tv: 3d Printable Rubber Band Gun



Designing a printable rubber band gun has always been on my bucket list. I used the holiday season as an excuse to finally do it. You have to fight consumerism somehow, right? And what better way to fight it than to print rubber band guns for your relatives.

Of course I'm releasing this to the community. Here are the files you will need to print one for yourself:

tv: The Scratch Flight



Building a remote controlled plane from scratch has always been at the top of my bucket list. This week I popped it off the stack, built, and flew! You could argue what I did isn't really flying. I might agree with you. Ha. But it's a start. I just need LOTS of practice!

I built this plane out of dollar tree foam and packing tape by following the masterful tutorials of Experimental Airlines.

tv: Measuring Wire Flexibility

Season 3 : Ep. 10 | 10:30



I noticed a trend in the comments from the last video. I got a lot of comments about using a smaller gauge wire. In this episode I test the flexibility of 30 gauge, 26 gauge, and 26 gauge shielded wire. Thanks for all the feedback from the last episode! In the next episode I'll dive deeper into that feedback.

tv: A Problem of Flexibility

Season 3 : Ep. 9 | 3:13



I need your help. I'm stuck! I need a way to receive information from the DogBot foot without restricting it's movement. Any ideas? Please leave a comment if you have any ideas!

Here are the background videos leading up to this one:

tv: Servo Animation

Season 3 : Ep. 6 | 4:18



In this episode we plug in our hacked servo. This hack allows us to not only tell the servo what to do, but also record movement. One application of this is to record a manual motion while the servo is disabled, then enable the servo and play the motion back! - Season 3 : Ep. 6 For more episodes, visit: http://tv.onshoulders.org

Test Bed Details:
Hardware - Boarduino
Arduino Code - https://gist.github.com/4241105
Wiring - White wire to a0, with voltage divider
Need more test bed details? Just ask.


I'd like to thank jes1510 for his excellent work getting me started with servo hacking: http://forums.trossenrobotics.com/tutorials/how-to-diy-128/get-position-feedback-from-a-standard-hobby-servo-3279/

tv: Dogbot Learns to Feel, Part 2

Season 2 : Ep. 5 | 12:32



This episode is the fifth in a series of episodes on creating a dog robot. This episode looks at a primitive pressure sensor design that I printed on my 3d printer. Is it enough to help DogBot feel its environment?
