Blinking lights is a lot of fun, but if you’re getting an EE degree the cool stuff becomes a bit more involved. In this case, building your own radar is the thing to do. Here’s a coffee can radar setup being shown off by a group of UC Davis students. Regular readers will recognize the concept as one we looked at in December. The project was inspired by the MIT OpenCourseware project.
One of the cans is being used as a transmitter, the other as the collector. The neat thing about this rig is that the analysis is performed on a PC, with the sound card as the collection device. The video after the break shows off the hardware as well as the results it collected. About a minute and a half into the clip they show a real-time demonstration where a student walks in front of the apparatus while another takes a video of the plot results. As the subject moves away from the receiver the computer graph changes accordingly. The rest of the video covers some operational theory and pcb assembly.

The Massachusetts Institute of Technology just announced the first course offering in their new online classes program. Great news, it’s an analog design course which is right up our alley. The prototype session will be 6.002: Circuits and Electronics.
If you’re a fan of our links posts you may remember hearing about the MITx program a month ago. After seeing the popularity of the Stanford program MIT is throwing their hat into the ring too. So what is this all about? How does it work and what will you learn? There’s bits of information all over the place. We recommend reading the news link at the top of this feature first. Next you should wade through the 6.002x FAQ and if you’re still interested there’s a big maroon enrollment button at the bottom of the course summary page.
Whew, that’s a lot of links. Anyway, expect to spend 10 hours a week on the class; but it’s all free. Future offerings will be free as well, but MIT plans transition to a pay-for-certificate option: “students who complete the mastery requirement on MITx will be able to receive the credential for a modest fee.” If you still haven’t made up your mind take a gander at the promo clip after the jump.

They can put a man on the moon, but they can’t put a man in LEO
Yeah, we’re enraged by that headline. Anyway, NASA put up a whole bunch of projects and made them open source. From the looks of it, there’s plenty of cool stuff: genetic algorithm libs, toolkits for astrodynamics simulations (on the Goddard site), and this cool thing.
Nyan all the disks!
[brainsmoke], a hacker over at revspace, made an assembler version of nyan cat that can be placed on the bootloader of any disk. Just a reminder that you shouldn’t mount everything out there. We learned that lesson the week we discovered a penicillin allergy.
It’ll replace the Buffy poster.
[Anthony Clay] has been working on a set of EE posters that he’s putting up as a Kickstarter. They’re Ohm’s Law, resistor calculator, capacitance, and inductance posters that would look great above any workbench. He’s looking for ideas for other posters, so drop him a line and vote for the 7400 logic poster. All of them.
Ooooohhhh MIDI sampler
A while ago, we saw this neat MIDI Arduino shield. The Kickstarter reached its funding goal (there’s still time left!), but now [Keith] writes in to tell us that the AvecSynth library is platform independent. You could use this to record and play back MIDI messages. MIDI tape delay, anyone?
Open mind, not mouth.
With the success of the Stanford AI class last year, it looks like MIT is really getting their head into the game. Think of it this way: it’s MIT opencourseware that can lead to credentials. Now the only question is, ‘how do you prank a virtual campus?’
