<span class="s1"><span style="font-family: Courier New, Courier, monospace;">A few weeks back a fellow from <a href="http://arrayfire.com/" target="_blank">Array Fire</a> contacted me about having a couple of enclosures made for his company’s upcoming attendance at the <a href="http://www.gputechconf.com/" target="_blank">GTC</a> (GPU Technology Conference). Notice the lovely logo that’s been etched on the top of the enclosure, a nice touch. This is version 2.0, since Array Fire didn’t need access to the SATA (through the top) or the GPIOs. After a protracted USPS 2-day priority delivery ordeal (closer to 6 days) the enclosures arrived, here are some pics <a class="g-profile" href="https://plus.google.com/103806307854546961939" target="_blank">+Shehzan</a> shot. </span></span></div>

<span style="font-family: Courier New, Courier, monospace;">Alright, perhaps the above quote is a touch extreme, but only a touch. After failing to achieve an acceptable degree of accuracy for my block lifting mechanism with laser cut parts I've started down the path of 3d printed parts. Many thanks to <a class="g-profile" href="https://plus.google.com/106182499924088110097" target="_blank">+Duane Johnson</a> for the use of his delta printer and for putting up with my endless revisions.

<span style="font-family: Courier New, Courier, monospace;">This is the carriage piece that will attach an articulated block to the rest of the lifting mechanism. Unfortunately, my design had insufficient and/or no tolerance so none of the hardware apertures we're large enough. Thus ensued a bunch of sanding, grinding and filing until the hardware DID fit. So, back to the drawing board. Before I wasted a bunch of PLA on another failure I decided to design a calibration sheet (stepping bore holes up by 0.5 mm for a few iterations). Designed and printed, it told me what I needed to know about tolerance. Next came this:</span></div>

<span style="font-family: Courier New, Courier, monospace;">The lift head, a piece that keeps the power screw and alignment shaft in place and stops the carriage from lifting to far. Made a mistake assuming that a 1 mm wall of PLA was sufficient to hold the nut for a set screw in place, the part broke as soon as I tightened the set screw. Back to the drawing board. Undeterred I redesigned the lift carriage and came up with this:</span></div>

That is, until last night and the answer was YES, just be careful of the fumes. I've been wanting to make a better looking tsuba (guard) for my bokken (wooden practice sword, in this case for Iaido). Here are the results of my first test, I think there's an interesting future in making custom tsuba.</span><br />

<span style="font-family: Courier New, Courier, monospace;">In other news I cut and planed a variety of different types of wood (fir, cedar, myrtle and purple heart) to glue up on the bokken form (see previous post). The softer woods I'll be using first for practice so as not to screw up my limited stock of exotic wood. I'm starting from <a href="http://www.instructables.com/id/How-to-Make-a-Japanese-Bokken/?ALLSTEPS" target="_blank">this</a> instructable I found a while back, modifying it by using 3 strips of wood instead of 2 and a 5/8" round over routing bit (for the blade edge). Here is some fir on the form:</span></div>

<span style="font-family: Courier New, Courier, monospace;">Thankfully, most of this piece is going to end up frosted (in this case roughed up with fine grit sand paper) since the bubbles in the glue job look annoyingly ugly.

Much to my dismay I set the tolerances too tightly and the parts required a lot of filing and boring before I could install the hardware (which led to a misaligned linear bearing).</span></div>

I decided to dig some images out of our collective past and turn them into wood engravings. We're both Dungeons & Dragons fans so I selected some of my favorite illustrations from the Fiend Folio and throw them into a composition. Here's the result (note, this was a test run on a smaller pieces of wood): </span><br />

(snort, like anyone other than bots and scrapers read this thing). I've been meaning to add some posts but I've been so damn busy I haven't had the time to put together anything coherent. So, here's an attempt at coherence and a summary of my recent tinkering and design activity.</span><br />
<span style="font-family: Courier New, Courier, monospace;"><br /></span>
<span style="font-family: Courier New, Courier, monospace;">A month or two ago I joined a maker space named <a href="http://www.enjigo.com/" target="_blank">EnjiGo</a>. It's a relatively new organization (a merger between MakeSLC and a robot building club), and there are quite a few things that need to be done for the organization. When I joined there was no logo, no brand and no real identity, which equates to a very slow word-of-mouth growth strategy (though with member attrition it seems like we're lucky to keep a constant number of members). For those not familiar with maker spaces, these are collective spaces with room to work, shop and rapid prototyping tools and a group of members who have expertise in a variety of different fields (often some brand of engineering). In EnjiGo's case there's also a mandate to educate the community and share skill sets. As a paying member I'm allowed to vote on the behavior of the organization and since groups such as this can tend towards apathy we have termed ourselves a Do-ocracy (entitlement through action). Anyway (back on track to some self aggrandizement), I took it upon myself to design a logo and build a window sign to replace the makeshift, barely legible masking tape on window spelling E N J I G O.

<span style="font-family: Courier New, Courier, monospace;"> I used the my laser cutter to make the sign from some spare luan plywood I had floating around, learned a painful lesson regarding how tough that shit is (way tougher than birch of a similar thickness and higher quality). Here's a sequence of images show construction and final result:</span><br />

<span style="font-family: Courier New, Courier, monospace;">Now, an important thing to note is that EnjiGo's space is about 5000 square feet and the rent is not insubstantial and as I previously noted the growth of the organization is happening slowly. We need more members and we need to communicate what a great organization we are (trying to be), to this end I've started designing printed marketing material. Here's a poster that should be arriving soon from the printer:</span></div>

I think the pictures speak for themselves, the higher power settings blow right through wood, the balsa also has a tendency to catch fire which is exacerbated by the high flow rate exhaust fan. I finally got the settings figured out for a variety of thicknesses (cutting with little or no burning).</span><br />

<span style="font-family: Courier New, Courier, monospace;">I'm now in possession of a laser cutter... YAY!!! Now comes the annoying part, laser cutters need more than just a power cable, they need air compressors, exhaust fans (attached to exhaust ports) and water pumps for laser tube cooling. To put it another way a laser cutter needs a home, a home where you can cut holes in the wall and blow all the noxious smoke and cutting particulates out. Currently this home doesn't exist (and the laser cutter is still in its shipping box), BUT worry not sports fans I'm working away at making a new shed into which I can put all the stuff in our current shed. Here's a pic of the new shed's framing (this toddler was wandering around the backyard, no idea who she is):</span><br />

<span style="font-family: Courier New, Courier, monospace;">So, I've been dreaming up uses for the laser cutter I'll soon have unlimited access to. I remember as a kid spending hours playing with a simple balsa wood glider. Here's a balsa wood flyer for adults... it would be an electric RC plane in the "park flyer" class. The fuselage, wings and tail would be reinforced with </span><span style="font-family: 'Courier New', Courier, monospace;">carbon fiber paneling, sandwiched</span><span style="font-family: 'Courier New', Courier, monospace;"> between laser cut balsa wood.</span><br />

Im using a SM-S3317S full rotation servo to drive the set up. I have yet to puzzle out how it "works" with the Arduino servo library, that is to say I can figure out how to get it going, but not how to stop the damn thing. I'm sure a little more research will reveal the answer. At the end of the day that's not the servo solution I'll be using, so doesn't matter too much. As <a class="g-profile" href="http://plus.google.com/117722776512974349186" target="_blank">+Jason Hoff</a> pointed out I need to use a power screw with a more course thread to increase the blocks speed, thankfully I already have some different screws for this use. Anyway here's the video:</span><br />

<span style="font-family: Courier New, Courier, monospace;">First let me say that upon assembling block lifter v0.2 I have found numerous flaws in design (I'm sure I've said this before). My solution for most of these flaws was drill bigger holes and use more glue, this strategy seems to have lead to misalignment and imprecision. Regardless I think this prototype will basically do what it needs to. Going to redesign the carriage component so it's easier to assemble and align.</span><br />

In addition to prototyping designs I've also been experimenting with a variety of adhesives, all of block lifter v0.1 was glued up with one version of epoxy or another. As I'm putting together v0.2 I've used epoxy for some of the heavy wear and tear parts, I'm also seeing how Gorilla Glue works (since I've never used the stuff). Biggest surprise with Monkey Paste is how much it expands as it sets and cures. Sure stuff I've read a variety of accounts (including the instructions) saying that it expands (3-4 times), but actually seeing the stuff bubble it's way out of joints is weird. Here are some pix:</span><br />

<span style="font-family: Courier New, Courier, monospace;">The above pictured carriage brace is probably the most jacked up part of the prototype, it's going to need to be completely redesigned. The tolerances were too tight and the sockets for power screw's nut was too small by a few millimeters. This is, of course, what prototypes are for, screwing things up and fixing them with jury rigging parts and lots of glue.</span></div>

<span style="font-family: Courier New, Courier, monospace;">A quick rant tonight. Got the cutting done for block lifter V0.2, I only made a couple of mistakes, nothing a little grinding with the Dremel won't fix. In V0.2 I decided to use 1/8" (3mm) wooden dowels for alignment this time around, they should impart better alignment than the metal rods I was using (I've had better success with wood dowels in other projects). So, I'm running around doing errands and I decide to duck into Ace and pick up an 1/8" dowel or two. Because "Ace is the Place", right? The ads that I've seen on TV tell me that Ace is a no hassel place to pick up things you need for any project you're doing. They have friendly helpful staff who will help me find what I need, that's what the ad says... Well, wrong on both counts, no help, no dowels to be found. Now I have to wait till I can make it over to Home Despot before I can start gluing things up. To hell with you Ace!!!</span><br />

I'd still like to see how well or poorly this design works. As noted, my drill holes are not super precise (and the alignment of a number of key parts was a bit skewed while they were being epoxied together), so my trusty hand reamer got some good use today. Here are some shots of the assembled rack carriage as well as shot of the carriage held in the block (held together with a rubber band).</span><br />
