As each year passes and my to-do lists get longer, I have to accept that I will die long before I will get to make and do everything I want to.
Here are some things that I probably will never get to, but maybe you will? Don’t let the crackpot-stream-of-consciousness-style throw you, I believe most of these ideas could actually be successful and profitable… with some work.
Let me know if you are truly interested and I will try to share any effort I’ve already invested to give you a head start….
It doesn’t matter which side of a resistor goes to which connection, and sometimes switching them around can make a board much easier to route. Same goes for equivalent IO pins on a microcontroller and lots of other cases. Here we see what a big difference a little pin swapping can make, and how to give the TopoR auto-router the freedom to swap your pins for you.
There is no intrinsic value to a BitCoin because it is an anonymous IOU written by no one.
I want you to give me half of your doughnut.
I can offer to give you a signed IOU that says “Josh will give the holder of this IOU 1/2 doughnut”. The more you trust that I will actually honor the IOU, the more it is worth to you. You might even be able to trade that IOU to someone else for something that they have and you want… assuming they also think there is some chance that I will honor it.
Instead of writing the IOU, now imagine that I write a program that generates random sequences of letters on my computer. I let that program run for a very, very long time until it happens to generate something like “IOU 1/2 doughnut”. I print this out and I offer to trade it to you for 1/2 your doughnut.
YOU: So if I take this note, someday I can give it back to you and you'll give me something yummy?
ME : Nope. This is not an IOU from me. It was randomly generated by a computer.
YOU: So who owes me the 1/2 a doughnut?
ME : No one! But it took the computer a really long time to generate this note at random!
YOU: If there is no one who will pay me back, then why would I ever accept this note?
ME : You can try to trade it to someone else for something they have and you want!
A dollar is an IOU from the government, a BitCoin is an IOU from no one…
There are normally lots of Zipcars near me, but looking at Thanksgiving day things look pretty bleak…
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….
Why are we humans still wasting our time doing a crappy job at manually routing printed circuit board traces? If a computer can beat the best Go player on earth, surely it can route a mess of traces better than idiot me!
Let’s try out a few of the latest and greatest auto-routing programs to see how useful they are routing my new board! Continue reading →
Everyone loves blue LEDs and everyone loves coin cell batteries, but if you want to power a blue LED from a coin cell you will need some help. Here is a super-cheap and easy way add a to boost your LED voltage with only an additional capacitor & diode, and a little software.
