Buzz_salutes_the_U.S._FlagI hope you come out and see us at Moon Day! We’re all here, and we’ll probably need some extra help this afternoon after 14:00 local, if you can make it.

Our next Lecture and Lab will focus on a DIY Mini UPS suitable for use with a Raspberry Pi or charging your phone. It has 5v and 12v outputs and uses only 1 18650 Battery.  The kit from the link above will be $10.  Bring your Soldering iron, hot glue gun, clippers and screwdriver.  If you don’t have any of the above, we will have extra on site.

The contest calendar is pretty quiet, but this is the season for sporadic-E and for the CW WW VHF Contest.

Moon Day is a great opportunity to get young people interested in amateur radio and science, so please save the date. More details about how to volunteer for the DARC and AMSAT will be coming soon.

The contest calendar is quiet…everyone must be recovering from the Fourth of July. Don’t forget to send away for your 13 Colonies certificate. You don’t need a clean sweep—and it’s how they support the event.

July Meeting Program: Share Your Money-Saving Tips!

DSC_3572_cropNext meeting’s program will be “Tips and Tricks for Frugal Ham Radio,” presented by me—Tony Mendina, NT5TM. I’ll share my favorite techniques for ham radio on a budget, like building my own antennas and even test equipment…but your participation will be important! There’s only so much that I know, and you probably know lots that I don’t. Do you assemble your own cables? What tools have saved you a trip to the repair shop? What non-ham things have you substituted for expensive ham gear? Please bring your stories, tips, and even show-and-tell items to the meeting. We’ll all be glad you did.

Updates: Bill, N5BB, and several other folks recommended this great collection of ham and electronic training videos by W2AEW.

Participants also mentioned the free practice exams at https://hamexam.org/. It’s important to get the URL right—put a .com on the end and you go to a commercial site.

And David, W5EBB, mentioned a site full of antenna schematics in the comments below.

And if you need to zoom in on that picture of Bill’s power supply, the full presentation is here, too. Frugal Ham Radio Tips and Tricks

Usually I don’t post links for the Geek Net, but I’m pretty sleepy from Field Day…I might miss something. So, here are some items I might be mentioning during the net! If you have anything you’d like to add, please contact the club or just post a comment for this post.

If you’ve seen a beautiful freezing soap bubble video, here’s the story behind it.

The latest news about methane on Mars is interesting, but not exciting…yet.

The first-ever night launch of a Falcon Heavy is coming up tonight sometime at or after 10:30 pm. There will be lots of payloads on this one, including the remains of 152 dead people and a very interesting atomic clock.

Updates: Calvin, W7KYG, reports that the Raspberry Pi 4 is now out!
