Fresh hacks every day
[Luigi Rizzo] has been working on some hacks for his 3rd generation Kindle. There is already a Python based terminal emulator called AjaxTerm but he wanted a lightweight standalone so he reimplemented the program in C. The 100k binary monitors the keyboard, launching the terminal emulator when it detects a Shift-T sequence. It also uses alternative key mapping to … Read the rest
Wanting to know the outside temperature, [Jamie Maloway] built his own temperature sensor that can be read with a Bluetooth device. Let’s take a tour of the hardware above from right to left. There’s a linear voltage regulator with two filtering caps and a terminal block to attach a 9V battery or other power source. Next there’s an 8 … Read the rest
The Segfault is a balancing transport similar to a Segway, but it uses analog comparators instead of digital circuitry. On board you’ll find no less than twelve LMC6484 op amps. They take signals from the gyroscope and the accelerometer, balance and filter them, then drive the motor h-bridges accordingly.
[Charles], the guy behind the Segfault, is also the one … Read the rest
The use of brainwaves as control parameters for electronic systems is becoming quite widespread. The types of signals that we have access to are still quite primitive compared to what we might aspire to in our cyberpunk fantasies, but they’re a step in the right direction.
A very tempting aspect of accessing brain signals is that it can be used … Read the rest
