FreeBSD on the go...

I am still plodding away at this project. Instead of focusing on the headend I am working the backend.

I used a Group29 deep cycle battery in a Marine Battery Box. Inside I placed an APU2 with Atheros Wifi and Ublox GPS module.
Using SATADOM with 90degree adapter. I have a 2TB mSATA for possible mobile NAS usage.
Using gpsd and gpxloggerd for GPS and dnsmasq and hostap on the wifi card.

Here is the antenna I just received:

404

I really did not want cellular antennas but for the price I had to buy it. Will mount this on a 21" long SS pipe nipple with flanges mounted to Truck Toolbox to avoid drilling into the chassis.
Battery box/APU2 located under Truck Toolbox in bed..

The stainless pipe will be a "Mast" in nautical terms. It might house more than just an antenna...
 
I finally firmed up the front-end.
Havis 10 Inch HDMI monitor with Havis keyboard. Single arm mount.

I have not firmed up the backend. No HDMI on APU2 makes it an outlayer.
I got a Adlink MX211 but it has DisplayPort and I need HDMI. I have Nexcom Nice50 but it uses 24V. Still going through the options. maybe Lanner NCA1010B

Reviewing Lanner NCA-1010B fanless gateway box with Intel NICs

Quest for gateway machine with dual Intel NICs I, as well as my fellow Linux networking enthusiasts have grown to dislike any network hardware which has Realtek network interface cards (NICs). I had a personal problem with those; my Windows 7 installation refused updates when the gateway machine...

400mA MAX is what I am seeing as well.
 
I think I have settled on Jetway Pico-ITX in a nice compact chassis..
N2807 is really low power. I set freq at 498mhz. Plan to try single core operation.
I also have a N2930 model if too slow.

Using 32GB mSATA with ATH9K hostap and GPS via internal USB header.

Really hoping I can get eGalax Touch Screen working on the 11.6" Havis HDMI monitor. I prefer keyboard for setup only. Maybe flip out of way.

Mounting the Jetway under the hood in IP66 box. Antenna cables from mast running from bed mounted toolbox to under hood.
HDMI and USB cables for touchscreen running from engine compartment to cab.
 
Well I like the Jetway PicoITX board so much I bought a newer version. With J4105 Intel. I downclocked it to 800mhz and 4 cores only consumes <200mA idle, That is before wifi card and GPS.
I have never seen that low amperage. Even on ARM64.

I took a detour to build a battery box for two SLA batteries. I already own some PicoUPS but it requires 15V input. Should I use a step-up converter?
I have an old car laptop charger I thought about using.

The product I want is too much money.

OpenUPS

OPEN-UPS was designed to provide user specified regulated power output from a wide input voltage, battery backup, multi-chemistry charging and cell balancing in a single PCBA

Anybody use this device?
 
I ended up using a DC boost converter using LM2588s for the 17.5VDC to the PicoUPS-100. It only provides 3A though. Temporary solution.

PicoUPS-100 12V DC micro UPS system / battery backup system

picoUPS-100 12V DC micro UPS system / battery backup system for 12V automotive environments is a small yet powerful UPS (uninterruptible power supply) solution
www.mini-box.com

I mounted those boards to the side of a battery box I built for two 12V7AH SLA batteries to go under the hood.

Found a fuse box tap that I used for power. That way it is ignition controlled. Fused.

Nearly ready for computer. I settled on the Jetway JNP891 PicoITX. Set up hostapd for comms and need to add GPS module. I might mount it under dash. Shortest HDMI cable.

I will take a picture of the battery box. I spent way too much time on it considering how bad it looks.
 
I am looking on suggestions on hooking my truck to my home via WiFi.

Scenario 1.
Currently setup mini-pc mobile FreeBSD WAP with Atheros radio and GPSd. gpxloggerd providing coords. I want to have a GPS logging transferred to the home.
When I pull in driveway Wifi Connects and scp transfer log files to home fileserver with wifi..

Scenario 2.
Setup home WAP from Netgear ect.. and have truck as wifi client.
With the faster Intel wireless I am thinking of getting an 802.11ac base station.
I have completed my home network wiring and dont use wifi. It just seems ridiculous to tie ethernet to truck. I am lazy too.

Suggestions? Bluetooth might reach 15ft? Very small log files.

Just buy a Netgear wifi router, slap OpenWRT on it, and install on your home net. Then let the laptop that you carry in your truck connect to that. That's what I have, and my phone connects to my wifi as soon as I get in my driveway. It's frankly the easiest way to do this.

Then set up your transfer.

Just what's the problem with using wifi on your home net, anyway? It's not that hard to restrict wifi connections only to devices with known MAC's, like your laptop. OpenWRT and DD-WRT definitely have that abililty.

That might be the sanest advice you have given me. I am opting for x86-64 flavor on Lanner NCA-1010B. One of my original car router contenders. Full sized radio slot but half sized mSATA.
I always wanted to build a Devuan Wireless Access Point to see what I was missing.
So instead I will use Atheros 802.11AC module in hostapd mode on OpenWRT for my home WAP. Connect truck with Intel AX201 module as FreeBSD wireless client.

I think you need WPA-Enterprise for good restricted networks. But then you need a radius server for users.
MAC's can be spoofed. Its not really security.

I was thinking of maybe trying an open wireless network for just the vehicle but only have ssh exposed and use strong ED25519 keys. Part of the plan already for the scp transfers.
For offloading GPS logs on vehicle that will suffice for me.

Testing with FoxtrotGPS and it works. Moving map on a laptop.

Car-based router??? Now that's kinda insane, buddy.

I've seen buses that offer wi-fi on the go - the way that works, they got a phone with a data plan that is paid for from the bus ticket revenue. That phone acts like a modem. Then there's normal wifi hardware built somewhere into the ceiling. And that wifi is what the passengers' laptops/phones see and connect to, just like normal wifi at Starbucks.

You think general public has the skills and knowledge to do that? Crackers generally run scanners in specific locations. And it's just the first line of defense, next up is something that has far lower chances of succeeding: password-based authentication. Well, ED25519 keys can be used in addition to that, those two don't really fight with each other on the same AP.

Good router firmware like OpenWRT or DD-WRT allow you to fine-tune who gets access to your internal net (think VPN), and who should be given merely access to the Internet. And that kind of stuff needs to be thought through BEFORE setting up any hardware or software.

If you're setting up stuff just for the heck of it, that's fine, but don't involve sensitive data/users. Start with a simple use case where you can get stuff working, and then see what you can do to button things up neatly for work-related stuff.

BTW: DON"T DO OPEN WIRELESS NETWORK. This will invite random people to connect to the router and surf for porn and use up bandwidth.
 
I bought a Mobile AIO Computer for $40. It is a Forklift Computer. It is super rugged. Built in UPS with four 18650 batteries.

Runs a FreeBSD OpenBox Desktop with Touch Screen working OOB.

The CPU is Baytrail E3845. So I had to use FreeBSD 13.5 and drm-51-kmod for graphics.
