DelFly2 and DelFly micro

filed under: robots hacks

The video you see above is the on board footage of the DelFly2 autonomous ornithopoter robot. Weighing 16 grams, it carries a small camera and can provide a live feed. If you’re amazed at the tiny size and weight of the DelFly2, check out the DelFly micro, video after the break, that weighs 3 grams. Remember when we thought 17 grams was small for an ornithopter?

All processing for the DelFly2 is done at a base station and transmitted to the flying bot to keep the weight down. The team also had to create their own brushless motor that runs at 60% efficiency and weighs only 1.6 grams. The 130mAh battery can sustain 15 minutes of horizontal flight or 8 minutes of hovering.

TOBI the tool bot

[TheGrue] has put together this great writeup on how he built TOBI, the tool carrying robot. Inspired by a story he read about a robot that could follow people around, using heat sensors, he decided he wanted to do something similar. His robot would carry his tools, in this case, the tools of an IT professional. Not only would it carry his tools, but surely it would give him credit as a techno-guru to have a scratch built robot following him around.

His build process is documented quite well. He approached this in a fashion where he set several iterations. Each step would add a feature and carry the old features forward. It looks as if he’s currently working on step 3, which means that the chassis has already been built, the drive train is working, it can be remote controlled, and now has some level of autonomy thanks to a propeller controller. Up next are some range finders and an assortment of other sensors so that TOBI won’t drive off any steps, or into any walls.

Open source engraving

[Scott] wanted to do some v-carving with a CNC router, but couldn’t find software to generate GCode that didn’t cost hundreds of dollars. He ended up doing the sensible thing and wrote his own that will generate tool paths from CXF fonts. We’ll be bookmarking this for when our router project is done.

Improving Genesis sound output

Dissatisfied with the sound output on his Sega Genesis, [Drakon] installed a few mods into his console. How much could it really affect the sound? Listen to the video. The changeover happens at 0:50. Impressive. Now if only the chiptune scene would get into Segas.

Yes, we did, and now we’re seeding

Here’s an alternative to Thingiverse: The Pirate Bay has a new category for 3D-printable objects. The best file so far? A 1970 Chevelle. US Copyright law does not protect (most) physical objects, so it’s not illegal. Honestly, we can’t wait for somebody to take this to the courts; It’s sure to be an interesting case. Somebody upload a ship hull design and give the EFF a buzz.

Just be glad it’s not a QFN

[Mikey] was pulling a PDIP ATMega8 out of a socket with pliers and a screwdriver and broke the RESET pin. Ouch. He fixed it by soldering on a lead from a resistor. We’ve all done this before, but [Mikey]‘s results look really good. Here’s the gallery.

This might be fake

If you want a second analog stick for your 3DS, you could wait a month and buy a Circle Pad Pro, or install a PSP analog stick. We’re not sure how this would work – the Circle Pad Pro works over IR, and we’re not seeing an IR transmitter on this build. Here’s the source if anyone wants to give this a shot.

Wii Nunchuk controlled Monotron

Adding a bit of motion control to your music synthesizer turns out to be pretty easy. Here’s an example of a Wii Nunchuk used to control a Monotron. [Thanks John]

Hackers on the Moon and other space related goals

Yep apparently a non-government backed expedition to the moon is in the works. But you’ve got to walk before you can crawl and one of the first parts of the process is to launch a hackerspace-backed satellite network called the Hackerspace Global Grid. Check out this interview with one of the initiative’s founders [Hadez]. [Thanks MS3FGX]

Laser pointers and frosted glass

We were under the impression that a laser show required finely calibrated hardware. But [Jas Strong] proves us wrong by making pretty colors with laser pointers and slowly rotating glass. [Thanks Mike]

MSP430 Twitter Ticker

[Matt] built a Twitter ticker using the TI Launchpad. It works on an LED matrix or OLED display along with a Python script which handles the API.

Android floppy drive hack

[Pedro] shows us how he reads floppy disks with his Android tablet. The hardware includes a docking station to add a USB port to the tablet, as well as a hub and USB floppy drive. On the software side of things an Android port of DOSbox does the rest.

LED Dog Collar

LEDs make everything better, right? What about your dog? [Ken] tries it out on one of his frisky dogs who loves to run whenever she gets out with a LED dog collar. It’s an off the shelf dog collar sporting 5 blue LEDs, and is powered by an attiny2313 micro controller, which makes adding / changing light sequences quick, easy, and also allows for future upgrades. Small PCB’s are made and to help keep minor amounts of the wild from frying. the electronics parts are encased in hot glue, and the whole thing is powered by 3 AAA batteries.

While it’s an early test of the device, and there is more to come, like an automatic trigger as [Sunshine] bolts for the door, but it seems like a great help while chasing after a runaway dog in the dark.

Join us after the break for a quick video.
