What is FabISP? FabISP is an In-System-Programmer for well known AVR microcontrollers. This programmer is designed to be build at your home lab using common production procedures. After you build this programmer you will be able to programm your AVR without removing it from your board. To programm the chip you can use Avrdude software. Schematic, pcb, firmware and eagle files are available on the link below. It’s a well designed programmer. [via]

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.

Can you make an iPhone out of an AVR? No. Can you get a surprising amount of functionality out of a humble 8 bit processor and a cheap touch LCD? Yes. The iPhone runs more than 30 times faster (417Mhz ARM vs 12Mhz AVR) and has more than 30,000 times as much ram RAM (128M vs 4k) yet this frumpy little device can ape some of the iPhones neater tricks.

This basic hack shows how to burn the bootloader onto the Atmel chips that the Arduino controller uses without the need for an external AVR Writer. Simple soldering skills required, but if you are using an Arduino, you are probably already a soldering pro. [via]

I decided to make JAREK ZIEMBICKI’s AVRSYN. But there were only the schematics and no board layout so I had to make my own. So I started laying it out on eagle but I got on a deadlock due to the fact that I didn’t want to make a double sided board. I would etch it myself and double sided boards are a BIG pain in the but (vias and such, alignment etc). So I made it on a perfboard. But before that, I decided that it should be made into discrete modules. One for the microchip, one for the D2A (an R2R resistor ladder type) , one for the midi interface, one for the power supply and one for the switch multiplexer.

How to connect a Nokia LCD to a AVR-Controller. he Display (which is used in Nokia 6100, 7210, 6610, 7250 and 6220) has a resolution of 132×132 pixel @4096 Colors. The visible area is about 3cm x 3cm in size. It can be found cheap at *bay.

Rob writes that he’s created a custom Arduino AVR library for EAGLE that lets you easily integrate Atmel’s ATMEGA168 and ATMEGA8 microcontrollers into your designs. You can download this library from the link below. [via]

This project makes firmware upgrades easy: The target has an Infrared receiver and the data is sent via IR. The IR transmitter is based on AVR-USB.The host-side consist of host-program for Win32 PC using Libusb-Win32, device based on ATmega8 using firmware-only USB driver by Objective Development and infrared hardware unit.Host program was compiled using Lazarus Freepascal. Device firmware was compiled using WinAVR (AVR-GCC).The implementation uses custom device class, required simple inf file and libusb driver on PC. [via]
