[Alexsoulis] needed to burn the Arduino bootloader to a slew of ATmega328 chips. Instead of sitting there and plugged the chips into a programmer one at a time, he build a robotic microcontroller programmer.

It starts with the DIP package microcontrollers in a tube, with a servo motor to dispense them one-by-one. An arm swings over and picks up the chip with a fish pump powered vacuum tweezers similar to the pick-and-place head we saw recently. From there the chip is dropped into a ZIF socket and programmed by an Arduino. Once the process is complete it is moved to the side and the process repeats.

We’ve reported on using an Arduino as an AVR programmer but we’ve never actually done it ourselves (we use an AVR Dragon programmer). Take a look at the video after the break and let us know if you think the actual programming seems incredibly slow.

We looked at [Gerry's] PLCC based programmable Game Boy cartridge back in May and mentioned that he was working on a how-to video. He did quite a bit more than that. He’s made a PDF version of the instructions but went into deep detail with a collection of four videos on his YouTube channel. We’ve embedded all four after the break. They include an introduction and background about the cartridges, desoldering the ROM chip, preparing sockets and wire, and making the solder connections. Whether you’re interested in this particular hack or not, seeing [Gerry's] soldering practices make the videos worth watching.

We love our AVR Dragon programmer. It is a small board with a lot of functionality: in-circuit serial programming, JTAG, debug wire, and high voltage serial programming. Unfortunately, out of the box it is not quite ready for action. The Dragon ships with an unpopulated prototyping area and missing a pin header for the HVSP. For most people this means soldering on pin headers and a ZIF socket then jumpering between the various programming headers and the header for the socket. Tired of working with jumper wires, [Jussi] designed a small PCB to make the connections (original link in Finnish). Read the rest of this entry »

Evil Mad Scientist Laboratories has put out this nice tool. It’s a Zif socket for Arduino. If you’re doing a lot of flashing, this could be a nice addition to keep from having to pry your chip out every time. Plus, it looks cool in a soviet era technology kind of way.

Evil Mad Scientist Laboratories has updated their business card AVR breakout boards to version 1.1. We suspect the changes will probably make them even more popular. The boards are designed for the ATmegaXX8 family of microcontrollers. The center has all 28 pins labeled while either end has a prototyping area. An in-system programming header is also provided. For the new version, both prototyping areas have been increased to accommodate DIP14 packages. The holes for the microcontroller are now larger so that they can hold a ZIF socket. Finally, the power and ground traces have been expanded. We’ve always like the versatility of these boards, as demonstrated in the Tennis for Two project, and can’t help wondering if these updates were made to facilitate another project.

As promised, [tnkgrl] has published part two of Acer Aspire One upgrade. In part one she added Bluetooth and more RAM. This time around she focuses on the storage. The subnotebook comes from the factory with an 8GB SSD. The flash based storage readily unplugs from a small ZIF connector. [tnkgrl] replaced it with a 60GB PATA Samsung drive salvaged from an iPod. It’s a 1.8inch disk and is only 5mm thick, so it can be tucked under the motherboard. Knowing its previous use, it should prove fairly resilient. You can view a video of the swap and more photos on Flickr.

Up next is part three, where she’ll add 3G support.
