AgOpenGPS Picture thread

[MattR]

After reading threads on here and elsewhere I have decided to go down the agopen route. I have no previous experience of guidance systems, or of electronics, and in general am not particularly "tech savvy" at all.

My plan is, for now, to put together a basic lightbar system with which I could, at least, spray an autumn herbicide (for various reasons I have not tramlined this year's wheat), and try to get acquainted with the software etc. Then maybe fit a steering motor and associated gubbins over the winter to have a proper auto-steer setup in the spring.

To this end I have purchased:
a Panasonic toughpad
an Ardusimple F9P module
a ublox antenna (awaiting delivery)
an IMU

Just to check, to connect the tablet to the GPS module, I need a normal USB micro-b cable like an android phone charger? And that goes where it says "POWER + GPS" on the board? Then when the antenna arrives that will screw into the brass threaded bit I take it.

What about the IMU, do I need it at this stage or not until (if) I go full auto-steer?

Something I can't see much info on is how people house all these intricate bits of electronics. In your post above @Andy26 does the solid looking box on the right come with the PCB? Or did you get it 3d printed specially? What would people advise for the Ardusimple board for now? There are several websites selling plastic "enclosures", is there a particular one that fits well?

Sorry for the somewhat basic questions, this is not my area of expertise at all!

Tablet + f9p + antenna = light bar. IMU no use at this point. Connections are right.

Professional SimpleRTK GNSS Case - Compatible with ArduSimple SimpleRTK2B (v1.0) RTK GPS Board w/ u-blox ZED-F9P by simolabs

This professional GNSS case is designed to be compatible with the SimpleRTK2B (v1.0) from ArduSimple that is powered by a u-blox ZED-F9P chip for cm-level RTK positioning. The case should fit all three versions of the ArduSimple RTK board, including the version with Arduino Headers pre-soldered...

@MattR so you have the corrections right.
IMU don't worry till you upgrade to autosteer unless your spraying on the side of a mountain.

Just put the F9P in a 'project box'/enclosure and use grommets to seal the two holes you'll need to make in the box.
To mount the F9P in the box use some PCB mounting posts like these:

If you get a PCB from myself it will come all mounted in either of these boxes:

The one on the right is 3D printed, one on the left is a metal Hammond Enclosure.

That's great, thanks for the info @andyinv and @Andy26 . I didn't realise you supply PCBs etc Andy26, I might be in touch in due course if all goes well with the lightbar system

Nice to look at other people's installations and get some inspiration.
I'll include a few pictures of my own installation. The tractor is a NH TS130A delta. Location: Finland .

Baraki valve on top of the engine under the hood. Unfortunately I don't have a picture with the lines installed.

Was installation, homemade flange for the sensor. It's threaded and locked with threadlock in the hole for grease nipple. And yes there's a grease nipple in the flange.

Ram mount on the tablet, it's fixed with a sturdy double-sided tape to the tablet. The lower ball is made on the lathe because I needed it promptly.

Red one is the on/off switch for AOG cuts power to the system so it will release the steering wheel if all else fails.

Assembled PCB.

Here's the main task for the system, seeding and interrow cultivation.

Enjoyin the straight lines.

Love the custom PCB, Is that a dongle in the Ethernet port?

No cytron, so SMD motor controller?

Ah. that fieeling...
Latest version has K-turn. Tried it?
I only tried it in the simulator, and it seems to work fine.

Bypass the operator presence switch, let agopengps drive the tractor, and you'll can spend the day in the pub!

if i can get agopen to work the hms i can have a hours kip while it runs out of seed

Thanks, when I started to design it there was no all in one board, might have used that one otherwise. No dongle but I use an M12 connector for ethernet, it's a bit sturdier than rj45 in a tractor cab.

It's not a motor controller really but there's three high-side drivers for Baraki's valve. One for the locking valves and two for directional valve.

bit of luck it should be a lot easier on the 7400
there is a separate button on the armrest that i can tie into then connect the ardunio from agopen to the button via a relay. @Andy26 said he will help with recoding the ardunio to output for 2 seconds to work the hms

Can probably just set in the Hydraulic lift config part in AOG, like this:

This will then then trigger the relay for 2 secs, which can use to mimic pressing button for 2 secs.

First few steps taken. Secondhand tablet, software downloaded and a holder made from steel from under the bench.
