TI-Calculator upclocking

calc.jpgBecause you can… here’s a site devoted to overclocking Texas Instruments graphing calculators. The TI-81, TI-82, TI-83, TI-85, TI-86, TI-89, TI-92,a nd TI-92 Plus can be “accelerated”. The 81, 85 and 86 can be accelerated to approximately 2-3x their normal speed, about 18 MHz. The TI-82 and TI-83 can also be accelerated to about 1.5-2x normal speed. They only about double their speed to around 12 MHz. The TI-89 and 92 can be accelerated to around 20 MHz! Thanks Jeremy!

Pay phone looking cell phone mod

Pay phone looking cell phone mod

phone.jpgHere’s a great cell phone mod from bernardroth’s Flickr page. It’s a standard looking payphone headset with metal cable converted to be a headset for a cell phone. I’m going to see where and if you can buy these…ya know, I had heard that many phone companies are removing pay phones, I wonder what they do with them. If I can score a phone handset, I think I could make an app for my Pocket PC phone to only dial phone numbers if I use my old redbox.

I have a hard time exercising unless there’s some type of cool technology involved. jnielsen posted his heart rate and GPS info from the Ironman Arizona triathlon race. “I used my Garim 301 for the entire race and loaded it up to motionbased.com. The GPS has the distance almost dead on. Check it out – but no cracking on my time:) It’s a pretty cool tool – I actually swam a pretty straight line!”. Links to the individual maps and data here.

Tablet PC inking in forums

tablet.jpgMicrosoft’s Channel9 site now allows Tablet PC users to use ink in their forums now. Here’s my post (View image) with some ink from my Tablet. I really like the idea of some type of easy to implement system so more comment systems could allow ink from Tablet PCs, Wacom devices and PDAs. Oh course I’d really like to figure out a way to ink up my photos on Flickr. Update: Here is the first ever comment spam in ink!!

Hacking for GIs

Hacking for GIs

01-call-missed.jpgWow, check out this correspondence figuring out ways to help soldiers in the field diffuse those cell phone detonators. “I was connected via a soldier on Iraq who sent me a picture of the radios they are using to set off the IEDs. Some of them are using FRS radios (Family Radios). The picture I saw was a Motorola TalkAbout 5000 (or something like that). What I did was make a FRS radio connected to a 7 watt external amplifier, and with a BASIC stamp controlling the main function buttons of the radio. It will hop through all 838 possible codes (22 channels, 38 privacy codes) and transmit for 1 second on each channel. Hopefully setting off the bombs before they drive through”.
