slick! Looks cleaner than the previous one. What DSP are you using? Is it configurable as per the ones from sigmastudio, with an graphical interface? (Not that I have any experience except for looking at YouTube)
Good luck with the finalization. I'll probably start fooling around with the jab versions in the meantime.

Hi
I’m still interested in testing this amp in a brand new boominator, any ideas when it might be ready? BJ

First modules should be ready in about 6 weeks. There is still quite some work to do on the configuration tool, but anybody who wants to purchase with fixed (known) DSP settings, like the Boominator, can send me a message. You will receive the module (4 channel amp with BT and DSP), programmer and cable harness for a total of 99€. Payment by bank transfer or PayPal. |

This is really impressing Lutkeveld!! Can't begin to imagine all the hours you must have put into this. Is the project still unnamed or have you found a suiting name? As it is only available with fixed settings at the moment, will it be possible to change from fixed settings in the future if I bought one now?

The project has a name:
ZOUDIO AIO4CH Here is one of the latest pictures with a plexiglass enclosure: And here are some previews of the configuration tool: And yes, the firmware will be update-able in the future. |

The first product is now online. It is a BMS for 3/4/5S lithium packs. For anyone that wants an easy way to protect and charge their DIY packs.
Features: -Under/overvoltage protection -Overcurrent(/shortcircuit) protection -Cell balancing -1A MPPT charging circuit for charging from a 24V PSU or even a solar panel (only for 3/4S) Link: https://www.tindie.com/products/zoudio/bms345-protection-and-charging-for-345s-lithium/ I will soon do a testrun of the amplifier at the same contract manufacturer |

Looks great and very useful. However, I have 100W solar panels (~18VDC (Voc) at ~ 5 Amps. Would connecting your circuit to this panel destroy the circuit? Maybe I should get multiple circuits, lol.

That should be possible, the MPPT point is 17.2V and maximum input voltage is 28V. The charging current is by default 1A, so it would just pull as much as it needs for that 1A charge current. You can not 'overload' it by giving it too much power. I can modify it to a maximum of 4A if that is needed.

That looks like a great solution for 12v rigs!
Pretty keen to buy one in the future (when I get back to box building)
