Ultimate software is up to date

As I have mentioned several times on this blog, I have thoroughly enjoyed WSPR modes ever since Hans, G0UPL came out with the first Ultimate QRSS/WSPR kit.

That means that I have three different versions of the kit. Since Hans has kept on updating the software and even published the compiled versions, it is also possible to upgrade even the old ones.

I have done that and the displays here show the Ultimate 3, the Ultimate 2, and the Ultimate 1 with the latest software.

It is possible to upgrade the chips in-circuit, but I found that it is simpler to remove the chip temporarily from the socket and move it to a simple veroboard with crystal oscillator components. It is connected to my Ebay version of the USBtinyISP.

Altoids Projects

I like to build small electronics projects and like many others I have found the small Altoids tins to be excellent enclosures. 

These tins are inexpensive, well shielded, easy to work with, and least but not least they enable you to make experimental circuits that are sturdy enough that they can be reused later.

Pictured here is a collection of projects I have built over the years with the hope that  they may inspire others.

Keyer-in-a-mouse

I use the K1EL K10+ chip as a morse trainer. The chip has more features built-in than I'll ever get use for.

The keyer is built into an old three button mouse. The center button is the command key and the two others are the paddles. The keyer mouse is completely self-contained: It has a 3 Volt battery, and a piezo speaker located under the mouse in the hole where the mouse ball used to be.

However, normally I connect a paddle and often also a set of headphones.
