C’est beaucoup mieux que les autres apps que j’ai testé et surtout elle est adaptée aux tablettes, par contre les prix sont un peu élevés.

if you have an emisar light and can disassemble it, then you can try soldering an airwire from the sense resistor to the button LED pad (sacrificing it for that) or a free ADC pin, but that’s more difficult. If that cause problems with the current regulation, add a 10k resistor or the likes.
with a linear driver Iout=Iin so it’s simple, with a boost driver Iin=(Vout x Iout)/(Vin x efficiency), thankfully Vin is already bein measured, Vout and efficiency need to be guesstimated.

I cleared the cache multiple times

And cookies ? I had to clear cookies after the hack the other day.

Ah oui ? J’hésitais à passer au manga mais je vais peut être essayer de me retenir du coup, surtout que la 1ère saison était très bien réalisée.

Nice work, thanks for the diagrams.

Mouser/farnell. Coilcraft inductors are quite expensive yeah, but often there are lower priced equivalents, or when possible a larger size/cheaper model can be used

I already know someone who could machine parts for me, so yeah I should start designing something.

Haha thank you, I wish I was able to make my hosts.

“oh yeah, I made an aux board too” 😂

Naturally 😁

And thanks!

I see, looking at pictures the tube is screwed down against the pill, I guess the pill must have some kind of hard stop when screwed down so that it doesn’t change position, as opposed to say and S2+ where the pill compresses the oring thus doesn’t have a hard stop.

Unrelated to OP but commenting here since it’s about reddit. Did you notice that mentioning Lemmy on reddit gets your comment shadow removed ? here’s two of mine I just noticed thanks to this AMA about Revedit

I’m curious how the head and tube perfectly align for the one on the right (Citadel ?), I’ve seen it before and thought it looks really great. Although I wish these nice lights were more compact, they look fairly large for the size of the cell.

Thanks.

That plating process looks like a real pain, any benefits over using a copper pcb to begin with?

None except cost. When I started this project a DTP MCPCB would have cost in the 300-400$, but since the start of 2023 JLCPCB is offering a DTP MCPCB service for 50$ base price which is much more reasonable, for a large MCPCB like this I would use this service now. For a small (single/few LEDs) one off MCPCB I might still go with the plating route since the alu MCPCB is so cheap.

Thanks.

Thanks

although I think these drivers could become very expensive and once the manufacturers start substituting components it’s efficiency could decrease.

The buck ICs I used are actually not very costly, the inductors are a bit pricey but since there is quite a bit of free space on the board, (and unused stuff for low side sensing because I made it both high/low side sensing) larger cheaper Chinese ones with similar specs could be used and the performance would be unaffected.

Generally that’s what I would do if contracted for a driver, for example I made my BST21 one sided and 0603 min size for easier self assembly, due to that I used a 70x0 inductor size (~7.5×7.5mm, variable height), which if it was Chinese branded would not have satisfactory specs.
If asked to design a similar driver I would use a larger 1040 inductor (10×11mm×4mm, common size used in Convoy drivers) that are even a bit better than the Bourns/Coilcraft 70x0 but cheaper, the driver would need to be double sided but produced in large quantities this doens’t have a high cost. The converter IC can’t he be substituted, the only other power component would be the RPP PFET but there are a few pretty good chinese ones like the one used in Noctigon boost drivers.
