I have a BuckBoost powering a project i'm working on. No idea how it works. Now I do.
Awesome stuff Pete. Keep up the fantastic work.
I love these videos Pate. Thanks for starting them back up again!!
Hey Brian! Thanks much. May be planning a trip out to Mpls soon...
Pete Dokter Oh so cool. Let me know and we'll meet up with you somewhere. You can see Adam and Matthew too.

I am so glad to see this again!!!!
According to Pete is my 3 year old's favorite show!!
Hahaha! This is Dixie's fave?
Yep!
I learned all of this at school.... I absolutely loved it! His terminology is awesome!
Bucking made simple -- great work, Pete Dokter!
This was very interesting and informative. For next week, maybe a voltage dimmer for this. Instead of PWM regulating the LEDs videographers tend to want flicker free lighting and thus a variable voltage circuit for the LED panels and whatnot.
I'd definitely like to see building blocks of electronics for those of us that are kinda new. Constant current source circuits, constant voltage sources, soft switches, etc. Maybe we could take as many of them as we can and put them together into a more complex circuit and submit them back to you.
Awesome Job! As usual!
Yes !
Finally it's back !!
Your schematic shows 5 LEDs in series, but you have at least three segments here, and each one has what looks like between 3 and 5 LEDS. Are you using multiple power supplies and circuits? Or the same supply with multiple circuits connected in parallel? Or is your schematic inaccurate (an example)?
My instinct says a 1A or 2A fuse would be an appropriate addition to this circuit.
I'm trying to figure out how the "sense" part of the circuit works. Anyone? Thanks.
What did you use to switch the circuit on and off, was it a simple switch that's hidden away?
Regular ol' switch (well, rated for AC, anyway), hot-glued up under the edge of the cabinet. I spliced the power cable and strung the hot wire down there. I toyed with ideas of gesture sense and all that stuff, but in the end decided that I didn't want that laptop PS on all the time.
What color white are they?
That would be the "warm" white. My wife didn't like the cool white.
nice mechanical pencil :)
