

(Great timing on James’ article! World Maker Faire New York 2011 is one month away!)

 

Android Powered Robot Tank

The smartphones NASA uses on missions to conduct experiments are the same smartphones that can be used to control your next hobby robotics project. Android robotics enthusiast, Tamlyn, used a IOIO board and a reclaimed RC tank chassis to create this Android powered robot tank. [via electricpig]

 

LED Light Bulb Teardown

Ever curious to see what’s inside those everyday objects we take for granted, EDN’s Margery Conner tears apart the AmbientLED light bulb from Philips to see what makes the oddly yellow bulb emit a white light when lit. [via YC]
