Breadboard wiring aid tool

1/5/2015

I received an Email from some kids at Stanford University in the USA about their Kickstarter project for a tool to aid with cutting wires and component leads to the right length when breadboarding.

I's a really nice, simple idea.
You can watch a short video presentation here.

Good luck guys.

Bat detector

I've added breadboard construction details for my bat detector mentioned some time ago. Breadboard documentation software is getting better all the time and after a recent search I found a pretty good one to play with, but it's far from perfect. It's a pig for example to create new parts and the existing library is pretty good but it's by no means complete.

Breadboards – Great, till they go wrong

Using breadboards, I often build project prototypes in stages as it makes sense to prove that each section works before moving on. I’ve just started another project and was confused as to why a part of it wouldn’t work. At first I suspected faulty components but ruled that out. After using my logic analyser to check the data flowing and convincing myself that the software was ok I was at a dead end. It was by pure accident that I found that one of the sockets on my breadboards is faulty.

This is one of my oldest breadboards and has given me many years of service, but it looks like it may be time for the scrap heap.

The video shows that the spring loaded contacts beneath the hole won’t grab a piece of wire.

I’ve never had a socket fail before like this, so, in future this is something that I will keep my eyes open for.

Breadboard +5v PSU carrier PCB

I've added a new construction project for a plug-in PCB module for breadboards.
It allows one of those cheap and nasty plug-in mains transformer type PSU to be used as the power source for a +5v regulated PSU thats suitable for powering PIC, TTL/CMOS logic and other circuits.
Because there's no direct electrical connection to the mains, it's perfectly safe for beginners to create. You can also throw one of these together for less than £2.00

If anybody in the UK is interested, I've got a couple of blank, etched and drilled PCBs that I'll give away on a first come, first served bases. All I ask is for £1.00 to cover my postage and packing costs. All you need to find are the 13 components to assemble the thing.
