$30 Harbor Freight Solar Node (Meshtastic or Meshcore)

The Lowe's Harbor Breeze spotlight is discontinued, so it was time to move on. I found this neat little spotlight, which seems to be a smaller version of the Harbor Breeze at Harbor Freight. Go figure, harbor in both names ;-). The nice thing is that it's well designed with an inner and outer box, so any water that makes it into the box runs out and the inner box stays dry (at least so far). It has a nice flip switch and simple removal of two resistors allows you to use the existing charge controller. You can use the RAK 190001 board or you can use the cheaper SEEED NRF52 version.

BOM for a inexpensive node:
* HF solar spot light $9 (https://www.harborfreight.com/40-lumen-8-in-solar-led-black-finish-spotlight-57704.html)
* Seeed kit $14 (https://www.seeedstudio.com/XIAO-nRF52840-Wio-SX1262-Kit-for-Meshtastic-p-6400.html)
* an antenna kit $12 (for 2) https://a.co/d/bwsZ4mZ.
* charging unit $8 (for 10) https://www.amazon.com/dp/B08DNK398S

So $30 for a solar node is pretty goo
