You are welcomeWill, what can I say? Thanks for the great info!!!
Yes, I worked from the Data Sheet, made my own schematic on Eagle CAD, did my own layout, ordered my own boards, the regulator, discrete parts, and soldered all of the parts myself. It is very time consuming to do all of it, but it is also fun stuff to doThat circuit you built up looks very cool, did you make the board yourself?
For those of you that want to experiment with the ZXLD381, here's a way to put it on your breadboard:
First, get some breakaway header pins. These could be desoldered from an old computer motherboard (IDE/floppy connectors, USB headers, etc). Stick the long ends in your breadboard like this:
[X] [ ] [ ]
[ ] [X] [X]
Cut a 2x3 grid of copper-ring perfboard and lay it over your header pins, ring side up:
Lay down the ZXLD381. The ground pin should be touching the top middle contact; the Vin and Vout pins should be touching the bottom middle and bottom right contacts. I used a little rosin flux on the SMT pins to ensure good contact:
Apply heat to the copper rings and feed in solder until things ball up. Deliberately create a solder bridge from the top middle contact (where the ZXLD ground pin is) to the top left contact (where the header pin is):
Now you can unplug and plug that teeny tiny SMT chip anywhere on your breadboard you like, because now it's a through-hole component!

Sorry to dig up an old thread. I did google extensively on LED, Joule Thief, vampires, SMD, etc and found this & other post. Unfortunately, most of the image hosting link are no longer valid. Hence, my attempt to contact the poster about the smart way of doing some SMD.Aw I thought there was some action on this old thread. Just another Necro... Google that one kids😁
