Motorised Ball Valve Control Unit

Another component I have been working on during the last days, apart from the plumbing I have done, is the unit to control the motorised ball valves for the heating elements as well as some valves installed with the water tanks.

The complete unit comprises two components, the relay component and the processor component. Above image shows the relay board with 16 relays driving 12 ball valves. The connectors are 5 pin plugs connecting each ball valve. Two wires drive the motor. Changing polarity changes the direction of the valve movement. The other 3 wires are used for the feedback […]

Main 12V Control

As part of the electrical work I was doing over the last few weeks I was working on the main switch component for the 12V supply. The main reason for such a switch component is the goal to minimise power consumption. Each control component like a valve control, dmx control unit, slide-out controller and any other component use power even on standby. Audio PC, video PC, cameras, NVR and other 12V units add significantly to an idle current which could amount to 3-5 Amp, which is almost as much as a small 12V fridge would use when running continuously, […]

Heating Plumbing

By |August 19th, 2017|BUILD, PLUMBING|0 Comments

Over the last weeks I have been doing some plumbing and also worked on electrical components apart from other things. I make progress but slowly, however I am still trying to get everything finished by the end of the year. I have my doubts though, because there are still many things to do with the commercial project but we would really like to get away after the Summer holidays and before the big heat.

The heater outlet in the living area. Originally I did not plan to use the Webasto hot water heat exchange heater units but I found them […]

Truck Upgrade

By |August 19th, 2017|BUILD, Uncategorized|0 Comments

I had planned upgrades on my truck for some time and had the components shipped from the US in the container I received with all the van parts. It took me almost 2 years to get started with the upgrade, mostly because I was not really urgent and secondly I needed a decent hoist taking the truck. A friend of mine is a mechanic and was planning to install a second hoist in his workshop big enough to take the truck. This eventually happened and since I am working towards our departure at the end of the year we […]

Lithium Starter Batteries

This is a catch-up post, not a very recent activity. It was a while back that I deep discharged my starter batteries again. Had not started the truck for a while and the lead batteries were flat again .. That was the signal for me to finally get the swap done to Lithium batteries. I am tired of lead batteries failing just because they were a bit discharged.

It is tight under the bonnet and my batteries have terminals on the side and not on the top because they would not fit anymore. The Lithiums are 40aH batteries and are […]

Long Time – No Post

It has been a while since the last post. The last 3 months I have been busy with other things, mainly the renovation of a rental apartment. This took eight weeks to finish. Done pretty much everything new … new kitchen, bathroom, floor throughout, new backyard (grass out, paving out and new paving in), plants, retic in front and back, new laundry, painting, couple new doors, new main door, new aircon, blinds, fence etc … painting of course inside and some outside.

I also have been busy with my commercial project and my truck.
