A different kind of Initial Coin Offering

IMG_6880.JPG

I have 2,500 in shinny new $1 coins that I need to get rid of. I want to give them to you… if you can come up with some way to creatively use them.

You have until midnight December 31st to tell me your idea. The winner will be announced on New Year’s Day. If you win, you will have 30 days to come pick up the cash in NYC.

Some facts about the coins:

  • 100 rolls of $25 each
  • Weigh almost 50 pounds
  • Stacked like flapjacks would make a tower more than 16 feet tall
  • Laid edge-to-edge would stretch father than a city block

I am looking for a project that:

  • uses the coins as coins rather than money
  • can be completed quickly and decisively
  • is a concrete plan of action rather than an abstract concept
  • will make people say “That is amazing”.

I’ve intentionally avoided adding rules to encourage wild and unexpected creativity.  I’m looking forward to see what you come up with!

Marketizing Zipcar

There are normally lots of Zipcars near me, but looking at Thanksgiving day things look pretty bleak…

SNAG-0001.png

If I want a Zipcar on Thanksgiving, my only option is to wait and hope someone cancels their existing reservation (which for other reasons will all likely happen 3 hours and 1 minute before the reservation start times).

Maybe a little marketization could fix this problem and make everyone better off….

Capacitive Coupling Casestudy: Programming The Public Radio without removing it from its sealed shipping box

2017-03-18 13_12_32-the public radio

You’ve probably heard about the refreshingly simple Public Radio (TPR). There is no tuning knob needed since your TPR magically knows your favorite station straight out of the box.

Like most magic, this illusion of simplicity involves a lot of work behind the scenes. Each TPR has to be custom programmed by hand, assembled, and then lovingly packed before being shipped to your door. If only there was a way to program an assembled TPR without opening the sealed box…

The few useful comments are lost in the noise.

A Quick Test for Crappy WS2812B Neopixels

TLDR; If you see ink flooding around the die when you touch a Sharpie to the face of a Neopixel, you should probably throw away the batch. Disturbing video example after the jump.

I recently found a huge lot of WS2812B Neopixels on Alibaba for $3/meter, which is about 1/2 the going rate in China and about 1/8th the price for similarly spec’ed strips on Adafruit. So I bought a lot (both meanings) of them. A NeoPixel is a NeoPixel, right? How bad could these NeoPixels be? Very bad, it turns out…
