Build your Own PCB Exposure Box with Fluorescent Lamps and Countdown System

Introduction Tired of spending hours and hours in wire soldering? Do your circuits look ugly and you are looking for a way to produce professional-like PCBs? Then you had better try photoetching. And the first step to do that is to have the right equipment that is an Automated Exposure Box. Moreover if you like tinkering with microcontrollers, here is the challenge and it's high time you launched the design ...

SX Game System

This page describes a SX28-based color video game system I made during year 2002. Now, beginning of 2007, almost five years after I made the first design I've updated the layout of the PCB and added a version of the PCB that has built-in gamepads and I also have made it possible to buy PCBs, preprogrammed chips, color carrier oscillators and of course complete kits from me in my web shop. Since all games us ...

Building the PIC16F84 based game system

This text describes how to build my PIC16F84 based game system, before you start you should read through the whole text one time. Note that many components are sensitive to too much heat and will get damaged if you heat them too much when soldering. The drawn placement images show components to mount in each step in black and the components mounted in previous steps in gray. When soldering the components on ...

PIC Game System

This page describes a PIC16F84-based video game system I made and first published back in the beginning of 1998. Now, beginning of 2007, nine years later I've updated the layout of the PCB and also updated the source code to also be able to run on a PIC16F628A as Microchip is phasing out the 16F84 and it will soon not be able to be bought. The final new "feature" is that you now also can buy PCBs, preprogra ...

Galvanic Skin Response System

The Galvanic Skin Response (GSR) is a property of the skin to exhibit electrical characteristics. It is also known as Electrodermal Activity (EDA), Electrodermal Response (EDR), Electrodermal Level (EDL), Skin Conductance Activity (SCA), Skin Conductance Response (SCR), and a lot more. The GSR utilizes the principle that skin property varies with the state of sweat glands. The electro-physiological signal i ...

19“ system of enclosures will provide you unexpected space

What enclosure to use for your electronic device and how to sort them when there are several ones on one place? That´s the question reaching almost to beginnings of electronics. No wonder, that since those times a lot of solutions were developed, which were so good, that they´re actual even nowadays. One of such examples is also a known modular 19“ system (482,6 mm wide), where various electronic devices ar ...

System is Down Detector

If you work in a company that has a website, you know how important it is that the website always be up and running. That's why you constantly see "99.99999% reliability!" all over the fancy server hosting sites. A website can't make money if the system is down, so knowing when that happens and reacting quickly is super important. In this Instructable, we will use the LinkIT ONE board to make an alert syste ...
