Some Seeed products...
Their rather neat-looking Grove "beginner kit"

A couple of the SAMD21 Xiaos:


And some RISC-V Longan Nanos:

No, I don't really have any plans for them...

I think I am going to buy a computer.

I hear they are all the rage these days. Dr. Clarke was a bit shortsighted though wasn't he. A CRT console that could talk to a mainframe? We had that in my high school in 1970! I love the 60s's look - groovy baby!
What, I need to say something else too?

Really?  We had ASR33s in 1977, except for the physics department who had a Hazeltine-2000 (Hazeltine was a local company; they probably donated it. (I worked there, summer 77!))  CRTs were very rare back then...

There was one in every television, so nor rare at all. I saw a (green screen) CRT on a very early mainframe (a calculator has more power than it did) in the early 60's.

When I took Fortran in the early '70s there may or may not have been a CRT on the mainframe,  I never really saw the inside of the computer room.  Just handed my stack of cards into the lady at the front desk and received my yards of printed output at the end of the day.

Ditto, although our computer centre had a big window in the corridor so you could see the Winchester drives and the line printer, which you could hear through the double glazed window.
Also had  a "mini computer" 6 foot high rack and a teletype machine beside it.
It ran BASIC, stored code on paper tape, you had to book to get to use it.
Wrote my AMSAT prediction code on it for my fellow local Amateur Radio operators in my part of the world.

We had a permanent TTY maintenance guy.
Despite the ink, oil, grease and paper fibres, he was, bizarrely, always immaculately suited and groomed.
I really don't know how he did it.

A pair of ICL-450s (IBM 360 equivalents) ran the entire CS department student load (apart from a handful of PDP8 and PDP11) the college's payroll and other agency work.

One had 128K, the other 256K.
Please don't PM technical questions - post them on the forum, then everyone benefits/suffers equally

Use to repair 33s AND 28s (marvellous high quality mechanical machines :) ), card punches (bloodletting devils) , card readers, line printers (100db) , mainframes (the air conditioning was great), oh the pain of it all !

The TTY 28s were eye opening:

I meant CRT terminals for computers.   Your TVs (mostly B&W, in 1970) didn't have video inputs, and a mainframe might have ONE display attached (the the famous SpaceWar display on the PDP/1 - 1963, and only $14k - $42k each!  Over 50 PDP/1s were sold!)

Wikipedia says:

The Datapoint 3300 from Computer Terminal Corporation was announced in 1967 and shipped in 1969, making it one of the earliest stand-alone display-based terminals.
I'm just not believing that CRT dial-in terminals trickled down to high schools by 1970.

Always been a side hobby but with limited finances this is currently all I can afford.
That said I hear a lot of good reports on them so now all I need to do is come up with some simple VHF antennas and a long wire for HF and convince the wife they are for something else  ;D

This is the one I got

It may not be the answer you were looking for but its the one I am giving based on either experience, educated guess, google (who would have thunk it ! ) or the fact that you gave nothing to go with in the first place so I used my wonky crystal ball.

How many "Hello, world" lines per yard?
