Some people asked me explanation about "Volvo" so I decided to make a new-one and take some (bad) pictures of it on it's way to life....
I took special attention that the gears and motor are easy to find (and cheap too).
as usual I don't bother making Electronic research and took a look at my friend Math Vos homepage http://home.wanadoo.nl/m.m.avos/ to got an exciting circuit (based on his "ALI" this time).
I won't give you specifics mesures as you're free to find differents
parts....Just contact me if you really want.
First you need some tools :
The main frame is based and two side panels holding the complet transmission joined together by a central piece which hold batteries and electronic.
How to make the sides :
Start by a 3mm hole, screw the firsts gears (the one on motor side.
Mark location of the second
set of gears and drill.Screw it back not too tight and be sure rotation
is smooth, if not enlarge the boring (a little !)
Be courageous and made a test
! try to avoid vibration and chainsaw-like noise ! (the screws need to
be tight so the gears don't shake but are free on rotation).
Cut the middle part the same lengh as sides one and cut gears location.
How to glue !
Put back gears, axles...
you can now adjust the motors position before gluing it (whith Loctite)Pay
attention of leaving some freedom between both gears (grind the gear or
stack some paper under the motor).
