DuB-EnG: Digital Vernier Caliper Use, Repair faded LCD display and a brief overview of How It Works

[@8bitsinthebasement]

Intresting fix, I was given one as a gift a few years back. Great little devices, I use mine much more often than I thought I would. I will take your advice and leave it slightly ajar in its box. I was unaware of the corrosion issue. Thanks Howard ;)

That little rubber protector helps!! Maybe you could just keep a little paper between them! ... I’m off to see your z80 upgrade video in a moment :-). Looking forward to it!!!

Nice, detailed video. I dismantled an identical caliper to clean the button contact points. A tiny "L"-shaped copper strip with a hole in one end fell down, and I could not find where it belonged. I put the caliper together without that part, and it works fine. Could you please let me know where it should go?

Oooh... I wish they had pictures on this forum... Can't easily help without pics

a great little repair , i wonder how many more people have one of these tucked away in a drawer somewhere , all but forgotten , with the same fault? I am surprised that whilst you had it in pieces you did not take the opportunity to upgrade it - maybe replace the buttons with missile switches??

[@DubiousEngineering]

Hahahah.... the other guys suggested tiny Nixie tubes ... but then they noticed how many angry people came out of the woodwork!! :-)

[@Keeping_IT_Simple]

@@DubiousEngineering but that's why Ronseal have just released there anti-angry wood preservative range!!

[@DesmondsDonders]

Neat fix. Take care and stay safe.

[@DubiousEngineering]

Thanks, you too! ... Spring is nearly upon us!

[@danielthomas9889]

Should have stuck some nixie tubes in it and turned it into another clock :-p love you Howie

[@JackBealeGuitar]

Bit late to the game 😁 but please, it's NOT a vernier caliper. It's a digital caliper. Vernier calipers have a Vernier scale for reading tiny fractions of the units used (say, down to 1 thousandth of an inch). It's a particular use of the word. Without the Vernier scale, they're not Vernier calipers, which sadly will fade into the horizon & be lost to the past. Anyway, I actually came here to say thanks for the vid. My caliper display was only illuminating partial digits, not all sectors of the display. I disassembled it and everything just fell out including the zebra which had me baffled...it just looks like a slip of plastic but looking at it under a microscope I could see these laminations. I couldn't see how the LCD was connected to anything! Your vid sorted the whole mystery, and it went back together perfectly, works 100% I had to do a little manipulation of the zebra connector to get the "strips" lined up & connected to all segments but it's great. Thanks a mill!

[@DubiousEngineering]

You're absolutely correct!!! 😊💯 ... And I consider myself a metrologist!! Silly boy 😉😅

[@lactobacillusprime]

Nifty fix!

[@DubiousEngineering]

thanks man... all the very best! :-)

[@meromeropachanguero]

hola, donde puedo comprar el display??

[@DubiousEngineering]

Hola! Sorry no idea!

[@JackBealeGuitar]

You're much less dubious than you make out. I'd have lost it half way and binned all the bits 😂. Admit it, you love saying zebra connector

[@DubiousEngineering]

Is that... Zeeeebra connector in American :-)
