CAN Bus Gateway

By |April 4th, 2015|COMPONENT BUILD|0 Comments

This week I have been working solely on the electronics apart from a few business meetings and some work on that commercial website I am doing.

 

Above image shows  the gateway to the CAN bus from Ethernet.
I finished the communication from the desktop through the gateway to the CAN bus clients. I also finished implementing the first client sketch for the motorised valves. Have found motorised ball valves in cr-05 configuration meaning they have feedback signals at closed and open state, not just motor wires. I can connect 5 of such valves to one Arduino using an IO expansion shield. It is […]

Update Mar 30

By |March 30th, 2015|COMPONENT BUILD|0 Comments

No cutting today.
I have weighed most components to double check with the calculated weight in the cad model. So far all is good, my entry doors were actually 7kg lighter than assumed in the model. Windows, steps, legs, baggage doors, tanks were pretty much spot on.

Finished the program (sketch) for the Arduino to be functioning as a gateway between Ethernet and CAN bus.
Works well, have included a page on the website about that.

I also have received my current sensors for the Arduino and will connect and play with them tonight.
I will use those current sensors to monitor if actually […]

Water Quality Sensors

By |March 28th, 2015|COMPONENT BUILD|0 Comments

Another couple of sensors arrived and I put the boards together to connect them to the can bus. They are sensors to measure
salinity and water quality of the output of our water processor to automatically stop or redirect the output if quality goes below a given threshold. The important bit here is where and how to mount them to get reliable readings. I will have to experiment a bit.

I have also ordered inspection lids for my water tanks since I have to open them to install my senders. They all have pre installed fixed level probes, but I don’t […]

Gate Valve Control

By |March 28th, 2015|COMPONENT BUILD|0 Comments

On the electronic front I have done a few more things.
Designed, built and tested the Arduino interface for the electric gate valves for my holding tanks using a relay board to create the reverse polarity switch for the motor wires. Works well including a reed switch telling me via a digital input that the gate is actually open.

Above image shows the gate valve with the reed switch, currently just taped to the body. Will glue it though.
below is a schematic of the wiring for the gate valve and the picture below that shows the actual relay board.

 

 

 

 

Solar Panels Arrived

I added a couple of pages to the website.
One about the 240V system and one about my first cut with a little video of the saw in action.

I have adjusted the saw perfectly square and will get a laser level tomorrow for the vertical adjustment.

The solar panels came today, so now all my components for the 240V system are here, the batteries, inverter/charger,
solar charge controller and flexible solar panels.

The cables on the solar panels are pretty long, I will have to shorten them in groups of 4 because the panels will be rather close and I don’t like the long […]

Receiving components and thoughts

Done lots of things, little stuff but lots. Today I picked up the steel for the trailing arms and the rods to make the jig for the suspension hangers. Will talk about that later .. The trailing arms are made from 65x65x5 C450 galvanised steel (Duragal Plus).
I could get away with 4mm but decided to have more safety margin, I have a 6t rated chassis after all, so the trailing arms should not be the weakest link. I push comes to shove I can fit an air over hydraulic unit instead of the electric over hydraulic unit and go […]

Security Cameras And Recorder

By |March 10th, 2015|COMPONENT BUILD|0 Comments

Right now I am still waiting for some CAN bus shields and digital temp sensors, but they are expected soon. Yesterday my NVR arrived (Network attached Video Recorder). I did put in an old SATA drive (Will use an SSD in the production version) and the thing was working very well only after a few minutes. The IP camera is great, good image quality and very sensitive in motion detection. The recorder starts automatically with motion detection from any of the connected cameras.

Although I am very happy with the quality of the camera (both built quality and image quality) […]

Lab Testing Electronics

By |March 10th, 2015|COMPONENT BUILD|0 Comments

I was working on the electronics for the TAS (Teutanic Automation System). I have tested most individual signal types on their own and now have mounted all the different board types I am using on a perspex plate to make a bit more solid test environment. I have too many individual pieces to just make it work free air on the desk. Not that I mount all the devices I am using, far from it, but enough of each type to test all the variations of the required control functions. Since we talk automotive electrics/electronics we deal mainly with […]
