A few weeks ago we wrote about our Bus Pirate universal serial interface tool. We used the recent holiday to add some new features, like a JTAG programmer, macros, frequency measurement, and more. A major code reorganization makes everything easier to read and update.

Check out the a demonstration of the new features below. We’re compiling a roadmap and wish list, so share your ideas in the comments. You can also see how we used the Bus Pirate to read a smart card and test-drive an I2C crystal oscillator.

Nintendo 64 Crammed Into A NES

[Matthew] sent us this Nintendo 64 stuffed into an NES. He did a great job really, everything looks nice and tidy. the presentation is decent with only the game ports visible on the front to tell you its not stock. The accent lighting on the side vents is not overpowering. Overall this was a really well done mod. Just like the Nintendo 64 in a Wii mod, this only plays Nintendo 64 games. OK guys, lets get some mods going that don’t involve cramming one Nintendo product into another Nintendo product.

Using VFDs As Amplifiers

tube_amp

[HP Friedrichs] sent us this cool writeup on how to use scrapped Vacuum Fluorescent Display tubes as amplifiers. For those unfamiliar, a VFD is a display device common to electronics. Many have been replaced by LCD, but you can still find them in modern products. [Friedrichs] points out that his 2008 ford has a VFD for the multimedia display.

Since these units are basically tubes, he figured that you should be able to use them as a tube amp. After some testing, he found it to be quite adequate. The project includes tons of background information on how tubes work, how VFDs work and how to utilize it for amplification. In the picture above, you can see him using one (middle) to amplify a home made radio (right).

Hackit: Netbook Haters?

eee

Gadget blogs have been a fluster the last day about TechCrunch stating that netbooks “just aren’t good enough“. Writing a response post hasn’t proven very hard given the number of factual errors in the original. Boing Boing Gadgets points out that the low-end of the spectrum that TC post seems to cover are almost impossible to purchase because they’re so outdated. Liliputing rightly states that comparing the browsing experience to the iPhone isn’t worthwhile since it’s entirely a software problem. Laptop goes so far as to recommend the HP Mini 1000 and Samsung NC10 specifically for their keyboard. TechCrunch isn’t alone in their opinion; this week Intel stated that using the ultra portable devices was “fine for an hour“. TechCrunch is designing a web tablet right now using the collective wisdom of blog commenters. Looks like they’re just reboxing a netbook for the prototype.

We cover the netbook market for different reasons than most: Their low low price makes people much more willing to hack on the device. For the price of a smartphone, you’re getting a fully capable laptop. The low performance doesn’t matter as much since we’re running different flavors of Linux that are much lighter than Windows. People running OSX86 are doing it to address a market that Apple doesn’t.

What’s your experience with netbooks? Do you have one that you adore or are you annoyed by their shortcomings? Models we’ve covered in the past include the Acer Aspire One, Asus Eee PC, Dell Mini 9, and MSI Wind.

MIDI Drums For Guitar Hero And Rock Band

Embedded above is [egyokeo]’s solution for using MIDI drums with Guitar Hero. He’s playing a DrumKAT MIDI kit. It connects to a PC running his MIDI Hero software, which handles timing and multinote combinations. The PC uses a USB ToolStick microcontroller to send commands to the console using an FPS adapter or soldered into the instrument. It’s a fairly good solution if you’re building a generic controller and need to modify the signaling.

When Rock Band was first released, modders sought to adapt their MIDI drum kits for use with the game. The easiest solution they found was Highly Liquid’s MSA-P. It’s a photorelay based MIDI decoder. You need to solder directly to the brain in the Rock Band drums. If you’re planning on modding any instrument, check the compatibility matrix first. Hopefully you’ll end up with something that can be used across multiple games.

The Dallas Personal Robotics Group held their semi-annual Roborama contest on Saturday November 22nd in Garland, TX. The DPRG had a table at the recent Austin Makers Faire. Each spring and fall, they hold the Roborama contests for autonomous robots. The spring event has contests for outdoor self-navigating robots. The 2008b contests were designed to test the abilities of indoor robots. Normally held at the Science Place, this year they elected to have the contests at the DPRG warehouse in Garland.

Upgrade An Electric Lock Keypad

lock_buttons

[OldGrover] bought a Weiser electronic lock. Only 6 months after installing it, the keypad stopped working. Instead of just accepting this, [OldGrover] built a better button pad for his lock. He decided to go with big push buttons instead of a similar to stock membrane system. After tracing out where the original buttons connected, he attached his new buttons and enclosure. Pretty simple really but it fixed the problem and kept the lock out of the landfill. Now, he has a unique looking keypad on his front door.
