    Help with slowing down and reducing the noise on a shaded pole 230VAC fan motor

    Firstly, you are playing with fire if you use this fan in an open environment. It is only single insulated and no earthing into the bargain. Shaded pole motor is also a synchronous motor meaning it's speed is dependant on mains frequency. Would be more sense to use a low voltage fan and a plug...

    High Side switching N mosfet

    Will this be self discharge as it is an insulated gate having it's own capacitive charge when on?

    Li-Po Battery protection circuitry placement

    I would tend to leave as it is, however, it may not be a protection circuit as you believe. May be just a termination board.

    High Side switching N mosfet

    Just finished going through a series of 6 videos on you tube from Julian Ilett in relation to using both P and N type mosfets in high side switching. Thought they may be of interest to some as it was to me. Starts here.........

    Help identifying component

    Likely you may have damaged something else as well. Shorting out a component sounds like a fairly broad statement that could mean anything. Get an electrician to check. They will have the knowledge and meters to check your installation. Last thing you want is to liven up the van chassis and...

    Sensor circuit

    Yes......it's not the idea that will not work but your mechanical setup. If the hall was mounted at the end of a brass tube and the magnet was mounted the end of a bolt for inertia the magnet would always approach the hall in the correct alignment. If you want the magnet to arrive higgeldy...

    Clamp on analog meter

    Looks to me like only half of the meter is there. Selector plate, springs balls all missing. Looks like the board coped some overheating as well. Not really worth even thinking about. Especially when an el-cheapo one can be had for maybe $30 on Ebay.

    Heat shrink as water insulator

    Raychem or similar as Hevans says WILL be both waterproof AND flexible. Used it many times in underwater application on cathodic protection. Samples of our idea once won an international engineering award .....trouble was the bloke who won it , stole our idea..... :) Even had the hide to use the...

    Bicycle generator

    Maybe use a car battery 40Ah and one (or more) of the dynamos that run on the wheel rim with a couple of bridge rectifiers. I doubt that 15 minutes of pedalling that will do any damage.:D (Could pass out from the hydrogen fumes if the Op was super fit.)

    Wanted: L265 Raytheon (Ray Marine) power cable.

    Not much chance (old gear) unless you can pickup something on Ebay but it would probably be nearly out of service anyhow . (being a waterproof plug that has more than likely lost it's waterproof capability) Might be a better approach to "hard wire the lead " with a circular cable through a...

    Wiring 5v to a 12v powersupply

    Use a 5v 1A plug pack or similar. Connecting to the 12v unit will result in smoke and ash.

    Maybe worth a try giving that contact plate and the mating socket in the vehicle a good clean and squirt with crc.
