Mike's Electric Stuff

Mike's Electric Stuff Each of the three main sections has a 'tour' facility for easier navigation through the pages - clicking on the small icons at the corners of each page will move to the next or previous page in that section. Upcoming public demos, events etc. I'll be participating in None at present. I can often be found lurking or presenting at Dorkbotlondon meetings. Check my Youtube channel - new stuff is most likely to appear here at the moment so subscribe!

Learn Bil Herd’s DIY Surface Mount Assembly Process You can do your own Surface Mount Technology based PCB assembly with just a handful of tools and some patience. At the heart of my SMT process is stopping to inspect the various steps all while trying to maintain a bit of cleanliness in the process. Surface mount or Surface Mount Technology (SMT) is the modern way to assemble Printed Circuit Boards (PCB) and is what is commonly seen when opening a modern piece of tech. It’s much smaller than the older Through-Hole (TH) technology where the component leads were inserted into holes in PCB, and act we called “stuffing” since we had to stuff the components into the holes. A few specialized tools make this a lot easier, but resourceful hackers will be able to pull together a solder paste stencil jig, vacuum tweezers, and a modified toaster oven with a controller that can follow the reflow profile of the solder paste.

The Transistor Lists of Nobel Prizes and Laureates The Transistor Play the Transistor Recycler Game About the game A transistor is made of a solid piece of a semiconductor material and either used as switches, to turn electronic signals on or off – or, as amplifiers. Zener Diode Circuits and Applications - a summary or tutorial covering the essentials of the Zener diode or voltage reference diode used in many power supply and other circuits. Zener diodes are used in many circuits in a variety of ways. The most common Zener diode circuit is one in which the Zener diode is used as a voltage reference element. This type of circuit uses the constant voltage as a reference in one of a variety of forms of power supply circuit.
