I don’t know what it will need to have value, however I’m assuming peanuts.
Reporting to you right now from the bizarre a part of the web, we’ve acquired loopy YouTuber Penguin DIY who determined to take a walnut shell and cram a complete Bluetooth speaker inside it… USB-C port and standing LEDs included. The speaker’s audio high quality isn’t something to write down house about, however the video above that exhibits the complete development course of won’t (I imply walnut) disappoint.

The speaker itself a miniature little machine the scale of a… nicely, walnut. Produced from the walnut’s shell, it packs all the required parts inside, together with a mini battery, amp, driver, Bluetooth module, USB-C port, and even buttons and LEDs to regulate playback or enhance/lower the amount.
The method concerned emptying out the contents of the walnut earlier than taking a Dremel to the within of the walnut shell to make as a lot house as attainable for the parts. The parts embrace a 5V energy financial institution module that was stripped for components as a result of it was too large to suit into the shell. The module (or no matter was left of it) was then related to the remainder of the speaker’s components, together with a 300mAh battery pack and a USB-C port for charging the speaker.
Different parts included the precise ‘meat’ of the speaker, together with a 2W audio driver, a mini-amp, and a Bluetooth module to permit for wi-fi connectivity. All of the parts have been slightly intricately pieced collectively and soldered with what I can solely describe as unbelievable dexterity for one thing that small, after which glued to the shell with silicon glue. This versatile glue would enable the motive force’s vibrations to happen with none hazard of dislodging components contained in the walnut shell.
Lastly, holes have been drilled into the highest of the walnut to make means for the speaker grill, management buttons, standing LEDs, and even a nifty on-off change. Within the curiosity of repairability, Penguin DIY assembled the 2 halves of the shell along with screws as an alternative of glues, enabling him to open up and restore or improve the speaker at any time when he needed. Let’s face it, if a YouTuber can flip a walnut right into a Bluetooth speaker and nonetheless make it repairable, Apple could make the AirPods repairable too.
The outcomes are spectacular however not for the explanations you’d assume. The speaker works flawlessly, with it being detected on a smartphone, getting related, and even letting you play/pause music identical to any common wi-fi speaker. Understandably, the sound isn’t notably nice due to driver, amp, and dimension limitations… but when I needed to fee the speaker on a scale of 1-to-10 for sheer ingenuity and for its proof-of-concept, it will get full marks. Actually, neglect pumpkin carving expertise, Penguin DIY’s walnut carving expertise are completely on level!
