9xr haptic mod

Postby viperman3 » 12 Jul 2013, 18:27

Has anyone tried to get the haptic mod done on their 9XR?
Can't find any DIY on this mod.

Though I'd reply to my own post. Just completed the Haptic mod on the 9XR and all is working good.

Shouldn't the transistor being shown in your picture be an NPN instead of a PNP? I'm using a 2N3904 NPN and it works perfectly.

Good catch, I agree it should be a NPN.
FYI, shorter wires around rf and in general much better. Wires in general act as antennas and may pickup unwanted noise.

Hello

Which type of vibration motor you used?
Where can I buy one?

I use cellphone vibration motors some call pancake motors. I buy them locally from a surplus store but others find them on eBay. They will work OK on 4.5v max.
Another easy source is one from a $5 electric toothbrush, the one with it in the handle.
You will need to drop the voltage to 1.5v to power it. You'll also want to use a transistor or BS170 FET to switch it on with.
The schematics are for a 5v motor. Use a 3.3v regulator for the $5 toothbrush motor and add some resistance to the circuit to limit the current to get the vibration you want. Too high a voltage will spin the motor too fast and not shake as good, slower is better.
I use a separate regulator so I don't load the main board regulators down if too much current is drawn. I don't want to risk a reboot of the radio or worse.
The motors can draw more that the radios circuits do.

Some circuit ideas

Already done the haptic mod on my 9XR using cellphone vibration motor and works great :). I will order a spare mainboard as backup, because after doing telemetry and haptic mod, I have damaged the pins of the processor so badly that another mission in there would be impossible :lol:

Did you find a spare board for the 9xr
