Having switched to a solid state ham radio amp a year ago I haven't looked back on the days of having to pre-tune up an amplifier, however today on QRZ I saw on a for sale add by K2ZLS where he had Tuning enhancements for tube amplifiers he used some small color stickers (Avery® 5795 Round 1/4" Diameter Color Coding Labels, Assorted Colors) then when you tune up your amp on each band.. place the color corresponding on the band indicator and on the plate and load dials. easy quick tuning. For color blind just mark your red's and green's with a cross or something. Way cool Idea.. wish I would have done this.. stole his idea and blogged it to pass it on!
New features are added to the WebPower an Arduino-Webduino Relay Switcher!
The biggest improvement is that I have added physical controls for the real world. The first is a analog sensor for monitoring voltages or more specific light sensor to monitor the presence of a LED that is indicating a device is powered on... this is specifically important for devices that use pulsed relays. I have built in the functions for two such sensors and disabled them by default.
The next feature was the ability to control the on-off functions manually when your next to the device.. I wanted something that would power on the devices in order. So if there is a boot up sequence I could turn on my radio gear quickly with out the use of a webpage. Pressing the On button multiple times will turn on each relay in order, note that if you have a pulse relay the current version isn't monitoring for that and thus will latch a pulse relay. I will correct this later, or you can workaround by simply putting that relay as your last relay and being careful not to latch it.
The off button will reverse of the on button, something like a rocker switch would work nice for this..
I do recommend using a pull-down resistors well as remember to shield the use of analog pins, test this in your environment. I used 10kOhm pull-down resistors to keep the pins quiet. This was some dirty code I put in a lazy debounce and I'm sure there is a better way.. if you have input let me know!
You can get the code back on the main page for this project.

What better way to be a nerd dad then to purchase domain names for your whole family?
So that takes care of that!
Welcome to the world, Blog Molly, Molly Blog. Now who is who here?!
And the family photo, sprinkles with a rare "allow the boy to pet me" to be fair it was like 85F so the cat was too hot to move.
In a quest to operate my ham radio shack remotely, one thing I needed to accomplish was remote power for various devices. I have looked into multiple solutions however they are expensive and normally don't fit the bill just as I need them to. My requirements for this project..
1) Cheap, 2) Easy, 3) Flexible
I had a few spare Arduino's sitting around with a few EthernetPiggy boards. So thats the cheap part, priced out on ebay for $20 you can pick up the pair of boards from China, double check! Additionally I looked into some of the pre-made units. For example West Mountian Radios Rigrunner. Real nice unit, but the price is a little hot and with a limit of four ports and 40A on the DC circuit I am a bit limited in flexibility. Then you have the AC only version, the web power switch Also the most affordable way to go about it I have found. Same with the OpenSource Hardware ProjectWebPower Strip, however the quality manufactured version is highly preferred to this messy looking thing.
So back to the Arduino, I had it here in a junk box, I also had some 2-Channel Relay boards.. that are Optioisoloated real nice units. sitting in the junk box (more on why this is cool later)
After some toying around I came to the conclusion that the Webduino Library was the best for the situation, allowing POST and Auth with no effort from myself. About 30 hours of programming later, some help from jQuery.. I have a version 1.0!.
I found this old General Radio 1001-A Signal Generator at the Mike and Key Swap, got it for $10 bucks. With the idea of making Max a radio to play with. It turned out perfect. I made all the knobs potentiometers so that it makes the needle swing all over. And the switch turns on the red light. I have future plans to add a simple audio tone generator and use the dial to adjust the tone. Additional add-on features are actually hooking the microphone into a FRS radio so he has a base station to call mommy from!
With new HRD software came the decision to buy a new computer update from XP on the shack computer to windows8. It was quite a jump in technology laziness was the main factor but with a new PC the whole things was updated. First computer I purchased in 8 years. Its sweet. I actually like windows8 the "app store" is more like a crap store. But you dont need to use any "apps". Everything is working perfect I am even running my shack without a serial port (shock)
Intel i3-3.3 with 4500 video, 8GB ram, fancy hard disk, windows8, Rigblaster Advantage, IC756P3 (today) - point and click QSO!
Whew.. what a lot of work! after a lot of help and planning, the antenna project is done! Tower up Antenna up.. lets hope that's the last of it!
