I've used this unit in previous videos, and some of you wanted to see what was inside. I don't recommend taking these apart, as it is quite destructive. If you have a use for one of these then they are available from AliExpress and other online marketplaces:- https://www.aliexpress.com/item/1005007659036369.html The cost should be around £6, and if you browse them then they may appear in the bundle deal section of their site. If you enjoy my videos and wish to support the channel to keep it independent, you can do so by supporting me on Patreon. I release videos without adverts for critique and feedback on Patreon as soon as they have been made. I also release Patreon-only backstage videos when I'm working on shows. https://www.patreon.com/bigclive Alternatively, for a single contribution you can use PayPal:- https://www.paypal.com/paypalme/bigclive #ElectronicsCreators Mon, 13 Apr 2026 13:18:57 GMT https://validator.w3.org/feed/docs/rss2.html PeerTube - https://stream.echo6.co https://stream.echo6.co/client/assets/images/icons/icon-512x512.png https://stream.echo6.co/videos/watch/489c62fc-5e97-47cf-ba7e-adc2f89664a9 All rights reserved, unless otherwise specified in the terms specified at https://stream.echo6.co/about and potential licenses granted by each content's rightholder.
