Single chip AVR BASIC computer
Dan over at HackAday documented his single chip computer project with the PCBs from DirtyPCBs: A single AVR microcontroller (the ATmega 1284P) has been used to create a standalone computer system which runs the BASIC programming language. The 1284P runs TinyBASIC Plus, generates RCA video signals (using TVout) and reads PS/2 keyboard input. A single sided […]

ATTiny85 breakout board
Shady994 shared his first PCB an ATTiny85 breakout board in the project log forum: I (badly!) soldered up my first PCB, an ATTiny85 programming/breakout board. It also has a header so I can connect it to my Bus Pirate, which I’ve been using as a programmer.

0-30V laboratory power supply
Hare’s the 0-30V laboratory power supply project by Arief Laksono of Electronics Lab: This project is based on the 0-30 VDC Stabilized Power Supply with Current Control 0.002-3 A and a new PCB layout is introduced here. It’s a stabilized power supply with variable output voltage in the range 0-30Vdc (33Vdc peak) – and variable current 3A and […]
RTCC shield kit with a prototype PCB from Dirty PCB’s
@Velleman_RnD tweeted, “RTCC shield kit. Proto pcb made by the good people from Dirty PCB’s”
Arduino pro mini undershield
Bajdi blogged about his Arduino pro mini undershield: I’ve designed another PCB :) This time it’s a simple undershield for the Arduino pro mini. I received the PCB’s from Electrodragon (12$ for 10PCB’s) last week. The PCB has a schottky diode and a 5V linear regulator, I’m using an LM2940 5V regulator. For the rest there […]
DP6037 Protoboard v1 PCB back in stock
The DP6037 Protoboard v1 PCB is back in stock at Seeed Studio. A multipurpose 0.1″ pitch prototyping board that fits a DP6037 acrylic case. Grab a PCB from Seeed for $2.50.
Dr Brown’s capacitor ESR tester
Rupert Hirst writes: I finally got round to making my capacitor ESR tester this week after finding a nice simple 5 transistor version by EEVBlog member Jay_Diddy_B. Unfortunately, for me, the design was only SMD so, I decided to replicate his schematic in Eagle PCB using a through hole component design.

Sick of Beige board layouts in Altium
Check out Zeke’s Sick of Beige PCB layouts in Altium: I have finished creating all the SoB pcb sizes now. I put a zip file up that contains the Altium project file plus all the pcbdoc files. Via the forum.

Proto Cape for BeagleBone
Tom shared his prototyping cape for the BeagleBone/Black in the project log forum: I spun a prototyping cape for the BeagleBone/Black. The design is derived from the LGX Proto Cape created by Alexander Hiam for LGX / Logic Supply and released under Creative Commons Attribution 3.0 Unported License. I removed the SMD component footprints, which seemed […]
App note: PCB design for 10/100 switches and PHY
Design guide on PCB layout from Micrel on 10/100 switches and PHY This application note is intended to assist customers in designing products that comply with both EMI and ESD standards using Micrel’s 10/100 family of Ethernet products. The printed circuit board (PCB) is the single most important factor that affects EMI, ESD and overall […]
Kevin’s LED tester
Kevin Rye designed a simple LED tester: I decide to put together a small LED Tester board. It’ll be powered by a small coin cell battery. I can pick up an LED with a pair of tweezers and just simply tap it to the solder pads. If it lights up, I know I’m holding it […]

PCBmodE: Make your PCB a work of art
Saar of BoldPort developed an open source software for creating artistic and functional printed circuit boards, the PCBmodE: We wanted to create circuit boards that have curvey traces, meandering paths, and multiple soldermask layers, so we developed PCBmodE (say “PCB mode”), an open source Python software that unshackle us from the constraints imposed by traditional PCB […]
App note: Damage from a lightning bolt or a spark—It depends on how tall you are!
Here’s an application note from Maxim describing how to protect printed circuit boards (PCBs) against ESD destruction: Large steel buildings, automobiles, mountains, even people survive real atmospheric lightning. Humans can also create their own miniature lightning bolts (sparks) and survive. When those sparks reach an IC, however, major trouble results. In this tutorial, we will discuss […]
