Vlog style post: I've been designing a new PCB for the PWM5 solar charge controller which I'm calling the 'gumstick' version. This is an interim version - mostly surface mount - until I can source the last few components in surface mount version.

Hi julian, I am really interested on your project. You shared the PCB schematic for the Gumstick but I am interested to make the one using standard components and no SMD. Are you able to share the PCB of the standard version one? Thanks
This looks a bit hellish to assemble. You're not a vacuum pick and place machine, you need to be able to stick your tweezers in between things.
You really have to install a good screen capture program! Like Hypercam, for example, which is free. This way you won't have to print anything (and waste paper and ink, increasing atmosphere contamination).
A logic level mosfet would probably work better and eliminate the parts associated with the charge pump
My question is the firmware, your site doesn't seem to be live anymore for us builders to find.
Hi Julian,
would it be possible to buy one of your original PWM5 circuit board, with the through hole, I can pay via paypal, I have most of the components already. Please let me know.

Not sure if you have done it in a previous video, but could you explain how your high side driver works on the PWM5 and why you are using one of your own design rather than a dedicated MOSFET driver? Cheers.
You could cut legs of voltage regulator and solder it to surface. İ saw it in a pcb which i ordered from china.
Nice! Thanks Julian. If you drill the connector holes, you can add mechanical strength. Plain pads will be prone to the copper lifting, especially if your connector leads are heavy gauge.
Julian, are you planning make a video of assembly language for microcontroller for this project – I mean beinners style, like your videos a year ago, that would be great.
Have u got a MPPT design?
