TB6600 4.5A photos without heatsink

A quick post about TB6600 stepper motor driver module. It should be 4.5A version. It has model marking on the back that says “BL-TB6600-v1.2”. This version has no plastic covering and has green PCB. Since originally everything is covered with large heatsink there is nothing much to see before removing it. Here I share some “closer look” photos

CMTP02-5A solar controller photos and contents

This is a small follow up post for my main post (go read that post also after this post) about CMTP02 type of solar charger controller. Turned out that 5 amper version has actually much different content (-5a after model name refers to a maximum of 5 amperes charging current). It’s not actually a surprise since it handles much

WD200EB hard drive taken apart- what electronics can be found inside?

I have an idea to make Arduino based laser scanner show and I need some old hard drives to make axes for it. I had an old WD200EB hard drive laying around. Here I share what electronics can be found inside and how does it look inside. Other than that it’s casual hard drive and

What is inside of the color changing candles?

I have always been curious what’s inside of these color changing candles. These candles start emitting light when lit and colors usually change (nice mood light). Most famous ones are probably Air Wick ones. There are also others out there like Coleman for example. I finally disassembled one to check it out. These candles have color changing LEDs in

CMTP02 – disassembling this solar charge controller

I want to share inside look at cheap Chinese solar charge controller CMTP02 (CMTP-02). I have a 30A (charging current) variant, but it has also 5A, 10A, 15A, 20A versions. It should be a PWM controller. Maybe even not that (like Didier pointed out in the comments section). I have not learned all the terminology regarding
