It is still missing a few important parts... power connector + labels, footprint for optional soft-start capacitor... If you should have an idea what else to put on there, let me know. Keep in mind that these modules should be 'dumb' and there will be another board which is supposed to control them (PWM dimming, maybe IR receiver or PIR sensor). The board is designed to run at 24V DC (or a bit less) and will draw about 100mA. Total light output should be 180lm. If the cooling via the copper pour is sufficient, I might increase the current a bit.

I have a couple of PT4115 LED drivers in the mail. This adapter will allow me to prototype on breadboard / perfboard without too much trouble as far as soldering is concerned.

If only I hadn't stirred! Oh, this is rice pudding btw. - at least that's what's printed on the container. The pre-stir pudding looked pretty good and it tasted pretty good too. The vanilla note was a bit on the low side, but it was OK. When I hit the bottom of the container, things started to go bad. I think this is what you get when 'aroma' is made by people who usually deal with plastic, polymers, additives and synthetic lubricants. Vanilla aroma made by Chem.-Giants. YUCK! And it doesn't even taste like Vanilla. There is a sickening smell of ultra-cheap baking aroma (pseudo-rum) or similar stuff. Next time just do it without the yellow CRAP and it will be edible. The sad thing is that today's youngsters will probably prefer this abomination over real Vanilla ("what's all this black dirt doing in there?").

This is what you have to deal with because mother nature didn't feel like giving you proper feet. Hearing grinding sounds coming from my knee doesn't make me a happy camper. We're NOT amused! --- Diagnosis (shortened): Bad news: 2nd to 3rd degree damage to the cartilage behind the kneecap + some sort of oedema + other minor stuff. Good news: No 'free particles' floating around and doing more damage.

and it smells too! Consistency is much like Nutella (chocolate spread), but I surely wouldn't want to eat that. At least I hope my knee will like it.

Yes, yes... But I like it nevertheless.

Now I can play with some of the INA high side current sensors. The solder pads on the bottom allow to jumper each pin to Vcc, GND or leave it floating - as needed. There's also room for two capacitors. It is really a shame that it takes 3 weeks for airmail to get to me from the US of A. I blame customs for that. I wonder why they don't employ more staff and speed things up. There must be a system behind that.

Hmmm... is this normal?

I will not send it back because of that. Shouldn't happen though.

I couldn't resist for long. At least I managed to dismiss the urge to shoot another of these 'unboxing' videos.
