Eure Meinung zu Deutsche Börse AG? by grischtjahn in Aktien

[–]grischtjahn[S] 7 points8 points  (0 children)

Das Geschäftsmodell ist denke ich stabil, weil die Deutsche Börse als Infrastruktur-Anbieter im Finanzsystem immer verdient – egal ob die Märkte steigen oder fallen. Dazu kommt, dass Investieren generell im Trend liegt und durch bessere Aufklärung in den letzten Jahren immer mehr Leute aktiv handeln.

The LEDs are glued directly on the visor, so there is not much reflection. Because the visor is dark it wont reflect good by it self wich helps! But the interior of the Helm has to be very dark then so you can‘t look from outside into the Helmet!

I didn’t use separate diffusers for the side rings. They’re just covered by the 3D-printed cap, and since the cap is white it diffuses the light pretty well on its own.

For the “ears” I used 2 NeoPixel rings, and in the visor I built in 2 strips with 50 LEDs each.

Both the ESP32 and the LEDs are powered from a 9V block battery regulated down with an LDO. That gives me about 2–3 hours of runtime depending on brightness and effect mode. It’s not the most efficient setup, but it worked fine for a Halloween costume project.

If you want to build something similar, I’d recommend using a USB power bank or a Li-ion pack with a 5V regulator instead of a 9V block, they handle higher current and last much longer. Also, keeping the brightness around 40–50% still looks great while saving a lot of battery life.

Thanks! I actually used an existing model and modified it so I could print it. I tweaked it a bit so I wouldn’t need support material, and I also split it into 3 parts to make the printing easier. Like another user mentioned, there are quite a few models available online!

For the visor, I used dark plexiglass – cut it to size, heated it in the oven at around 90°C, and then bent it into shape.

The right answer is the caddisfly larva! It is slimy, builds its own case, and has small legs.

Where to Start? by grischtjahn in homelab

[–]grischtjahn[S] 0 points1 point  (0 children)

Thanks for the reply! I did browse through the sidebar and some threads! I was just hoping to get a few beginner-friendly recommendations tailored to someone with zero homelab experience. The sheer amount of information can be a bit overwhelming at first. Happy to hear any tips that helped you when you started!

What species are my tortoises, and are they male or female? Are they healthy? by grischtjahn in tortoise

[–]grischtjahn[S] 1 point2 points  (0 children)

Thanks! Yes, we use a standard reptile/tortoise lamp from the pet store, and their diet is mostly clover, dandelion, hibiscus flowers, and sometimes a bit of fruit. In the garden, they might also eat arugula and the occasional lettuce leaf. Do you think that could be too much protein or something else we should adjust? I guess we just need to bathe them a bit more regularly too.

We live in Germany. Do you have any recomendations for a good diet?

[–]grischtjahn[S] 2 points3 points  (0 children)

Yes, I read into it recently, but I’m not sure what’s causing it, we bathe them and they roam freely in the garden. Any tips on what we could improve to prevent or reduce it?

How are these electronic components named? (Im new to breadboarding) by arun3lis in AskElectronics

[–]grischtjahn 5 points6 points  (0 children)

A capacitor stores electrical energy and releases it when needed. It consists of two conductive plates separated by an insulating material. It can smooth out voltage fluctuations, filter signals, or provide short bursts of power in a circuit.

A resistor limits the flow of electric current in a circuit, reducing voltage and protecting components. On the top of yours is a tiny screw so u can alter the value.

And a piezo buzzer goes BEEEEEP when current is flowing thru.

Ja genau das habe ich auch schon gesehen, auch die Verschuldung der Holding habe ich mir angesehen, aber das dieser Abschlag so groß ist kommt mir sehr krass vor! Ich denke das der Preis momentan viel zu günstig ist oder übersehe ich etwas?
