BC,
Very impressed.... :bow:
Not very often I see well executed projects...
What pcb cad program do you use to create your boards?

Thank you, kind Sir. Cheque's in the post ... :lol:
PCB is done with ExpressPCB. If you look up Eric's thread re: PCB Layout the download link is in there.
I like it. Nice and simple to use. Does for me. Easy to make custom components etc. IIRC I had a reasonable grasp of doing a basic PCB in about a couple of hours.
No doubt it isn't as professional as Eagle, but I don't need that level of performance. Nor is the free version limited to number of holes/PCB size ..
Have a bash at it. Costs nothing. If you don't like it, dump it. :thumbup:
I have never seriously tried to use Autorouters to develop a PCB from a schematic. Easy enough by hand .. for any stuff I'm likely to do anyway.
ZZZZZZ's time. Seen enough of today, or rather yesterday ...

Found the link for you. While having my Glen Morangie ... two hours overdue I might add .. :beer:

Tank you for that, so what wa the cost to get a board made by them and how long did it take I have a machine I would like to fit it to,or if you hve any spare boards you might want to sell I am ok with a soldering iron still .
thanks for posting al the information

I make my own PCB's .. sometimes successfully ... :ddb:
As a rough guess the h-bridge PCB cost some £15 - 20 for the laminate and components.
The processor PCB some £8 or so for the same.
Probably more expensive than a Chineeeeeese version, but this is fixable if ( when ) it goes pop ....
I doubt if it would suit another application. I was designed ( ??? ) around that Maxon geared motor. It is 36VDC but goes way too fast on that, so I run it at some 17VDC max, which puts it somewhere near right.
So, unless you have another motor the same or very similar, it won't work properly.
In fact, that set up will only be OK between some 8-18VDC. otherwise the 5VDC to the pic will be at risk below 8VDC ( 7805 input dropout ) and the TC44xx are 22VDC absolute max ( IIRC )

Ok thanks for that would this motor do ?

they are a good powerfull motor the advert says they are 12 volt but when you look them up it says 24v we all runthem on 24v. I have fitte plenty in big boats and at 15 to 24 volt they are fine get a bit warm with a big prop after a few hours so short bursts you should even be able to take them up a bit
