Hey everyone.

I am working on putting together a soldering workshop and I need feedback from everyone. Below, I have listed the date/time I am proposing as well as a choice of soldering kits with links. Please give me any feedback you have. I will be  able to offer multiple classes at different times, but for now, I want to run a single class to see how my lesson plan works. Once I get a lesson plan complete, we will be able to offer a class like this as often as requested. Once I get enough feedback, I will publish/announce a signup sheet for the class. Xerocraft members will take priority.

Class Info
Proposed Date: Oct 17th @ 7pm in the main classroom.
Number of stations per class: 6 preferred/10 max
Signup Requirements: RSVP with deposit takes priority on signup. Deposit will be cost of kits/materials so I can order kits.
Topics Covered: The class will cover the basics of soldering including use/care of a soldering station, basic soldering techniques, desoldering methods, and solder practice by building a small electronic kit that the participant gets to keep.
Kit pricing: Each kit will cost $10. We are getting discounted pricing since I will be ordering in bulk and for educational use. Prices listed below cover kit cost, materials (flux, solder, ect...), and small donation to Xerocraft.

Project Ideas / Welding Classes - 240V outlets
« on: September 10, 2013, 04:59:37 pm »
Hey

As part of starting to offer welding again, we need to start figuring out what type of 240V outlets need to get installed. I know that my MIG needs a NEMA 6-50 outlet, our Buzz Box may be able to use a 6-50 and I believe Steve needs an outlet with the two phases plus neutral. We need to figure out where to install the outlets (outside perhaps in weatherproof box?) and what types are required. What type of parts do we have in stock, what do we need to get, and what outlets need to get installed? Lets start planning.

Completed Projects / Cardboard Party Planning Meeting
« on: September 09, 2013, 11:44:28 pm »
Hey Everyone

On the 28th, there will be the cardboard ball happening in the north space. This is a party where everyone shows up in cardboard costumes and/or with cardboard artwork. As discussed in today's steering meeting, I would like to hold a meeting on this Saturday at 1pm in the multipurpose room of Xerocraft to start design/crafting process so that Xerocraft can be awesome at the party. Who would like to help with this? Please save up any cardboard you may have for this if you want to be involved. Additionally, I have 2 robot platforms that can be used for cardboard robots (perhaps 3 if steve lets us use Sparks) as well as lots of spare robot parts. I would like to make one platform a Dalek, and the other platform (or 2) are available for other ideas. So, whos in? Post ideas here.

Off-Topic / Trampolines in Tucson!

Apparently a warehouse full of trampolines has opened in Tucson.

Xerocraft Trampoline Day anyone? We could all wear Xerocraft shirts.

Project Ideas / Two hub motor wheels, drivble sofa anyone?
« on: October 28, 2012, 06:47:39 pm »
Anyone have any interesting ideas for these wheels I have? Perhaps attach them to an easy chair or a large work table? They are hub motor wheels that are rated at 180W. The one in the pictures is the nicer of the two units I have. The other wheel has a flat tread to it and does not have the electromechanical break (only a manual break). Both wheels are removable from the swivel bracket and could easily be mounted in a fixed location or frame as long as mounting points were provided for the axle on each side.



The nicer wheel of two I have. It rotates 180 degrees on its own bearings and has a nice bolt pattern for easy mounting to a front facing, vertical surface. This wheel has a built in electromechanical break. Additionally, it runs at 12V and is a 180W motor. This used to be in a mobility scooter for a grocery store. While underpowered compared to the robots I am building, it should haul a person or two around just fine on flat ground. It only moves at slightly better than walking speed.


Top of the wheel module. It has a nice key slot for a handle or other system used for controlling direction. There is a hole in to the slot that is threaded for a screw to hold the keyed steering connection from slipping out.

In Progress / Large Robot V2 (No Name Yet)
« on: October 27, 2012, 05:16:05 pm »
So, here is where I will keep my project log for the robot I am building. Currently, it has no name. Any ideas for names, or any ideas for the design?

To start, here is the build log from my summer work.

This is where I built the lower frame over the summer in LA at my parents house.



This is the rear section of the lower frame with the gearbox/motor unit that was originally made for a mobility scooter. I got the motor at Apex Electronics in LA over the summer. Originally, I was hoping to make the new robot design splittable so the center section could be replaceable. This would allow the robot to be a long robot for hauling, or a short robot for indoor navigation, or any other special design we may need, all based on which center was installed. Given the problems this was giving me, I opted to move to a more conventional single frame robot but the two sections were already built separate, so I had to rejoin the two sections and weld them together again. To do this, I used a smaller rod down the center to provide strength at the weld point. As a compromise to provide a multi-use platform, I opted to design a "L" bar upper deck (the current design) that would allow plywood "shields" to be swapped out with different payloads.


This is the jig my Dad and I used to weld the two sections together and keep them straight.


The final lower frame with wheels installed.


This concludes the work I did over the summer. Next, I will show the work I did today (10/27/2012) on merging the lower frame to the upper "L" frame I made two weeks ago.
