Gareth has generously offered an autographed copy of The Best of MAKE, so there is your motivation. Take a look at what other MAKE city chapters (Make:SF, Make:NYC, etc.) have done and come up with something fun for DC. Judging will be conducted by a select committee of experts in the field (those of us organizing Make:DC). Email submissions to me. You can send me multiple submissions. Deadline is Monday, the 14th, unless I change it. This is just for fun, so please don't be intense about it. Anyways, have at it!

The cubes are pretty fragile so it is worth thinking about how to get them home - they won't survive in a backpack unprotected. You might get by with a 25W pencil soldering iron from Radio Shack: http://www.radioshack.com/product/index.jsp?productId=2062737 but if you get serious you will want something with temperature control. Avoid the "cold heat" irons and the high-powered guns with trigger grips that aren't meant for electronics. I will bring some extra solder that people can use. --Tim --- Jacob Smith wrote: > Hi! > I don't know if this has been addressed already, but I had a > couple of > questions about the event on Wednesday. > > Does the "ne plus ultra" kit include the box that all of the > stuff goes > in?

Slightly OT: ceramic floor/wall tiles make good heat resistant surfaces for soldering. They can be had for less than $1 from a home store. A little unwieldy to haul around in a backpack, perhaps, but good for turning your desk into a soldering station.

It is easy to change the patterns, so maybe people can make some cool animations instead of working on Wednesday and then bring the modified files to the workshop to try out. It is also easy to change the Arduino pin# to LED assignments, so wiring differences can be corrected in software through trial and error. My plan is to build the LED cubes on protoboard squares and then attach header pins to the bottom so that the board can be plugged in right on top of the Arduino (like the shield boards). This minimizes the amount of additional wiring needed to hook up the cube. The LEDs I will provide are pretty bright even at 1/10th of their rated current. This allows the plane drive transistors to be omitted, so the Arduino digital outputs will drive the LED planes directly. This was the original Make: miniPOV design, and it makes the circuitry and wiring simpler. I will bring some transistors in case anyone wants to make the drive circuit and crank up the brightness. I am writing up step-by-step instructions for building the cube and attaching it to the board. I'm not sure I'll have time to add in pictures of each step, but I'll bring a webcam so people can see some visuals in case my prose is insufficiently clear (pretty likely!) --Tim -------------- next part -------------- A non-text attachment was scrubbed...

The first joint DorkbotDC + Make:DC work meeting attracted 63 participants (twice what we expected!) and, although 2 hours was barely enough to get folks started on their LED Cube, it was great to see so much enthusiasm. Thanks to the Marian Koshland Science Museum for their hospitality and congeniality. I want to encourage you to use this list to ask questions and to provide others with resources and hints so that you can finish the project at home. We'll be working on a step-by-step instructable to put on the DorkbotDC and Make:DC websites and we'll let you know when it's up. A big shout-out goes to Tim Slagle for the time he spent getting the best LEDs at the best price, prepping/packaging the kit parts, writing up instructions and building that lovely cube prototype and the flashy software he provided (His test app was sent to the list on 1/16/08 as an attachment called LEDcube.pde. If anyone needs it, drop a line here. We'll also put it on the website with the instructable.). Kudos also to Mark Adams for his contributions to the kit and logistics including hosting the prebuild, and for building v1 of the cube and software prototypes. They both went through *a lot* of effort on our behalf! Of course, we also need to thank the Maker Store for giving us a deep discount of the Arduinos.

I inadvertently grounded mine to 17, 18, and 19, and used 15 and 16 for the eight and ninth pins, which (happily) required only a software change. Kudos to Tim for that! This project was wicked fun, and I can hardly wait for our next Dorkbot. In the meantime, if anyone can use virtual assistance via email, or physical assistance from somewhere close to Capitol Hill, I'm happy to do what I can (keeping in mind my skills are dubious, but my enthusiasm is unquestioned). Once again, thanks to everyone who worked (and played) hard to make this happen. The Arduino seems like it's going to be a lot of fun to have lying around. Best, David.

I was doubting my connections for a while, but figured out I had two dead LEDs. The ones I had lying around the house weren't the super-bright orange ones I got in the kit, but they did okay in a pinch. If you're interested in seeing my final version, I just posted a video on my site: http://www.stationinthemetro.com/index.php/archives/2008/01/18/makedc-led-cube-workshop/ Thanks again everyone for helping put this together!

Here are the cube-building instructions that I handed out at the workshop. Sorry for not sending this out sooner, I had some catching up to do in my real (non-LED-related) job after the workshop was over. And I needed some sleep :-) I was working on this document right up until I had to leave and unfortunately didn't finish the sections on attaching the connections to the common plane cathodes or wiring up the Arduino pins to the cube. I hope to complete them, and to add info on making a LED plane assembly fixture, but it's not clear when I'll have the time and I don't want you all to wait any longer. So, please forgive the incomplete and un-proofread nature of the document! My goal would be to put together a nice Instructable with the completed instructions and some nice photos of the steps. I'll certainly announce on this list when it is available, and I'll send out any expanded versions of this document as well. --Tim -------------- next part -------------- A non-text attachment was scrubbed...

I finished my green cube up today, figuring out how the planes were wired by reading back through the demo code that was posted here earlier. I managed a program that (passably) spells out my girlfriend's name: T - A - L - I - A, from top to bottom. Now only if she'd sit down and get her red cube done ;) That's a nice bit of code you've posted, David. I went ahead and added something to it, a drop-in replacement for randomLight(). It checks to see if the random() call for the anodes returned a number that corresponds with a pin that's PWM-capable and will randomly choose to fade it up and back down if so. The fading randomLight() func is attached. Thanks to MAKE and Dr0kbot for that shindig the other night. This was my first real electronics kit aside from playing around with one of those Radio Shack 150-in-1 kits when I was 10. /dale -------------- next part -------------- void randomLight() { int pwm; int perhaps = random(2); int i = random(3); int j = random(9); // See if we've stumbled on a PWM-capable anode // These pins are PWM-capable on the Diecimila if (perhaps == 1 && (anode[j] == 3 || anode[j] == 5 || anode[j] == 6 || anode[j] == 9 || anode[j] == 10 || anode[j] == 11)) { digitalWrite(cathode[i], LOW); digitalWrite(anode[j], HIGH); for (pwm = 0; pwm <= 255; pwm += 5) { analogWrite(anode[j], pwm); delay(6); } for (pwm = 255; pwm >= 0; pwm -= 5) { analogWrite(anode[j], pwm); delay(6); } digitalWrite(cathode[i], HIGH); digitalWrite(anode[j], LOW); // We havnt got a PWM-capable pin so do a normal bink on/off } else { digitalWrite(cathode[i], LOW); digitalWrite(anode[j], HIGH); delay(delayTime); digitalWrite(cathode[i], HIGH); digitalWrite(anode[j], LOW); } } From daleg at elemental.org Mon Jan 21 19:29:12 2008 From: daleg at elemental.org (Dale Ghent) Date: Mon Jan 21 19:29:20 2008 Subject: [dorkbotdc-blabber] Arduino code for LED cube In-Reply-To: <194A88EE-679E-4AE5-9C2B-9B79DD96A013@elemental.org> References: <890143.48718.qm@web30607.mail.mud.yahoo.com> <586d73570801191929p3a79d36aj78085e94741e5830@mail.gmail.com> <06F005E1-481C-425B-A64F-0A2036ECC6EC@steamermedia.com> <586d73570801201940k2367473dr3753e7d9d3587580@mail.gmail.com> <194A88EE-679E-4AE5-9C2B-9B79DD96A013@elemental.org> Message-ID: On Jan 21, 2008, at 1:03 AM, Dale Ghent wrote: > That's a nice bit of code you've posted, David.

The fading randomLight() > func is attached. Okay, I spent some more time this evening using David's great program as a base and added more stuff. In the the PDE file attached to this email, the different sequences are randomized with the random single lights sequence having more weight (hey, I like that one).

They settle into predictable patterns pretty quickly- not a huge surprise. Once again, I'm sure there are plenty of bugs lurking in here, but if you want to see your LED cubes blinky blinky to the tune of one of the largest egos of our century, this Wolfram automaton is for you. Remember I mis-wired a few pins, so you might need to change my numbers 15-19 to 14-18 and re-arrange as well. Being a Dork is great fun. Dale, I've got sensors of various kinds lying around- maybe tomorrow I'll try your idea and hook one of them up to the extra analog pin. Night, all. -db.

I have been working on "3D VU Meter" as well- my approach is not nearly as comprehensive as yours- I was attaching "chopped" values from the A/D converter to specific frames of animation. I still don't have it working perfectly, but you do get some flicker roughly approximating the input music... :-) As soon as I get access to the machine with the code on it, I will upload it to the list. -Mark Dale Ghent wrote: > On Jan 21, 2008, at 1:03 AM, Dale Ghent wrote: > >> That's a nice bit of code you've posted, David.

I think the toothbrush holder would fit a boarduino making a nice waterproof hand held device. You can put LED's on the inside and view them through the translucent plastic.

I spoke with Tim Slagle on a back channel and he was super helpful with the pros and cons of going the LED route. Ultimately, I decided to not undertake the project as digiatl camera sensors don't get fooled by LEDS like our eyes do. White LEDS are actually blue LEDS with a phosphorus filter and the sensor picks up more blue than our eyes do. I think the multicolored LEDs have the same thing going on. It's really difficult to get a shot that's balanced from frame to frame unless the shutter speed is a multiple of the frequency of the pulse from the PWM. (Which is why I try and shoot indoor fluorescent lights at 1/60th or 1/30 of a second so I can exactly capture one or two wavelenghs). However, this color shift shouldn't affect your lighting and stage work. It may cause a little havoc on the photographer taking photos for the promotional material, but nothing major.
