2 Computers, 1 Mouse/Keyboard!

I run two computers at my operating position in "studio A". Two keyboards and two mice really clutter up the table in front of the radio gear. I stumbled across a piece of free software that allows me to seamlessly slide my cursor from one screen to the other, and the keyboard input follows the mouse. You can copy things to the clipboard in one computer and paste it on the 2nd computer, and even drag single files from one box to the other (only one file at the time, with a 100meg file size limit)

The software was easy to install and ran without a hitch on my junk computers (one old XP Pro box, and an old Dell Optiplex 260 Win7 box). Now, one mouse and 1 mini-keyboard runs both computers at once, I love it! The software is called "Mouse Without Borders". The latest version is on Microsoft and doesn't support XP. I found an older version that does support XP over on cnet. Oh, it'll run up to 4 computers at the same time, too.

I ran multiple monitors on a single computer about 10 years or so ago with a graphics card and some software. In my situation, I'm running multiple 15+ year old boxes at home to share the load, so it looks to be a good answer to my problem. I could buy something new and much faster that would do everything, but I'm a tightwad and am always looking ways to keep old stuff working. It's neat to not to toggle between screens on my primary applications, and everything is fast by each computer running with less overhead. 

Here's a link to the new version for Win7 and newer:

Blast from the past...

A cool snippet of an advertisement from 1940, and this tube is still in operation at many ham stations! I love these old promotional bits.

I miss the Radio Shack Project Boxes...

Wow...sure miss the days when Radio Shacks were all around, and I could grab one of these cool cabinets to build things in. I've built a ton of stuff in these things...keyers, receive preamps, T/R Switches, Power Supplies, Amps, you name it! Lots of stuff, I wish these were still available.... 

 Later, before Radio Shack closed up, these cheapie plastic boxes came out. They're cool for stuff, but nothing like those nice metal cabinets with the wrinkle finish. I wonder if anyone still sells the metal cabinets above?? Here's a few pics of the plastic stuff I also built things in...

Oh well, I guess times change, but I still like to live in the past!! Email me if you know of a source fo rthe metal cabinets in the first picture group. Thanks!

A Few Bits From JARSfest...

I headed up to a hamfest put on by the Johnston Amateur Radio Society (JARS) on Sunday 11/18/18. We had a chilly start for the tailgate area, but it warmed up quickly. BIG turnout! There was loads of stuff outdoors by the tailgating crowd, and all tables were sold out inside. Here's a few pics I took...

You can tell by the photos above, that I like the vintage stuff :-)  I picked up two bags full of components for various projects, only spent abt $30! Shrink tube for trap caps, piles of capacitors (HV, ceramics, electrolytics, etc), zener diodes, transistors, switches, project boxes, a huge RF plate choke, rubber feet, spacers, nicad battery packs, binding posts, etc.

 

 I saw lots of old friends I had not seen in years, met several new friends, got to look at tons of stuff, and had the most fun I've had at a hamfest in years.

"Sealed" Lighting Repairs...

OK, this isn't ham radio related, but it is electrical :-) On a recent fishing trip with our little JonBoat, Debbie spotted the rear driver's side tail lamp module on our boat trailer had failed. These are sealed incandescent units, without any possible access to replace the lamp. They're not very expensive, but being the tightwad that I am, I had to set about to attempt a repair. 

These have a dual filament 1157 lamp inside, with the wiring soldered to the bulb, the bulb mounted in a glob of silicon rubber adhesive, and the red lens literally glued in place. Using my Dremel tool and a carbide cutoff disc, I cut around the junction where the red lens was attached to the white plastic housing. 

With the red lens removed, I scraped off the melted plastic, pulled the lamp out, and peeled the old silicone adhesive out. A new 1157 lamp (costing about a buck!) was re-soldered to the wiring, a new glob of silicone adhesive (bathtub caulking) was squirted into the middle of the white plastic base, and the new lamp was nestled down into the adhesive. Once that cured, I applied a thick bead of silicone caulking around the perimeter of the lens, and the lens was pressed back into place onto the base. The excess caulking was wiped off, and the assembly was allowed to cure.

Once cured, the light assembly was reconnected to the trailer wiring harness, and the light assembly snapped back into the gasket of the trailer. A quick test showed all to be well. Gotta love a cheap repair!
