Fresh hacks every day
You can leave the TI graphing calculator at home thanks to this web-based TI-83 and TI-84 emulator. As with pretty much all emulators, this depends on a ROM image from the actual hardware to work. But if you have one of the supported calculators (TI-83+, TI-83+ SE, TI-84+, or TI-84+SE) you can dump the image yourself and this should work like a charm. [Christopher Mitchell] calls the project … [Read more...]
It's great to see Linux running on a device in a way that was never intended. [tangrs] has successfully run a Linux kernel on the ARM based Nspire CAS CX graphing calculator. He's developed an in-place bootloader that allows a kernel to be loaded from within the stock Nspire OS. It also allows for peeking and poking at memory for debugging. [tangrs] also managed to get USB host mode working … [Read more...]
[Christopher] at Cemetech, ever frequent HaD feature for his hacked up graphing calculators, made it to the NYC Maker Faire. He already posted on his blog he was making the trip up to Maker Faire, but we were lucky enough to catch up with him. Two things: the name of his blog isn't 'cement tech', but 'chem tech.' Apparently he hates it when it's mispronounced. Secondly, he's been turning … [Read more...]
What happens when you combine a TI-84+ graphing calculator with an added bluetooth module, a 1 Watt Alfa wifi dongle, and a Parrot Wifi Quadcopter? You get a long range quadcopter that's controlled from the TI-84+ directional pad. This TI-84+ looks like a standard issue school calculator, but [Owen] added an ATTiny13 microcontroller and a bluetooth module which sniffs the I/O port of the … [Read more...]
Global CALCnet lets you connect your TI graphic calculator to the Internet and use your favorite services like instant messaging and Internet relay chat. It also provides the option of worldwide multiplayer functionality for games ported to the device such as Scorched Earth and Tetris. We looked in on [Christopher Mitchell's] CALCnet in December when it was being used to create local area networks … [Read more...]
[Greg] was feeling nostalgic about the game RACE for to TI-83 graphing calculator. In the game, your car is stationary with controls to move the scrolling maze from side to side in order to avoid a crash. He set out to build a physical version of the game with a don't-touch-the-side concept that reminds us of Operation. The game board is a wire frame constructed from paperclips then attached to … [Read more...]
Add lights to your graphing calculator. Do it now. [Sil3ntP8nd8] added some, and seems to have done a decent job. They are spread around the back, supplying a nice even light on, well, on whatever is under your calculator. It may be difficult to see too much detail though on account of the water marks. You have to protect your intellectual property though. This almost compares to the DS LED … [Read more...]
