= Questions =<br />
<br />
* Do LiFePo4 batteries off-gas or can they be sealed?<br />
* Is there existing infrastructure where we can mount stuff<br />
<br />
= To buy =<br />
<br />
== Modem ==<br />

== Router ==<br />
<br />
Is there a good OpenWRT router with USB? USB 2 is probably fine. Possibilities:<br />

<br />
== Battery ==<br />
<br />
One of those 12V LiFePO4 modules that look like a lead acid battery and includes BMS? Downside: Monitoring state of charge from voltage is hard but we probably don't need that, just low voltage cut-off.<br />

<br />
== Solar charge controller ==<br />
<br />
* Just one of those MPPT things of ebay/amazon<br />
* Also maybe we could try to make one of the [https://libre.solar/hardware/mppt-1210-hus.html libre.solar devices] though the microcontroller can be scarce (mouser has them right now)<br />
<br />
== Solar panel == <br />
<br />
We want a flexible panel. Maybe 100 W.<br />
<br />
== Mounting ==<br />
<br />
Need to sync with folks there.</div>Juul
