Hello, Background: Large POE switch (24 ports) that I would like to utilise for home use. These units are normally stored in a server room so noise is not really an issue, for me however, it is. The plan was to replace the existing 3 x 40mm fans with 2 x 120mm fans using my own fan controller...

Hi, Im new here. I have a DC-DC Buck LM2569, powering a raspberry pi 3 model B+ and a 5v Fan. Can someone please guide me. Do i need to put diode to protect the rpi3b+? thanks

I am trying to figure out if I need only one fan for my heatsink or more? I asking cause the fan that I have selected do not cover the entire heatsink area. Does it means that I need to have more fans in order to maximize the cooling from the heatsink? In that case, if my fan needs to have a...

Hello, I hope this isn't too far outside this forum's usual fare. My pride and joy is a 1959 Morris Minor. As you can imagine, it has a pretty simple electrical system composed of mechanical relays and such, and usually I have no trouble working on it. However, I'm homebrewing some upgrades to...

2003 Fiesta 1.25: had problems with the fiesta overheating even though temp gauge says normal temp on dashboard. After box ticking all the usual culprits (relays, fuses, isolating fan to test it works which it does etc) found out it's the ECU ignoring any messages from the temperature sensor...

This is a recurring problem for me. Do I need to use forced air cooling with fans or not? And although I always have this situation, I can never decide what to do, or to put it better I don't know how, on which criteria, should I decide about this. What my designs usually have is a power hungry...

i have a single phase ac fan that i would like to control its speed i am a bit new in this field so please bear with me i had the idea of fixing 3 speeds with 3 switches one for each speed: (25% 50% 90%), and 3 relays each switch activates a relay and each relay wired in series with a...

Since my first thread on this Forum a few months ago quite a lot has happened. Firstly I must thank spec for all is help and advice. He has the patience of a saint and can come down to the level of a moron.:):oops: Secondly a slow realisation of what building a power supply means has occurred...

This is my first post, so sorry if I'm noob-ish. I'm trying to figure out how to find the RPM of a small DC brushless fan. I'd like to try to get it figured out with an oscilloscope. I'm having a hard time finding a good way to do this. Does anyone have any ideas on how I could do this? I'm...

Hi! In order to cool a telcom device I am using 4x 12Vdc fans from Delta Electronics (the exact type is FFB0412VHN-F00). The fans have a 3-wire interface and I operate them by sending PWM pulses at their power supply wire. The pulses are generated from a PIC-microcontroller and are "converted"...
