1/ My #IoT Telegraph - A thread:
At the end of my talk @NottsTechfast on "The History of IoT", I closed with a show stopper demo. I built a homebrew Telegraph from wood, nails, spring, wire and other components I had around the house. @msdevUK, @MSIoTDevs@MicrosoftIoT#MVPBuzz
2/ The basic circuit diagram of the Telegraph is shown here. The Transmitter side has three 1.5v AA Batteries which connect through the rudimentary Morse Button out to an Electromagnet at the receiver.
3/ The receiver side has two 1.5v AAA batteries connected to three nails. The angled nail is attracted to the Electromagnet when it's activated, closing the circuit and activating the sounder.
Sadly the only way to keep any form of stability in my 1 month old @Surface_UK... Yes that's an ice block... Yes... A) I'll be resetting it (backing it up as I type). B) I'll be filing a service call if that doesn't work. C) yes, that's an ice block! Haha
The only thing I'm doing right now is using @MacriumReflect to image the SSD...
Without the ice block... Even at roughly 30% CPU, throttling occurs and my CPU runs down at 0.6 - 0.8GHz and everything is laggy as hell. The only way to work around that is to keep flicking between power modes. But even that fails after a while.
