Re: [18650] rechargeable battery + super capacitor

Being as you are using a MC (the Raspberry Pi Zero), you can either include a battery voltage monitor routine that automatically puts the MC into low power / sleep mode, or a button push that would do the same. Once that is done, you can use a smaller capacitor since the drain will be greatly reduce...

Gain block question

Here I go again, another wierd discrete component audio query. Still in the audio reproduction mode (it's my main electronic interest ;) ) and this time I'm trying to understand how the "volume control" on the PSAudio amps work. Paul (the P in PSAudio) says that they use gain blocks for their volume...

Re: ok,, New Project time,,,

Don't forget what I said earlier about the top 22% being basically disregarded. If you step back and think about it, the original dial / readout registered full at that point also. So no matter what, you still have the same resolution and accuracy of the original setup. If it was good enough for the...

Re: ok,, New Project time,,,

If, initially, you don't get good results with a direct read off the sensor, add a buffer amp to provide more current or even a higher voltage range. That's about the only caveat I can see with such a circuit, since it usually sees a much higher voltage range.

We'll be waiting on results. Good luck!

Re: Soldering iron tip woes

You'll probably laugh and most likely wince, but on my OOOOLLLLLDDDD Radio Shack iron with the Pyramid tip, all I do is use a file to keep the shape and it retakes a tinning right away. Of course, I don't use mine as hard as you guys do, so I still have my original tip. :D

Re: Technology Backfire?

..... Maybe parking pointing North, so it can recharge from the earth's magnetic field will work. Only time, and the lemon laws will tell! Better check your local magnetic inclination! LOL Shouldn't you hang the car from a cable and let it swing across the earth's magnetic fields? Hmmm... :D :D :D

Re: Ham License

Hey jwax, missed the part about the USAF. Thank you for your service. To all who have been in the Armed Forces, a huge thank you for your service. Do either of you, or anyone else, know what's required for QRP / flea power? It's been years since I've read about it and quite frankly, can't remember w...

Re: Ham License

What is amazing is that I see quite a few amateur radio license plates in my little neck of the woods, SE Pennsylvania. I also think I see them playing fox and the hound quite often too. I have yet to catch a local hamfest or meet. Next local one is July 13. Hope to get closer to re-entering the lis...

I see these donuts all the time in the store. So tiny. Must be over a thousand in a box! And the name is so upbeat - it even has "Cheer" in it!
