Wow thanks for that, think I may have an alternative solution never spotted your reply till just sorry...
I have a LM3524 that is giving me a variable pwm of 10KHz on output pin 13, basic circuit is attached as my schematic software is no longer functional I am having to resort to alternative...
I have no idea how fast it is running, we tried to clock it and found it running at 5,600rpm..
Most of the lures machine's run at roughly 43Mph, length of braid plus weight of dummy bunny and the obstacles it needs to run round to simulate a rabbit running, I believe we need max power and...
Thanks for that, I am thinking of using a LM3524 in line with a mosfet driver in a half bridge configuration... but then I just spotted your additions to the thread... some more food for thought...
The 6v battery is a novel idea...
I did initially think 12v dc coil and contactor for switching...
Hence the reason I am asking for help, just never used a Mosfet before...
How would you control the speed, the option on Ebay is very expensive with Delivery charges etc...
The only high current switching I have ever done is with Big Contactors and coils, but never electronically
Most I have...
As I have never done any projects before involving a MOSFET, do I treat it the same as I would a transistor?
would I also incorporate overload and short circuit protection around it, or just use a fuse?
Also would I be safer to use more than one MOSFET with the source and drain connected together?
So I have been having a think about this, would I be ok using a NE555 to produce a variable PWM output that is then connected to the gate of a MOSFET possibly via a NPN transistor to prevent accidently switching on of the MOSFET...
Would this work, I have got some basic hand drawn sketches but...
Hi SunnySkyguy,
I'd love to see your outline and get the brain cells working again, as it's been a while but I still have all the necessary equipment here and pcb etching equipment etc...
It's a side of things I miss, so would love to get back to basics and start from scratch and design and...
Hi all,
I hope this is in the correct section if not could a moderator please move it to the correct section...
Basically I have a small project I am working on, but it's been a few years and I am a bit rusty on my basic principles etc
I have built and have running a lure machine, for...
