Exploring the parts bin

Workshop88 has been the recipient of lots of donated electronic parts. An effort of an hour a week or so over the last several months to sort through them is starting to show some results, so some random jottings on what’s back in the lab seem useful.
An awful lot of resistors are back there. If anyone needs virtually any value of 1/8th watt thru hole resistor you can probably find it, along with a pretty full set of surface mount resistors. There are also some larger wattage resistors, though they’re not as sorted out.
The thru hole or breadboard LED supply is also well stocked. Many colors and several sizes are back there.
One useful looking find last night was a half dozen PIC processors, PIC16C745. These have built in low speed USB, so they could be used in any project that needs a USB port to control or monitor something else. While not the latest part, at least they’re from this millennium.
This is just the tip of the iceberg on what’s available in the electronics bins for members. While most of what’s there is far from leading edge, for breadboarding purposes it’s ideal. One project that Jim and I have discussed is to have a simple PCB manufacture setup right in the room, so that an idea could go from concept to populated board in a couple of hours.

Volunteering for Quest Academy

The Quest Academy in Palatine is opening an “Innovation Center” next year that will include a 3D printer for the kids to use. Vinnie Vrotny, director of academic technology, asked Workshop88 to bring a couple 3D printers to a benefit event last evening. Proceeds of the event will help fund the center.
I brought the MakerBot Cupcake up to Hoffman Estates. I’d pictured a junior high gym as a venue – in fact the benefit was at a pretty upscale banquet hall. Initially I thought that jeans and hiking boots might not be suitable among the tuxedos and gowns, but I think our demo was very successful. Lots of people stopped for lengthy conversations, and were quite interested in the tech. It didn’t hurt that the printers were right next to the open bar.
We should keep some open contacts with the school, as some of our aims match well with theirs.

Giving back to the Community

As a maker space, we always love sharing knowledge! Recently a member of Workshop 88 started helping out a local group called the Hacker Scouts. The Hacker Scouts are a group of young kids who meet every two weeks to learn something new about science and technology. They reached out to Workshop 88 members to help teach. I wanted to share this article with you to help you get an idea of the amazing things they do. They are a great group of people with a great mission, and I encourage you to get involved! Simply send email the main organizer: Elaine Luther at elaineluther@chicagogiftedcommunity.org!

Public meeting notes – 2/14/2013

Last night was a great turnout for the Public Meeting at Workshop 88. Over a dozen makers came out to work on various projects and learn new things at the space.

Our friend Tom M from the Fox Valley ASME chapter came out and had a small part for his project printed on the 3D printer:

Proper prepping for 3D printing

We’ve been doing a lot of 3D printing recently at Workshop 88.  Many times we just download models from Thingiverse, but more and more we are designing our own models.

Using Sketchup is one way that models can be created, but sometimes when you print a complicated model as designed in Sketchup, there are pieces of the model which are missing.

Enter: CADspan.

There is a tutorial available for this Sketchup plugin which allows you to find holes or reversed faces in your models. Recently, there was a model designed which failed to print correctly. When using the CADspan plugin, it was discovered that many of the faces were reversed:

The red faces are the ones that needed to be corrected. A few right-clicks later and the model was fixed:Screen Shot 2013-02-14 at 1.14.42 PMWe’d love to know your tips and tricks for getting better prints from your own designs. Let us know!
