Here’s a simple and clever way to build a motorized cart for kids: power it with two 18V cordless drills. The drills friction-drive the cart’s front wheels via two 3/4-inch sanding drums, and you drive and steer the thing by pulling the drills’ triggers, one with each hand. Two fully charged drill batteries will run the cart for about 45 minutes of play time. Thanks Paul! Link.
How to make a war driving box – “It’s very easy, but this is not a step by step HOWTO, only a guide to build your own box. To start, you need a small up and running OpenBSD System on an Intel based System. This Sytem can run on in VMWare or on a older PC System (I use a 500 Mhz Pentuim System with 4 GB HD and 128 MB Ram)” – Thanks Jason! Link.
John writes “Stereo From the Air – I just finished a short tutorial on how to take 3D stereo photographs from on board of an airplane and thought I’d share it with you guys. It’s a fun little project for when you’re pretty much bored out of your skull and stuck in a tiny seat at 33,000 feet.” Link. Here’s another how to I wrote awhile back on making 3D images too. Testing for cosmic rays also passes the time.
Here’s more about the DIY cell phone project – ” Surj Patel is building his own cell phone, bit by soldered bit. It’s not easy. It starts with parts that cost around $400. Then Patel and his partner, Deva Seetharam, have to write code to run on the tiny Linux-based computer that he’s hoping will serve as the brains of his new phone. So why bother? After all, it’s not like cell phones are hard to find or terribly expensive.” [via] Link.
Rael had a great idea, use these PocketMods for Make for shopping lists and instructions for a project. “The PocketMod is a new way to keep yourself organized. Lets face it, PDAs are too expensive and cumbersome, and organizers are bulky and hard to carry around. Nothing beats a folded up piece of paper. That is until now. With the PocketMod, you can carry around the days notes, keep them organized in any way you wish, then easily transfer the notes to your PDA, spreadsheet, or planner.” Link.
Edward writes “The Boy Mechanic: Volume 1 by Popular Mechanics. Offered thru Project Gutenberg. 700 Things for Boys to Do. This book was my first intro to making things when I was a kid. Published in 1913. The PDF version is richly illustrated.” Link.
Chris sent this how-to in from Grynx contributor Dan “This box will house my proprietary Wi-Lan HP45-24 radio unit and set as a client, a 2.4ghz 500mw HyperLink Amplifier connected to a Linksys WRT54G with a third party firmware and set as an access point, the Wi-Lan HP45-24 radio will be the main link back to my base radio. The whole idea of this enclosure is to be as “modular” as possible, i.e. if the PSU blows-up I can simply remove the PSU and replace it, OR if I need to relocate the whole box, I can simply unscrew all the antenna and take it away with me.” Link.
