#diode — Public Fediverse posts

Faire #clignoter une #diode #LED avec une carte #Arduino #Nano ou uno n’était jamais compliqué mais la #simuler sur #SimulIDE est un vrai #défi ! Mais #Electro & #Robot, tout est possible, nous vous proposons une #nouvelle fiche d’activité (la 50ème sur notre #portail d’apprentissage en ligne) pour #debuter avec les #cartes #programmables sans l’acheter 🧑‍💻👨🏻‍💻

Vous créez votre #premier #montage #électrique, ou vous utilisez pour une #première #fois un témoin #électroluminescente et vous souhaitez connecter une #diode #LED à votre #système ? Electro-robot vous met à disposition une #calculatrice pour déterminer la valeur de la #résistante #R en fonction de votre #alimentation #électrique #VCC et le #courant maximal admissible : https://electro-robot.com/electronique/calculatrice-de-la-resistance-en-serie-pour-une-led

#Connaissez-vous les #diodes ? Saviez-vous qu'une #diode est #composé de deux #dipôles : #l'anode et la #cathode et qu'elle ne #laisse #passer le #courant #électrique que dans un #seul #sens ? Alors quel est ce #sens de #circulation? dites-nous dans un #commentaire quel est ce #sens de #circulation et découvrez avec #electro-robot d'autres #types de #diodes telles que les #diodes à #Zener, les #diodes #LED, ...

My #BMS #PCBs arrived from @aislerhq and they look nice. I designed it because I couldn't find 3S BMS for #LiFePO4 cells and didn't like the voltage thresholds of the cheap #LiIon ones.
It uses the #BQ77915 chip from #TexasInstruments. Size is 63x50mm.
While fetching all components according to the BOM, I noticed the #diode had the #footprint SOT-323 assigned. I only have SOT-23 ones :blobcatgoogly:
I'm glad that I can still make it fit, and the third leg isn't used at all (it's a single diode).
Can't wait to find some time to finish soldering a few and try them out.
It supports 3S up to 5S, and I added #silkscreen part to mark how it's configured.
The back has detailed instructions, so I don't forget them.

#1N5817 Schottky Barrier Rectifying #Diode is one of many #semiconductors powering modern #technology.

#Faroese word for it is #hálvleiðari (#hálv - half-way + #leiðari - conductor), while #electrode is called #kleiv - a word that originally meant a "narrow cleft".

I do have a 1N5822 Schottky

Comparing datasheets
SK26 60V 2A
1N5822 40V 3A

The voltages on this side of the switch mode power supply are not expected to be much higher than 12V DC. This wall wort is rated at 600mA 7.2VA. The electrolytic caps are only rated up to 16V

Will it work?
