The Apple II personal computer, which stylized as Apple ][, is an 8-bit home computer and one of the first highly successful mass-produced microcomputer products. It was designed primarily by Steve Wozniak and developed with Steve Jobs. Apple ][ was introduced in 1977 at the West Coast Computer Faire by Jobs and was sold several […]

Description In under 1kB, this project uses a tiny, custom-made pixel font to write a message to a display. It receives messages from the UART and writes them to the display. The font was created using my homemade small font designer (see external links). It includes all letters (uppercase/lowercase), numbers, and most punctuation. The font
Story The Tiny TS is a credit card sized (100x65mm) fully open-sourced synthesizer with a 1-octave capacitive touch keyboard. It has Audio/CV/Gate outputs and 6 synth parameter dials. The CV’s output 1V/oct and Gate from the keyboard. With the version 1.1 firmware it now also handles CV/Gate input from a sequencer. The synthesizer parameter knobs

Battery technologies of all chemistry are experiencing revolutionary changes nowadays. Nanotechnology is leading this revolution by yielding new battery technologies including but not limited to Tiny Supercapacitors and Li-ion batteries that never explode at any condition. But, it’s bothersome to make different chargers for different types of batteries. So, Microchip solved this problem by introducing

Background and motivation It should come as no surprise that I really really want a Tesla. Or really any Electric Vehicle for that matter. The only problem at the moment is that my daily commute takes me 20 minutes on foot each way, so I really can’t justify buying a car that will spend most of

Making an electronic dice is very popular among hobbyists and there are already lots of ready-made projects on the internet about this topic. Tim at Hackaday.io designed an electronic dice project for “1KB Limit” competition. But why another dice project while the internet is already crowded with similar things? Well, it’s not the subject of this

Researchers at the École Polytechnique Fédérale de Lausanne and the Centre Suisse d’Electronique et de Microtechnique have invented a new device to store solar power while the sun’s not shining by converting it into Hydrogen. Although many current methods use the same approach to store energy, but this device rivals them in stability, efficiency and

Researchers at the University of Central Florida have been looking for alternatives for lithium rechargeable batteries which are largely used in every device. Using two-dimensional (2D) transition-metal dichalcogenides (TMDs) capacitive materials, they are building a new supercapacitor that overcomes the performance of conventional lithium battery and replaces its efficiently. Transition metal dichalcogenide monolayers (TMDs) are

The Bluetooth Special Interest Group (SIG) has officially launched the core specifications of the new version of Bluetooth: Bluetooth 5. These specifications include longer range, faster speed, and larger broadcast message capacity, as well as improved interoperability and coexistence with other wireless technologies than recent Bluetooth versions, making it possible to advance IoT applications and

Currently I’m trying to make a working version of a radioactivity detector that uses semiconductor as a sensor. It’s a different approach than Geiger-Muller detectors or ionization chambers, more complicated, but also much more interesting. While Geiger-Muller counters can only provide information about the amount of particles in a period of time, semiconductor detectors can
