Panelizing PCB & Assembly: prepping the boards… If you want to send out PCBs for manufacture you can save a lot of money by tiling them, here’s a nice walkthru of using the open source gerbmerge tool to tile your PCBs.. [via]

I make a lot of breakout boards that I usually use in my hobby projects. Most are input/output devices but some are microcontroller breakout boards.

We released the 28 Pin AVR Development Board back in 2008 and since then it has gone through many iterations. This week we release version 1.6 which adds 4 improvements. These improvements were based on customer feedback and we are very grateful for the feedback. Please keep it coming.

During my work for the digital power supply I needed to start playing with some micros from the XMEGA family, that is why I build this little header board. There is a XMEGA32A4 micro on it, which is the one that I intend to use on my power supply.

Protoflex is a set of flexible circuit board stickers for SMD development. Peel off a footprint, stick it on 0.1″ protoboard, and solder surface mount parts directly on the sticker. Brilliant use of flexible PCBs. [via]

For an electronics hobbyist, knowing how to do PCB design is a must. Building prototypes on breadboards or with wire-wrap just doesn’t cut it, once you reach a certain point. Then, a PCB board needs to be made specifically for your project. The previous tutorial Homemade PCB (Etching) showed you a quick, simple, dirty and easy way to make your own PCB. This tutorial will expand further and show you how to make a 2 layer (top and bottom) pcb.

This project is a mini board for use with AVR ATtiny2313. Somewhat similar to PIC 12f675 mini protoboard, but extended and with additional boards.

This project shows how to build a LED holiday tree using a custom made circuit board. The circuit board is made using a Dremel rotary tool and doesn’t require any etching chemicals. You use the Dremel tool to cut a copper into a tree shape and route the two separate PCB sections that will power the LEDs. The LEDs and resistors will be soldered at the surface of the board. The result is pretty nice. Check the construction PDF on the link below.

Back in July 2009, we reviewed Protostack’s ATMEGA8 development kit. The heart of the kit was Protostack’s 28 pin AVR board. This week Protostack released a new version of that board and it includes a whole bunch of improvements. You can read the original review here.

This release is the 3rd one to date and includes the following improvements over the one we previously looked at.

  • Addition of power supply block
  • ISP-6 interface is now 2×3 pin instead of 1×6 pin
  • Addition of a section for double row headers and IDC connectors
  • Clearer labeling of power busses

The board is available on its own or as part of an ATMega8 or ATMega168 development kit from www.protostack.com. Pricing starts at $9.60 for a single board.
