The 220 ohm resistors are probably not the issue. The standard BOE has
caps on the supply that prevent servo surging from resetting the Stamp;
they are not on the Homework board (as there are no servo connectors).
Put a 1000 uF or larger cap between Vdd and Vss and I think you'll
probably see the problem go away.

Subject: [noparse][[/noparse]basicstamps] CMU cam and 7.5 Kgxcm servos don't work with
HomeWork Boards
Stampers:
I tried to use a
CMU cam and 7.5 Kgxcm servos with the HomeWork
Board
(item 28158) and they don't work.
Then I used and standard Basic Stamp 2 (item
BS2-IC)
whit BASIC Stamp 2 Carrier Board (item 27120) and
all
worked fine.
Even I used a second HomeWork Board but I have
the same problems.
I know that HomeWork Board has 220 resistors
but is this the problem?
Any help is welcome.
Thanks: Joe
