RFI shielding for Stamp BS2
Archiver
Posts: 46,084
I need a simple way to shield a small (2 inch by 2.25 inch circuit
board) containing a BS2 and an ADC. This circuit is used to take and
save temperature measurements from my son's 1/8 scale gas powered off-
road racing buggy's engine.
We used this setup for taking measurements during the static engine
break-in process and obtained several very useful temperature graphs.
We now need to mount the circuit board onto the car to continue the
break-in/engine tune-up process. When we did this, we introduced
noise into the radio receiver on the car, causing some unwanted
actions of the throttle and steering servos.
How can I shield the Stamp so that this radiation does not interfere
with the radio receiver. Is there something I can enclose the
circuit board in to absorb this?
Thanks for any ideas and help.
PS. As a newbie to this board (been reading and following this board

How about a small tin, like an Altoids mint or similar?

of the time these clocked circuits generate RFI via the I/O
connections. I would suggest adding a ferrite bead or other RF
shorting gadget to anything leading to the outside world. Also
remember, RF has a way of being "detected" from any sort of
imperfect connection (read - paint or corrusion), so I would solder
a little piece of copper braid between the lid and base of the
Altoid box. Don't plan on a zero-ohm connection through the paint.
Then you've got a really cool (and inexpensive) Faraday shield.
