DIY GPS device using Arduino Mega #Arduino #DIY

Thanks so much to David for sending in his GPS project to us! Check out more info here and here.

The direction indicator will point to the location corresponding to the latitude and longitude coordinates entered below. The distance is based on a logarithmic scale with more variability the closer you are. I held off on permanently marking on the case the specific distances in case I wanted to change the scale. The power button has a blue LED that indicates when it has a GPS fix.

Mechanical Decade Counters – Small Size – Pack of 5: Click click click – oh pardon me I was having fun clicking away on my mechanical decade counters. Each order comes with five individual counters. They’re snap together so you can connect as many or as few as you’d like. Each one has two buttons – an up counter and down counter. Once you get to 9 it circles back to zero. On the back is a PCB with 11 contacts – one common and then 10 that are shorted to the common one by one as the counter goes by that number. Read more.
