.....Actually 20 secondaries rectified powering 20 regs with 20 diodes on the reg + powering 20 cells in series I was close though - just missed out on some small details, haha :) Yea I think id compare the supercaps to the batteries first, its simpler to implement youll have to current limit the r...

Looking for feedback on some different PSes I have produced & thought a local tour might be of interest & useful? All devices use direct power i.e. no regulators on the output as this provides best power delivery characteristics & best sound when used in audio devices. There are 3 variat...

.............. THE BIG QUESTION remains: do I simply wire up two assemblies - a 26650 with a 3.3 volts regulator/charger along with a supercaps at approximately approx. 1.9 volts regulator/charger and then put them in series? This is where I get concerned. I do not see a DC-DC converter at less tha...

Hi Rick Here are some suggestions: You can individually charge two batteries in series by using a normal vreg to charge the battery on the ground end of the series & using an isolated DC-DC converter on the other battery in the series - the isolation avoids the input ground of the DC-DC converte...

The Demo here http://apls.bliptunes.com/demo.html shows some more functionality - playlist & Jukebox Best to start simple & work up to building something more sophisticated once we have a simple working method The first link I gave seems to answer what we originally wanted - an ability to us...

I think we can use this player as the front end UI music player https://one.8ue.nl/# - looks really good (looks like an old turntable) & can run on phone Open the playlist (top left button) & drag music files to it to play a file The code is here http://apls.bliptunes.com/ so we can change w...

John Take a look at this https://flashair-developers.com/en/documents/api/lua/guide/#method2 Looks pretty simple to start a lua script on a "write event" Can also start one from a http request, but I write event sounds like what we want. I'm not really sure what a "write event" ...

I was thinking some more about this yesterday, during my evening walk. Here’s my proposal. The Flashair card support Lua scripts, and I have a tiny bit of experience with Lua. Write a lua script to run at the end of a file transfer, that sends a command to the ESP to start playing a new song. I did...

Randy, You should try Amplitudejs (yes, I'm back considering this as the best solution to our needs) https://521dimensions.com/open-source/amplitudejs It's a music player app that is a simple front end for HTML5 which means it will run on any platform. Its Java source is simple enough even for me wi...

Yea, I was thinking of the last option I suggested - transferring the file selected for playing to the SDP I can't remember the timing now but I was impressed by the transfer speed over Flashair & it may not be a problem in practice if one file at a time is being selected & played but if a p...
