Well, this project is not homebrewed yet, but ongoing, but that's OK.

I have suffered a set back as one of the EHT winding burned. I will wind it again and then I will keep with the adjustments. Have to find the causes too.

I think you've got things going somewhat better than the original Telequipment scopes.

Back in my schooldays, they equipped the physics lab with a few of them, so I've used them back when they were new.

Here a picture of the scope almost finished. There are some details to solve yet. It will be completely finished soon.

Miguel, I've come to this thread very late, but I've just read through it from the start and can I just say I am full of admiration for your persistence and tenacity. It's great that you are close to the end and I'm looking forward to when you share the completion!

Very best wishes,

Al

Finally I have assembled the "creature". What do you think? I can now declare this project officially (and happily):
COMPLETED

I feel very glad with the result.

Despite having a dedicated thread to thank in this forum, I want to thank here to everybody which have helped me in any way to finish this project.

to all of you: Thanks!

A special thank to my friend Andy (aka Dr Wobble)

You are all invited to the christenning ceremony.

Thank you very much for your words. I still have to print the "manual" of the creature. Just some schematics and pictures of the layout. I will have it ready in a few days.

I am truly, honestly, deeply, deeply impressed at what you have achieved! In overall appearance it puts all of my projects to shame.

You have truly put much effort into this and deserve to be congratulated!

That's fantastic -- and even more so, for saying it's built from scavenged parts.

I'm in awe.

This is how I use the scope. Due to its big size I can not place it transversally so I have to use it oblique. I intend to make a rotary shelf in the future.

How about a 'scope trolley? The best bit is they slope the scope so you can't put stuff on top!

What an inspiration. I have enjoyed every minute spent reading this. In an age where instant gratification is the norm, the guy is a hero.
Well done!
And keep building what next? Trev

The progress Miguel has made in seeing this project through to a successful conclusion is amazing, given that he doesn't have a ready source of components, and the circumstances in which he has to work are far from satisfactory – elsewhere he mentioned that he doesn’t have a workshop – just a small bench in his bedroom. It just goes to show what can be achieved with enthusiasm, commitment and a ‘can-do’ outlook on life. I don't think many people would say to themselves: "I don't have a workshop, I can't easily get hold of components, I know what I'll do - I'll design and build an oscilloscope – why not?"! But he did, and the results are clear for all to see. He started the project in March 2012 and saw it through to a successful conclusion in December 2013.

If that doesn't inspire us, I don't know what will!

Hello all. Thank you for your kind words.

Have to say that a year ago (+/-) I moved the workbench from the bedroom to some kind of shed that my wife and I built. There she has the laundry and I have my bench.

I have improved the oscilloscope during this year and I will open a new thread soon to talk about that.

All the best
