1. BACKGROUNDCosmic rays are particles and nuclei which bombard the earth from all directions [1]. The Greisen-Zatsepin-Kuzmin (GZK) limit is a theoretical upper limit on the energy of cosmic rays from distant sources of 5*10^19 eV. The limit is set...
System diagram Internal operation of the spectrum analyzer The analyzer has the classic structure with a local oscillator, mixer and IF system. The Si4012 is used as local oscillator, it generates up to 960 MHz and has a two-wire control interface. The...
For now, CalcHack adds the following hardware:- Complete hardware control over calculator allowing it to be undetectable- Cortex M4 main CPU with Cortex M3 coprocessor- microphone- speaker- 9 axis sensor system (gyro, accelerometer, compass)- 2.4gHz...
Screvle is the result of years of software and hardware development. The goal is an easy-to-use embedded system development platform that allows to quickly make new embedded tools and applications. Using the rich feature-set of the Screvle platform you...
Version 2 (in the works) also uses a Teensy 3.1 and a HC-05 Bluetooth module.Features: - Embeded code written in Arduino IDE - Android app written with Processing in Android mode - W25Q128FV 128Mb SPI flash memory - up to 4 "spokes" of WS2811 LEDs are...
A voice activated, web enabled active project repository that reduces the friction of documenting a build. It is a device that is left in or near your project as you build. You use voice commands to interact, taking audio notes or taking pictures with...
An old school friend’s son, Bennett, is losing his eyesight. Ben was born at 23 weeks gestation, which is way too early, in case you were wondering. Just to get to the age of nine he and his family have overcome a great number of challenges. Most likely...
As i managed to do most of the work before starting the project on here there's not much to update, but initial tests with an Acorn Electron seemed to work ok. I have found the wave files need to be as close to a square wave as possible (i usually...

PCB layout done in Altium.Prototype PCB made by hackvana.com (great job Mitch!)Mostly OK! power supplies all good, SD card interface works well, SPI to ENC28J60 worked well (DHCP/UDP), UART i/o and GPIO all going as required.Problems: JTAG pins back...
A web browser for the Arduino platform is a silly idea. The PIP Arduino browser is an on-going project. Parsing HTML code cleanly is not easy. Doing it in under 2KB of RAM is less so. When the code is cleaned up bit more (soon), it will be available...
The code can be purchased from the ISSAbove.com web site as a downloadable SD card image that you write to your own SD or MicroSD card. Setup is accomplished using a simple browser based admin system where the user selects their location from a google...
ICheap to build, wearable or at the very least very pocketable battery powered Lo-Fi (8 Khz) Digital voice recorder that Thomas Edison himself would approve of.I'm very confident that anyone with a Atmega 328 Based board running a Arduino compatable...
