Catapult Competition

trebuchet

catapult

We like to build things.
We like to build things that throw things.
We like to build things that throw things farther than someone else’s thing.

This your chance to show us what you can build as well as win some prizes
if your thing throws farther than anyone else’s thing!

Here are the rules:

  • Design must be mechanical in nature
  • Catapult must fit inside a 2′ x 2′ x 3′ box
    • Will be measured in an “un-primed” state
    • Any priming accessories must be included in this measuring
  • Scoring is by distance
    • First hit counts
    • Will have 3 attempts
  • Tennis balls will be used as ammunition
    • To be provided by PaxSpace
  • Teams must be no larger than 2 people
    • Competition is open to non-members!!!
    • At least one member of a team must be a PaxSpace Member
      if the Space’s facilities are to be used in the construction of the catapult
      (Great chance to get to know how to use our new CNC Router)

Teams must register to enter.
The competition will be held on July 13th during our Summer Open House.
Registration will open up May 13th and close June 13th.
Check out our blog at that time for how to register.

There will be prizes for the top 2 teams.

CNC Router is working!!!!

cnc smile

This is the first real object that has been cut by our CNC Router!

The PaxSpace CNC Router works, but it is not ready for member use yet. The following tasks need to completed:

  • The electrical box layout and wiring still needs to be designed and finished.  Most of the parts are in hand.
  • The control computer/keyboard stand needs to be designed and built.
    Shout-out and Bravo Zulu to Matt Virts for getting the touch screen working.
  • More permanent legs still need to be designed and built.
    Something simple about 32″ high using 2x4s with cross bracing
  • The MDF spoilboard needs to be cut to size and mounted.
  • A work mounting and clamping system needs to be designed and built.

Most Important:  There are many possible work-flows for using the CNC router.  We need to figure out what combination of tools and programs we want to use to later teach to our membership. This is fairly new to just about everybody in the space.

I would like to get more members participation in these final steps. Please come out and support the final build-up.

Lets plan a CNC Router meeting and demo for Thursday at 6PM from 7:30 to 9PM.  Use the CNC Router forum for any questions or comments.

Cool KickStarter, Chip Sized Arduino with OLED Display

MicroView Arduino

I recently found this cool KickStarter, It is an chip sized Arduino with a built-in OLED display.
The “microview” will be manufactured by SparkFun right here in the USA!!!

It is only $45 by itself or $55 with the USB Programmer.
Compare that to just an Arduino UNO at ~$28. Quite the deal!
Just 13 days left to go with delivery expected August 2014.

Check it out!

New Class – PCB Design and Printing

PaxSpace is excited to announce the addition of a PCB Design and Printing class to our schedule. The class is being taught by Zach Long, a PaxSpace member, who has been designing and creating integrated circuits and printed circuit boards throughout college and in his free time.

This class is mainly geared towards people familiar with bread-boarding and electronics who are looking to make their projects more permanent. The course is meant to be a crash course to get you started as there is much to learn in both areas. The first part of the course can be taught with one of two software choices. The first of which is EAGLE and the second KICAD. Here the participants will design a basic circuit consisting of through hole components. The second part of the class will be actually printing and etching your board. At the end of the class you will have made your own PCB that is ready for components.

The first installment of this class is scheduled for April 18th from 6:30 pm – 8:00 pm. Please click here to register for the class as space is limited.
