Projects Update 9/9/2012

Sunday, September 9th, 2012


It's been a while since my last post and things are starting to slow down a bit so I thought I'd make a quick post. First off, the automatics saw stop/pusher project that I've been working with a few other people at the space on is making a little progress. Above you'll see the initial prototype pusher hardware which we just got up and moving. It's a chain driven system with a 405 oz/in NEMA23 stepper driving the pusher. The electronics and software are coming along nicely as well and will hopefully be integrated and working soon.

Why make an automated saw stop/pusher? Well tons of the stuff made at the space is basically a whole bunch of precisely cut 2x4s, like our big room tables:


There's 4 of these in the big room and a few more of similar construction in the shop area and we need to make more. Having a cut list and a device that automatically sets a stop and adjusts for the kerf of the saw when making successive cuts makes building these things super easy. It can also be used with other tools around the shop to help you do stuff like drill holes in a part at regular intervals. Hopefully it'll be a useful add-on to the newly constructed cut off bench in the shop.

Nanuk 920 case

Next, a client of mine pointed me to these Nanuk cases for a potential cost down on a project. If you've worked with Pelican cases before these should look pretty familiar. They seem a little less sturdy than a similar sized Pelican, but not by much, and have the same nice feature set. One thing you may not know about Pelican cases is that Pelican sells an add on frame for most models that screws in to the case and allows a panel to be mounted to the inside to make an awesome project enclosure. These Nanuk cases can be found significantly cheaper and have lip and a set of holes on the inside of the rubber seal of the case that eliminate the need for a separate frame:

I'm definitely going to be using these for future projects!

Lastly, I'm going to be slowly rolling out new enclosures for the BeagleBoard, APC, and Raspberry Pi single board computers. If you've got any suggestions for other systems or projects that need enclosures or want variants on designs I already have, let me know!


Rubber Band Gun Business Cards!

Monday, April 23rd, 2012

So I made a new business card for my design and fab work that turns into a rubber band gun! I've posted the design up on Thingiverse if you want to look at the source files and some additional pics. One of my friends threw it up on reddit and it kinda took off from there (I was #2 on the front page this morning)! For those interested, you can get some cards with your own info on them from my store.

BeagleBone Enclosure

I've made a couple of minor changes to the BeagleBone enclosure kit.  First off, they're now available in clear for those who want to admire at their little embedded computer but also keep it in a nice, safe plastic shell.

Next, I've modified the SD card slot to make it easier to insert and remove the SD card and accommodate the changes to the SD slot changes made in the A4 revision.

Finally, I switched to smaller diameter standoffs to avoid potentially hitting R150 on the bottom of the boards.

If you happened to be an early adopter, send me an email ( and I'll get you some new standoffs and a new SD card panel!

In other news I've created a new page where you can find all the instructions for the various kits I offer that will hopefully be updating more frequently in the coming weeks.


CCCKC CNC Back in Action

CNC Mill

After the move to the new location the big CNC router started acting up.  The problem was eventually tracked down to the Y axis lead screw acquiring a slight bend in the move.  Thanks to the efforts of Dave Dalton and Luis Rodriguez (thanks guys!), the lead screw has been replaced and the router is up and churning out parts again.  Luis and Nick Woods have been cutting stools for the big room:

The Mehls cut the parts for a Link cosplay sword:

And I cut out the mounts for the R3's hold down rails and the blank for its sacrificial top:

Hopefully we'll be seeing more member projects rolling off the router soon!


R3 Update 1/27/2012

R3 CNC Machine

I've been a bit busy lately and mainly working on other people's projects, so I haven't had a lot to post lately, but I have been working on the R3 (RepRap Router) again.  My laser-strap prototype has taken up residence in the new CNC room at Hamerspace and is now sporting new endstops and tool mounts including a boom for its powerful little flex shaft spindle.  I got in a quick test of the tool mount and spindle last meeting and grabbed some video:


Here's some additional pics:

Next on my list of stuff I need to do for this prototype is to get the hold down system in place and mill the sacrificial top flat.  I plan on embedding some extruded aluminum T-slot that works with 1/4" hex bots into the MDF work surface like the bigger CNC setup at the space and using standard woodworking hold down clamps for now and maybe design some milled or 3D printed ones as the project progresses.
