Hello tech nerds, I'd like to know what kind of optoelectronic measuring device my brother built here and what purposes it can be used for? Unfortunately, he can't answer this question himself. Note: He's been involved in astrophotography (planetoid observation) and UV laser applications. Thanks so far. The upper value is "Hertz" The lower my/mc2…
Hello everyone, I'm looking for a function generator that can display filter curves or the frequency response of an amplifier on an oscilloscope. Which connections "Sync" and "Output Signal" does it need for this? A link to a suitable function generator would also help. Should of course cost less than 1000€.
This is a humidity and temperature sensor for the ELV wireless climate station. Which is the temperature sensor? The humidity sensor is definitely the square thing U5 with eight legs next to the spiral antenna. There's nothing at U6. Where is the temperature sensor, or is the square thing U5 a combination sensor?
So what components are inside? And is the voltage or current limited? What happens if you connect two speed controllers in series?
Hello, I have a question about a fuse. The fuse on my Fluke multimeter blew, so I wanted to order another one, but unfortunately the correct fuse is either far too expensive (€40-€70) or no longer available. I'm currently using a 10.3x35mm 600VAC 1A fuse, so my question is whether I can install a 10.3x38mm…
Hi everyone, I found this measuring device in the basement. I've already asked a few people what it's supposed to be, but no one has been able to help. I would be happy to receive an answer. greeting Manfred
Hi, I'd like to add a small measuring device to my sit-stand desk that displays the current height of the desk. I only have a toggle switch, but I often need identical heights and don't want to keep checking with the linear scale. Any ideas?
Hello, I'd like to buy a multimeter. I'll use it for computer hardware like motherboards, graphics cards, and the like. I'm not familiar with this, though, and I don't know which multimeter is good or bad. Can anyone recommend a good one? Something under €50 would be good.
What is a 6 volt power source? So you have a constant 6V for every current value? Would that give you a source voltage, and what else do I need to know about that? What would that mean for the circuit? And how would you indicate it in the circuit?
What's the point of calibrating the probe to the test signal if it only delivers 1 kHz (most of the time)? If I then measure something with a different frequency, it's completely pointless, right?
Speed indicator evaluations, such as this one ( https://de.wikipedia.org/wiki/Geschwindigkeitsanzeigeanlage#Technik ), include data recordings of how fast vehicles passed by. I'm interested in how these values are recorded. Is the highest value per vehicle saved, is an average calculated, is the last/first value saved, etc.? Unfortunately, the person responsible for the evaluation couldn't answer this question.
Hello. I was recently at an apartment clearance event and found an old tape measure. Unfortunately, I can't find anything about it online. Perhaps there are some experts here who can help me? I tried to make the images as sharp as possible. Unfortunately, the text is no longer completely legible.
