私、機械音痴なんですって英語でなんて言うの？

One phrase I often use for myself is that: I am not a technical person. This means that when it comes to technology, sound equipment, computers etc., I am not very good at it. I hope this helps!

If you want to say you're not good at using Excel or Spreadsheet, you can say, "I'm not great at using Excel/Spreadsheet." You can also say, "I'm still learning how to use this" or "I'm still getting used to this software." If you would like to explain that you aren't very good at modern technology in general, you can say, "I'm not really tech savvy."

Computers go over my head. This is an English idiom that means I do not understand it very well. I personally am not very good at maths and science so I will say Maths and science go over my head Hope this helps Jane :)

"computer savvy" means knowledge with computers. In this case and many others, "savvy" is used to express your expertise in a field. Also in the second expression "I'm (a little) illiterate with technology", I put "a little" in parenthesis because I'm not sure how literate you are with technology so that's up to you to decide. The word "illiterate" by the way means that you can't read. But in this case it's a metaphor to express that you have poor or no skills with technology.

When we are just starting to learn a new computer program or app, we call that person a novice or a neophyte(nee-oh-fyht). You can also say "I am computer-challenged" I am not very handy with machines or computers, meaning you are not good at fixing them or how to work them.

If something is 'My cup of tea' it means that you like or enjoy it or that you are good at it and want to do it. Some people have poor dexterity with their hands so have great difficulty fixing machines - or perhaps even operating machines: 'I'm no good with my hands!' is an admission of this. 'Technically minded' refers to the ability to manage things like computers or electrical appliances.

The noun 'fundi' means 'an expert in a particular area'. In this instance, you are saying that you are not an expert in machines or technology. So, you may say: I am not a computer fundi. The adjective 'conversant' means to be 'familiar with or knowledgeable about something'. So, you may say: I am not conversant with the new technology. In this case, you mean to say that you are not familiar with or knowledgeable about new technology. The word 'savvy' functions as a noun, adjective and as a verb. In the last sentence, you have used the word 'savvy' as an adjective which means to be 'well informed about or experienced in a particular domain', in this case, technology. So, you may say: I am not tech-savvy.

Using technology is really hard for me. I have a phobia for operating technology and machines.

To explain that you are not good with machines/technology, you can say: "I'm not very tech-savvy." "Computers are not my thing."

*I am not techie savvy. If you are techie savvy it means you know a lot about modern technology, especially computers. For example: The state needs more tech-savvy workers for its hi-tech industries.
