Builder’s Night Out – October 6th

After weeks of revisions and sitting idle, the “Podium” project was completed last night.  Constructed from a tri-fold photo booth enclosure and a rolling base, the Podium holds a binder full of Guest Release Forms to introduce visitors to our space while also performing a very practical and necessary legal responsibility.

In addition to the variety of projects that were being worked on last night, Shane and Brant rewired Chris H.’s “American Horseshoes” game cabinet and reconnected the speaker.  After a few rounds, we understand why it had been disconnected.  It’s definitely a bar game.  Regardless, it will make a great addition to the Workshop.

Junk Bot 1.0 lives!

 

Greetings! 

   Hi, I’m David and this is my first post on the Milwaukee Makerspace site. I’m a video producer by trade, so you’ll be soon seeing some videos from some of my projects, however if you’re on the site you might have already seen some of my work. In late March I put together some videos of the Makers talking about what they make and what they think the Milwaukee Makerspace is. 
   Anyway, I didn’t even know what a Makerspace was myself till my friend Matt wrote me an e-mail and said, “If you want to walk the walk, come down to the Milwaukee Makerspace.” Needless to say I had no idea what that meant, but as soon as I stepped foot in our beautiful space with the warm welcoming logo above the hangar, I figured it out pretty quickly. 
   I have never done any robotics or electronics in my life, but seeing what the makers was up to inspired me. I picked up a soldering iron and started small. I’m the kind of Maker that works their way up to the big projects. Initially my ideas for projects mostly relate to my profession of video production. I would like to make a low to the ground camera platform, for wide angle shots, and a flying rig for some limited ariels. One thing at a time though, first I have to make something that works.

Introducing… JunkBot 1.0!!!

JunkBot 1.0 is my first attempt at what I want for a ground based camera platform. It sorta kinda does everything i want it to, but isn’t very robust. It’s functions are:

– Moves forward, back, turns using tank style steering
– Has a pan tilt camera mount
– Can wirelessly transmit video from the bot to a ground station
– Is controlled via a standard RC controller
– Falls apart slowly after about 15 feet of travel

My build process was:

1. Find plastic platform and half project box at the Makerspace “Hack Rack”
2. Get 2 continuous rotation servos & wheels. (Parallax servos sold at Adafruit)
3. Get an RC controller I am happy with (Futaba 7C 2.4ghz)
4. Get 2 servos and mounts for the pan tilt functions of the camera mount
5. Get 900mhz wireless video transmitter (RangeVideo)
6. Make front tire out of foam and a coat hanger
7. Strapped it all together with Velcro (TM).

I used my GoPro camera because it’s small, light, and gets 

the job done. I really love those cameras.

I got to show JunkBot 1.0 at the Makerspace Grand Opening and I think it went rather well. Next up I need to make some improvements:

– Better platform
– Better pan tilt
– Better propulsion
– Make it out of quality materials
– Add in some autonomous functions

But, you have to start somewhere, right? So we’ll see how this all goes. JunkBot 2.0 here I come!

Thanks for reading,
David
