NES Workbench

[Miltron] dropped us a tip about his NES workbench.  Knowing that when you get frustrated with whatever project you are beating your head against, you need an outlet, [Miltron] decided to build some relaxing NES fun into his workbench.  He’s using a NES on a chip though any multi game-in-a-controller setup should work. He has gutted a PSone LCD and mounted it all together nicely so he can game at any moment.  You might recall one of [Miltron]’s earlier projects, Das Uber Airsoft Turret. How long will it be before we see integrated LCDs into our toolbox lids or workbenches from the factory?

Adding RDS Decoding To A Vintage Radio

[Edo] wrote in to show us how he added RDS decoding to a radio made in 1957. RDS or Radio Data System is a protocol for data transmission. This allows date, time, artist info, and more to be broadcast along with the music. Its a nice feature that many new cars come with from the factory. [Edo] wanted to add it to his old radio though. He kept the radio stock looking, choosing to use an external LCD to display the data. He has posted the information on where to splice in to add this unit to pretty much any FM radio as well as posting the schematics and source code for the unit itself. Look at the very bottom of the page for the download link, its a bit hidden with the advertisements.

Bus Pirate Preorder 2 Update

A few weeks ago we held a preorder for the Bus Pirate universal serial interface tool. We split the preorder into two parts due to a shortage of PIC 24FJ64GA002-I/SO chips. The first preorder is arriving worldwide now, the second preorder has a longer lead time. Here’s everything we currently know about preorder 2, it’s subject to change, but we wanted to keep you up to date.

Preorder 2 contains orders for 563 Bus Pirates. Seeed Studio noticed an error in our quality control testing routine that misclassified about 50 preorder 1 Bus Pirates as defective. We updated the test and passing units will ship immediately to preorder 2 participants on a first come, first serve basis. Another 500 PICs are scheduled to arrive after August 1, which should take care of most remaining orders.

Camera Peltier Cooler

[Gary Honis] has been modifying his Canon Digital Rebel XSi in order to do astrophotography. He previously removed the IR filter and replaced it with a Baader UV-IR cut filter that lets most infrared light through. However, in order to reduce noise in the pictures, he had to cool the camera down. He based the project on a peltier cooler that he salvaged from a powered beverage cooler. He made a small aluminum box and insulated it with styrofoam to hold the camera body. The peltier cooler was then attached on the side. It takes just over an hour to cool the camera down to 40 degrees, but the shots come out a lot clearer.

Open Source Logic Analyzer

[Jack Gasset] sends in the logic analyzer he’s been working on. The logic analyzer boasts an impressive array of features, it can sample 32 channels at 100MHz, 16 channels at 200MHz, SPI, UART, I2C and more. The analyzer’s maximum sample size is 4K for now, and it supports RLE to reduce the memory consumed. The analyzer connects to a java client on a standard PC via USB. The open source hardware based on a Xilinix FPGA can be purchased pre-assembled for $100 which makes it a direct competitor for the Salea logic analyzer we reviewed earlier this year.

Snake Bot

sb head (Custom)

[Husstech] wrote in to share his Snake Bot with us. Initially inspired by this post about SickSack, a snake bot, he set out to build his own version. While the concept and even the design aren’t particularly new or groundbreaking, he is very thorough in his documentation. Since this was a project for school, the PDF of his project includes research, schematics, cost breakdowns, and results. We really like the camera and head design, it looks very insect like. You can see a video of the final version being shown off after the break, or you can see an earlier version that is decidedly more phallic.

Touchpad + Arduino

[Jani] directed us to his tutorial on making a laptop touchpad work with an Arduino. After seeing the recent post on touch pad and VFD hacking, he couldn’t resist finding one of these to play with. He shows us how to connect it all up and offers two methods of using the data from it. The first method is to determine the direction of finger travel and the second, shown above, is to use it more like the volume control on an iPod. Source code for both is available on his site.
