[Michaël Duerinckx] was given a turntable for his last birthday from his fiancée — since then he’s started collecting records like nobodies business. But about a month ago he started itching to do an electronics project — he decided to upgrade his record player to include a VU Meter!
As he began designing he soon realized he didn’t have all the tools he needed to do this project right — a perfect excuse to go check out his local makerspace, SoMakeIt!
He started prototyping the VU Meter on a breadboard, and opened up the record player – it was like this thing was made to be hacked. Two free connections off the power supply to power his circuit, bingo!
After figuring out all the connections and testing it off of the record player he finally had a design that worked. It was time to make his very own PCB for it. He’s uploaded the schematic to GitHub in case anyone is interested in doing something similar on their own. Using SoMakeIt’s facilities, and with help from a fellow maker [Dave], [Michaël] was able to etch a PCB to his design, populate it, and test it successfully. Now he just had to drill some holes into his record player and install the LEDs.
Speaking of VU Meters, have you ever seen one this large?
