I have been watching all your videos this past year and I have enjoyed them very much. However, I just stumbled on this video and I LOVED IT!!! I am new to electronics and have honestly stumbled around trying to decide what kind of project I wanted to work on until now. I’m going to get this module and maybe try to build my own. I hope you revisit this topic at some point.
Interesting... then ones I have put out a nice 5 volts with an 18650 li-ion on them... well, it’s like 5.05 or something like that, not 0.5 volts high. I use them for some of my arduino projects. I wonder if it’s because you started it at 5 volts, then dropped them down, and it never reset itself. To add on to what you said about the minimum input voltage, that depends on what the gate/base needs on the mosfet/bjt to turn on, also there is an internal voltage reference, and it needs to be able to produce that so it can regulate its output.
Yup that work work, but you would need a LDO and since the 5v is not stable, it would drop below dropout voltage nearly for sure. If you need a specific stable voltage, you should probably take the efficiency hit and boost up higher and use a linear regulator down to 5v
You definitely want a module with adjustable voltage and current, like this one: rover.ebay.com/rover/1/706-53473-19255-0/1?ff3=4&pub=5575582724&toolid=10001&campid=5338675657&customid=boostbuck&mpre=https%3A%2F%2Fwww.ebay.ca%2Fitm%2FCC-CV-Adjustable-3A-35W-DC-DC-Buck-Boost-Converter-Power-Supply-Module-HI%2F183990721350%3Fhash%3Ditem2ad6b39b46%3Ag%3A1uEAAOSwkRRdn%7ERn . It is a bit more expensive but you can do a lot more things with it!
So I retested mine, and at 4.2 volts in I get 5.2 volts out, still within the tolerance range of arduino, since it can handle 5.5 volts, and most sensors have similar if not higher tolerances. Also, after much googling, I found this chip, on the page it has a data sheet, and that data sheet says the max v_out for these should be 5.1 volts. So they seem to be a little out of spec. Oh well, work good for what I need. www.sunrom.com/p/bl8530-501sm-e5-5v-sot89

Thank you for the kind words!!
I never even thought about them. Just wackem in when I needed to. Thanks to you, I will never look at them the same anymore. Lol.
Glad I could....help? lol

Hmm. Output via a 5v regulator if exact output required, perhaps?
Just a thought on a "because we can whether it makes sense or not" basis :)

Looking for a good step up to 5v in order to use with a supercapacitor. Any idea?

Good job explaining for non-techs like me.
Glad it was clear!
2 aa battery in series and 18650 with tp0456 with boot will get 5 volt
Interesting

So you're saying it's not magic? Because I always assumed it was just magic.
Any technology that is sufficiently advanced is indistinguishable from magic
