I have many types of chips and a very long list,so if you need a digital chip ,like 4000 series or 7400 or may be op amps i have many to give for free
just list the chip you need and i may have it.have over 1000
I am doing this mostly because i dont need money and will help others with thier project and same money
Plus also free relays mostly reed relays
I have the same degree JDAWG ,i got mine over 20 years ago
MY question is very easy,i here some say the darlington transistors are better then mosfets for switching items off and on
AND on protection for flyback kickback on inductive load on the best place to place the diode on the coil or on the collector to emitter.
JUST wanted you opinion on it
ANSWER it in my post under switching circuit for digital outputs
switching circuit tutorials for digital ouputs
no thanks, i read part of that thread not getting in the middle of all of that. i think you know what my answer is though
OK THANKS and yes i do,its same as mine answer i just wanted another good second opinion from another engineer like me.
BACK to the parts for free,let me know what parts you need and most likely i will have them
Nobody disputed your comments about mosfets or the flyback diode, they were just briefly questioned and some of us disregarded them in favour of the typical TIP122 (for many reasons). All was added to the tutorial topic as options also. This is the very reason you frustrate me and I can no longer engage in discussion with you, you clearly do not understand posts correctly and get bent out of shape when anything is questioned or asked to be explained. Not posting to offend or even discuss, just attempting to explain why you cause so much frustration to many on these forums and others however fear that I can attempt to explain to you but cannot understand for you. No reply is necessary.
NOT GOING to argue anymore on this,but there was DISPUTES on my comment about mosfet and flyback diode
One reason no more posting ,so there will not be any argue ,you have your opinion that may be wrong or may be right and i have mine that may be right or may be wrong.
Pointless going back and forth arguing or trying to prove another person might be wrong.
I post my ideas that atleast i test them and they work to HELP others in building robots like me.
THis post is about me giving free parts to anyone who needs it ,so lets leave it as that.
