I have a healthy stock of IRF44Z parts so I suspect it may have been that - but the number isn't critical most power mosfets should work. I don't know the part number of the mosfet but the specifications a Voltage source to drain 60, Resistance in the "on" state is .04 ohms, maximum current 30 amps, TO220 package. No heatsink is required with up to about 15 amps or more. The entire circuit was mounted on 1" X 1" piece of perf board. All resistors 1/4 watt. I put the circuit in a small empty dental floss container and filled it with epoxy, running the wires out to a pair of 1/4" male "quick connects," that plug into the turn signal flasher connector. The on time and off time can be adjusted independently by changing the value of the 220K charging resistor (off) or 100K discharge resistor (on), or changing the value of the capacitor (both off and on). -- ----== Posted via Newsfeeds.Com - Unlimited-Unrestricted-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |
