I know since I've blown them up on the bench before. They explode like a firecracker. Nothing wakes you up quite like an exploding capacitor.
...You want your Zener to have a voltage spec a little lower than the cutoff voltage since the logic will toggle low a small amount above zero volts. A 6V Zener should get you close, but there's wiggle room in the logic levels so it can vary depending on the regulator. It also depends on the resistor value since higher values can cause offsets due to leakage currents. You want a higher value resistor to minimize power loss, but if it's too high, it can cause an offset level above logic low.
CapeCAD had used a 100K for the OKR-T3 and no one at that time had set up the OKR-T6 using the enable pin.
Remote On/Off Control (Note 5) [Standard version] Positive Logic ON = +1.5 V. to +Vin max. or open pin OFF = ā0.3 to +0.4 V. max. or ground pin Current 1 mARemote On/Off Control [āEā version] Positive Logic ON = +2 V. to +Vin max., 49Kohm pulldown to ground OFF = open pin or ā0.3 to +0.4 V. max. Current 1 mA max..
The On/Off Control is normally controlled by a switch or open collector or open drain resistor. But it may also be driven with external logic or by applying appropriate external voltages which are referenced to Input Common.
I've built two of these now and both are outputting 6-7.4 volts? I've checked thoroughly. My wiring is fine. What might be wrong? Thanx.
Thanx guys. No mamu I am gonna do that. I know what you meant but you also said make sure they're connected. The continuity test shows of they're connected. I know how to measure the resistance. I should have stated this isn't my first mod at all. Been modding for a few years. I also work on and modify my own guitar amps. So i know about testing it all. I just haven't yet. I just saw that one trace needs to be cut. That's going to be where my whole problem is I bet. I didn't cut the trace where the resistor is. Otherwise mine looks exactly like that one you posted breaktru. I'll try that today and I bet it fixes It all. It's allowing that resistor to be partially skipped. Makes sense now. I'll report back once I try.
I have a quick question that is probably super noob...When using a slide switch as power off, what are the specs on it if I am planning on pulling 10A?All the switches I have are <1A. Am I missing something?What slide switch should I use as an off switch?
If I were doing a build with the PB switch inline with power and pin 2, could I still use a Zener diode from pin 1-3? Or would that not work?I have not used sneer diodes before, but low voltage cutoff sounds like a good idea...
So a Zener would go from the switch (that is going in to pin 2) to pin 1? And with a 5k resistor from 1-3 to stop the okr from auto firing yes?
Hey guys. Been on EcF form a while then joined Mamu's forum and heard about this forum. I'm hardly on EcF anymore anyway. I own Mist Vapoe, LLC and I make custom wooden mods. I use DNA chips so this is a little dif. I get the caps before the switch but what resettable fuse would you use. I have a bunch on the way but all I have now is small fuses that will not reset. I don't care if I blow them but where is a good place to start as far as amps.
Hi JonGio and welcome to the forum. Nice of you to drop by.We've had some discussion about it in this topic as well as the "Wiring a PTC" topic.For the OKR-T/10 use a 10A. Two 5A fuses in parallel to half the PTC resistance and double the Amp rating.For the OKR-T/6 use Two 3A fuses in parallel.
Thanks a lot. Is the thread called wiring a ptc
