PROJECTS

Current and past projects I have undertaken.

RECENT NEWS (11/08/14):

Just added an ICOM 706 (not the MKII or the MKIIG) that I add after separating the control head from the radio and then added it to my ARES Go-Kit. Now I need to build the end-feed wire antenna tuner and finish interfacing the Raspberry PI for HF Digital and APRS on 2 Meters. Then the Go-Kit will be complete. The tool box I started with is nearly too small. Eventually will put all the radio equipment in a bigger tool box.

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.
