At this point, I had a disassembled DVD player and I knew the audio amplifier and its pinout. Also, voltages on the power pins looked okay.
It was time to test it using my phone, an AUX cable and awkwardly holding three wires on the 3.5mm jack connector - but IT WORKED! The audio circuit is STILL ALIVE AND KICKIN’!
The DVD player, which I used as an audio amplifier, was now broken and I was left in silence. However, all the power and audio electronics were on a separate board altogether and were probably intact. What if I could just use that part of the circuit (instead of buying another amplifier) and give it a new home, a new housing, like a cooking pot. Because why not.
Sometime ago I found this old DVD player and a set of speakers, which I used for listening to music, for years. If I turned off my laptop, which was connected to the AUX input of the DVD player, it would make this annoying sound. Can’t remember if it was high-pitched squeeching or a low-pitched hum, but anyways I ended up turning off the DVD player everytime as well. But for this, I would have to…STAND UP AND PRESS AN EXTRA BUTTON, so something had to be done about it.
How to make a better version of the cactus? Honestly, I’m afraid to even touch the first one: it flips over easily, diffuser caps fall out sometimes and half of the lights don’t work anyways. Improving on this shouldn’t be too hard.
