Starting at 7 PM on Monday, September 12, Hive76 will be starting a new ongoing monthly workshop focusing solely on the wonderful world of microcontrollers.
“What’s a microcontroller,” you ask? Let’s take a quick glance at the Wikipedia page!
“Yeah, so?? Why should I care?”
“What if I’m familiar with microcontrollers, and I’m just looking for a place to talk shop, jump-start a stalled project, or help other folks learn a thing or two?”
Great! Now that you’re coming, what can you expect?
You can expect to be welcomed into a friendly environment and you are encouraged to bring your ideas, aspirations, projects, and most importantly, your questions! Individual projects, group projects, build challenges, basic skill instruction, hardware buying guidance, and experts on hand! I would like to emphasize that this workshop is open to complete beginners. No prior experience with electronics OR programming needed! We’ve all got to start somewhere!
PIC, Basic Stamp, MSP430, Arduino, etc… no microcontrollers will be turned away! This is an all-inclusive, open workshop to promote learning!
The Fine Print: Materials will be available for use within the space and a limited amount of hardware will be available for purchase. If you’ve got a laptop or netbook handy, please bring it along. Instruction and guidance will be available free of charge!
(Donations are always appreciated)
This workshop is brought to you by: KBI, Inc.
In collaboration with NextFabStudio, we are offering a state-of-the-art and upgraded RepRap printer kit and accompanying 3-day Build Workshop from August 26th-28th. The class cost is $998 ($1,200 for non-members) and includes EVERYTHING you need to get up and running, and more importantly, a fully calibrated and fine-tuned robot.
Check out the time-lapse video below from our first class in Baltimore where we got 10 printers up and running in 3 days.
We’ll help you and a friend or two to build your very own open-source RepRap 3D printer, which has more than 4x(!!) the build volume of it’s closest competitor, the MakerBot Thing-o-Matic. Note that you will save $202 off the class if you’re a member of Hive76 or NextFab Studio. Total class cost for members is only $998. This is a crazy cheap deal! You can’t even buy a MakerBot for that price, let alone learn how to assemble it and fine tune it correctly in just a weekend.
There’s lots of additional bells and whistles on this bot that you won’t find anywhere else: custom machined aluminum motor couplers, linear bearings, the latest RAMPS electronics, and much more!

A few months ago Enrique Muyshondt (President of DesktopFab, aka Endeavour on IRC) gave us a set of Sells Mendel parts that he had cast for our work on various research projects at UPenn and here at Hive76. We slowly assembled it and got it running, and thanks to this past weekend’s RepRap World Tour stop in Baltimore, we have it running! In addition to 3D printing like a champ, we’re now using it to work on the firmware and customize printing scripts for tissue engineering research. We are grateful for the support!
The parts are cold cast bronze, this means Enrique painted several layers of bronze powder into his molds and then cast them with resin. What came out were the brown parts you see in the pictures and video below.
This 3D printer rocks. The RepRap 3D printing project still has a lot of rough edges, but that’s why we love it. We’ll have BronzeBot on exhibit at the next RepRapWorldTour in Baltimore, and then back in Philly in August to do it again.
Adam, Peejay, Justin, and I met Saturday to see just how fµ¢%ed our old enterprise Stratasys FDM 2000 is.
To catchup: we got a Stratasys FDM2000 from a garage sale for a song and it came with lots of unknowns. It has sat in our hackerspace and moved with us for almost 2 years.
These things are in good order:
Problems that we found:
Great news! We have tons of consumables! Spools and spools of ABS, support material, some cool looking elastomer and foam for the build platform.
Apple gave everyone a new shiny thing to talk about today and I will not be left out of the discussion! Apple’s refreshed MacBook Pro contains a new Intel chipset Core i5 and i7, codenamed Sandy Bridge. One lovely “feature” of this new processor is the Intel Insider built in to every Core i chip. This feature unlocks HD content playback on your machine for a limited time. Intel denies that this is DRM, and rightly so. DRM has been a hated buzzword among consumers and Apple alike. (No customer ever asks for more restrictions.) What Intel Insider has is worse: trusted computing, and for the worst reason too. It seems Hollywood has asked our biggest processor manufacturer to protect their business model with a feature that prevents streaming video from being recorded. Doesn’t that sound kind of unhinged?
Trusted computing is a hardware solution to the problem of trust. It has some noble goals. Your computer today may be exploited in some invisible way, but a trusted computing platform would verify all the code through it’s own protected hardware before allowing any software to run at all. The only way around this is to saw away at a encryption chip epoxied onto your motherboard. So, no malware is a good thing, right? That sounds fine until the keys to the computer are taken out of your hands and given to Hollywood/Intel/Apple/anyone-else because you, a de-facto pirate, can’t be trusted. Just wait until your repressive authorities request control of your shiny MacBook from Apple, and Apple acquiesces.
Add to that the recent processor recall, and it’s a scary time to buy new Mac hardware. Isn’t there room enough in the smart consumer market for some Linux hardware that Just Works? Today I’m one step closer to kicking my addiction for sandblasted aluminum and high-strength alkali-aluminosilicate glass.
Of course, I got all my opinions from the story 0wnz0red written Cory Doctorow for Salon.
We are proud, tonight, to continue this tradition. We would like to congratulate long time Hive76 member Adam Kaufman, also know as Adam on IRC, for joining the ranks of our elite.
Take a bow Adam. You’ve earned it.
PLA bushing sliding on precision ground 8 mm rods is actually quite smooth movement. I don’t think it can go as fast as the original Sells Mendel (which was ball bearings sliding over the rods), but it’s only half the printed parts and the z-axis is much smoother motion too. I will try oiling or greasing the bushings to try to get smoother and faster motion without losing steps. So definitely some tradeoffs but overall a super awesome bot. The Prusa is also fully parametric and entirely made from OpenSCAD. All sources are available on github FTW.
As this is the first bot I built that I actually own, I named this awesometown after my HS science teacher, Mr. Sloate, who really got me into Biology and now, robotics for Biology.
What will we print next?

We’ll be using the Ponoko gift certificate to design a housing for the electronics and make it more kit-able. Bench Science FTW!
“We’d like to create a magazine for the scientist in all of us.
It will have simple How-To’s, like extracting the DNA of a strawberry using kitchen materials. But on the next page could have a paper on the validity of using Bacillus Subtillus as a model organism. We’d feature extraordinary citizen scientists who are doing extraordinary things in abnormal labs (aka garages, closets, etc). We’d also give legal and safety tips to inform and protect citizen scientists from some of the dangers they could run into.”
