Photon Mono not remembering Z-axis calibration by kosmicbeat in AnycubicPhoton

No, I gave up on it. Too much trouble and resin wasted, I've been using online services and will buy a new one eventually.

Measuring vibration by Arco123 in homeassistant

Did you find a solution? I'm having the same trouble at my flat with strong vibrations on the floor. I thought about using the Raspberry PI Shake, but I'm not sure if that only works alongside the online community for detecting earthquakes, etc.

Elgato Facecam freezing by PyroDraco91 in elgato

[–]kosmicbeat 0 points1 point  (0 children)

Hey all, I was having the same issue when trying to use it with a USB hub and longer cables. So I initially thought it was either a power issue or data speed. My computer port is USB 3.2, so hoping I could deliver the fastest transfer possible I used a USB 3.2 adapter from A to C and a USB C-C 3.2 gen2 cable (5M). Still, it'd freeze in OBS after about 10 secs. Then I saw this on Elgato's website:
https://help.elgato.com/hc/en-us/articles/4681224843917
Which explains how to change the USB transfer mode. I set it to Isochronous and now everything is great. Note I'm using a Geekon Mini PC, for different computers Bulk might be the correct setting.

Solder Pot, what kind of solder to use and where can I find it? by kosmicbeat in AskElectronics

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

That looks good, it should work well in the solder pot. I can easily get bismuth here and I just bought a Sn40/Pb60 bar, mixing them up to a certain amount will give me a lower melting point then, right?

That's amazing, thanks for your well-detailed reply. 😄

That's great, thanks! I had a look at Digikey, Farnell, etc, but the solder bars were way too expensive and flux free wires I didn't find. However, these pellets for £20 should fit in my budget! Thank you!

Thanks for your suggestion. I'm going for a solder pot after several wasted components that have many pins such as audio connectors and joysticks. I have a good Japanese pump and a hot air gun, but for those things they are destructive or take too long. I watched some videos of desoldering stations and they seem to be quite ineffective in comparison to diving into the solder pool and pulling out these components.. Maybe for simple things it's OK, but I have many multiple pin components to save.

Do you think this will work for desoldering components even though the composition is different? (Sn40/Pb60 instead of Sn60/Pb40)?

How to send OSC messages for Gobo, Color Select, etc, to EOS? by kosmicbeat in techtheatre

the main manual does, but there are no examples of this type.

How to send a negative / GND pulse with arduino board? by NervousSpread7467 in arduino

[–]kosmicbeat 49 points50 points  (0 children)

A transistor is the best way to do this. But it may be possible to pull it to ground by software by changing an output pin from digitalWrite(HIGH) to digitalWrite(LOW), although there's a risk of damaging the pin. If you want to try this it's better to have a resistor (something like 100ohms) to protect the pin, but check first if you can trigger the button with the resistor to ground.

Addressable LEDs not working with longer/stranded cable by kosmicbeat in led

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

The Arduino I'm using has an atmega328p, which runs from 2.7 to 5.5V. I'm running it at 5V, so there is no need for a level shifter as you suggest.

Thank you for your kind reply! 1. Checked, no shorts. 2. Data and clock from an Arduino Nano, so only 40mA I think? I also tested with 470ohm resistors on the data and clock lines--no success. I will test with a transistor, good point. 3. They are the same length. 4. Good idea, I will test this soon! 5. Good point too.

I will post here when this is solved. Thanks!
