changing from analog to pwm

changing a relay box from analog to pwm

I noticed there are jumpers in the relay box for this, is there anything else involved other than moving them? I think i'm looking at the wrong version of the schematic because i dont even see the jumpers on it.

On this new batch of boxes you can.

[symon_say]

So if i order an additional relay box it will be able to deliver pwm or analog??

They are pre-set on manufacturing and welded shut.
If you break the weld, you would have access to the internal components.

interesting, I haven't been here for a while..
and I just have a PWM box, but need an analog for my new DIY LED drivers.
and I have a broken weld on my relay box do to some earlier this year little error with polarity....
do you mind sending me your schematic (ab08hun@gmail.com), so I can have a closer look into this my box

I uploaded the eagle file to the website, but you must have rev 8.1 of the relay box, which is pretty new.

I got the kit back in Jan-Feb 2012? with previous +/- polarity so we had to brake the seal. I would look inside the box but its mounted on tight sidewall and tons of cables to disconnect. Wondering you spare me the effort......

[rimai]

Definitely not.
The newer boxes were made within the last month or so.

not really welded, more superglued shut, pretty easy to pop open.

[rimai]

it's an ABS weld cement. I leave it lightly welded, just in case someone wants to pop it open
It I made a full seal, it would never be able to open and that's not the intention here...
Being an open source, I do want those few that are curious or want to tinker to go check things out inside

We do ultrasonic welding of plastic at work, just a chisel a vice and a smack of the hammer and you can pop anything open pretty cleanly.
