Jonathan Guberman from the Site 3 coLaboratory in Toronto made the "Automatypewriter," an Arduino-controlled typewriter that acts as both input and output device. He's rigged it to play Zork!
The Automatypewriter is a typewriter that can type by itself:
Each key is attached by fishing line to a solenoid, an electromechanical device that pulls down when electric current is passed through it. The solenoids sit behind and underneath the typewriter in a multi-layer structure. The solenoids are connected to a MOSFET, which allows the lower-power parts of the circuit to control the high-power solenoids.
The MOSFETs are connected in sets of eight to shift registers (integrated circuits that can, amongst other things, expand the number of outputs on a microcontroller). The shift registers are connected to an Arduino, which is connected to a computer via USB. When the computer sends a character to the Arduino, the Arduino chooses which solenoid to fire and sends that information to the shift registers.
If you think that your phone may have been hacked so that your adversaries can watch you through the cameras and listen through the mics, one way to solve the problem is to remove the cameras and microphones, and only use the phone with a headset that you unplug when it’s not in use.
Lured by the internet’s pervasive insistence that it represents a superior, more comfortable typing experience, I recently went back to an old-timey mechanical keyboard. This was a mistake. I am now a hamfisted ASCII jazz disaster.
SpareOne Emergency Phone is a basic cellphone powered by AA batteries. This gives it a relatively short time on a charge, but means that it will have a charge after being stuffed in a drawer or glove box for months. I came across this during my search for the perfect basic phone, but be warned: […]
