Lecture and Lab, April 27th SolderFest! 10AM – 2PM

Lecture and Lab, April 27th, “Solderfest!”  Build a Borg LED Cube

This month’s L&L will be a “mixed bag” with several things going on at the same time. So the plan is a soldering exercise, continued DRAWS discussion for those who missed it in March with additional information on using AX.25 and some newly learned “tricks” involving interaction with the APRS system.

Remember, it’s more than just “position reporting” its a “radio network”!

We also have several unassembled Digital Volt Meters waiting for your expert soldering skills ($15 each). Also we’ve got what I guess I can describe as a “Borg Cube” LED display to build. I couldn’t turn down the price, which was $20 for each.

Unfortunately I could only order 5 as that’s all they had in stock. Anywho, it’s called a 3D Squared DIY Kit 8x8x8 LED Cube White LED Blue Light Board. I think it’s easier to simply call it the “Borg Cube”. I think this will be a challenging but rewarding project and something geeky enough, once completed, you’ll put on display in your shack (next to that Starship Enterprise model. Admit it ­ you have one somewhere in the house). I will say it comes with a 5v USB cable to plug into your computer. You may want to use a spare RPi power supply to power this baby.

Here is the video and instructions for the kit.  Note the recommended tools.

2019 DARC ARRL Field Day

Come join in the ARRL Field Day 2019 fun with the Dallas Amateur Radio Club. This is an open invitation – you don’t even need to have a HAM Radio license or call sign. The DARC will be operating from a new and exciting location – we will NOT be at Flag Pole Hill in Dallas. ARRL Field Day actually starts on the air activities at 1pm Saturday June 22, 2019 and runs until Sunday June 23, 2019. The Club will be operating as 3A during the entire time.

Our next club event will be a “catch-all” lecture and lab day on Saturday, April 27th. We’ll have digital multi-meters you can build (mine works great!), more discussion about APRS and the DRAWS digital workstation, and  a limited supply of “Borg Cube” LED cubes that you can assemble to practice your soldering. The topic for our May Lecture and Lab has also been announced: The Anderson Powerpole!

We have several contests in progress or about to take place this weekend: there’s the Yuri Gagarin International DX Contest, the ARRL Rookie Roundup, the famous Texas State Parks on the Air, and QSO parties in New Mexico, North Dakota, and Georgia. There’s also the European FT-8 Contest, if you know how to get WSJT-X to transmit your state.
