I've seen a vid where a guy was doing this to free broken studs from an alloy block, just can't find the link at the mo sorry. https://en.wikipedia.org/wiki/Acetic_acid#Reactions_with_inorganic_compounds 1 Quote Share this post Link to post Share on other sites
peteretep 5,329 Report post Posted August 18, 2019 hey guys I have a couple of 2 wire DC motors I want to get plugs for, so they can be removed easily. I have tried bullet connectors but they just arent up to the task, and this isnt being fitted into a car so not really suitable. Whats the next step up in plugs, something screw together? Its for 24V 15A Quote Share this post Link to post Share on other sites

Ghostchips 5,061 Report post Posted August 23, 2019 Do you have tons of old cellphones or some supercap/ultracap's around? Could make a voltage stabilizer thing. I have a few shitty zener diodes but i don't like that method. Quote Share this post Link to post Share on other sites

Snorkpipe 295 Report post Posted August 25, 2019 Does anyone know how I could convert a piezo-electric signal into somethin a control unit would see as either high or low input? The pieze has around 1V AC, and the control unit wants either 12V DC, or ground as it's input? I have tried using a transistor to pull the control unit to ground, but that was unsuccessful Quote Share this post Link to post Share on other sites

Yowzer 26,943 Report post Posted August 26, 2019 Sure about that? A multimeter won't necessarily tell you if it's dropped a winding and will still read 13-14v, but the AC fluctuations can mess with switchmode supplies like the powerpack for the camera Turning on the headlights will drop the peak voltage, leveling it out with the battery float voltage and stop the powerpack freaking out as much. A capacitor will only mask the issue. Quote Share this post Link to post Share on other sites
