Re: New Neural 'Brain' Controller

I'll say this again.
A Neuron is a function.
Axium = N(all synapses)
So for any input you will get an output. Garbage in garbage out.

Re: New Neural 'Brain' Controller

It is not new. A lot of this was done in the 80's and 90's. I wrote a book about hardware to do this in 1996. I have another book not published yet called "Neurons for Robots" I have posted a lot about that in this forum. The reason real neurons don't work is because they are alive and out of their ...

Re: Shamefull personal commerce

MrAl
Kindle and Amazon are two different sources.
The book is about elementary math from a long time poster here.
Book 1
What is first?
Book 2
Numbers and number wheels
Book 3
The computing machine as a math object
Book 4
Hal Algebra
Book 5
Hal Trees

Is that sufficient?

I use pic 12F629 and 12F675 as nodes in Hal Trees.

I think with what you have, I would just hook up the pattern you want
directly to the PIC. It will turn them into ones and zeros to give you an
8 bit word.

In that same time period, Toyota made an EV conversion of their
RAV4 and sold a few. Most off them are still running today.
EV1 got Nimh batteries before they got into production. But they still went into production with lead acid batteries. I think electric cars scare
gas people.

If you can find one, read "The Car That Could" by Michael Shnayerson
Random House 1996. I got mine at Amazon as a used book.
Its the story of how the EV1 got to production. Not how it was killed.

Use some real numbers here. I just swapped an 18 hp gas tractor for a 33 year old electric tractor. The gas tractor had to have a new engine. It was two years old. The electric tractor uses 6 lead acid batteries. It runs longer than I can tolerate mowing. Instead of 18 hp it uses less than 1 hp. (36...

Replies: 5

h-bridges have only two inputs, direction and go. So you can drive them from almost any pic. Direction is dc, that is held forward or backward.
So you only need one pulse control. Full on is DC on full. Half speed is pulse is on 50% of the time. And so on.
