[Jeri] Builds A C64 Bass Keytar

May 23, 2012 by Caleb Kraft 23 Comments

[Jeri] built this really cool C64 bass Keytar from a commodore64 and a cheap bass guitar. She’s using an FPGA to do the string detection and the key scanning, it then sends everything to the original 8bit sound chips. The reason that she is using a bass guitar is that the commodore sound chip only has 3 channels. There’s an interview with her from the maker faire, and if you keep watching, there are some other interesting projects too.

She notes that the implementation she went with has many performance issues due to the overtones the strings create when played. If she did it again, she’d go another route. Since [Jeri] has previously created the fully functional C64 games on FPGA, maybe she’ll add some video synth to this down the road.

SpaceX Finally Launches, [Scotty] Makes It To Space.

May 23, 2012 by Caleb Kraft 18 Comments

We’ve been eagerly anticipating the first launch of our new space era. Like it or not, NASA isn’t going up anymore, so someone else has to. When we posted that the launch event was going to be broadcasted live (which ultimately failed), there was a lot of debate in our comments on the subject of private vs government entities doing the space traveling. There was also a lot of childish bickering.

Just to clarify, Hackaday’s official stance is, “Go to space”. We do not care if it is the government, [Elon Musk], The russian space program, a hackerspace in a home made rocket, or an evil billionaire. We just want space research to continue. Sure, there are drawbacks to some of these, most notably that the evil billionaire would most likely be doing this to kill us all, but at least the research would be funded.

You can watch a short clip of the launch, and while you do so, remember that on board that ship are the ashes of actor [James Doohan] also known as [Scotty]. That’s pretty awesome.

Macetech’s LED Glasses Prototype

May 22, 2012 by Caleb Kraft 9 Comments

While there was no mention of it on their blog, [Garret] from mace tech was spied wearing some pretty cool looking LED glasses at MakerFaire last weekend. This morning, we noticed a Lytro gallery of the glasses and they look pretty cool (as a toy, not a fashion accessory). For those who haven’t played with Lytro, you can click around and refocus the image. Neat right? Back to the glasses.

Someone who we’re guessing is [Garret] spoke up on Reddit this morning explaining some tech specs and dropping a video of them in action.

The shades are a 20×6 matrix (with some pixel missing of course) driven by SPI from an integrated Arduino-compatible in the right temple. There is a Lithium-Polymer battery on the left temple. You can charge the glasses through USB, and download new code to it over the same connection. A button on the right temple allows switching between modes or auto cycling animated patterns.

Man, Stranded In The Desert, Makes A Motorcycle From His Broken Car

May 21, 2012 by Caleb Kraft 190 Comments

The original story is in French, and the Google translate is very rough. Please forgive us if we don’t get this completely accurate.

While traveling through the desert somewhere in north west Africa in his Citroen 2CV , [Emile] is stopped, and told not to go any further due to some military conflicts in the area. Not wanting to actually listen to this advice, he decides to loop around, through the desert, to circumvent this roadblock.

After a while of treading off the beaten path, [Emile] manages to snap a swing arm on his vehicle, leaving him stranded. He decided that the best course of action was to disassemble his vehicle and construct a motorcycle from the parts. This feat would be impressive on its own, but remember, he’s still in the desert and un-prepared. If we’re reading this correctly, he managed to drill holes by bending metal and sawing at it, then un-bending it to be flat again.

It takes him twelve days to construct this thing. There are more pictures on the site, you simply have to go look at it. Feel free to translate the labels and post them in the comments.

Update: From [Semicolo] in the comments

You got the translation right, but there’s not just a swing arm that’s broken, there’s a frame beam broken too (not sure about the exact term, one of the 2 girder of the chassis).
He’s not far away but he has a lot of tools and other hardware that could be stolen if he leaves them unattended.

Hackit: Leap Motions New Motion Sensor

May 21, 2012 by Caleb Kraft 73 Comments

The big news circulating this morning is of the Leap Motion sensor that will be hitting the market soon. They claim that their sensor is ~100 more accurate than anything else on the market right now. Check out the video to see what they mean (there’s another at the link). This is pretty impressive. You can see the accuracy as they use a stylus to write things. If you’ve played with the Kinect, you know that it is nowhere near this tight. Of course, the Kinect is scanning a massive space compared to the work area that this new sensor works in. The response time looks very impressive as well, motions seem to be perfectly in sync with the input. We’re excited to play with one when we get a chance.

3d Printing A Mini Lathe

May 21, 2012 by Caleb Kraft 21 Comments

While browsing on one of our regularly visited sites, RobotsDreams, we found this interesting little video. Here, [Sublime] is showing off his 3d printed mini lathe. In the video he mentions that all the files are available for download so you could make one for yourself, but there were unfortunately no links. A quick bit of googling and we found some more information. We found the project on Thiniverse, though reading through the comments it seems that [Sublime] no longer uses Thingiverse. You can now find the files on his GitHub account to make your own.

The design seems very solid and looks like it could handle some basic jobs. As [Sublime] points out in the video below, you already know what parts are going to wear out fast and can simply print a few extras to have on hand. While that may seem somewhat wasteful, he also points out that he’s using PLA which is compostable and much easier to recycle.

Light Trikes Allow You To Pedal For Your Life

May 21, 2012 by Caleb Kraft 2 Comments

Unfortunately, none of our writers are located in California this year. This means that we weren’t able to go to the Bay Area MakerFaire and see the cool stuff for ourselves. We have been following along on the web though and a few projects have caught our eye. The rig you see above is a physical controller for a game that was inspired by the classic Tron light cycle. The gameplay is pretty obvious, you pedal the trike to go and turn the handlebars to turn your light tricycle. The hardware seems fairly simple, they’re using an arduino to collect information from the bike, then sending that through NetLab hub, a cross platform toolkit for taking data from a micro controller and feeding it to flash. We think they did a fantastic job on the presentation, this actually looks like fun to play.

For some reason though, we want them to build a level that looks like the Stanley Hotel.
