Powersupply and CRT deflection and microcontroller test circuit. I was lucky to purcase two used but working DG7 tubes and a transformator cheap, one from Mullard and one from Phillips. Other CRT Cathode Ray Tube types can be used, you can even rip one from an old and maybe dead oscilloscope, then you also get […]

High-Level Design The project can be logical separated into two different components: the glove and the car. The glove is the main way the user will interact with the car. Several fingers on the glove are outfitted with flex sensors to capture events when the user curls or uncurls figers. There are a combination of

Following on from the LED flasher circuit, we can reduce the delay in the loop to 10uS (10 microseconds) and produce a 100Khz square wave. Given a 4 Mhz PIC 16C84, the program below will generate a 100Khz square wave on PORTA bit 0 (i.e. pin 17). This little program is useful for testing oscilloscopes

description This is my electronic codelock to use with an outdoor gate. The lock itself is implemented in software. It operates a relay (for example to open a door) for a few seconds if someone enters the valid code. The secret code can be changed any time after entering the current code. Note that in

Open electrical doors with your secret code only! Here are the technical specifications: Up to two keypads may be connected to drive both relay outputs. Professional, outdoor or other keypads may be used. Relay outputs are configurable: output voltage +6 to +24VDC (from power input) or simple switch emulation. The small LCD is optional, and

Introduction For our final project, we built a whistle controlled light switch. We were motivated by the daily struggle of getting out of bed to turn on/off the light. You can attach our final product on any light switch that can be commonly found in U.S. households. Once a correct sequence of whistle frequencies is

Programming microcontrollers isn’t hard. Building a programmer makes a great first electronics project. The goal of this instructable is to explain the simple ‘in circuit serial programming’ method used with Microchip PICs. Step 1: Why ICSP? Programming a big DIP (through hole) chip is easy. Pop it into a socketed programmer, burn, and return to

You can add this circuit to all sorts of projects that require on-off control. Our design allows up to 4 touch sensors using a PIC12F629. The output of each touch sensor is active LOW and this can be connected to an additional circuit to control a LED, motor or relay etc. The photo of the

This project will improve the output of your solar panel by about 40%. It uses a motor and gearbox from a 3.6v power screwdriver, however a number of different voltage motors can be used. The project has its own 6v power-supply made from five 1.2v NiCad cells and a charging circuit using a separate 3v

We have seen many projects using a set of LEDs to produce words “in the air,” but none have the clever feature we have included. Most of the projects are “shaken in the air” and produce messages that are “all over the place.” But if the words are jumping they are difficult to read. Our
