This guide, Laptop Motherboard Failure Analysis Matrix , presents a failure-analysis table that links common laptop motherboard problem areas (subsystems) to the components most likely to fail and their typical causes. Here is a cross-checking combi…
Here, I will demonstrate how to perform a differential measurement in Proteus using the oscilloscope math function (Add and Invert). This process mirrors actual physical circuit measurements, and I'll use an inverter's output as an example …
In this short tutorial, I will show how to create custom diode simulation models in Proteus using spice model. You will learn SPICE modeling, subcircuits & error-free setup. I tried to create simulation part for UF4007 for use in proteus simul…
Lately, my working Arduino Nano started to overheat, and the ICs on it became very hot when connected via USB. I don’t know the reason. In fact, I now have two Arduino Nanos that are not working anymore. The other one does not have the overheating …
About three years ago, I built and manufactured a DIY Arduino board with a custom PCB design. I created the schematic and PCB layout myself and had it fabricated by NextPCB . They were generous enough to manufacture and provide the board free of cha…
In my earlier Ubiquiti radio antenna repair note repairing Ubiquiti Lite AP 120 I said that I checked the various components on the PCB board. I checked the voltage regulator IC, the capacitors and inductors for any short circuit. I also posted U…
I do many circuits design and simulations in Proteus and it is a great software but with complex circuits such as RF circuits, power electronics circuit and other high-speed switching circuits at configured at high frequency, it just crashes. Actua…
