From Mark Smith on the Surf ‘n Circuits blog:
Adding IOT to the Nixie Tube Clock. A clock that provides the estimated time of arrival for up to ten destinations
The ETA Nixie clock is programmed to display the normal time and up to ten different ETA times that are easy to identify and visually stimulating. The current time is displayed for 5 seconds (i.e. 8:41:38 AM), then up to ten different ETA destinations are displayed for three seconds each before the cycle is repeated. The current time displays all six digits including seconds. The ETA locations are numbered and display hours and minutes without seconds helping to distinguish between them. In our house, the ETA to work is ETA number 1 (i.e. 9:07 AM) and the ETA to school is ETA number 2 (i.e. 8:58 AM). Lots of other options are possible with custom programming of the Raspberry Pi to meet your ETA requirements.
surfncircuits has shared the board on OSH Park:
There is a new PDX Raspberry Pi and Arduino meetup organized by hosted by Mitch Bayersdorfer coming to Portland on Saturday, April 7th:
• What we’ll do:
Part social and part build time, this meet-up is for those
• What to bring
Computer. Raspberry Pi and/or Arduinos if you have them. Projects that you want to share. Items for the “parts luck” swap bin.
• Important to know
The shop where this is held only has space heaters – so please dress warmly on colder days. On very cold days, we will forego building and have a social in a heated space, if we can’t find an alternative spot.
Raspberry Pi FPGA HAT designed by Eric Brombaugh:
The icehat is a small (Raspberry Pi Zero-sized) board with a Lattice ice40 Ultra or Ultra Plus FPGA and three Digilent-compatible 8-bit PMOD receptacles.
Sergey Kiselev designed this I2S Audio pHAT:
This is a Raspberry Pi Zero pHAT form-factor I2S audio interface board based on a Cirrus Logic (Wolfson) WM8731 audio codec. It provides line input, line output, headphones output, and includes an on-board microphone.

I’ve unfortunately had to flip the bill for my two past surgeries and my on going cancer treatment… and as you can imagine, I’m running out of cash.
If you like my content and/or have found my published projects interesting or useful, please consider sending me some spare change and I’ll be ever so grateful.
