 +===== Trailer =====
 +For when you have extra groceries to buy or ... ? Taking a car infrequently is pretty easy though.

 +  * Dog box, collapsible.
 +
 +Or child trailer. But sucky part is storing it. Somehow mount to ceiling.
 +===== Notes from Johnson Light Show =====
 +Vixen or xLights
 +  * Seem to need to use an OS and external controllers. Can be as cheap as Raspberry Pi Zero
 +
 +Screw connectors for waterproofing and strength.
 +
 +
 +Wemos D1 Mini is awesome. $4 each, and you get wifi, 4mb of flash, free webserver, etc. Wow. 
 +
 +Also want to use FastLED. They do dithering and lots of cool patterns. Don't support RGBW, unfortunately :-(
 +  * {{youtube>​fjoDkqoU5Fk?​medium}} with yellow pool noodle. Free code!
 +  * {{youtube>​3zQ8qC1KQgU?​medium}} Also free code! And construction!

 +He uses Ray Wu's Alibaba page: https://​www.aliexpress.com/​store/​701799. But prices aren't that much different for 5V led strips than ALITOVE on amazon
 +
 +====== Ultraviolet UV =====
 +BBlack lights and tanning beds and UV leds all put out 320-400 nm UV light. (UVA).
 +
 +Pretty sure more UV light is put out during the daytime w/ the sun than coming out of a black light, but want to avoid it long term. Also, avoid pointing it in your eyes / exposed skin too much.

 +  * Need to have really accurate timing estimate of LED strips because it stops delayMicroseconds() and delay() from working right. I'm off by a factor of two somehow 
 +    * Really helpful to have an oscilloscope / logic analyzer for this, as you can get accurate timings of everything very easily just by pulsing a pin and commenting out everything except each section you're timing.

 Might not be able to get much done in Hillsboro, but at least it's a thing. Bike lanes help a ton, so I'm not complaining really, but it's **really** important to stay aware. Might not be able to get much done in Hillsboro, but at least it's a thing.

   * A constant (even bright!) small light pointing forward is indistinguishable from a street light far away and can be hard to see at off angles. The larger the emitted light looks, especially from side views, the more chance you have of being seen and recognized as a cyclist.   * A constant (even bright!) small light pointing forward is indistinguishable from a street light far away and can be hard to see at off angles.

Pointed-up spikes {{:​everyday:​pasted:​20190104-121831.png}} are a little much for me, but rows of ping pong balls are kinda lame.

 +    * Kinda like the middle one, but it's almost too anime.
   * "bang bang" (on off) blinky lights don't convey distance very well. Our eyes need time to place something. So an oncoming car might think you are farther away than you are and cut in front? Plus they are quite annoying, not so good either. ​   * "bang bang" (on off) blinky lights don't convey distance very well. Our eyes need time to place something.

 +Looks like the pros use clear plastic infused with barium sulfate: https://​www.prnewswire.com/​news-releases/​light-scattering-grade-barium-sulfate-248191361.html. Will see what it's like at TAP plastics.

 +I liked the polyethylene at Ace. Kinda milky
 +
 +TAP plastics, they have:
 +  * LED Light Panel Sheet, thin, easily bendable and probably adjustable. https://​www.tapplastics.com/​product/​plastics/​plastic_sheets_rolls/​led_ligh_panel/​598

 +
 +  * {{youtube>​KqYq21fSfRU?​medium}}
 +    * Huboptic makes good diffuse light masks, but pretty sure they'​re all with EL panels (somehow addressable!,​ probably with lots of small wires). Nice work, but too dark for my needs. But they do have some LED ones too....

 +=== Hot glue ===
 +The usual craft stuff has a low "​softness"​ temperature of 130F. Also our glue gun only goes to 280F. Increasing to 400F will help grippiness, but it'll still be soft in sunlight. So will call hot glue folks and see what they recommend / say.
 +
 +Also best to heat up the metal or whatever, apparently, before connecting.
 +
 +
 +Is 3M tape better? As long as it's somewhat easily removable. Probably a lot less frustration for end user over buying a hotter hot glue gun.

 +I'm leaning towards much larger (1"?), lightweight tubing that I wrap/glue with outdoor fluorescent yellow flagging tape. Good source for cheap ($1.50 + $3.50 shipping). http://​smithsafetysupply.com/​fluorescent-glo-flagging-ribbons/​

 +Hard to find tubing that is outdoor proof and not transparent and cheap. Flagging tape it is!
