Thanks to the inestimable efforts of [Valentin Huen](http://colorsaregood.com/index.php), we pulled together a whopping [500 IR Throwies](/projects/ir-led/throwies/) for the Media Lab's latest 99 Friday dance-party _cum_ project-showcase. I use "we" rather loosely: I was racing against a conference paper deadline, so Valentin heroically recruited a small army of people to scale up the [IR Throwies](/projects/ir-led-throwies/) project. It came off pretty well.

My circuit board order came in -- it's always astonishing how tiny the things are, these boards are about the size of two postage stamps, side-by-side. The "barebones" option from Advanced Circuits is a pretty good deal too. These cost $8.90 apiece, which is pretty reasonable. I know that [APC Circuits](http://apccircuits.com) has really quick turn-around for boards with solder mask and such, but I didn't need it. I'm mostly proud for remembering not to pour a groundplane, as it makes it a pain to solder.

In preparation for a workshop last weekend--I populated the ten bare-bones boards I'd picked up from Advanced Circuits (see my last [post](/posts/2012/8/31/building-boards/)). I've done a bit of this now, but with [Brian's](http://bdm.cc) ever-essential help, I got really cruising. The ten boards probably took about an hour with a few hiccups.

I've been vaguely attending a printmaking class at Harvard. I can't say I've commited myself, but I have learned the rudimentary basics of etching. Now, with a standard etching, you use a scraper or scribe or pointy nail, or whatever, really, to scratch away at a coating applied to smooth sheet of copper (or zinc, in this case). Those scratches expose the bare metal, which you "etch" (ah _hah!_) in an acid bath. You fill the resulting grooves with ink, wipe off the rest, mash some paper down, and there you go. That's all well and good. After all, it's how Dürer, Rembrandt, Picasso, and some other famous dudes made it happen. But since we've got a lot of toys to play with at the Media Lab, it seems a shame not to use them.

### Open Source Hardware Summit
Recuperating this week from a grand time in New York City. We converged on its gray shores last week to stop by the [Open Source Hardware Summit](http://summit.oshwa.org/), where people vaguely gesticulated in the direction of "open source" and show-cased their projects. The good men (and they are that) of [Industry City Distillery](http://drinkicd.com) were there, handing out thimbles of vodka.

I've been working on the software for TapClip--which is rolling along, in preparation for a workshop next week. So far, it's working pretty well, though the `minim` library is causing me some grief. There appears to be a noticeable lag-time when using `loadSample` to queue a `.wav` file in memory.

I've been returning to aquariums with a force, lately, rigging-up a new set-up with a couple of neon tetras and a dozen-odd cherry chrimp that I picked up from Ebay.{{ macros.render_footnote("shrimps-1", "1")}} I got started with aquariums years ago, in elementary school--I don't recall why, exactly--but perhaps it had something to do with growing up by [Allan's Aquarium][allan], one of the finest fish stores around.
-At any rate, with aquariums on the mind, I dredged up my very first forays into the _Internet_. These are gems from the `rec.aquaria` usenet, now archived on Google Groups. I remember posting these, sitting on my dad's lap on the dial-up that we had from UCLA.

-Last week I finally got round to running some experiments with the laser cutter and hard-ground that I've been meaning to get to.

-
-
-I used some simple Processing code to generate the shapes (at least, the circles and the spiral), and burned the resulting designs into zinc plates, before etching them normally. I was skeptical, initially, because it appeared that the laser had not burned down to the bare metal--and even a thin layer of ground would prevent the acid from doing its work. That didn't appear to be a problem, though, once I dipped them in the nitric acid. Even so, I wasn't convinced until I actually pulled a print. They came off surprisingly nicely.
-
-I daubed out a few of the artifacts that were left in the ground from its various journeys from Harvard to MIT and back, but left most of the them (you can see the aphaltum in the nitric acid bath).

-
-Though I was concerned that the laser-burned line had not reached the zinc layer, you can see from the bubbles developing on the metal surface.

It stings a little.")}}

-### Moving on
-Working with the laser cutter was surprisingly unpredictable. The uneven nature of the hard ground meant that the laser melted through it somewhat irregularly, skipping areas with relatively more ground. The combination of hand-work and machine-guided precision is something I'd like to play around with more. Something definitely be worth experimenting with is the use of other ground materials that might give different results in the laser cutter.

I headed over to Utrecht Art Supply earlier today to act on a hunch that I've had for awhile. They've got a nice selection of writing and drawing tools, and I picked up a variety of very, very soft graphite pencils. I didn't even know they went up to [9B](http://en.wikipedia.org/wiki/Pencil_hardness#Grading_and_classification), but there it was--a gleaming rod of solid graphite. It had a nice heft to it, too. I got a range of hardnesses and headed back to the lab.
