Electrical Hardware
Just getting the hardware together for the power supply for the KosmoNought synthesizer. Mains comes in through the IEC connector and is switched on both the Live and Neutral. The switch was free – it was surplus to requirements at the company where I work. It has a neon bulb inside which illuminates when the…

Safety First
As I mentioned in a previous post, there is no mains terminal cover on the power supply and I said that I’d 3D print one. As luck would have it, somebody else had already done just that and posted their design on Thingiverse. So I loaded it onto my 3D printer and set it going. …

Getting Organised
When you embark on a construction project of any kind, it pays to get organised. For example, I often buy electronic components that I know that I shall need for one or more of my projects, long before I need them because I take advantages of special offers and discount deals. Consequently, I end up…

KosmoNought Gets Its PSU
When I built the KosmoNought case I was pleased with a job well done, but I knew that I had to get something inside it to get that real feeling of having started the project. Now the first piece of electronics has arrived in the form of a Mean Well RT-65B* power supply. This is…

Why I Used a Commercial PSU in My Synth Project
I previously said that I was going to build as much of this synthesizer as possible. I decided that one exception to that would be the power supply unit (PSU). All though I understand the electronics of power supplies and could probably build one that provides the +12v, -12v and +5v that it requires, I…

KosmoKase
This is the first part of my KosmoNought modular synthesizer. It doesn’t make a sound and it doesn’t modify sounds. It’s the case. I have built it first because that is where everything else will reside and I don’t want a rat’s nest of wires all over my workbench while I build this thing. I…

DIY Modular Synthesizers: From Concept to Creation
When I was a teenager and getting interested in hobby electronics, I really wanted to build a modular synthesizer. There were plenty of electronics magazines offering projects to build them, but on my very low income, they were beyond my reach. Now, many, many years later, I have a decent income, have paid off my…

A PS/2 Keyboard Interface
When commencing the journey into retro, 8-bit computing, it’s very tempting to start with the microprocessor, add in some ROM and RAM, get some kind of display working, and then add the required hardware such as a keyboard or keypad. I have decided to work the other way around and start with the keyboard. That…

Retro Computing
Retro Computing seems to be becoming more and more popular, and I’m all for it. My first computer came as a blank printed circuit board (PCB) and bags full of resistors, capacitors, integrated circuits (ICs) and IC sockets that I had to solder to the board myself. There was no concept of buying a motherboard…

Hello world!
Welcome to Boscombe Dynamics. I don’t make robots, and I don’t plan to in the foreseeable future. If I did, I’d use a different company name so that I didn’t end up with a lawsuit. If you’re looking for cool robots, go to Boston Dynamics. This post is called Hello world! because that’s the traditional…
