An upcycling project to get your cassettes back from the basement into your livingroom.

Similar projects worth following

In the last few days I have finished the article for the pxlBlck_CassetteLamp. This lamp is a little homage to the time when music was not on a 512GB micro SD card but in the form of audio cassettes. 

I thought it was a shame to let the cassettes gather dust in a box in the basement and made a small decorative lamp out of them. With the help of a few # WS2812 LEDs, an ESP8266 and an old USB power supply unit, the pxlBlck_CassetteLamp can be built. 

With the help of the pxlBlck plug-in (infos here:, the lamp also gets a few SmartHome functions and can thus also inform about events in your SmartHome. In addition to the setting options via WiFi, the lamp can also be adjusted with the help of a pen - just as the cassette tape salad used to be wound up. You can find the build instructions including a list of needed materials and detailed pictures on my blog at

I have a significant number of TDK metal 'reference' tapes (MA-R 90's bought new back in the 80s) and they would look great with this setup. Previously I thought about building an illuminated tower of old CDROMS .. all stacked up with a light running through the middle but at the time had nothing like the WS2812 LEDs or even microcontrollers .. maybe I'll try that idea in the future.

That's a very cool look. 👍 Lucky you with those pristine cassettes. Even if I had any cassettes now they'd all be worn out from constant playing. Of course you've heard recent news that the inventor of the cassette, Lou Ottens, died.

That's a great look! Something totally normal, yet has become vanishingly rare. I grew up with cassettes yet didn't recognize them here on first glance.

Thanks. :) Yes especially when its dark and the lamp is lit its not directly visible that the lampshades is made from seperate cassettes. Could imagine that it becomes more visible if transparent and semi-transparent cassettes would be mixed. :)
