I completed assembly of V1.1 of the sensor board. This version revised the power circuitry.

I applied techniques learned from the first version's assembly.

I placed the BGA power IC first. A thin layer of flux was applied to fix it to the board. Then the remaining SMT parts were placed. The boar...

I obtained Rollei IR film for my Mamiya C330 TLR in January and had been waiting for a good sunny day with the trees blooming. Finally in early April mother nature obliged and I was able to get out for some mid-day shooting.

I took pictures at the reservoir in Hopkinton State Park. Then I retu...

I got cocky with the second step in my temperature sensor project, IoT Plan.

I assumed I finished the design of the power circuit, in retrospect I must have set it down to return to later. I did not connect all the required pins for the power IC and designed a new version. Hopefully the next tim...

Like many computer game players I am trying my hand at writing my own.

I attended a game developer's meet-up in February and have another scheduled for April. I had nothing to show at the first meet-up as I was just getting started, but the second has proven to be a good motivator and I hope to s...

My mother came across a picture of me at graduation in 2010, and I am posting it here for posterity.

I have fabricated a wifi temperature sensor for my IoT project, IoT Plan.

The sensor board uses an ESP32 module for its core functionality: controller, wifi and temperature sensor. I paired it with a buck-boost voltage regulator that can be supplied by battery (3V) or micro-usb (5V) source. A 4-...
