Well, Christmas may over but we think you may take a look at this well designed PCB Christmas tree and why not consider building it for the next year. Since I already have an Arduino, and I felt pretty comfortable with it, I decided to use it to control the LEDs. However a full...

Sjaak has published a new PCB build, uC controlled dummy load: With no snow outside I finally got around to solder the 3rd PCB. It is the second revision of a microcontroller dummy load. It is loosely based on the arachnidlabs uc:load. It uses the same base ciruit and adds a...

Here’s an alternative method for making PCB vias using conductive ink from Diyouware: We developed an alternative method for making PCB vias through-hole using our robot. As you probably know the traditional DIY method consists in threading a wire through the holes and then...

TMLM family of 4-20W AC/DC power supply is the right solution on most important requirements – constraint space, high efficiency and cost saving. Every square inch of your PCB costs money. It is a fact, and if you can reduce your PCB´s area, you actually save money. Moreover if...

Floyd-Jones designed his own business card using logic circuitry. He writes: The card implements a digital finite-state machine which displays the next character of my last name on a 7-segment display each time the button is pressed. Luckily all 11 characters in my name can be...

by Giuseppe Finizia @ makezine.com: I am the Senior Analyst of the Electronic Forensics Unit of the Carabinieri (Italian Military Police) and I deal with technical investigations on seized electronic devices. I spend most of my day in a well-equipped electronic laboratory, but I was...

Ilia Baranov has designed a reference business card: Back of card includes: Ruler in both 1/10″ and mm. AWG Hole size gauge (not super accurate due to plating, but that is unavoidable) Resistor/capacitor/inductor/diode sizes Common surface mount component sizes Common...

Gonazar’s PCB stencil jig: My solution to making a PCB stencil jig. I need this to do a run of ~30 small boards I got from DirtyPCB who also provided me with the stencil. However, I know that I’m going to be making more later with a new revision so I wanted a jig that I could...
