  I believe that regulator output has touched the heat sink which is directly connected to the collector of the big transistor which caused that Cap to blow

  That regulator for the fan made contact with the copper from the cooler and got shorted because you didn't isolated the board under!  🤣🤣🤣

  The best way  to learn electronics is this building something from zero. Nice one

  For 37 years, I have been involved with electronics.<br>You just taught me something.<br>&quot;Toothpick&quot; &lt;----- Sir... Thank you! Sometimes that is so frustrating trying to move solder away from a hole.

  It&apos;s not only you, when I try to build something to show someone, sometimes I have such &quot;luck&quot; as well.

  I built that kit in 2019 - building it into a housing and added 10 turn pots and a Volt/amp meter. &nbsp;And it works great !! &nbsp;Best thing ...... unlike many of the constant current power modules &nbsp;you can buy - this one actually does a great job with current limiting !! &nbsp;It actually limits current down to 2.5 mA. &nbsp;Great for power injection and testing diodes !!

  It&apos;s funny... you went from &quot;Electronics Repair School&quot; into &quot;ElectroBoom&quot; in this video... loved it Sorin... :)

  Gotta love the fact that your videos are so &quot;organic&quot;. You also include fails along so we can learn from that, coming to a conclusion in the end and learning a new fix or a new way to blow up electronics, haha. Keep it up, Sorin! Looking forward to the next upload. Have a nice evening :_Lovee:

  The little buck converter board was sitting right on top of the copper heat sink. Wild!:face-blue-wide-eyes:

  i built two of the power supplies powered up and op amps burned up &nbsp;so i change op-amp to lm741 because higher voltage rail and use dip sockets. i also also use 2n3055 as output transistor. used if for five years now

  <a href="https://www.youtube.com/watch?v=DbwtjbaTtUE&amp;t=815">13:35</a> - Strange thing you didnt stop video recording and check what sparked. Its power supply for fan, little capacitor. <a href="https://www.youtube.com/watch?v=DbwtjbaTtUE&amp;t=759">12:39</a> spark.<br>I believe that green pcb touched heatsink, and heatsink is soldered to the back of that big transistor. <a href="https://www.youtube.com/watch?v=DbwtjbaTtUE&amp;t=1109">18:29</a> you placed isolation tape on back :D

  the big transistor collector (probably 20V) touch the &quot;ground&quot; from your 5V regulator and blow up the track and the tiny regulator
