Musical Sugru Ear Defenders
With 2 lasers now running in my garage the pumps and fans can really drone on (I'm yet to box them in to make them quieter). I've been wearing my ear defenders quite a bit recently to help keep me sane (and to keep my ears warm) but I also like listening to music while I work and the two are not very compatible. I headed off to the interwebs to see if headphone ear defenders were a thing and it turns out they are. £33 will get you a set of defenders with an audio jack input, being a bit of a cheapskate I suddenly realised that I could add headphones to my £3 ear defenders, have them ready asap and have spent significantly less amounts of money on them.
The process was pretty simple. Drill some holes in the side of the defenders large enough to pass in some ear buds and then hold them in place with some sugru. Job done, everyone has a pair of ear buds kicking around and I picked up the sugru at one of the many maker faires I've been to, so not only did I have a set by the end of the evening I also didn't have to pay anything extra for them.
