If it can be done he can do it, it would work with just the relay configuration as well.

I will be seeing him next week, i have sent him all the tech stuff on C5 circuits etc so will let you how it goes.

Is there a circuit for the relay only configuration any where that i can dowm load or get a copy of ??

I know theres not much to it ??

Hi PLOD11, that would be good, We maybe able to bounce some ideas.

Exciting stuff Plod - looking forward to the finished item and placing a large order  :) :) :) :)

It will have to be known as Plods pod !!!! ;D ;D

We are looking at something based around this chip or similar ..

John, you might want to look at the ATMEGA168 too :)

I spoke to the man who is going to make these boards,  the voltage side is not going to be a problem and will be a more reliable indication of volts condition of the batt than the POD is at present.

Current side is going to need a bit more work, i am going to take one of my C5s to him so he take the measurements with the motor on load and without etc ...

Was wondering if we could get by with out the current indication ?  But he will continue with it and hopefully have a prototype soon ..

Hi I have started to have a play and have ordered a dc current (Hall effect) transducer. This will work on 24v dc circuit and upto 80A and will give an output of either 0-5vdc or 0-10vdc. This in turn will then be sent to the pod left hand side and can be used to a circuit to use resistors to the 7 LEDS. This will give a true instantanious current drain / usage. That the theory anyway.

Re: My 1st C5 up and running - But now its a full restore and 24v conversion

Hi all, some photos of the restoration.

Chassis, hoop & forks - sandblasted, 2 coats of undercoat, 2 coats of paint, 2 coats of lacquer.
New fan to keep the motor cool.
New 18mm drive belt.
New Uni 8 controller.
New throttle and modified handlebars to suit.

Heres some photos..............

Being a biker I always fit the throttle on the right hand side, it's more natural  :) Plus it keeps the rotation correct.

The old c5alive 24v kit had the throttle on the left but this meant turning it the "wrong" way.

Hi all,

I have been having a play with monitoring the dc current. As previously advised I have bought a dc current transducer that gives out a dc voltage 0-10vdc in respect to 0-50A.

With a motor just connected with no resistance to its gear I get 1.7vdc from the transducer but but rapping the cable round its core twice it gives 3.2vdc. I tried using a rag to increase the resistance (simulating strain on the motor) which gave an increase in voltage to 4.7vdc from the transducer. If the motor runs a a max of 29A then I should be able to us a simple resister dropping circuit to light the leds on the POD.

I have however melted my gear so need a new one if any one has one for sale or if Chas can sell me a metal converted on.......

Some photos.

This sort of damage is why I haven't gone down the route of 24v, but when Karl's Dragon gearbox is ready and you can save your old gearbox from distruction then I would be more tempted, good luck in getting it sorted.

Hi Retro Andy,

The damage on the gear is not from the conversion it was me holding a cloth whilst testing to see what current (voltage change) to act as resistance. The heat from the cloth melted the plastic gear...... Sorry for any confusion........
