Open Source STM

We hope you paid attention in advanced theoretical and quantum physics classes, or making your own Open Source Scanning-Tunneling Microscope might be a bit of a doozy. We’re not even going to try to begin to explain the device (honestly we slept through that course) beyond clarifying it is used for examining the molecular and atomic structure of surfaces; but for those still interested there is a nice breakdown of how Scanning Tunneling Microscopy works.

Z80 emulated on PIC hardware

[Jaromir Sukuba] built a very portable, low power consumption Z80 emulator using a PIC microcontroller. Looking through his build photos we love the clean and resilient construction which includes a breakout board for the PIC 32MX795F512H that interfaces with the main board via pin headers and sockets. He’s using a home-built keyboard and a 4×40 character display but there is also the option to communicate with the device over an RS232 connection. Oh, and yes it plays Zork, which seems to be the benchmark whether you are emulating a Z80 with AVR hardware, or if you built one from transistor-transistor logic.

Hack a Day store now open

Since the beginning of the universe we’ve been getting requests for stickers, shirts, coffee mugs, etc.  Well, several of the writers have the ability to produce this stuff in their homes. The boss liked that and gave us his blessing to start selling Hack a Day stuff.

In the interest of keeping the cost as low as possible, right now the store is located inside of my personal online store. The only products we have right now are stickers, since I make them myself. Though if enough of you pester him, maybe [Devlin] will make up a batch of those Hack a Day badges.

Please be patient with the store. It is fairly untested and tossing this many people at it at once is somewhat frightening. If you have any problems at all, please contact me (caleb@) and I’ll take care of it. You can get to the store by clicking the new button on the right of the screen, labelled “store”. You can see a few more pictures after the break.

Note: Thos of you who are outside of the US, please just contact me directly. I have to figure out your shipping outside the system. Don’t go fill out an order.
