I went down last week and finished of the floor of the pool table room. Also added the wood framing around the metal posts and beams. The room just needs the false ceiling like the rest of the lower level of the house now.

I also was finished building the log trailer so it went down for the start of it's hard life dragging logs. The idea of this trailer is it can be dragged by the quads, buggys or a car, anything with a tow ball actually. You jack up the front of the log and it sits over the axle where it is strapped to the axle using a tie down strap. You can then drag the log without the front end of the log hitting everything hanging out of the ground. The other end of the log just drags on the ground. This has advantages. The end dragging has a braking effect so it doesn't push you down hills if you need to drag the log downhill. Because the majority of the log is off the ground it is much easier to drag. As the majority of the logs I'll be dragging are in amongst other trees, it will be quads doing most of the dragging. Most of these logs I want to move are taking at least 4 men to lift the whole log so that gives you some idea how heavy these logs can be and they need to be moved a couple of hundred meters.

As you can see, it's getting cold lately. It is hitting 0c regularly and the firewood pile is going down.

I haven't quite finished this farm project but it is near complete. It is exactly the same as this one I made in 2001 seen here except instead of being mains powered it will be solar powered....

What it does is charge batteries. It has a smart charger that charges batteries and once charged it drops the current to just a trickle charge so as to only keep the battery topped up and not destroy it by over charging the battery. This is the mains powered smart charger I'll be using after I removed it from it's original case...

As I said, I want this to be solar powered so the transformer seen here needs to go and be replaced with a 12vDC to 24vDC buck inverter as that is the voltage the charger uses to power it after the transformer and 12vDc is the battery power I use at the farm from the solar panels and batteries...

A solar powered smart charger isn't that hard to find for quad batteries, ride on mover batteries or car batteries but what makes this unit different is it can do up to seven batteries using the one smart charger or at least it will when I'm finished building it. As these smart batteries chargers are not cheap, what I want is one that steps on from one battery to the next up to seven and then starts over again at the first battery. That saves me needing to buy seven smart battery charges. The charger charges each battery for about 6 hours and then automatically steps to the next battery. This is the part I need to made, the stepper unit itself...

That is the drawing of the stepper board I designed. The art work of the PC board after I drew it onto the copper cad board and the etching powder I add water to so as to eat out the copper that isn't drawn in blue. What is blue will be the copper left that makes the tracks that conducts the power on the board. It will be a printed circuit board.
The board goes in the etching solution and after 15 minutes you can see the board slowly being made as the solution eats away at the un- covered copper on the board....

After there is no bear copper left, it comes out of the etching solution, is washed and I sand the board with wet, fine wet and dry sand paper and the board is ready for the components to be soldering in once all the holes are drilling in the board for the component legs etc.

This is the real old school way of making your own PC boards. They are not perfect because you litrallt draw it all freehand but it is better, much better than using pre drilled boards with tracks that you cut what you don't want. It is also handy when you want just one board or as a prototype to test if the idea in electronics actually does what you want before having a larger batch professionally made. I know this circuit works, it is exactly the same stepper unit that I made in 2001 and has never been turned off since in my garage at home I use for charging batteries on. I figured I would at most make two of these units to keep all the farm's machines batteries fully charged but I now have a few other people interested in buying some so I now need to have them made for me I guess. The stepper board can be used on any battery charger, it makes no difference. It is the stepper board that makes this idea appealing to people that have multiple batteries in vehicles they want to maintain the batteries in such as a collection of show cars that are garaged for long periods of time. The board is near complete with all the components soldered in but wasn't at the moment of writing this post. I will show the finished product here when it is finished. Hope some of you found this interesting. It is a hobby I have done for many years before it was all made ever so easy.
