Machining Brass & More Electronics - OpenSCAD Workshop

It has been a while since my last post.  I have been rather busy this quarter with my senior capstone project (Stay tuned for that later...)  One of the things that I have been working on for another class is machining a power cylinder for a Sterling engine.  I changed the design to include machined letters.

I have also been playing around with a number of electronics things.  I bought an Open Bench Logic Sniffer which is very cool but comes without a case.   I found a design for one on Thingiverse but wanted to have cutouts for the optional headers so I modified it (here).
 



I also bought a Freeduino which is a very nice little thru-hole Arduino clone kit.  It was very easy to assemble.





I wanted a case for it as well so I designed and printed one.



This case will also be one of my examples at the OpenSCAD workshop I am teaching at Metrix Create: Space on Sunday, March 27 from 2-4pm.

Scanner Teardowns

I had two old scanners that I have had floating around for awhile and finally decided to tear apart and salvage the parts that could be useful.  Here are a few pictures (more here & here):

Power supply

Stepper and LEDs

Product Overview

Voltage to drive cold cathode

Stepper driver chip ULN2003AN

At a minimum I was able to salvage the following (there is more I may be able to de-solder):
2 - 12v steppers with gears, belts, etc...
3 - smooth guide rods (with bushings)
1 - 12v, 1.5A wall adapter
1 - 26v, 5v, +12v, -12v supply (I don't know the amps...)
1 - White cold cathode tube with control board
1 - RGB cold cathode tube set with control board
2 - FFC with connectors (will have to de-solder the connectors)
2 pieces of glass
Assorted mirrors
Assorted LEDs, switches, etc...

Arduino and an Inkjet Cartridge

I have started experimenting with Arduinos and electronics.  This involved buying a Arduino Mega, breadboard wires, PCBs, and some other assorted goodies.

Breadboard wires
Assorted PCBs from BatchPCB
Thrift store power supply finds

I have managed to get my Arduino to talk to a inkjet cartridge and spray ink.

This is going to be a part of my senior project at the UW, more on that later :-)

Snow!!!

Monday we had snow at the UW.  I was 20 minutes late to class and then after lab it took almost three hours to get home....



Some fellow students were even making a snowman. :-)



This turned into two snow days on Tuesday and Wednesday...

Movember

I am participating in Movember to help raise awareness of men's health issues.  I have been growing a Moustache since the first of November and have been posting daily picture updates on my MoSpace Page.

I also have a collection of items on etsy that I am selling to help support Movember.  During the month of November I am donating 100% of the sale price of all of these items to the Movember Foundation.  Some of these items were 3D printed on Willow.

An Update on Things...

It has been a while since I last posted here.  After my brothers wedding I took some time to get caught up on things.  I did not come here and post about them, so here is what the rest of my summer brought.

  • I started printing Mendel parts again and now have a full set on eBay.
  • I opened an etsy shop and have things ranging from wood-burned Celtic knots to 3D printed Moai and hand painted Bullroarers.
  • I started websites for myself (NicholasCLewis.com & RepRapBreeding.com) and my wife (SunnysideCakes.com & GoatvillePygmies.com).
  • I setup a demo with a local distributor of a uPrint at work.  I think we may buy one for prototyping, tooling, and mock-ups.
  • School started and it is a little lighter quarter than I have been having.  (I also turned in my paperwork for my math minor).
I think that is about it for now.  I will try not to wait so long before posting again. :-)
