Repeating Timer No.9
New! This circuit has two independently adjustable 24-hour timers. There's a relay-timer that will energize the relay for up to 24-hours. And there's a repeat-timer that will restart the relay-timer - at regular intervals of up to 24-hours. It's a more versatile version of my first Repeating Timer.

Electronic Toggle Switch No.1
Update! I've added clear drawings and a photos of the - built and tested - breadboard layout. I've also added a free SiMetrix circuit simulation - and an improved fault-finding guide.

Electronic Toggle Switch No.2
Update! I've added clear drawings and a photo of the - built and tested - breadboard layout. I've also added a free SiMetrix circuit simulation - and an improved fault-finding guide.

Plan Your Breadboard Layout In Advance
Update! I've added a third template to the downloadable Resource File. I want to provide as many different breadboard templates as I can. So if there isn't one to suits your style of breadboard - please let me know.

How To Make Wire Links
Update! I use indoor telephone cable to make links for my breadboard and stripboard. The breadboard links are reuseable. So in this update - I've added a photo that shows how I sort and store them.

Download This Site
Update! You can download the current version of my entire site - in a Zip File. It's hosted by Google Sites - and it's under 20MB. It includes the current updates. Use it to work offline - put it on your website - or simply pass it on.

Constant Temperature Controller
New! This circuit is like a dimmer switch. As the temperature rises - the controller turns the heat down. When the heat output exactly matches the heat loss - the temperature stabilizes. And the controller maintains this stability by making one-hundred fine adjustments to the heat output - every second.

Two Cmos Based 24-Hour Timers
Update! I've added clear drawings and photos of the - built and tested - breadboard layouts. I've also added a free SiMetrix circuit simulation - and an improved fault-finding guide.

Two-Zone Burglar Alarm
Update! I've added clear drawings and a photo of the - built and tested - breadboard layout. I've also added a free SiMetrix circuit simulation - and an improved fault-finding guide.

Plan Your Breadboard Layout In Advance
New! I used to design my breadboard layouts "on the fly". I always ended up with a real mess. And it took me forever to find the (inevitable) mistakes. So I've adapted my Stripboard Design Technique - for the breadboard.

A Breadboard Layout For Motorcycle Alarm No.2
New! I used my Breadboard Design Technique to produce a layout for this 555 based battery powered alarm. I've included both a clear set of drawings - and a photo of the built and tested breadboard layout.

Designing Stripboard Layouts
Update! This page has everything you'll need to copy my design technique. I use a free programme called Inkscape. I've added some more component shapes - and an improved template that should be more convenient to use.
