Innovations and Inventions in Garages and Basements

The Hewlett-Packard garage

There is a lot of inspirational stuff in this blog post, especially for those of us who work in home workshops, often in garages or basements. 


Thanks to HackaDay for alerting us to this.

Pine Boards, Analog VFOs, and Homebrew BITX Transceivers -- AG5VG's Magnificent Creations

Click in image for a better view

This is amazingly cool.  WE ARE NOT ALONE!  There are others out there breaking the tyranny of the Si5351, building BITXs with analog LC VFOs.  And using copper clad boards affixed to pine boards. Plywood cabinetry!  And medicine bottle coil forms.  Really great.  And what a wonderful workshop. Thanks Michael.     

Good Afternoon Bill,


This is Michael Sahn, AG5VG.

I hope your doing well, all is well here in south Texas. I have recently built a bitx20 receiver and bitx20 for 40 meters receiver.

I built it using the analog VFO and both of mine are stable. What an awesome feeling it is to have a stable homebrew VFO. I have attached pictures .

It’s been a fun journey to get to this step. I have just been enjoying the receiver as Farhan instructed us. Then I’m going to go through the transmit side.

Air core coils are great for VFO. On my bitx40 I used a medicine bottle bottom but I put the VFO in a tin can as you will see in the pictures.

The bitx20 is all out, hand capacitance is a slight issue but it’s all learning experience.
Going to be adjusting the pvc coil bandpass filter inductors, I think the value is a bit off so it’s not as loud as it should be, but everything else is set good.

Just wanted to check in and great job on the videos and podcasts. I really enjoy them

73s
Michael

K0IYE's Thoughts on Homebrewing and Workshops

Click on the image for a clearer look

I like Frank Harris K0IYE's book so much that I don't mind posting about it frequently.   "From Crystal Sets to Sideband" is must-read material for all homebrewers.  

The picture above is especially significant.  I first came across it in the old pulp-style magazine called World Radio.  The picture, like Frank's book, is truly inspiring.  

This week I stumbled across a relatively new chapter in Frank's book.  Chapter 3A deals with his approach to homebrewing (Luddite, analog, HDR) and his advice on how to set up a home ham-radio workshop.  There is a lot of wisdom in this chapter.  

The opening paragraph of Chapter 3A really grabbed me.  Check it out here.  Click on the text below for a better view: 

Click on the image above for an easier read

Frank's advice on what to do when you get stuck on a problem is right on the mark, and a bit counterintuitive, but very true: Do something else for a while. 

Click  here for all of Chapter 3A:

Chapter 3B also looks great. 

And click here for the entire book (including a Spanish translation!) 

Thank you Frank for sharing with us all of this wisdom.  73 OM

Andreas HB9BLA's Ideas on Building a Lab or Workshop

Lots of great ideas on workshop or lab design from Andreas, the guy with the Swiss accent.  Andreas is HB9BLA.  I liked all of this, especially his idea on books.   

A while back Andreas was interviewed by Eric Guth on QSO today: https://www.qsotoday.com/podcasts/hb9bla

Thank you Andreas!

Mr. Carlson's New Lab and Workbench


I am very glad to see that Mr. Carlson is NOT slowing down.  In fact he has built another lab and is ramping up.  FB!

How to Tap an Aluminum Heat Sink: Pete Juliano Shares Tribal Knowledge


This is a SolderSmoke Classic:  Pete Juliano N6QW coached me on how to tap (put screw threads)
a piece of aluminum.  This is an important homebrew skill that -- as I demonstrate -- is 
easy to screw up (no pun intended).  Thanks to Pete for sharing this tribal knowledge. 

This video has been quite popular.  It has been viewed more than 33,000 times since 2014, and there are 35 comments attached to it.  

Thanks Pete!

The Workshop and Bench of the QRP Home Builder, Todd VE7BPO


What a treat!  We have been learning so much, for so long from Todd VE7BPO.  I was really pleased to have this look at the workshop where all the magic happens.  

While my technical abilities are far inferior to his, I was pleased to see some scenes and some shelves that are similar to those that can be found here. 

Thanks Todd!

Workbench and Workshop Tips -- Please Put Suggestions in the Comments

During a recent visit to Barnes and Noble I picked up Adam Savage's book (please use the Amazon link in the righthand column) about Making and workshops.  Adam's book reminded me of the importance of giving thought to the organization and set-up of your workbench or workshop.  I found more tips on YouTube: 

Wow,  watch the KatVoltage video (above).  Unlike the person in a recent unfortunate advertisement, Kat clearly knows which end of the soldering iron to grab.   She is setting up a good workshop -- you can tell from how she is organizing the bench.   I wish her a lot of luck. htt(s://www.youtube.com/watch?v=1NcVzTu7TbE&t=54s

Andreas (the guy with the white glove and the Swiss accent) has some good ideas:https://www.youtube.com/watch?v=inW57njiq1A

The EEVblog guy has a good guide to the basic stuff that you need to build an electronics workshop.  It is a bit dated (2011) but the guidance is still very good (I wouldn't go with the homebrew or kit-built power supplies): https://www.youtube.com/watch?v=R_PbjbRaO2E 

Van Neistat has a very good Top Ten List of things NOT TO DO in a workshop. NO FLATHEAD SCREWS.  I'm with you Van.  NO HOARDING.  etc. https://www.youtube.com/watch?v=3bAZQ9nWybM&ab_channel=VanNeistat  Paul VK3HN suggests we develop a similar list for ham radio homebrewers.  Please put your suggestions in the comment section below.

Building a Workshop (or a Shack) in a Crawl Space


At first, this video made me think of Michael AA1TJ and his underground Hobbit Hole workshop.  Then I started thinking about my own crawlspace -- it looks remarkably similar to the one in this video.  Hmmm...  But no, I think I will stay above ground. 

One thing that would DEFINITLY not work for us would be the flooring that kind of eats small parts that get dropped.  I would all soon have large numbers of small parts under those mats.  This would drive me nuts.  

But lots of good ideas from Australia in this video.

Flip-up Workbench Build -- Possible Application for Our Test Gear


Interesting workbench build.   While his tools were all for woodworking, this got me wondering about using this technique to store bigger pieces of electronic test gear that are not in use every day.

QRP Labs HQ Tour


Really cool to see Hans describe his QRP Labs workshop in Turkey.  Lots of soul in that worshop.  Thanks Hans.  

 And here is a 2022 Turkish media interview with Hans and his team in the workshop:

The Amazing Workshop and Test Gear of Tony Albus PE1ONS


This is almost too much.  This makes me want to go out and buy some more test gear, maybe another scope, or a spectrum analyzer, or at least another DMM.  I mean Tony has at least three of everything. 

This is really amazing.  Tony is obviously a test gear guy, but he also has a ham call PE1ONS.  He says he is not too active, but we should encourage him to get more involved with ham gear.  We need guys like him working on ham gear.  And he seems like such a happy person.  

Here is his QRZ.com page: https://www.qrz.com/db/PE1ONS

Here is his awesome YouTube channel: https://www.youtube.com/TonyAlbus

Tim Hunkin on Prototyping, Welding, and on Being a "Jack of all Trades"


I always like Tim Hunkin's videos, even when they are not directly related to radio electronics.  In this one we learn about his prototyping techniques -- this does seem similar to what many of us do when building rigs.  

I liked his explanation of welding, and of the dangers of the angle grinder (his precautions on this device were similar to those in a recent video by "Spirited Man" Van Neistat). 

Tim's final comment on how in the modern world we seem to have moved away from the notion of having one person skilled in many different areas -- we are now very specialized, so the "Jack of All Trades" is increasingly rare.   That's a shame.  Oh well, we can be Jacks of all Trades in our radio shacks. 

Thanks Tim!

Soldering School -- 1958 (Video)


I went to a similar course at Ft. Gordon Ga. in 1977.  But I think my instructors would pass out if they saw the way I REALLY solder in the shack today.  But hey, I am building SSB transceivers, not spacecraft.  If one of my joints is bad (they rarely are), I can fix it.  So chill out Mr. Instructor -- if we were to do every connection your way it would take us a lot longer to build a rig.

Why Does Solder Smoke Always Go Right Into Your Face? Now We Know


Because our podcast and blog is called SolderSmoke, I felt compelled to post about this video in which a fellow does some pretty interesting research into how solder smoke actually moves.  We don't often see this much concern about the behavior of our beloved smoke. 

Thanks to Todd K7TFC for alerting us to this.  

I use a small fan to disturb the airflow pattern.

Making a BIG Transformer from Scratch -- Video


Wow.  Watch this young guy make something very useful.  This video reminded me of the 16 de Marzo neighborhood in Santo Domingo, where I was able to get the RF choke and power transformer of my Hallicrafters HT-37 repaired.   This guy takes that a big step further.  He does lot with very limited resources, and does it in a workshop that many of us just wouldn't be able to tolerate. There is obviously a lot of skill in his production of this transformer,  and lot of wise re-purposing of materials.  

I think this shop is in Pakistan.  Three cheers for the Malik Transformer makers! 

Thanks to Rogier PA1ZZ for alerting me to this video.
