Build the eye pupils
Posted: 2005-June-19 Filed under: Lighting, Projects, The Bike With 2 Brains Leave a comment »I assembled the pupils of the eyes with tubing, the pipe nipples I bought, the washer/nut assemblies that make the pupils themselves, and a couple clamps. Basically, I fit the end of the bolt that's welded to the washers that make up the pupil into the end of a short piece of polyethylene tubing. I used the pipe clamp to tighten it down and then glued it into the pipe nipple on the frame. I gave it a quick test with my LED light and it seemed that it might just work.
The final paint job
Posted: 2005-June-8 Filed under: Frame, Projects, The Bike With 2 Brains Leave a comment »I added masking tape to the portions I don't want painted and brought them to Austin-Spencer Collision (2433 Brighton-Henrietta Townline Rd.) I talked with Mark who didn't give me a rosy outlook for getting done by Friday — I hustled to finish the frame so I could bring it to the ARTWalk (University Ave. from Atlantic to Merriman) Muse-a-Thon on Saturday, June 11. However, after he had his painter check it, he felt they could finish by Friday afternoon.
I took apart the wheels I had (the front rims are being painted) and reassembled the tires for the back wheels. It took a while to get the hang of assembling the wheels right — alternating the spokes the right way and all so it all fits together. I tightened up the spokes and got them "true enough:" they're still a bit warped, but good enough for what I need.
I used some office chairs I had and took them apart to use temporarily on the vehicle.
I stopped by Austin-Spencer Collision (2433 Brighton-Henrietta Townline Rd.) around 4 on Friday and by the time I left around 4:45, they still weren't done. Mark said he'd try to get there tomorrow morning around 8 and I could come by and pick it up, but that leaves me almost no time to finish building stuff, so I suggested we just call it off. I doubt that I could be ready in an hour from the time I get back with this stuff until the time that I could get to ARTWalk (University Ave. from Atlantic to Merriman) since I had to build the bike wheels, build the seat, and getting everything taken apart and put back in the car (the event was from 10 a.m. to noon.) There's just no way. I e-mailed some people I told about it and called it off.
On Monday I picked up all the parts. They look really good with the navy blue automotive clear-coat applied. Definitely much different than the scrappy metal I started with. When I assembled the front wheels, it took nearly 2 hours to make two wheels so I never would have made it to the ARTWalk event on Saturday.
Getting started with paint
Posted: 2005-June-2 Filed under: Frame, Projects, The Bike With 2 Brains Leave a comment »I had found a metal cage in the garbage across the street so I cut it to a smaller size and welded it together. It's for the top of the rear shelf so people are tempted to use the shelf for stuff instead of riding on. I sanded it a bit and threw on a couple coats of primer real quick — it's already mostly painted.
I applied primer to the eyes and the top rails then drilled holes and tapped top rails for the brackets to hold the light tubes. I finish-welded the seat brackets, measured them (figuring I could build the seats while it's getting painted at the shop) and ground down the sharp edges.
I created a pretty decent battery holder out of the battery cage in a dead computer UPS but did a lousy job installing it. The solid metal shelf which is welded to the frame is a bad idea. It warped even more with the additional welding and I got really unhappy about it so I had to cut off the battery cage and the shelf.
I got the front end parts stripped of rust and primered. I spent the better part of a whole day painting and finished applying primer. I made hooks for all the parts so they can be painted.
Friends ride at my house

We tried it out and Peri described it as "riding a Spirograph." Courtney and Disa stopped by a little later and they rode it around as well.
Contact local musicians
Posted: 2005-May-27 Filed under: Audio, Projects, The Bike With 2 Brains Leave a comment »I wrote a letter to some local musicians asking if they'd like to contribute some recordings to play on the vehicle. The letter (in general) is as follows:
I've probably mentioned it before, but here's some more detail: I'm building an art project for Burning Man (http://burningman.com) this year that's called The Bike With 2 Brains (https://jasondoesitall.com/bikewith2brains). Basically, it's a two-person vehicle where each of two riders pedals a unicycle wheel in front of them. Steering is accomplished differentially: to go straight, both riders need to pedal at the same rate; to go right, the left rider needs to pedal faster, etc. The back wheels caster-swivel, so that's the way to control it. I'm designing a lighting system and a sound system for it as well, and I'm looking for musicians who want to submit a piece to be included as part of what the sound system plays.
I apologize for the long e-mail … most of this is the same as what I'm sending to everyone else. I want to personalize each letter, so this paragraph is especially for you, [Recipient]! (har har.)
Also, if you're available, I'll hopefully have the frame built by June 11 and have it set up as part of the ARTWalk "Muse-A-Thon" that day from 10 a.m. to noon (I think.)
Anyway, to fill in a little more background about Burning Man, the setting is Black Rock Desert, Nevada for one week at the end of August. Essentially, Black Rock Desert is one big, flat, dry, windy, ancient lake-bed. Temperatures typically range from about 40 degrees at night to around 110 in the day. One of the two closest towns is Empire which is the home of U.S. Gypsum who make drywall: the wind blows a fine alkaline dust just like drywall dust. There is no vegetation at all and, relatedly, no indigenous animal life either.
Much of the activity as at night. As I mentioned, this year is a new moon, so at night, it will be pitch black, revealing more stars and galaxies in the sky than you can hope to count in ten lifetimes. There are very few formal rules, so it's a true test of anarchy. Despite there being around 35,000 people this year, it's easy to find yourself alone: the encouraged standard is laissez faire, so while you're free to do whatever you please, the flip-side of that apathy is that there's nothing you can do to "be interesting" — you are simply yourself. Also, there is no commerce allowed: the prevalent philosophy is a gift economy wherein you are allowed to give things to other people — however, there is no obligation to give anything away as in communism, so you've got to play nice with others.
My project will be one that anyone can ride, so I need to get people interested enough to ride it on their own. This is where you come in.
I'm looking for musicians to compose music for the vehicle. Thematically, I'm simply looking for sound to attract people and entice them to stay. The nature of the vehicle and the interaction of the riders will involve synchronized motion (FYI, bicycle pedaling is typically comfortable between about 40 and 90 rotations-per-minute) as well as agreement, teaching, learning, dialog, conflict, and argument. Feel free to interpret at will.
I plan on including a track of my own that I'm tentatively titling "New England Dusk." It'll be some combination of simulation and edited outdoor recording of the sounds of dusk around here … rather, the version of dusk _I_ remember … spring peepers, crickets, blackbirds, crows, and probably some cicadas. I figure it'll seem familiar yet wildly out-of-place at the event.
The only formal limitation I'm placing on content is that it include no lyrics: that is, instrumentals, or non-intelligible vocalizations are okay, but I don't want the songs to tell a story in words. I'm asking about 7 people to submit a piece and I've got 60 minutes total, so while any length piece is appreciated, a 50-minute masterpiece might not be included. I'm going to be using an MP3 player and I'll do my best to maintain pristine fidelity, but the format is limited. Also, the final output will be _monophonic_ so differences between stereo channels will be completely lost. Finally, keep in mind that the sound system will have limited capability to reproduce low frequencies and it won't go very loud (typically around 1 watt [which is louder than you'd think.]) I'm using car-stereo speakers, so as a reference, fidelity will be similar to a good quality boombox.
I had originally wanted to synchronize each song to a particular light pattern, but I decided to drop the idea because it would be too hard to do with the parts I'm working with and because it's a nightmare of organization: setting deadlines and making sure I have time to compose a light show — yuck. Thus, my absolute deadline for getting music in place on the vehicle is sometime in late August. However, I'd appreciate it if you can get back to me with something by early July through August 1 (at the latest) … adjust as necessary to fit your own procrastination scheduling.
Please let me know if you'd like to help out or if you've got any questions.
More frame welding stuff
Posted: 2005-May-26 Filed under: Frame, Projects, The Bike With 2 Brains Leave a comment »I built the bent frame parts (the overarching parts) and welded them in place. I also added a cross-piece between the front unicycle forks. I welded the rear shelf in place and welded on the backs of the eyes. I used the sheet metal from a junked washing machine. I welded pipe angles behind the eye holes to house the LED's to light up the eyes. I created the pupils by welding a large washer onto a bolt head. I also installed mounting points for the seats.
Buy paint
Posted: 2005-May-24 Filed under: Frame, Projects, The Bike With 2 Brains Leave a comment »I went to Paint Masters (3327 Brighton-Henrietta Townline Rd.) and bought primer and sandpaper. According to them, I should apply the etching primer then either apply the fill-primer while it's wet or let it dry then very lightly sand it before applying the fill-primer. I should put on a couple coats of fill-primer and sand it with 320-grit paper. I'll need to sand off all the rust on the metal first, though, which could be a bit of a pain.
Buy more miscellaneous parts
Posted: 2005-May-24 Filed under: Lighting, Projects, The Bike With 2 Brains Leave a comment »I bought some milky-clear polyethylene tubing with a 1/2" outside diameter and a 3/8" inside diameter. It's easily large enough for lights and wires, and I decided on terminating it with 3/8" steel pipe which has an inside diameter that snugly holds the polyethylene tubing. I went with fender washers, 3/8" bolts, and pipe clamps to make the pupils of the eyes.
To connect the light tubes to the electronics, I went with DB-25 connectors with hoods. I should be able to crimp the tubing into the hoods and make a reasonably weather-tight fit.
Trying the Joule Thief
Posted: 2005-May-22 Filed under: Power Source, Projects, The Bike With 2 Brains Leave a comment »I found a circuit at a website called the Joule Thief. It's a nifty LED driver circuit that can allow an LED to be driven from a nearly dead battery. I figured it would work to boost the voltage from the generators I had but I couldn't get it to work with my limited knowledge (and lack of caring to figure out how the circuit really worked.) I suspect it relies on the nature of LED's to oscillate properly.
I got a couple bigger 12-volt motors from the electric cars for kids to drive around in — all from the trash. The smaller one can source 8A at 0.5V or 4 watts, and the larger can source 9A at 0.6V or 5.4 watts … both at 3,100 RPM.
First riding test
Posted: 2005-May-19 Filed under: Frame, Projects, The Bike With 2 Brains Leave a comment »I added the rear horizontal support and the one that goes across the middle of the bottom of the seat. I got it all assembled and put the pedals on and laid a couple 2×4's across to sit on. Freewheelers (1757 Mount Hope Ave) is at the end of my street so I took it there and the owner Roger and myself tried it out. We could only get it to run backward — it seems the trail on the rear casters isn't enough to allow them to swivel.
I modified the forks for longer rake by cutting notches, bending the forks, and welding it up. Roger and I tried it again. It sort-of works: it's very difficult to control. If you get going okay, you can stumble a little and it tends to spin around to do a 180. I kind of liked it for that.
I had to fix one of the forks so it wasn't bent so much because one of the tires was actually hitting the frame.
