make your own wearable LED display using pic-microcontroller
Posted on: 03 Jul 2016
jump to a section:supplies about LED arrays design construction customizing/programming washing and wearing troubleshooting and FAQ **NOTE** As of Fall 2007, skip the ugly microcontroller programming (don’t buy the STK500 or the AVR chip)… Get a LilyPad Arduino instead. It’s much easier to sew and to program! See my LilyPad Arduino tutorial for help on […]
Oscilloscope clock
Posted on: 03 Jul 2016
An eight pin Microchip PIC microcontroller is programmed to operate from a 32768 Hz watch crystal and output waveforms which, when displayed on an oscilloscope, show the time in HH:MM:SS format. The screen capture shows winscope showing 12:46: … Step 1: Design the character set On an oscilloscope screen, vertical axis (up and down) corresponds […]
Fully reprogrammable optical chip developed by Bristol University team
Posted on: 03 Jul 2016
Researchers from the University of Bristol and NTT in Japan have developed an optical chip that can process photons in an infinite number of ways. According to the team, the fully reprogrammable chip marks a ‘new era of research’ for scientists and engineers at the cutting edge of quantum technologies. Dr Anthony Laing, who led […]

Wireless Sensor Motor Control using PIC18LF4520
Posted on: 02 Jul 2016
Last week we took a look at how you can wirelessly connect together two unrealted microcontrollers; an Arduino UNO and a PIC. The week before that we showed you how to build Motor Control via Distance Sensing. This week, let’s combine the two project together to make a wireless IR proximity sensor that can control […]
Analog Ultrasound Range Finder
Posted on: 02 Jul 2016
When I started my career in control systems I was fascinated with the many different ways that machines could be interfaced to the environment they operated in. Limit switches (electrical and optical), encoders, resolvers, strain gauges, thermocouples… the control system engineer had a long list of sensors to choose from. And the list has grown […]
2-Channel IR Relay Controller for PIC10F200
Posted on: 01 Jul 2016
Description This project is a 2 channel infrared (IR) remote controlled relay driver with power saving. It works with 12-bit SIRC IR signals as used by Sony remote controls. The controller also features a power save feature which reduces the relay holding voltage to 50% of the relays nominal operating voltage once the relay has […]
Gas Cooker & Water Purifier Using Free Energy
Posted on: 01 Jul 2016
I originally wrote this for my final year project in 2005. I won’t provide a parts list as certain technology has moved on such as the ease of Arduino for the electronics and solar cells are a lot better and readily available now. Also I was a student at the time and so my budget […]
UT204 is able to measure DC current and also True RMS
Posted on: 01 Jul 2016
UT204 from company UNI-Trend is a near relative to the UT203. multimeter. Already UT203 provides a lot of user comfort and a very pleasant feature – measuring of a DC current without interrupting a measured circuit. However UT204 is different from its “weaker” brother in one essential thing – it enable measuring of a true […]
Momentary switch controls mains with latch-on and remote shutdown
Posted on: 30 Jun 2016
The purpose of this Design Idea was to improve reliability, add new features, and replace a latching power switch with a momentary one. The features are: The switch has foolproof protection against too frequent switching, which can be harmful for many applications. It can handle significant power because manual control and switching are separated. If […]
