Gosh.

All go.

Esteemed customers as dense as ever.

Just had the shorted out resistor on the breadboard syndrome yet again.

Not to mention the guy who bought a matrix 4 x 3 keypad on ebay & couldn't figure out what the matrix was.

but it simulates ok on Proteus

I almost feel the urge to do zeity's course, just so I can understand his ramblings.

It would cost a lot of money to be bored....

This is the keypad that's causing difficulties:

It must be said that the matrix arrangement for the keys is less than intuitive.

This is a breadboard.

This breadboard is transparent.

You can see the connections inside the breadboard.

By the time you get to the third year, you shouldn't need to use a transparent breadboard.

To make it even more obvious, there's a picture like this one

stuck on the fecking wall.

And this image is stuck on the fecking wall too:

Along with this for the hard of thinking:

Not to be confused with:

which won't work too well with electronicky stuff.

The assembled congregation will be pleased to know that the keypad problem has been rectified.

Apparently entering a code now does sommat.

The first time the twins played with a breadboard they were 7. The next time they will play with one is in 2 weeks when I end up buying more at maker faire

I will report back if they grasp the basics again

I am endlessly unsurprised by how little the esteemed customers retain.

Though you might expect that, after nearly 3 years, they'd have twigged how a breadboard works.

It has been suggested that it should be a practical test before they're allowed on the course.

Except we'd have just about no customers in that case.

There was an article in New Scientist some time ago about how we assume that others have the same knowledge as ourselves.

I'm long passed that.
