In the Maker Shed: Vacuum Tube Radio Kit
The Vacuum Tube Radio Kit kit allows you to put together a real, functional, vacuum-tube radio! And it looks so sharp, once you’ve built it you’re going to want to show it off. Includes instructions in Japanese, but we’ve got English instructions right here under the “How To” tab. MAKE is proud to be the exclusive distributor in North America for these brilliant kits, part of Gakken’s Sophisticated Science Kit for Adults series.
In the Makers Market: Police tape scarf
Our own indescribably awesome Becky Stern makes these sweet black-and-yellow crime scene tape scarves to order:
This machine-knitted scarf looks like police tape and features the text “Police line do not cross” along the length. It’s double sided! Designed by my close friend Michelle Kempner, the hand-knit pattern and scarf was featured in CRAFT, Volume 04. Knit from high-quality yellow and black 100% cotton yarn, the scarf measures 7 feet long and 3.5 inches wide. Your scarf is made to order, so please allow six weeks for me to lovingly make yours on my computerized knitting machine. The photo of me above was taken by Matt Mechtley.
You may recall Becky’s Atomic Emission Spectrum scarves from a few weeks back. They’re both available now in Becky’s Makers Market store.

Math Monday: Math-play with your food

Cool glass bottle lamp
I dig this Cadillac Dystopic Lamp by Instructables user PopEye42, which does something I’ve been meaning to try myself for a long time–using cut 1L Perrier bottles as lampshades. I also like that the dimmer switch has a hose valve handle on it.
NES cartridge harmonicas
Ebay seller nes_harmonica is offering three of these old Nintendo cartridges that have been modded to contain working harmonicas. Why the heck would you do that? Turns out it’s kind of a retro in-joke for NES enthusiasts. OhGizmo’s Andrew Liszewski explains:
If you grew up in the 80’s and played video games, at one point in your childhood you had to blow on an NES cart, or inside the console itself, to get it to recognize a game. In fact I never even had an NES, but I can still remember having to do it on a friend’s system. At this point it’s almost become cliche to bring it up whenever the conversation turns to classic video games, but that didn’t stop one clever modder from attempting to turn a profit on Nintendo’s folly.
Right now Super Mario 3, Dick Tracy, and Legend of Zelda models are available. [via Geekologie]
Steampunk coilgun pistol
Nick Thatcher’s compact coilgun uses a coil of copper wire along the barrel to launch its projectile. It’s powered by 15 photoflash capacitors juiced up by 2 AAAs. Of course the power of this gun is very much in question, the super dark video on the site doesn’t show a whole lot. It appears, however, […]
