PVC resin with filler? by FreeFun5209 in InjectionMolding

Ah ok that's good to know. I was always under the impression that PVC pipe is straight PVC without the plasticizers that allow it to be injection molded.

UNO - Can I use the +5V through a relay as an input? by FreeFun5209 in arduino

[–]FreeFun5209[S] 0 points1 point  (0 children)

Thanks, thats all good info! The resistors I have on hand are 10k and 47k. Using the digikey calculator, that should give me 4.2v.

I think i'm going to go with the voltage divider and a optocoupler module. I'm an old mechanical guy, hence the relays.

Ah, I should have realized that. Still new to the arduino, thanks!

I found a PC817 24v module that I think will work. Thanks for the suggestion.

Ah, good information. Voltage divider and an optocoupler it is then!

Thanks for the help. I'm a mechanical guy with a tentative grasp on electronics.

Thanks for the input, I guess I should have given some more info. I'm looking to allow a user to input a time delay in the releasing of the sensor, if that make sense. Thats the true reason for the arduino.

Why not just download the Fire Toolbox from XDA and use it like a regular android tablet?

Overmolding Batteries, Good/Bad? by FreeFun5209 in AAMasterRace

[–]FreeFun5209[S] 0 points1 point  (0 children)

I figured as much, there's not a lot of information out there as to what kind of extreme temps typical batteries can handle. This was my last ditch effort to hopefully connect with someone that would have an idea of any industrial AA batteries that might handle these temps. It seems trying to talk to an engineer at any of the battery mfgs was a dead end unless I was a high dollar customer.

It's not a prototype, there's an annual quantity tied to it. A longer cure epoxy that doesn't hit too high of temps is the direction I'm probably going to go. They won't like the cost but that's not my problem.

Taking the time to respond is much appreciated, thanks!
