DuB-EnG: LOUD MEGAPHONE - How it works - Repair, Restoration, Test and Review - WARNING LOUD

I bought this old vintage megaphone on eBay - it didnt work, so I set about taking it apart, learning how it works, repairing it and testing it. This was a great fun project and quite educational!! I believe my wife would like me to sell it now.... :-)

Interesting to see how it worked, quite clever design. I noticed a rendition of the "Hill Street Blues" TV cop series from the 80's, You might not remember that series as I'm old

Hi Colin... it’s funny... I was noodling around on the piano and someone on Twitter said I had made some old school TV cop music. They then suggested I look up hill street blues theme. I then couldn’t help but make my own version :-). I’ve never seen the show but the music is quite moving!!

[@BenScarboro]

I’m very glad you do things like this... I’d be shot very “concerned” looks and the phrase “well, it is your money” would be banded about if I ordered things like that ;)

[@DubiousEngineering]

It was a shed load of fun!! ... but youtube is trolling me with loads of ads. I clearly need to adjust my settings... sorry 😐

[@BenScarboro]

@@DubiousEngineering I just have gotten lucky, no ads for me when watching that video!

[@DubiousEngineering]

Actually happy days... I had a run of three in a row ... and got quite frustrated. I’m going to see if I can switch to one at the front and one at the back only. Hmmm

[@mozquito76]

Love that - funny and awesome uhh, the magical Schmitt-Trigger... keep going ;)

[@DubiousEngineering]

It does sound similar to a rude word!!... :-)

[@IgorKolar]

No, no, it works, it's just a misspelling, it's not 'automatic' siren, it's 'autonomous' :D awesome :D

[@DubiousEngineering]

Hahaha... thanks Igor!! I knew it had to be something simple like that ... and silly me changed all those capacitors to try to fix it!!! Pah!!! :-)

[@RhythmGamer]

Learned something new and had a nice laugh 😆

[@DubiousEngineering]

Thanks 🙏 for watching... glad it was mildly educational and slightly interesting. I need to adjust my settings, KZbin is clearly flogging my videos with lots of ads. Sorry about that...

[@techman2471]

A little bit of Riders on the Storm" in there at the end, eh?

[@DubiousEngineering]

Well spotted David!! ... a very chilled rendition :-) hope you enjoyed the video ... it was a lot of fun making it :-)

[@pup4301]

Nice fix.

[@DubiousEngineering]

Thanks PUP :-). It was a longer harder road than I expected... but worth it in the end!!!

[@DesmondsDonders]

Please tell me you are not taking that in the camper LOL.

[@DubiousEngineering]

Haha... can you imagine how potentially obnoxiously good fun that would be at 11pm on a municipal campsite 🏕

[@DesmondsDonders]

@@DubiousEngineering Love the phrase obnoxiously good fun

[@mozquito76]

Try to Bass-Boost the Cone :D

[@DubiousEngineering]

That would be fun!!

[@jiversteve]

Something inside so wrong!

[@DubiousEngineering]

There’s a song in there somewhere!! ... sorry about all the ads... I clearly need to adjust my settings. KZbin is flogging me!
