The Backcountry Logger is a portable microcontroller-driven device that collects temperature, air pressure, and altitude data, and shows graphs on a built-in screen. It’s intended for hikers, climbers, skiers, and other outdoorsy folks who want to geek out with environmenal…
Hooray, the v1 Backcountry Logger boards have arrived from the PCB manufacturer! This time I used Dorkbot PDX, and the elapsed time from the ordering cutoff date to board delivery was only 12 calendar days. For $5 per square inch, with…
Shrinking a design as far as possible can be an addictive hobby. Even though PCBs for the first backcountry logger design aren’t yet back from the board house, I’ve been busy working on a revised version that’s just 1.9 x 1.1…
Sometimes it seems like there are a million different LCDs you might use with your microcontroller project, and deciding on one can be hard. Once you’re ready to move beyond a basic text display, you’ll find graphic displays have a…
The Tiny CPU board design is now off to the board house for manufacturing. The three week wait begins. Somewhere during that time, the Backcountry Logger boards should come back too. I selected Seeed Studio’s Fusion PCB service, because it…
Whew! It was a big job, but I finished the Eagle board layout for the new Tiny CPU, using the Max II CPLD. The board is about 4×3 inches, and if your monitor has a typical 72 DPI, then the…
