I am not a nudist, but I am taking vacation days this week and I decided I will not do laundry. So I made the tactical decision not to wear underwear and wear old bummy jeans with holes in them, and working and sweating all day I had a bad case of chafed inner thighs..so bad that by now I dug into my stash of bikini briefs to hold things high and tight to allow my thighs to heal. I mentioned this to a friend and wondered how our ancestors who only wore loin cloths managed chafing... all I got for an answer is that "now you know why you should wear underwear". So I mentally went through examples of people who DON'T wear underwear, and they are all remote in time or place, except, convenien

If you are like me, you can't wait for a new probe to get to one of the planets and send back images and telemetry. Even though this is happening at a quickening rate, it doesn't feel quite fast enough, and then the data is filtered and manipulated for 'clarity'.

So it occurred to me the other day that there must be a better way to do extra-planetary exploration and bring that experience to just about anybody who wants to participate. Today we are almost to a point with automated drone technology that we could send many thousands (or millions) of cheap autonomous drones to Mars to blanket the planet -- with each drone assigned a small section of grid to explore in detail. These could be

I (and some coworkers) have created a bot around a raspberry pi 2. It's working well. However, I would like to add a few proximity sensors to it. I've got 4 HC-SR04 proximity sensors which work well. The problem is that each one takes up two GPIO ports, and that doesn't leave a lot for other necessities.

My initial thought is that I should be able to control a multi channel switch with a minimum of 3 GPIO ports, 1 to switch channels and 1 for the VCC in to the sensor and 1 for the echo. Then I can have a channel for each sensor and switch inputs/outputs in a round robin fashion.

Does anybody have experience with such a setup?

Are there any favorite switch controller boards?
