TD-USB-02 interface with touchpad sensor board and WinAmp interface. This is an example USB project showing how to interface a touchpad sensor (the AD7142ACPZ) with a standard XP/Vista computer. The TD-USB-02 board with a PIC18F2550 communicates with: the PC: USB 2.0 through a mini-B connector. the touchpad sensor board: SPI over 8-wire flatcable. PC WinAmp […]

Graphene has become an all-purpose wonder material, spurring armies of researchers to explore new possibilities for this two-dimensional lattice of pure carbon. But new research at MIT has found additional potential for the material by uncovering unexpected features that show up under some extreme conditions — features that could render graphene suitable for exotic uses […]

It’s amazing what you can do with just a few components: a load cell, a high gain analog-to-digtal converter and a NodeMCU module. You can for instance measure the water consumption of your dear plants. If you combine the previous mentioned components with a OLED display you can even visualize the current water level in […]

Sunlight simulation and light therapy light boxes are commonly used as light therapy for treatment of Seasonal Affective Disorder (SAD).  My mom has SAD and after seeing her wimpy light box I thought there had to be something better out there, after some research I was really surprised at the underwhelming sunlight simulator light therapy options on […]

CHANDLER, Ariz., Nov. 5, 2007 – Microchip Technology today announced the new Microchip PIC32 family of MIPS 32-bit microcontrollers (MCUs). The Microchip PIC32 is based upon the MIPS32 M4K Core, a high performance core with 32 core registers that are each 32-bits. Microchip has extended the functionality of the M4K core with some unique proprietary […]

The solution is an embedded module. Swedish company Embedded Artists will help you in tit by their top-class modules with NXP processors. Embedded modules are still more used in many products, where so far a classic microcontroller was sufficient. As requirements for functionality of devices are increasing, including audio/video output, network- and USB connectivity, as […]

Hello all and welcome to my second Christmas related project. Have you ever received a really boring Christmas card? Have you ever sat there and thought to yourself “If only there were a little video game on this card that I could play…” Well ponder no more because that card is here! This instructable will […]

Tunnel diodes are a bit rare these days, but still have uses in special applications including extremely high frequency oscillators, etc. They were commonly used in microwave circuits, oscilloscope trigger circuits, and other applications. This video reviews the basics of tunnel diodes, including the basic properties and simple applications. I refer to these as the […]

This is my first instructable…. ever. So here it goes. I own a Kaossilator 2 (KO2). It’s fun little phrase synthesizer and simple looper. But it has this awkward issue with mic button. When you want to record something from microphone you have to hold down two buttons simultaneously. First the mic button to enable […]

Some time ago I was developing a medical instrument which required histogramming, which got me in the mood to retake my own PIC MCA project(http://home.comcast.net/~prutchi/index_files/scint.htm ). I used the variable RAM in the microcontroller (16F877), so I limited the number of channels to 95 and let the histogram run until some channel reaches 240 counts (the […]
