This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as... -
Hi!!
Yesterday I was installing a new Wifi thermostat for my domestic gas water heater model Vaillant 242/2-3, and accidentlly one wire from mains touched one wire from the thermostat output contacts. This shut off the heater so I finished installing the thermostat and then went out to check the heater
I found one fuse blown (T2 250V). Replaced it with another equivalent fuse and it blew right away. I measured L-N in mains input and I sometimes got 4K but sometimes, not sure why, I got 100 Ohm...
At a certain point, moving stuff around, I put all wires back in place and... -
Hi guys. I have an question. Overall i am currently selling my house ( apartment with 1 room ) to buy some cheaper with 1 room too, and save cash for new pc in autumn 2024.

I've got this circuit that I've been playing with on a breadboard. I'm not happy with it mainly because the MOSFET gets too hot and generally controlling the temp of the heating element with the Arduino has proven to be a little more cumbersome than I would like.
What I would like to know, is what is the best way to set up a circuit like this? The heating element is just a PCB and its going to be mounted under a 3D-printed enclosure that a lizard will use to warm his belly.
This is the general setup that I have now.
This is what the... -
Mounting and Handling Guidelines for TO220 TO220F TO247 Cases / Packages
The TO220, TO220F and TO247 are the popular packages for power devices because of their versatility and ability to dissipate moderate amounts of heat. This application note describes the basic guidelines for handling power MOSFETs in TO220, TO220 and TO247 packages shown in Figure 1. Please note that only mechanical and soldering guidelines are covered here. Additional precautions are required for isolating high voltage rated devices to meet safety regulations.
