Logitech K780 Keyboard

K780 and M720

Just received and installed my newest keyboard. A Logitech (of course) (most are pretty good). Model K780

This keyboard is wireless. That is the main attraction for me. Next it is able to connect to multiple devices (3 to be exact). The best part of that, the connection can be either Bluetooth or USB 2.4GHz dongle. The best part of THAT… is it can be any combination or all of either.

Most Logitech multiple connect keyboards can only connect to one USB dongle and the other connections must be Bluetooth. In my opinion, this is the only keyboard they built to my expectations.

CRAY Super Computer

I have been kidding myself and any readers here. Not much but a little. SBC (Single Board Computers) are not going to replace a fully loaded desktop or laptop computer anytime soon. If I have left that impression it was only because of my excitement on how well recent edition SBCs perform.

What is missing from the SBC is lots of high speed RAM and its necessary sidekick, high speed NVM (non volatile memory)

I built up an Intel NUC computer a year ago with a core I7 7th generation processor, 512GB Solid State boot drive, Two GB […] Continue reading » Just Kidding – Accepting Reality

A Pie Eater?

When operating, a heat sink (not show) must be applied to the processor.

A friend of mine, Mike S. in Michigan, USA has sent me a new SBC (Single Board Computer) with which to play. It is a super-set clone of the Rapberry Pi (RPi) design. The board layout, size and basic design are equal. But it has much more of everything else.

The SBC is called the Asus Tinker Board S. I will refer to it as the ATB-S. Sometimes just leave off the Asus A (TB-S).

The technical specifications are impressive.

The processor High speed operates at 1.8GHz rather than […] Continue reading » A Pie Eater?

Raspberry Pi Printer

Raspberry Pi Printer

I was telling myself I had a pretty good mini PC (computer) in the form of a Raspberry Pi (RPi). It was capable of doing everything I thought a small computer should do. But then, it hit me. Not the computer but a realization.

There was no way for me to send any of my documents from the RPi to a printer. There is no printer set-up in a stock Raspberry Pi. Nothing in the configuration and nothing in the user menu. Well That’s Fine (WTF).

So, I do some web searching to see what others (other folk) are doing. Not too well it seems. Some Noob […] Continue reading » Raspberry Pi Printer

It’s Under Control

It’s Under Control

The Raspberry Pi 3B+ is holding its own as a low cost PC style computer. It is proving practical as an everyday driver (in automobile terms) and of course can be customized to the Nth degree for just about any special embedded control application that can be imagined.

It certainly is not a screamingly fast super computer. That is not its design or purpose. That means there are some practical performance limitations. Nothing that is a show stopper or spoils the ride.

It is in every sense, a “real” computer as we have come to expect. It is also much more than […] Continue reading » It’s Under Control
