Science! Is Afoot

July 16th, 2014 by danbackslide

A while back I was contacted by Bede Willenbring, a research chemist at H.B. Fuller. He was getting some new equipment for their lab, and wondered if we were interested in getting a scanning electron microscope.

A Scanning. Electron. Microscope!

Obviously the correct answer in this situation is “Yes sir, please, sir!” Arrangements were made, and just a few hours ago we rolled a Cambridge Stereoscan 260 into its new home.

As I write this, McSteve is working on getting it hooked up to the 20-amp circuit in the classroom. We’re hoping that by later this evening we can get Cammie (for that is her name) powered up. After that? No idea, really. If you know how a SEM works, why not swing by? (Mr Willenbring has offered to give us a hand with it once we have power, but more brains are always better!)

I want to extend a huge thank you to Mr Willenbring and H.B. Fuller for making this possible. For great science!

Shapeoko: It’s alive!

June 27th, 2014 by danbackslide

Thanks to the folks who helped put our Shapeoko CNC together. Last Saturday evening, Mark and Pete helped me assemble the hardware. Then on Wednesday, Bill put the belts on, and Jim and Adam ran the wiring and hooked up the electronics. We ran the “Hello World” test with a pencil jury-rigged in place of the rotary tool. Success!

Now it’s time to dial it in and start getting some experience on it. CNC people, let me know if you want to play with it. Not a CNC person? Hang tight while the Shapeoko gets calibrated, then we’ll start turning other loose on it.

Time to make a Shapeoko!

shapeoko-kitIf you haven’t heard yet, the kind folks at Inventables have donated a Shapeoko desktop CNC kit to Twin Cities Maker. The kit arrived Thursday afternoon — time to put it together!

We’ll be starting out at 5pm tomorrow, Saturday 6/21. If you’re interested in helping out, please come on by. There will be something for everyone to do. Of course if you just want to hang out, that’s cool too. The more the merrier!

The final push to installation: volunteers welcome!

Hello and thanks for reading my blog!

This is me testing out my bench at the half-way point.

This is me testing out my bench at the half-way point.

At the time of my last posting I had only 2 sections of my Musical PVC Bench completed.  Again, many thanks to the TC Makers volunteers who helped me get to that point!

Here are all 6 sections lined up as they will be when bolted together.

Here are all 6 sections lined up as they will be when bolted together.

Every section is now welded together.  You can see in the attached photo that I still have some sanding to do (mostly of excess PVC cement) and that it will need to be painted in order to hide markings and solvent stains as well as to protect it from the sun.

My mentor, Jantje Visscher, tests out the full bench.

Anyone interested in volunteering to help with final steps will be welcomed. Remaining steps are sanding, spray painting, finishing paddles, attaching paddles, welding/cutting metal anchors & bolting sections together by Sept 22.

Big. Frikkin’. Laser.

September 13th, 2013 by danbackslide

laserThis is Cathy, our brand new Full Spectrum laser cutter. She has a 90-watt laser tube and a 24″ by 36″ cutting bed.

Jude has spent the last week and a half or so getting Cathy’s new home ready — she will be living in the former shop office, next to the metal shop. Inevitably, what was supposed to be a quick room update turned into a major operation as various interesting architectural “features” were discovered…

I and a few others have spent the last week or so getting the laser set up and running it through its paces. I gotta say, this is a wonderful machine, and I’m really looking forward to getting classes going! We are targeting the first week of October for the start of basic training classes, which will just cover safety and basic operation. Riley will also be working up a more detailed class which will feature Deep Knowledge.

Some answers to questions I’m sure you have:

  • You need to be a member to use the laser cutter. (See, one more reason to be a member!)
  • You will need to take either the basic class, or Riley’s Deep Knowledge class, before using the laser. Yes, even if you’ve used laser cutters in the past.
  • We’ll be charging $5 per hour of runtime. The laser tube will burn out eventually, and a replacement is not exactly cheap, so we need to bank up the cash.

Watch this space for class info! Or keep an eye out for the TCMaker Newsletter in your email. What, you haven’t been getting the newsletter? Look over to the right, there’s a signup form there.
