yes fail safes are nice. fuse everything. mishaps happen!
Thanks Julian 🙂
Why do not you make a monthly competition for audience/subscribers ? 🙂
Everytime, ask for a certain project to be smallest or faster or simplest or cheapest…etc. for a certain class of audience/subbers; kids, young ones, midagers, old timers, females, college students….etc.
Prizes, just give them some of the modules, that you do not need ;D
nice
The symbol you use for a voltage source belongs to a current source!
you could make up croc clips on those open ring connectors to attach different outputs easily
Really enjoying your commentary throughout this video.
What a wonderful talent you have smoothly communicating without a script what’s in your head. Your a joy to watch Julian, I gain so much more from this than a straight forward instruction.
As others have indicated, well done old chap. 👍
Very nice video! Hooray for solar, but I also like seeing the less chatty style with more concise information and not wasting viewing time on mundane things. Thank you Julian, looking forward to see the rest of this promising series of videos!
Will you think about making your own PCBs with something like eagle and then developing them 🤔 if just started working with making my own PCBs 😊
Add some discrete logic that will prevent the two MOSFETs from being on at the same time. The fuses will be fine for current limited sources but not in a final product or design where it can't be guaranteed. So basically:
H=horizontal series FET
V=vertical shunt FET
RA0=micro H output
RA1=micro V output
so
H=RA0 // always follow
V=RA1 AND NOT RA0
That should prevent both FETs being on at the exact same time and causing a "short" circuit. It doesn't matter what the micro controller says to do or what startup conditions it is in or if the controller "crashes" and gets off course. Much safer.
Tripod, tripod, tripod… 😉
Doesn't that camera have an video stabilizer mode? If not a regular video camera will and would be better for your moving about shots.
Julian, awesome! I want to do more with solar but I have too many projects on my plate at the moment. Also, that's a really cool breadboard and I love the LRF support. ;D
That upside down, lone resistor would trigger my OCD and cause me to break out the SMD gun to flip it right way round!
Curious that you aren't using any banana cables for your testing setups. Mine are mostly those cables in all colors of the rainbow when I try something, because they connect and disconnect easily and have no problem up to 10A (I've also driven them with 20A, but the plugs tend to get a bit warm at that point).
If you put a 1k resistor to ground on the gate of the mosfets so they are not floating they shouldn't turn on unless you mess up with your code. Thanks for all the great videos.
An led in parallel with the polyfuses might be a good way to spare some headscratching
Hmmm, now I know why lights blink on spaceships…
