I would like to convert PWC from my R/C recievers to linear for various sound cards.

I see Revo Electronics do a nice, compact board:

Looks very simple, anyone made their own?

It’s just a low pass filter. Easy to build, but that’s a pretty good price!

Here’s an article on the subject: https://www.allaboutcircuits.com/technical-articles/low-pass-filter-a-pwm-signal-into-an-analog-voltage/

not worth trying to build your own at that price. (https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-cool.gif)

A good article- thanks Eric!

Greg, I know what you mean. The shipping is the killer, double the price if you order 4.

Alec just a reminder these are just 1/2 amp. RLD did have some, not on his web page any more call him he may still have some or get some for you. they may be on sale because of DCing them

Richard

sorry

For sound cards with a “speed sensing” input, 1/2 amp is fine.

For decoders that don’t like pwm and you are powering the entire decoder, you need the larger one that handles 5 amps.
