Re: Total Newbie Project- Sea Kayak Propulsion

I put a 12volt trolling motor on my inflatable kayak. Used a marine lead acid battery but was gonna upgrade to lion It went about 6mph You will need to make sure everything is in watertight containers and waterproof connectors as short circuit by water is always possible.

Re: Hardware temperature control tsdz2

Hi! I put the thermometer probe in the cavity behind the plastic cover and added some thermo pad to keep the pressure agains the housing. Not directly on the stator, but better than nothing (I hope).

It’s in the pic if u zoom in.
There are different thicknesses available. I bought one which was easy to bend.

Re: Hardware temperature control tsdz2

Found these at the Dollar Store
Not sure about actual copper content , but you could use a few to fill the air chambers.

Crafting copper

I found this was better than the copper tape
Only $7. Can cut it with sharp scissors.
Easy to bend.

Results of my heat reduction attempt using copper. It appears to be working well. I haven’t overheated yet on my long hill , but it’s winter and outside temp is 50 F here.

Re: Hardware temperature control tsdz2

Re: Hardware temperature control tsdz2

My idea for copper sandwich. Copper mesh between 2 pieces of copper tape.
Will use thermal grease and high temperature (500F) bearing grease which is much cheaper , at the contact points of the case to reduce air gap.

The temperature sensor and the throttle both use the same analog input on the microcontroller.
