Hellow,
I want to built a bedini motor, and for the reedswith and pulses i want to use a pic+eeprom micro controller.
The one i want to use can swith at 2000/seconde
Is that quick enough to swith to capture the 120V spikes? ???
Thanks in advance
Thomas
The specifi on the micropocessor is:
24 digital I/O-lines, 8 of them can be defined as analog input (8 bits resolution).
1 counter-input, can generate an interrupt when the counter goes from 255 to 0.
2 I2C expansion buses for real-time clock module, LCD module, additional I/O-lines, A/D, D/A, EEPROM etc.
full duplex RS232 serial communication at 300 / 600 / 1200 / 2400 / 4800 / 9600 or 19200 bps.
RS232 receive buffer: 32 bytes
the counter, rs232, expansion bus and I2C-bus do not use the 24 standard I/O-lines.
reads the unique ID of Dallas iButtons.
260 bytes of RAM
types of variables: words, bytes, booleans, array of byte.
processing speed max. 5950 Pascal-instructions / second.
based on the Microchip PIC16C77 (PDIP-40).
operating supply voltage: 2.5 V to 6.0 V
Lol,
Do you want to build a Bedini or play with microcontroller ?
(Your title are not exact you havnt got a microprocessor, juste a microcontroler (witch is not the same) )
So, why don't you build a basic setup like that or other

After you can improve it or build a wnidow moto coil, or SSG2 with a mecanique sensor and after you can put you electronique sensor and you µC, and what you want....
Be simple, first valid the concept and AFTER improve it, it's my opinion
Or if you just want to play with µC there are perhaps more interesting to do with....
Sorry for my bad english
Have nice day

thanks for your reply,
I realy want to use a microCONTROLLER(btw the pic is a microproccessor) to control the pulse and to switch.
Mechanics are not my first degree, so i rather start of with the program and microcontroller.
I know that you first have to give a pulse, then before the currents starts you can collect the back emf??right?? ???
I just want to know how fast the microcontroller has to switch in order to get the switch and pulse right.
so 5700 pascal lines per second, wouldt that be quick enough?
ps. i understand that if i first 'play' with the bedini girl i get more educated, and i also will do that, but i really like a microcontroller in the proces of doing that, so i can precisely regulate the system and adjust it properly
Thanks 8)
Hi,
I rigged up my little window motor to a PIC16F628 only a couple of weeks back. It was much harder than I thought to get it running.
I used the trigger winding to turn on an off a 2n2222a which was taken to +5v with a 10k resistor. The collector then went to the PIC micro. When the collector was low the transistor was on and the PIC turned on another output which fired the motor stator coils.
Then you can ensure the ON time for the stator is as long or as short as you like. However if too short the program saw the input low by transformer action between the coils and the program ended up looping. Also it means you have a set RPM, unless you can write a very dynamic program which allows for acceleration. I gave up, Johns original circuit its much simpler and MUCH BETTER!

Thnx CTG Labs!!
I think i know enough for know, to start building!
i let you know when i first reach overuni ;)
thx Thomas ;)

I think that the point of the Bedini SG is that it is self triggering. You are trying to solve a problem
that doesn't exist. Build the SG exactly to specification, and then modify it if you must.

Hi Paul, thanks for your reply.
i just don't want a transistor that warms up in my circuit!!
i'll switcxh everything by programming and cencor inputs and i've seen a cool compas-module ;)
Found a great module that w'll work fine:
~6,000 instructions/sec
@ 5V 5 mA Run / 150µA Sleep

next step without the bedini motor, first i'm waiting for my Module.
Thanks anyway!!
Hi,
I think the point is that the "radiant event" accompanies the fast spike, that is why the circuit is done this way. You will still need a transistor to drive the thing but a microcontroller is not going to be able to create these spikes. Remember, there is nothing magic in the motor, its just the spike and the battery!

whell i need the chip anyway to get some info on my display when i'm driving.
I think i must tell you i am building a van with batteries and a generator to charge the batteries.
Does someone know if this accupack will radiant charge?
