“Google called, and josh.com needs more cats.”
So today we look inside these amazing cats that can somehow keep on wavin’ using less than 15 microwatts (!) of power. If you are into either ultra low-power or extreme design-for-manufacture, the you will want to see what is inside of these guys!
“What I can not create with an Arduino, I do not understand”, so we then proceed to recreate a lucky cat under Arduino digital control.
The am335x ARM chip in the BeagleBone Black has a Real Time Clock hidden inside that you can use to have the board spontaneously turn itself on anytime in the next 100 years.
Here I present a new utility to manage that built-in clock from the Linux command line, and explain how to use it to keep time, shutdown, software power cycle, and more!
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.
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.
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…
Remember when almost every image on the internet was trump?
With trumpWAP, we can make the web great again. This is huge.
Plug in the trumpWap and on day-1 you’ll get between 20% and 90% more trump (depending on your browsing habits). It’s that simple.
Continue reading for more examples of trumped up websites & apps, a perfunctory video demonstration, and info on getting your own trumpWAP!
