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…
