Coming Up in June

Did I not do this for May? How come nobody told me I didn’t do this for May? Hrm. Sorry about that! Well, to make up for it, I’ve got a whopper of a June loaded with goodies for you. Will that make up for my slacker-hacker goodness? Let’s hope so cuz it’s all I got.

Our new SeeMeCNC Rostock Max 3D printer construction in progress

Our new SeeMeCNC Rostock Max 3D printer construction in progress.

June special events / classes:

Friday, 5/31 – Sunday, 6/2: Denver Comic Con! – If you are attending Con, make sure you stop by our fan table just outside the main entrance to the Con. We’ll have one of the 3D printers there and all sorts of fun stuff to look at and people to talk to about what we do.

Saturday, 6/1 – Sunday, 6/2: Open House and BBQ – If you aren’t going to Con, or even if you are but want a break from standing in line, come on up to the space and hang out both Saturday and Sunday this weekend. We’ll have the grill fired up cooking meaty snacks and will have people around to answer questions and give tours.

Tuesday, 6/4: Radio Heads, 8 p.m, in the classroom – A group created to explore different aspects of software defined radio. Topics to be addressed include both the reception and transmission of RF signals, the processing of data captured from the ether, cell phone networks, and ham radio. This is a group, not a class. There is no instructor. Just a handful of similarly minded people trying to learn something at roughly the same time. If you have a pet project you think might apply to this group feel free to propose it.  RSVP on Meet Up.

Saturday, 6/8: Intro to Designing with Microcontroller ICs in the Raw w/Th3 D0n, 1 p.m. – 4 p.m, in the classroom – While many folks are getting exposed to embedded applications using Arduino and other embedded platforms, sometimes you want to start a design by selecting and using raw microcontroller chips in order to save cost, reduce device footprints, or just to learn about the microcontrollers at the lowest level. Some topics of the class will be:

– What is a microcontroller?
– Selecting a microcontroller IC
– Hooking it up to the real world (electrical and logical considerations)
– Programming microcontrollers in C

As a real example of a microcontroller project, we will refer to the schematics, circuit, and software developed for the 303/Denhac badge created for last year’s Defcon.

This will mostly be a presentation, with demonstrations using the303/Denhac Defcon badge. As such no materials are mandatory.

However bringing a laptop etc. to access the schematics, GitHub code repository, and other resources Don will show during class can be helpful. RSVP on Meet Up.

Tuesday, 6/11: Locksport, 8 p.m, in the main room – Our monthly gathering of lock enthusiasts led by the infamous Legion. Never picked a lock and afraid to try? If I can do it, you can too! RSVP on Meet Up.

Saturday, 6/15: Learn to Brew with Karpinski, 1 p.m. – 4 p.m, in the classroom -This class will be for beginners and those curious about brewing beer at home. We will be brewing a simple extract based pale ale in class while sampling some tasty homebrew, of course!

* Must be 21 to attend.  RSVP on Meet Up.

Saturday, 6/15: LPFM General Meeting, 4 p.m. – 6 p.m. - In October of 2013, the FCC will open up a filing window for the first time in more than a decade to allow nonprofit organizations to apply for low-power FM licenses. Denhac intends to apply for one and we’ve already created teams to build content, manage the engineering, and handle all the administrative requirements/business aspects of running a station. This is our first of several regularly scheduled monthly meetings for everyone to get together and update each other about progress made. This meeting is open to the public and other organizations. If you want to be a part of this exciting opportunity as an individual or respresent a group who would like to collaborate with us on content, please come to this meeting and let us know who you are. No experience in radio is necessary and Denhac membership is not required. RSVP on Meet Up.

Tuesday, 6/18: Radio Heads, 8 p.m, in the classroom – A group created to explore different aspects of software defined radio. Topics to be addressed include both the reception and transmission of RF signals, the processing of data captured from the ether, cell phone networks, and ham radio. This is a group, not a class. There is no instructor. Just a handful of similarly minded people trying to learn something at roughly the same time. If you have a pet project you think might apply to this group feel free to propose it. RSVP on Meet Up.

Friday, 6/21: dc303, 7 p.m, in the classroom – The local defcon group for Denver. I dunno exactly what they do. They’re very serious. They kinda scare me. Naw, they’re good guys. Uh…I think. Mostly. Tilver’s nice in any event. So if you’re interested in Capture The Flag (CTF) type stuff, stop by. I’m fairly certain no one there has eaten a human liver with some fava beans and a nice Chianti. Uh…fairly certain. Please note: I may have the date wrong on this as Tilver mentioned that qualifying for Defcon 21 is June 14-16. Stay tuned.

Thursday, 6/20: David W/SFS and Denhac Present: So you want to be a puppeteer? – aka Puppet configuration management, 6 p.m. – 10 p.m, in the classroom – David Willson is back by popular demand to teach us all about Puppet configuration management. David is a systems engineer, IT teacher, and freedom zealot. The SFS is a school he’s building with his friends. SFS probably stands for Software Freedom School.  RSVP on Meet Up.

Saturday, 6/29: Everything You Need to Know About Bitcoin, 2 p.m. – 5 p.m, in the classroom – What is Bitcoin and how does it work? Why should you care? What is it good for? How can you buy, mine, sell, trade and otherwise participate? What are Litecoin, namecoin and other altcoins? Chris Hansen is here to tell you. Please bring a laptop or smartphone with you. RSVP on Meet Up.

Tuesday, 7/2: Monthly Denhac Board Meeting, 7 p.m, in the classroom – The monthly board meeting where we make business decisions and try not to talk over the top of each other. Due to several scheduling and travelling conflicts, the June board meeting will be at the beginning of July (just this once). Open to the public.

As usual, the calendar is subject to change. There are nearly always additions throughout the month and we’ll be updating the calendar and the website with more information as it becomes available so be sure to check back each week for new announcements.

Weekly events:

Every Tuesday: Open House. A night for members and non-members alike to come hang out with like-minded folk, take a tour, and find out what Denhac is all about.

Every Thursday: Work from Denhac Day. Do you work from home and need a break from your partner, your kid, your cat, and/or the deep, dark recesses of your idle mind? Come work at Denhac where there’s a water cooler and company but no cubicles or cats.

Every Saturday afternoon: Open House. Another opportunity for members and non-members to come hang out with like-minded folk, take a tour, and find out what Denhac is all about. Plus, every Saturday through the warm months, we’ll be throwing open the bay door and firing up the grill through the afternoon.

Shiny New Thing!

A few weeks back, we were contacted by a crew from SeeMeCNC – a 3D printer and laser cutter company based out of Indiana – letting us know they would be passing through Denver on their way to the Bay Area Maker Faire and asked if they could stop by and hang out with us for a few hours and show us their products.

Of course we said yes because Yay! Look! Shiny stuff! And then we invited all our friends.

Gang's All Here

We’ve got friends!

So Sunday this past, the guys pulled in late afternoon as promised and let us get our paws on equipment we’d never seen before.

Shiny!

Shiny!

And it was SO COOL! We ended up procuring one of their Rostock Max 3D printers for the space.

I KNOW! RIGHT?!

RF Modeling a 3D Printed...um...thing

RF Modeling a 3D Printed…um…thing

The bad news is they sell them in kits so it’s not quite ready for use. However, we’ve assembled a team of members together to work Sundays on this thing until it’s built. Hopefully it’ll be ready to take to Denver Comic Con in a couple of weeks. Regardless, it’ll be ready soon and then even more crazy 3D printing fun shall commence!

If you haven’t come by to check us out yet, perhaps this will be the push you needed to head in our direction.

Here’s a video Scott took of the machine in action.

This Week at Denhac (May 13 – 19)

THIS JUST IN!!!

The SeeMeCNC guys came by the space just this evening and we were so impressed by their product – the Rostock MAX – we acquired one! It’s a kit that we’ll need to assemble and so we’re just now working out the logistics for getting it put together but very soon Denhac will have a printer capable of printing 3D objects using a machine with these standard features (from the SeeMeCNC website):

  • Over 1300 in² of build volume (11″ Diameter by over 14 3/4″ height)
  • Your model is stationary throughout the entire build process, less prone to print failures
  • High quality Laser cut, Injection molded and CNC machined parts all made by us right here in the USA
  • Comes set up for 1.75mm filament
  • Uses high torque NEMA 17 stepper motors
  • Comes standard with a .5mm nozzle for easy printing, but can use our other sizes as well
  • 450w PSU delivers more than enough power for the heated bed, hot end and accessories you could add
  • RAMBo by UltiMachine electronics
  • Positioning accuracy of .02mm (20 microns) *
  • Speed in excess of 300mm/s in all motion, not just X/Y moves ***
  • Tinker-friendly electronics and hardware. Many extra places to add your own mods to both
  • Filament spool holder incorporated into the machine (for 1lb or 1kg spools only)
  • Easily upgradeable to dual-extrusion in the future. RAMBo supports dual hotends and extruders stock

Holy smokes! BOUNCE! BOUNCE! BOUNCE!

The Rostock MAX coming soon!
