Current and past projects I have undertaken.

Home built Panadapter using a Raspberry PI and a
5″ TouchScreen

January 2018:  I am also building slowly a Raspberry PI based Panadapter based upon the April 2014 QST article written by Martin Ewing AA6E.   The link to his website for the project is

I will use this home built Panadapter with my Elecraft KX3 in my ARES Go-Kit  I am having to learn the Raspberry PI all over again.  Just for fun, I will try to see if I can use the Beaglebone Black for this Panadapter as well, being I have two of them on hand.  I had even thought of trying the Raspberry Pi Zero to see if it can handle it.

Update 1/07/18:  Just got Ubuntu Linux for the Raspberry PI installed after finding my only 8 GB micro SD card I had on hand.  Raspbian Linux will only fit onto a 16 GB as just the OS takes about 7 GB.  No room for files or swap space.


Interfacing an ARCOM RC210 Controller to a Vertex Standard VXR-7000 Repeater

December 2017:  I have just finished the interface cables in interfacing the ARCOM RC210 controller to the Vertex Standard VXR-7000 that belongs to the Lake Wales Radio Amateurs radio for the 147.330 MHz K4LKW Repeater.  Now I have to finish the programming on the ARCOM controller and final audio adjustment to the repeater and link radio.


Re-Construction of a small 12 Volt 3 Amp Power Supply for my ARES Go-Kit.

July 2017:  I have just completed the re-construction of an old 12 Volt regulated power supply that I had in my junk box to charge the battery in my ARES Go-Kit.  This power supply originally had an old style voltage regulator and had a 110V 2 prong cord wired directly into the enclosure.  I installed a CEE type 120V power jack used in computer power supplies (as I do not like project enclsoures with cables dangling out of them) and Anderson PowerPoles for 12 VDC Output.  I also mounted an LM350K voltage regulator on the outside of the case for better heat ventilation.  olts of power to my ARES Go-Kit to charge the internal battery.  I goofed up a little bit on using an air metal nibbling tool to cut out the metal cover away from the voltage regulator case which is not at ground but is connected to unregulated voltage in.   Other than that it serves the purpose very well.

Raspberry PI and ARM Development Station

May 2017:  I just completed the final construction on my new Raspberry PI and ARM development station.  I wanted to have a development station for doing new ARM microcontroller based project, including the Raspberry PI.  Power supplies are built into the box just like my other development stations.


Arduino Development Station

April 2017:  It was complicated to do the wiring but I have just completed my new Arduino platform development with common shields laid out side by side instead of stacked one on top of the other.  That way I could see better what was going on in development.  Power supplies are built into the box just like my other developments stations.

Re-Construction of my ARES Go-KIT.  Emphasis on lower power transmitters.

12/31/2016:  I just completed the reconstruction of my ARES Go-Kit with a Elecraft KX3 for HF and a Jetstream JT-270M dual band radio for VHF and UHF.  It has the battery charging controller and battery built right into the box.  Because both radios only have transmitter power outputs of 10 Watts each, the 12V 9AH battery should be capable of carrying the radios for a while.  Need to take updated picture since I added a bit more foam.  I put Anderson Power Poles on the outside of the box so the battery can be charged and or the radios operated from an external charger or a solar panel.

Construction of Battery Box for Portable Communications Stations

7/26/14: Completed more work on my portable communications station. Finished the power supply box (which includes a 12V/10A Power Supply, isolation circuitry, and two 12V 6AH gel cells wired in parallel. Finishing wiring an adapter for a Kenwood MC50 desk microphone to use with the VHF/UHF voice communications radio (Yaesu FT-5100R), and completed construction today on a portable antenna support structure, which I refer to as a “Quadpod”. Pictures of the radio box, the new power supply box, and the portable antenna mounting system.

Identification and Timeout Timer

10/06/13 – I have recently designed and built a PICAXE microcontroller based timer to remind a ham radio operator when it is time to identify their station or that they are about to timeout the repeater. The timer by default is a 3 minute timer or can be se to be a 10 minute timer. Will have a project page for it shortly.

The timer is based upon a PICAXE 08M2 microcontroller which is a PIC12F609 with the PICBASIC interpreter pre loaded on the PIC Microcontroller. I received the inspiration from this project after Geoff N1GY published a 555 based timer in Issue 200 of THE EXPERIMENTER

Bad Capacitors Replacement on a 32″TV

8/24/13 – Just completed repair of my 32 inch TV that was given to me by a friend after it manifest the problem of being difficult to turn on. The problem: Seven defective electrolytic capacitors. Click on link above to read the rest of the story.

Portable Communications Stataion

4/12/13 – I have recently designed and partially built a Portable Communications Station into a plastic toolbox. The power supply and battery are in a two drawer plastic bin. Work on that part is yet to be completed. The station includes: (1) Anderson Power Pole distribution panel, (2) Yaesu FT-5100R for 2 Meter and 70 Centimeter voice communications, (3) Yaesu VX5r, A TNC PI, and a Raspberry PI for APRS, and (4) 12V to 5V regulator to provide power to the Raspberry PI, the TNC PI. Also included is a small 7″ DVD player, which does not play DVD’s anymore but the monitor still works great and is powered by 12VDC. Still have a few minor details to take care of in the radio compartment.

PIC/PICAXE Development Console

I have been studying for the past 2 years all about microcontrollers and getting “Tooled Up” to do work with microcontrollers. I have always wanted to get into working with microcontrollers since going to electronics school in 1989. Now it is coming close to fruition. I am building an PIC/PICAXE Development Console that will allow me to test and development projects using either the lower end 8 Bit PIC Microcontrollers or the PICAXE Microcontrollers which use the a PIC Microcontroller with a preloaded BASIC programming style interperter.

I will have a full article for this project for you to view soon. Stay tuned!

Complete Buildout of my Amateur Radio Base Station

After several years of putting it off, I finally this summer did the rebuilt and expansion of my amateur radio base station at home. Currently I have capabililty on 40 Meters, 2 Meter FM, 70 Centimeter FM, and soon coming 2 Meters on APRS. Will post updated pictures as I plan on adding a few more radios.


Complete Buildout of Workstations in Workshop

I am very close to finishing the final details of the new workbench positions in my workshop. The picture on the left is the microcontroller breadboarding and development workbench, which also doubles as a PC Repair workbench. The picture on the right is the anti-static workstation used for circuit construction and soldering. It is covered with sheet aluminum and is connected to a good grouding system to mitigate any static electricity build up, the enemy of small integrated circuits.
