HAM-gadget (6) – adjustment & enclosure

Posted on2021-11-132021-11-13

In this version I built in the possibility to adjust the summer and wintertime offset from UTC. It’s a very crude offset, I just add or subtract the offset from the UTC hour. Have to think of a better way to do this… Enclosure I built in the gadget in… Read the rest

HAM-gadget (5) – menu structure

Posted on2021-11-072021-11-08

This weekend I built in a menu structure into the HAM-gadget. Also I created a possibility to store and retrieve settings to the ATMEGA328P’s EEPROM, so they are saved for the next time you switch on the device. For now, you have to retrieve them manually, but that’s quicker then… Read the rest

HAM-gadget (3) – connected the GPS

Posted on2021-10-242021-10-24

Finally got it to work After much fiddling and trying out different libraries I finally had a bright moment and reverted back to the library that has been specifically made for this GPS module by Velleman… Duh… prototype, software version 0.5 That worked, also after some tweaking of the wires… Read the rest

Today I worked on version 0.1 of my new project. It’s in the prototype stage as you can see in the picture below. For this test it’s an Arduino Uno (clone by Velleman), two DS18B20 temperature sensors and two 20 x 4 displays. This version is for setting up the… Read the rest

Antenna preparation – masts and result

Posted on2021-05-152021-06-06

My son in law is a crane operator and he was kind enough te lend me a hand in erecting the masts for the antennas. First, we set up the big mast (a long piece of scaffolding pipe attached to two mounts that are bolted into the wall. Jig My… Read the rest

Antenna preparation – the antennas

Posted on2021-05-142021-05-16

After preparing the cables, next up are the antennas themselves. I have two at the moment: a Diamond Discone (25MHz – 1300 MHz) and a HyEndFed 3 band antenna (10, 20 and 40 meter). The coax plugs have to be weather proofed with vulcanizing tape. Diamond DisconeHyEndFed MK IIIPlug and… Read the rest

Today, my son in law brought me a piece of 7 meter (21 feet) scaffolding pipe. Together we mounted two brackets to the wall of the house. The brackets need to extend 0,5 meter to allow the mast to go past the gutter. Scaffolding pipe on the deck on top… Read the rest

Today I reinforced the wheelsets for my workbench. Two small pieces of 12mm plywood to make them a little more sturdy. Wheelsets reinforced Next and last will be a cross beam between the two wheelsets.… Read the rest

Workbench reinforcement

Posted on2019-11-08

This time I decided to reinforce the workbench before I put it on its feet (wheels). First I attached sheets of 12mm plywood to the back and the sides to prevent the parallelogram distortion that wrecked it last time. Back sideleft sideright side Next I will reinforce the wheel assemblies…… Read the rest
