[Ben Krasnow] is capturing some great snapshots using a microscope adapter and some tricks. The camera attachment is just a lens adapter ring with a tube added. Unlike other microscope imaging hacks we’ve seen he used a real microscope but found that the pictures had a bit of light distortion to them. The camera sensor was picking up a glare reflected on the inside of the black tube. By adding a washer and repositioning the apparatus he got over that hurdle. The final part of the puzzle is image processing. By taking several pictures at different focal lengths and compositing them he gets killer photos like the compound eyes of that house fly seen above.
[Mark Bog] thought it was a waste to use batteries for his desktop touch pad. Quite frankly we agree that if you can avoid using disposable cells you should. He ditched the dual AA batteries inside of his Magic Trackpad and built a battery-sized adapter to feed it some juice. It consists of a dowel of similar diameter with a screw in each end. He scavenged a USB cord, connecting hot and ground wires to the corresponding pole of the adapter. Now his Trackpad is USB powered and never in need of a battery replacement or even a recharge.
We’re not familiar with the inner workings of Apple’s Magic Trackpad. We assume there’s a voltage regulator inside and we hope it doesn’t have a problem working with the 5V regulated power coming in from the adapter. If you’ve got the skinny on the hardware we’d love to hear about it in the comments. One last thing: because the forum linked above requires a login to view the images in the post, we’ve embedded the rest of them after the break for your convenience.

[Chlazza] let us know about their Xbox hard drive to SATA adapter, allowing the use of an Xbox 360 (original) hard drive on a PC without voiding the drive’s warranty. Looking for a fun and enriching experience read: really bored and inspired by a previous adapter we featured, [Chlazza] set out to make their own and ended up succeeding with a board that costs less than $1 in parts. Of course the drive uses its own Fat32 based file system so there is still some hacking to do if you intended to read the data, but this is a step in the right direction.
[Geordy] added a serial port to his Zipit. It uses a 3.5mm jack as the connector. He managed to include an RS232 level converter inside the case. Both components were hard to fit into the cramped quarters but he did it and he kept the hacker-friendly device looking nice too.
Standard connectors in portable devices would be great for the consumer, but then you wouldn’t purchase separate peripherals for ever portable you buy (lining the pockets of the companies licensing said peripherals). [Thijs] isn’t taking it lying down any longer. Realizing that the shape of the connector is one of the only things standing in the way, he built an adapter to use iPod docks with Droid. The hardware consists of a USB connector, audio jack, iPod connector, and a magnet. After working out the wiring it was just a matter of building a chassis using polymorph material. As you can see above, his expensive dock has no problem playing nicely with Droid because of his handy work.
Here’s another SNES controller converted to house a USB system. The one we saw last time used a kit as an adapter for the controller but this version uses a home-built PCB and an ATmega8 microcontroller with the latest revision of an open source adapter for NES and SNES controllers. As you can see after the break, [Atarity] built the adapter, then added it along with a USB hub and thumb drive so that he could run a copy of XBMC from the controller. Now he’s got XBMC as a way to launch emulators for those classic games, as well as play traditional media.
You will be seeing more of this type of mod soon. We were tipped off that an in-depth tutorial for SNES controller hacking is on its way, although that is unrelated to [Atarity’s] work.

This is a “why didn’t I think of that?” idea. [Alec] needed a way to connect an IDE DVD drive using USB. Rather than order a connector he pulled the circuit board out of an old USB hard drive enclosure and connected to his DVD drive. Bang, recognized and running.
This will prove extremely handy if you have a netbook without an optical drive. We’ve used Unetbootin to move Linux ISO images to a thumb drive in the past. In addition to getting around the lack of an optical drive, this saves burning the data to a piece of plastic. But, you should be able to use this with a Leopard retail DVD instead of a 16GB thumb drive for a Hackintosh conversion. That means you could install Leopard on a netbook without needing a Mac to transfer the disk image to your thumb drive first.
