Flying Lotus
We went to this show last night. It was interesting; roughly something like abstract hip-hop music with some neato visuals.
theater spray foam
The theater was stripped down, we ran some wires for speakers, and then just had the spray foam people here. Now we can have it all put back together.

A couple pictures from robot/programming/LEGO camp this summer:

Also,
since I am largely pathetic and no one person could do justice to Burning Man, here is a link to some pretty nice pictures from someone I do not know; referral from Boing Boing. Some of them are pretty awesome pictures and I’m sure the Web has plenty more to offer. Here’s one option: the burningman2014 tag on flickr.
burning man outfits
I managed to throw together a shirt and pants:
Thuy made a couple things too but no pictures. We spent much of the weekend working on lighting for the outfits. I didn’t take any picture/video of mine but here is a picture of the pieces of Thuy’s, which shows the controller, touch-sensitive pad, accelerometer, color sensor, and one ring of LEDs on the left, which will go on the front, and a pattern of LEDs (aka the Snail) that will be the back:
Here’s what the room looked like:
OLED lighting conditions
I moved my little OLED screen to the clock location and sent my clock module to Arron fo be 3D scanned, so we can model and print a replacement.
The weather was nice today so I had the top off and took a few pictures under various lighting conditions to show how it looks compared to the A/C-control display. Under all lighting conditions it’s at least as bright. I’m thinking for my final display, I will use two of these OLED screens or two slightly larger screens (1.7″ instead of 1.3″), maybe in combination with an LED-segment display. Still considering options.
These shots were all taken within about 5 minutes of each other. Around 6:30 pm, first with light coming in the windshield, behind the display, then in the shade but with light from behind, and then with light directly on the console at a low, partially sideways angle:

Not sure who this is but it’s one of them:
Prototype in-car display
This is a display I’m working on to replace the clock in the NSX. It will show various parameters from the data-logging system I have, the Zeitronix ZT-2. In this video, the display is configured as follows:
From the bottom to the top,
- At top is a bar graph showing boost, following the same color coding as for the numeric MAP display below.
- Numeric displays show Manifold Air Pressure (MAP) and Air:Fuel Ratio (AFR).
- MAP is red under vacuum conditions (no boost), yellow when entering boost, and then green above 4 psi (max is about 6 psi with this supercharger setup).
- AFR is red when not under boost, white when AFR is below a desired value based on boost, and blue if above that value. I used a simple set of conditions where under a certain boost (currently set at 4 psi), the AFR must be under a certain value (set at 13 currently). For MAP above that boost threshold, the AFR must drop linearly (currently set with a slope of -0.5, so AFR must be under 12 at full boost of 6 psi).
- The fat bar near the bottom is the tachometer, which changes color to indicate shift point (green > red > blue).
- On bottom is a bar graph showing throttle position.
All the color-changing, moving elements are pretty confusing, and the display is very small. I need to think about the best information to display and the best way to display it. But this is a test setup to try out a few things. Figuring out the best way to draw bar graphs, changing colors, and even the numeric values took some time. There are still a couple of weird issues with reading the data consistently, as you can see in a flash of the display where MAP has a problem (at 0:12 in the video).
I don’t think there is any need for MAP unless under boost, so the numeric display for that can go away. TPS is similar: it’s not really something I want displayed. I will probably change the tachometer to only show up from 7,000-8,000 rpm, as a shift light. Otherwise, I have no need. So that leaves AFR and the boost gauge. I may do AFR with a bar graph too, as reading numbers isn’t all that useful. I do have a separate, very bright 4-digit alphanumeric display that I am considering adding, which could display AFR only when under boost, for example. I also have to think about how to mount the OLED in a way so that it’s shadowed from the sun, as that will be required for readability. Fun project though.
Infrastructure
Evaporative cooler a.k.a. swamp cooler:
Bucket cascade for treating gray water; the top is for flocculation and settlement, then a valve will allow flow to the bottom two, which will be sand filters and chemical sanitation:
Yurt
It’s getting there. We will fold the bottom part to a flat package and the top part to a mostly flat package. The two will be assembled on the playa.
