Where you at?
Probably the most common phrase ever uttered on a cell phone. Competes with “You still there?” of course. 🙂 Anyway, back to the show. I built myself an Arduino-based GPS receiver last night. I used the GPS Logging Shield from … Continue reading
prepping for Maker Faire
I dragged out the Arduino last night. It had been some time since I’d set up any circuits, and I wanted to get back in the game, so to speak, before going to Maker Faire. I have an abbreviated set … Continue reading
CNC plans on hold
I will continue researching CNC software and firmware, maybe build out my CNC Etch-a-Sketch like I’d been wanting to. I don’t know if the Ladyada Motor shield can juice the motors up enough to drive the EaS, but I can … Continue reading
Sidereal time
The stars rise about 4 minutes earlier every day, making them seem to march ever-westward across the sky. I received the gift of a real-time clock (RTC) circuit last week, and it got me to thinking about how to convert … Continue reading
Temperature Differential sensor
I plan to construct an Arduino circuit which will read two temperature sensors, and turn on a relay if the differential gets too large. This is eventually to be pressed into service on the dew heaters for the telescope. But … Continue reading
