The IPM is not finished yet, I would like to add a number of additional features, if time and motivation allow for them:

• Over-the-air (OTA) programming using the web page
  • Currently the front end can be updated by uploading a new index.htm via the web page, but the flash memory cannot be updated yet, this is technically possible however
• Configure Wi-Fi and access credentials with access point (AP) mode
• Make something useful with the short and long presses of the button, for example:
  • Short press: toggle between the stats and an "analog style" counter on the OLED screen
  • Long press: Wi-Fi configuration mode
• Design and order proper printed circuit boards
  • The perfboard is kind of challenging to assemble, but the eBay components would stay as they're annoying to source individually

I welcome any contributions to the source if anybody's motivated, maybe I can motivate contributions with free PCBs, hmm...
