A Road Rage Tinkered Up "More Safely"
« on: May 02, 2021, 01:19:22 AM »
Hello there,

Here's my idea for wiring up a Road Rage.  My idea is to wire up to a 2-pole 6-position rotary in combination with a 3PDT (on-off-on) toggle that will both prevent incorrect electrical polarity, and indicate which polarity can be selected by the rotary.

Obviously, this isn't to be "more safe" for a human, but for the pedals I'm wiring up.  The idea is to wire up the Road Rage in such a way that will force me to be more careful when wiring pedals. Rather than just relying on a single rotary switch to select voltages, the associated toggle would separate + voltage from - voltage (and indicate such), thereby preventing me (or anyone else using it) from casually sending +18 into a circuit designed for -9.  The idea is that circuit would not work if the rotary were selected to "+18", but the toggle was on "- voltage" and vice versa.

The attached diagram is my first conceptual attempt of how this would work.

Also please assume that the individually drawn Red/Green LEDs are actually a single R/G LED.  The red dotted line through the rotary is the axis that splits the poles and their corresponding throws or positions.

The left side shows the labelled rotary and toggle as they would be seen working together from the outside of the box.

The reason I'm not using the DC Out ground lug on the Road Rage is because I plan on combining this with a JMKPCBs Testing Rig that would be wired to those lugs


Sanity check: Is my idea here overly complicated and unnecessary?


Thanks!

I like the idea, but the inherent flaw is still you, or the operator. You still have to remember to turn the rotary before you plug in the pedal and not after.  :P
Pedal building is like the opposite of sex.  All the fun stuff happens before you get in the box.

I had this more or less built into a previous testing rig (rotary switch selecting different voltage outputs). It is quite handy.

True.  The additional toggle switch and indicator is supposed to be that extra reminder.

Thanks!

I appreciate the vote of confidence.  I was originally going to use the 5-outputs in the Road Rage documentation. After seeing other testing rigs and mulling over your rotary diagram in the Road Rage documentation, I was inspired to take it to the next level (and not have so many power outputs!)

Thanks!
