Not the prettiest of heaters but I did make it. Only issue is I keep blowing mosfets but I believe it's because they are really low Z4A and not irf250's but that's what I have on hand. Thanks for the instructable :)
Hello, i'm having an issue with my mosfets. I have a bunch of IRF650b mosfets that seem to all be staying open. I test them completely and they wont discharge and close. I am testing them with 5 and 12v. When I test my FQA9N90C Mosfets, They work just fine. Is ther something different about the 650's that need to discharge or are they all no good? Thanks for any help.
I know this is late but maybe because the colour code is actually br-bl-bl-gold for 10 ohms. the colour code or-br-bl-gold is 31 ohms, going by calculator and is a non standard e24 series.. Hope this helps
