I’ve read through both articles and will continue working on them tonight and this afternoon but wanted to send over what I have worked on so far.
Speculative Bill of Materials
- I am using the NodeMCU but you can use the Feather Huzzah ESP8266 with stacking headers (also available preassembled)
- I am using a 4 Digit 7 Segment Display from the ELEGOO UNO Project Super Starter Kit but you can also use the 4-digit 7-segment FeatherWing display
- Soldering iron and solder
- Neopixel Jewel
- Stranded wire
- Perma-proto half size breadboard
- Flush diagonal cutters
- Wire strippers
- Multimeter (optional but handy for troubleshooting)
- Third hand tool
- Desoldering braid or solder sucker (optional if you’re flawless)
- Micro USB cable
- USB power adapter (optional)
- 1/4″ – 1/2″ MDF (4-6 layers): laser cut
- Wood Glue
Project Proposal + Circuit Diagram
I decided to go with the bookend with an LED display that shows how long you have until your next meeting / event. The display would sync up with your Google calendar using IFTT and connecting with the Arduino IO. The plan is to also add a neopixel jewel to turn on when the value in the display is equal to or less than 5 as an alert of you need to be ready to do your meeting.
If I can figure it out I would like to make two so there would be one for different people. I think I would need to create another circuit using a different ESP8266 board.
