Plywood – wooden fashioned from skinny strips – is one thing we usually take with no consideration as a helpful constructing materials. Nevertheless, as Zach of All Trades factors out within the video under, the identical idea can (theoretically) be used with different supplies as nicely.
To check this out, he made a curving headphone stand, with a single layer of acrylic sandwiched between two layers of maple on both facet. The acrylic acts as a lightweight pipe for inside LEDs, lighting up the sting based mostly on capacitive contact inputs. The result’s a unbelievable fusion of wooden and tech that took an enormous quantity of effort to get working appropriately.
Embedded contained in the acrylic layer, a sequence of versatile PCBs with PY32 microcontrollers drive the inner LEDs, and reply to capacitive contact sensing through copper tape. These PCBs, in flip, are related to an STMicroelectronics Nucleo-32 within the base for total management and energy provide. The impact of the LEDs shining by the acrylic as edge lighting is spectacular, and it holds a set of headphones properly, although Zach sees some room for enchancment.
Whereas he’s not loopy concerning the colour or sheen of the end – and there was an honest quantity of hole filling with epoxy – he did study a ton throughout the course of, resembling vacuum laminating and dealing with capacitive contact sensing. After all, one may argue that studying is the purpose with any venture like this, and if he makes one other iteration, it needs to be even higher.
Test it out in motion, and Zach’s struggles to get it completed, within the video under!
