HOW TO – Build an Electrostatic Motor
Here’s how to make a very cool motor from a disposable plastic drinking cup, aluminium foil, glue-stick, bamboo or dowel, wire and a non-conducting base, such as a plastic plate or a wooden board. Kiteman writes – “Normal motors are driven by electromagnetic forces. This motor needs no batteries, mains supply or solar cells. Electrostatic motors are turned by the kind of electricity generated by wearing nylon clothes in a modern office. Think of it as gigantic nano-technology as well, because this is how the microscopic motors of nanobots work.” Link.
Pretty unfortunate. I suspect we’ll see a hack to work around this soon – “So you just bought a Windows Mobile Treo with EV-DO service and you want to use it as a modem for your laptop? Forget it. Verizon Wireless says you must buy a second 3G subscription and they have the technology to back it up. Specifically, while the device, which has well-reviewed, comes with Bluetooth, Verizon has disabled the Bluetooth dial-up networking capability that would enable the Treo 700w to act as a modem for laptops.”
Good round of motherboard upgrading tips on Extremetech – “…motherboard upgrades can be either difficult or straightforward. It all depends on how you approach it and how you prepare. We’ve upgraded motherboards quite often over the years, so we’ve learned a few lessons along the way. We’d like to share our knowledge, so that when you tackle this, you encounter minimal hassles. Our pain over the years is now your gain.” Thanks Star!
Hannes writes in with a great product at Macworld for going paperless – “The Fujitsu ScanSnap Mac – It was announced at Apple Expo last September in Paris and I bought one instantly. Within a few afternoons I scanned a few thousand pages (and threw away more than 10000 pages of paper!) and now I have no more paper at home (only books!). All of these pages are now saved as PDF and alltogether use around 800MB, so they easily fit on a 1GB SDcard, that I can view on my MDApro.”
Not a bad deal for $49. “MIDISpeak Module – Version 2, The Talking Toy MIDI RetrofitAdds a standard MIDI IN port to your Speak & Spell, Speak & Read, or Speak & Math. Non-English versions also supported. Trigger thousands of sounds–words, word fragments, garbled speech, percussion and bizarre sound effects.”
This look really fun, and really scary, but it’s NERF, so it’s probably OK. “The FAR is a magazine fed spring powered rifle capable of firing Nerf darts in rapid succession. It uses a fast-action bolt system. This means that all that needs to be done to cycle the weapon is to rack the bolt back and release. The rifle is fed by a bottom feed detachable magazine that holds 5 rounds. The design of the FAR permits it to be fully disassembled and all components accessed for repair or replacement. Only a philips head screwdriver and a pair of hands are required for field stripping.” [
