How To Make Circuits On A Stripboard

A stripboard is a circuit board with holes and printed strips of metal.

Stripboard circuit with components

These boards are a good way of connecting simple to medium complicated circuits. I highly recommend using stripboards in the beginning. They give you a lot of control of your connections and it’s relatively easy to fix errors.

Though when your circuit gets too many connections, it can be a real hassle keeping control of all the connections.

Digital Stopwatch Circuit

This digital stopwatch circuit is a circuit I built for testing some 7-segment displays. It consists of four displays that I control using a microcontroller. The microcontroller counts and makes sure the correct LED segments on each display is lit up.

Check out the video below to see how I built it.

3 Ways To Build Circuits

If you want to make electronics you need to build circuits. Here are three methods you can use to build any kind of circuit.

Build Circuits With A Breadboard

Breadboard with 7-segment displays

Building circuits using a breadboard is super easy and quick.

A breadboard is a board for prototyping. It has holes where you can stick component leads or wires into. Some of the holes are connected horizontally and some are connected vertically.

The Protostack Development Kit

Today I checked out the Protostack Development Kit. This is a board that comes with an AVR microcontroller and the necessary components to get the microcontroller up and running.

Basically that means it comes with a voltage regulator, some capacitors, an LED, a power connector and a connector for an ISP programmer.

Using Your Soldering Iron In Another Country

Have you ever considered bringing your soldering iron on vacation?

I am in Mexico at the moment and of course I have my soldering iron in my suitcase. But here the other day I got myself a surprise that I never considered could be a problem.

ERSA-30 Soldering Iron

I have an old ERSA-30 soldering iron that I inherited from my dad. It’s designed for the European 220V wall plug. Therefore I used an adapter to make it fit the Mexican wall plug. It’s not a converter, just a simple mechanical adapter that lets me plug my European plugs into the Mexican plugs.

I wanted to solder some stuff, so I plugged it in and waited…

Today featured as the “Engineering Site of the Day”.


EEWeb is a big website with lots of resources for electronics engineers, so I am honored to be featured as their site of the day =)

Check it out:

I have put a lot of effort in to, so being recognized like this makes me really happy =)

Arduino Remote Control Tutorial

In this tutorial we will make an Arduino remote control. It can be used to copy any remote control.

IR diode connected to Arduino

A remote control sends out an infrared (IR) code when a button is pushed. This IR code is received by the gadget we are controlling. To make our own Arduino remote control, we need to copy the IR code that is sent.

To create our remote control we need to:

  • Get button-code from original remote
  • Make a remote-control program
  • Upload our program to the Arduino

We will use these components for our Arduino project:

  • Arduino
  • IR Receiver TSOP31238
  • IR Diode
  • 100 Ohm Resistor

Make A Plastic Project Box

A plastic project box is nice to have to make your project look better. This has always been one of my weaknesses. I can make a really advanced circuit, but when it comes to package it, I have some kind of disability.

ADBO - Plastic Project Box for Arduino (laser cut)

Luckily there are some tools out there for people like me.

Here are three methods of making a plastic project box for you circuit:

  • 3D Printing
  • Laser Cutting
  • Modify Standard Boxes
