Sharing the Love

Share Alike

Today I was asked if I could share my soldering iron hack PCB.

So I did!

A Simple Plan

Exploring New Stuff

A Simple Current Shunt Amplifier

A while ago, I took advantage of a free PCB offer to knock up a quick project, which is still 90% finished.  Or more correctly, not finished.

Alarm Fob Replacement

I Hate Being Ripped Off

My home alarm remote control had seen better days.  After more than six years of abuse, the case was finally cactus, as can be seen below.  My wife's fob was in better shape but it's days were also numbered.

On the 16th of May Altium released Beta 1.04 of Circuit Maker, and opened the beta testing to all.  

You bet I was keen to try it!

The info below was true for the closed Beta, but no longer is the case.  The open beta now offers no limitations, and in the words of the CM team, free should be free!

PSU Console

Dead Simple Power Supply

At work I'm quite spoilt, there is an abundance of equipment in the labs, and if I need, I can borrow something for home use.  Very handy when ding something specific (like the thermocouple I used here) but it comes with a down side.

If I realise I need something, it means dropping work for a few days until I can borrow the equipment (if it's in use at work, I can't have it until it's free) and as I catch the train, it also means bringing the car in if it's too big to fit in my backpack.

When it came to powering my projects, I have a very basic dual rail Power Supply (I built one just like in in Uni, tortured it to death over the coming years by running a car amp from it in my bedroom) that I inherited from a guy-who-got-it-from-a-guy-from-a-garage-sale deal.

The updside: It's got dual isolated rails, 1.25V to 15V range and 'up to' 1A output.  

The downside: It's so old the pots are scratchy, so setting an output voltage is a chore, and there isn't any current limit.  And you need to whip out your multimeter to set the voltage / measure the current in use.

So I got cracking on this:
