Hall affect to potentiometer

[W4yneo]

Hi there.

I wonder if anyone one here can help.
Is there anyway I can wire the common hall affect type throttle to a a potentiometer, or should I say replace a pot with a hall affect throttle?
Or does anybody know where I can buy a resistive / potentiometer type throttle?
I have found the expensive type ones, but didn't really want to biy an expensive one at first.
Regards

A few things:

--Yes you should be able to go from hall to pot.

--The bitterness of poor quality remains long after the sweetness of low price is forgotten.

--Go Domino or go home.

--Get a Cycle Analyst v3 to calibrate the output range and do all the other ebiking must-haves.

--A cheap throttle will insult you every time you twist it. Yes, there is that big of a difference between throttles. It's only your interface to controlling the entire bike the entire time you're riding it...

Domino and Magura make potentiometer throttles. There are also "Pot Box" units that use a standard cable pull motorcycle throttle. Using a hall throttle with a controller made for a pot depends on the controller. Something like an Alltrax made for a golf cart might be pretty challenging to use with a hall throttle.

Here's a nice pot box setup:

Thanks guys
The motor controller I have has a pot installed, I wanted to desolder the pot and use a throttle, hence why I didn't want to pay for an expensive throttle, just in case it didn't work. The pot fitted to the controller is an 100k, are the throttles only 10k?

I've seen 5k throttles too, but not 100k. But a 10k might work if it's being used in a divider circuit. If you measure the voltage on the throttle pins while moving it, you can get an idea.

If you get a cycle analyst you can run the throttle thru that and just program the throttle output range, with all the other power consumption and bike computer functions as a bonus.

If don't mind buildng it from scratch, Maxim makes Digipot chips that convert a voltage to a resistance. They're simple enough to use based on their spec sheet circuit diagram examples. Go to the Maxim electronics website and look for Digipot and you'll find them and the appnotes on them.

Thank you very much guys, it is appreciated
