This Week In Projects

Lots of projects happening this week:
Spent some quality time debugging an OmniTurn CNC lathe keyboard for Renascence Manufacturing Corporation, turned out to be a blown fuse preventing the board from fully powering on, despite the deceptive LEDs still lighting up under parasitic power through the serial IO pins.

Jon finished installing stepper motors and supports on the CNC router:

Charle was able to successfully drip feed the Anilam 1100M controller some complex gcode commands to create this face:



Dave now has a working keyboard prototype that will revolutionize the way piano is played!

Alex was able to save a donated giant LCD TV from the trash with a simple single wire jumper, the brightness driver IO pin wasn’t putting out a brightness signal to the backlight inverter driver, jumpering the 5V backlight on command to the brightness command gives us a working TV, abet without brightness adjustment:

Carol attempted to repair the dreaded iBook G3 graphics BGA chip without luck, we likely did not get the chip warm enough to reflow the solder but did learn how to use the hot air rework pencil:

Menards had these great wireless outlets on sale for $10, getting 3 wireless controlled outlets in a nice package is waiting for an Arduino hack into the remote; hence we bought 6 sets and will be offering a one time Arduino hacking class for the holidays next week!

Larry debugging a string parser for Arduinos:

Larry making the sale on why electric bicycles rock to Rob, I believe a parts order was in later that evening. . .

Alex was able to install an ultra energy efficient 1W white LED to light up our door for the early darkness and icy winter conditions so when you swing by and can see the door from 3 blocks away you can thank him 🙂

Scott was finally able to injection mold some gears out of milk jugs (you can see the remaining green detergent bottle from earlier tests):


More shelves were fabricated to handle our 15 member’s storage bins:


Scott was also able to generate and run code for lost foam casts that we’ll be pouring out of aluminum castings (thanks again Isthmus for the material!) to get our mini-foundry up and running:



Some Saturday night shoe hacking to fix a broken shoelace:

And we were able to help out some BioMedical Engineering students with their design project, Sparkfun’s easy to implement 4 digit LED display was not so easy to implement but we were able to get a 16×2 LCD sourced and running in short order, turning their nearly failed project into a success in hours!

The fume collection hood was finally hung, yielding significant floor space and once properly ducted, a great exhaust system for welding/cutting/grinding and painting:

Lastly, the electronics benches were finally finished off, resulting in some sweet electronics workspace in the back of the conference area:

Speaking of conference area, a partially finished table was found on Craigslist and is midway through staining/polyurethane, next up is finalizing the pipe configuration in the base and inlaying the glass panes, no hammering on this table!

And finally, a Harbor Freight item that didn’t require complete rework to make it useful:

Arduino Nights!

Tonight (12/1) and tomorrow (12/2) Sector67 will be hosting open Arduino nights, so bring in your stuck/unfinished/sick-of Arduino projects and get them finished off.  We’ll be providing comfortable seating, workbenches, soldering irons, friendly faces and warmth (/no snow) – you bring the rest!  Starts at ~6pm until whenever, call at 608-241-4605 if you’re wondering whether people are still out working.

Also feel free to bring out snacks/beverages/etc, we have a fridge/microwave/pizza oven.

Low Impact Small Housing

Interesting solution to urban living found on ChinaHush:

Egg House

The article outlines the high cost of living in Beijing coupled with the lack of housing available in the downtown – leading to unsatisfactory living at the edges of the mega-city that result in daily long dirty commutes by bus. The solution of course is a single “room” house on wheels that provides shelter and a little bit of storage, and to then rely on locally available showers and services like food and laundry, thus removing the need for a large home while maximizing interaction with the surrounding community.

Salman Khan talks about Khan Academy

If you’ve never visited, now would be the time to stop over at Khan Academy and learn all the things you’ve never learned. The core concept is to provide education at your pace online for free. The video below discusses Khan’s vision for the website:

This project fits in great with our fiscal sponsor The School Factory‘s vision of a level playing field for education and changing the way education works.

Sparkfun Free Day! – January 13th

Yes, you heard that correctly, Sparkfun will be giving away merchandise for free on January 13th, just before their servers implode, light on fire, and melt down like they did last year.

You’ll want to head on over to their website for the fine print, but I assure you there isn’t much. 🙂

Injection Molder in Action!

I returned from The Netherlands on Sunday to find Scott hard at work on his next generation injection molding machine. This version operates in the drill press to to give better control and consistency to the injection operation, and has a much larger plastic volume.

Scott used the CNC mill (on its maiden aluminum eating operation) to generate two mold halves of a gear reduction (or multiplier), being cut in half here:

Thanks to Isthmus Engineering for their “scrap” aluminum!  You can see the 2 bosses surrounding the gears, which fit together perfectly.  The gears sit in the center, and the sprue for the injection at the left side of the large gear.

The first step is to load the heated chamber with plastic bits from laundry detergent containers (this would be called UPcycling, not REcycling, and certainly not DOWNcycling like most of your “recycled” goods end up), then to preheat the mold.  You can see the results of the first injection attempt at the near edge of the press table, everything worked perfectly but we didn’t have enough plastic loaded up:

Next is to lean hard on the press handle and hope everything stays together:

Just after this picture the single C-clamp squeezed sideways and let plastic squish out from between the mold halves, hence the flash:

Pinion gear half:

What’s great here is you can see perfectly formed edges on the teeth/gears with great surface finish.  The black/gray spots are from us being too lazy to clean out the machining chips from the mold before injecting (in a hurry).  Looking at the spur gear half you can see if we trim the flashing off the part we’ll actually have a great gear!  What else is fun is putting anything metal (or plastic) through the center of the mold, you can put a keyway in, threads, a flat, etc per application.

Using our earlier partial gear, we can see a very promising mesh:

Project is on hold until after the holiday, but look for more updates soon!

Open Source Farm Blog / Wiki

Very cool open source farm, they detail equipment/resources/rough fabrication techniques that allow them to create a plasma cutting table, universal hydraulic power supply, skid-steer, etc

The School Factory : Space Federation Video

James Carlson (Founder of The School Factory and Milwaukee’s Bucketworks) posted a great explanation of the Space Federation and what The School Factory is:

I’m enjoying great food and talks in The Netherlands which is why we’re a little slow on updates this week! I’m hoping to visit a few spaces in Amsterdam on the way back to the airport Saturday 🙂

Updates! – MSN Article, Arduinos in stock, Arduino class tonight

Couple of interesting things to report:

MSN has a surprisingly well written and interesting summary of hackerspaces throughout the country.

Our reseller order from Adafruit Industries has arrived, meaning that we have (and will continue to stock) Arduino Unos.  In addition we have a protoboard shield, a trip glasses kit, and a Boarduino kit.  Prices are Adafruit standard pricing +$2 (Uno is $32, etc).

We’ll be hosting our first ever official class out at S67 tonight, we’ll put up pictures soon.  If you haven’t taken a look, we have an ever growing list of classes on the classes page, if you have something you’d like to learn about (or to teach) let us know by e-mail/etc.
