Going to pull it with that "Super Duty'?
No, it's not mine, plus it doesn't currently run, and he can't figure out why.
I think I have my POSpi up and running. I'm using ODOO as the POS, Zoneminder for video surveillance, NodeRed with MQTT for remote sensor monitoring. Since I'll be using coolers loaded with ice to keep food cool, I'm going to build some wifi enabled temp sensors that will monitor the temp and report them to NodeRed. Data can be displayed on the screen in the trailer, and alarms can sound if they get too warm. The sensors will be battery powered with a solar panel backup/charge.
I hit a wall yesterday when working with Zoneminder when I found that the cameras I have, are 2.4ghz only, and setting up the RaspberryPi as an access point, I can only run it as either G or A, but not both at the same time without a bunch of configuration that isn't known to be stable.
Jumped on Craigslist and quickly found a guy selling a pair of dual band routers for $15 for the pair. Ran out and got them, and now my cameras can connect to it, and the RPi is connected via ethernet to it. The wireless on the Rpi will connect to my local Wifi when it's within range, so it can be backed up and worked on when it's home. The routers will also provide connectivity to the temp sensors and the tablet we'll be using for order taking.
Commercial POS $1000+
My POS with surveillance and wireless ordering under $200. Most expensive parts are the two 12" 12VDC monitors that I have yet to order. The cameras were under $9 each, the Rpi under $50 and the Argon case was around $50 with a 500GB SSD installed.
While I was up when the trailer was getting welded, I got to get inside and do more poking around, which I didn't do much of before because the cinderblocks it was on down in MD didn't feel that stable walking around. I discovered that there's a "Bain Marie" commonly called a steam table. It's a large 2 bay one that's heated with propane. We thought we'd have to buy one, but it's already built in, we just need the pans that fit it.
Also discovered that the coffee machine is propane heated, but we don't know if we're going to use it or not. It's missing the lid and so far we haven't been able to identify it to even know if we can get parts for it.
I also thought it didn't have a grey water tank, but it does. But I need to figure out a drain for that, before we attach the two trailer together. Weather permitting, tomorrow I'm back up there. Plan is to flip the donor trailer back over, cut off all square tubing off and the fenders. Run all the wiring. That will take most of the day. Plus, we need time to fly the drones around.
