Hey there!This is a nice little project and I really appreciate the effort you put in. At the same time I wish, that you would explain the principles behind your work. Like your other instructions it is more a "how to connect all parts", which is great if someone just wants to replicate. But you could teach the people so much better if you would explain how and why you did the things. Help others to become as smart as you are! (maybe you know the phrase "give someone a fish and he has food for one day - show him how to fishing and he will have food forever")Otherwise great work!

Thanks for your nice words and you trust in my skills! To be honest, I never made any researches on how to solder smd. So from your video it looks like:a) put some solder pasteb) place componentsc) put it in the over (for some time at some temperature ^^)d) solder the other parts the "conventional way"Is it really that easy? What time and temperature do you recommend? Regarding convection: couldn't you build a metal fan and add it to your oven by yourself? DIY-style ^^From tool side I have a upper-medium class soldering iron from Ersa. I could need a good regulated one, but mine has a good temperature for pcb soldering and I have several exchangeable tips. But if it will break one day (already several years old and still good) or I can give it to my kids. I also have a cheap l...

I could need a good regulated one, but mine has a good temperature for pcb soldering and I have several exchangeable tips. But if it will break one day (already several years old and still good) or I can give it to my kids. I also have a cheap logic analyser and an atmel debugger which is super helpful. I still miss an digital oscilloscope. You have a Rigol, right? DS1104Z, right? It looks like one. How much was it? 600USD? Quite some money... But I really need something similar sooner or later :-) time to save some money ^^But first I will check to get into smd soldering. One last question: where do you order your pcb? I know pcbway.com, they are quite cheap (5€ for 10 pc of 100x100mm) but have some shipping costs (up to 5 times pcb costs) to Germany.

Dude, this is awesome.First I thought "Hey, cool headline, let's check". Then I saw the beginning of the video and I was "oh, he just assembles something he bought" and in the I was "wow, he created everything, designed the pbc and the body and let it been manufactured on an industry quality". Super awesome! Most of the time you see bread boards or prototype pcb here. This would obviously not work in such a small scale. Sadly I can't solder smd. I don't have the tools, so my circuits are always on normal, homemade pcb. Btw: nice set of tools I can see in the background ;-)Anyway: nice work, I like it 120%. You have a new follower ;-)

Uh, and nice project BTW! I was thinking about a "holiday feeder" as well, but it is way more complicated... Your solution is definitely better! I will try it with some wood or foam since I don't have access to a 3D printer.
You could put a power bank in between. Just make sure it can charge and provide power at the same time. Or, if a short power loss and a reboot is acceptable add a relais (2× switch) which is powered by main power and if it turns off, the relais will shut down and close the circuit with battery power. If main power returns, the relais will turn on and switch back to main power. This might be a bit less efficient, but is easy and straight forward. You could even add a huge capacitor to the mcu to bridge the short power outage...
