Bricoleur -- "Someone Who Fixes Stuff with Whatever he Finds Around"

A short time ago Paul VK3HN told us about the term bricolage. It seemed to capture much of the homebrew spirit.  This morning I heard Van Neistat's video-cast  (also something that came to me from Paul VK3HN) talking about the related term "bricoleur."  His  video (above) also has some great workshop ideas.  

Here is a nice Wikipedia discussion: https://en.wikipedia.org/wiki/Bricolage

Note from the Wikipedia page: 

• MacGyver is a television series in which the protagonist is the paragon of a bricoleur,^[28] creating solutions for the problem to be solved out of immediately available found objects.

Some Great Analog Pictures from MIT Building 20 and other Analog Locations

Here is a picture of Jim Williams taken through a Tektronix oscilloscope camera.  I never used one of these things, but Dean KK4DAS did.  Here are the details of the shot: 

I took this great photo of Jim Williams with a Tek scope camera sometime around 1977 or so. There was no digital (or analog) manipulation. It was a simple double exposure. I first shot a scope waveform, then just to see what would happen, I pulled the camera off the scope, stuck it Jim’s face and snapped another shot before pulling the film. I never expected it to look this good….a view from inside the oscilloscope!

Here is the collection of pictures that this 'scope shot came from:

Jim Williams -- Analog Man -- Book Review: "Analog Circuit Design -- Art, Science, and Personalities"

 

Jim Williams at his bench.  Note the mess. 

The Bob Pease book that KD4EBM gave me led me to the Jim Willams book entitled Analog Circuit Design -- Art, Science, and Personalities.  I'm only about a quarter of the way through it, but I can already tell that it is great.  Get this book.   Make room on your shelf.   

Jim was the editor, and it is a collection of contibutions made by a many different analog luminaries.  Curiously, none of the bios show that there are any hams among them (but the articles of many of them seem to hint at ham radio backgrounds).  MIT shows up a lot in the bios.  Jim notes in the very first line of the preface that "This is a weird book."   He talks about how it came together -- he met with the contributors and each of them pledged NOT to consult with the others about what they would write.  Jim notes that the result is "a somewhat discordant book," that "Hopefully would lend courage to someone seeking to do analog work." " The single greatest asset a designer has is self knowledge."  "Take what you like, cook it any way you want to, and leave the rest."  Indeed. 

I found that Jim's own contributions were among those that I liked the most. He writes about "analoggery" and "digital fakery"  but then acknowledges that this is a "good natured" controversy.  He notes that "no true home is complete without a lab" (a shack?) and that "no lab is complete without an HP series 200 oscillator."  His bio reveals that he lived in California with his family and "14 Tektronix oscilloscopes."   In a chapter entitled "Should Ohm's Law be Repealed?" Jim describes the very early influence of a neighbor, Dr. Stearn,  who owned a Tek 535.  It allowed them to see into circuits:  "You knew the excitement Leeuwenhoek felt when he looked in his microscope."  But that was not always enough:  Jim tells how Stearn once successfully troubleshot one of Jim circuits simply by running moistened fingers over circuit while watching the scope. 

Tom Hornak also really struck a chord with me. He writes of things that happened in the year "10 BT" (Before Transistors).  He talks about how he and a childhood friend had trouble understanding the differences between voltage and current.  "We found someone who knew the right answer, but he did not help us too much. Instead of using a simple analog such as a phasor diagram, he started to talk sine and cosine. We accused him of not knowing the answer either, and covering up his ignorance my muttering mumbo-jumbo."  Tom explaines:  "I know that trying to 'understand electricity' early in life had a lasting benefit to me. I got used to 'seeing electricity' in analogs and I am still seeing it that way. I believe every electronic circuit designer could benefit from thinking in analogs, and it is never too late to start. This belief made me write this chapter."  

Barrie Gilbert -- the man credited with inventing the Gilbert Cell (the heart of the NE602) -- has a chapter in the book.  He writes of circuits "laid out Manhattan-style" and "built on softwood bases." He hombrewed a very early TV receiver. He tested AF amplifiers "by placing a finger on the grid of the first tube."  (We recommended something similar with the SolderSmoke Direct Conversion Receiver, but some builders seemed not to believe that this would work!)    

It is undoubtedly a tragedy that we lost both Jim Willams and Bob Pease in June 2011. Jim died of a stroke at age 63; Bob died of a possible heart attack or stroke while driving home from Jim's memorial service. But here we are in 2025 still talking about their work and their books. In a certain sense they live on through their writing.  This is a lesson and an inspiration for those of us who sometimes get a bit down by the vagaries of AI and the algorithms:  We never know when -- perhaps long after we are gone -- someone might come across something we have written and find inspiration there.  

Three cheers for Jim and Bob.

SolderSmoke Direct Conversion Receiver Challenge -- Soldering!

The DCR challenge is going well, and we have several builders making good progress.  We noticed that some first-time builders are having a little trouble with soldering. Cold or weak solder joints are the bane of the of the homebrew builder’s existence.   It happens to all of us.  A board that was working fine suddenly is not working – you poke around and touch some part and the board springs to life – you just found a cold solder joint.  Dean, KK4DAS put together a short bonus video just on soldering.  He covers the tools you need for a basic soldering station, and step-by-step instructions for reliable soldering Manhattan Style.

Other Kinds of Workshops -- Making a Clock with a Lathe

Somehow, this video fits well with the SolderSmoke theme.  It may be that Uri cheerfully acknowledges that the lathe can kill you (the same is true of much of our gear).  Or it may be his repeated use of the term "Bob's your uncle" (has he been listening to SolderSmoke?).  Whatever the reason, this beautiful video fits here.  This is from Uri Tuchman's channel:  https://www.youtube.com/@urituchmanpigeon.  Uri is in Germany.  Thanks Uri! 

How to Organize a Small Shack

A YouTube comment from Paul VK3HN sent me back to "The Spirited Man" YouTube channel, and one of the first things I found was this video about how to organize a small space.  This is very relevant to my shacks in Virginia and in the Dominican Republic. 

Lots of good ideas here, but that propane heater kind of scared me.  And it seemed inconsistent with concerns behind the fire-preventing garbage can.  What do you folks think? 

Thanks Paul. 

 

Some Pictures of SolderSmoke Shack South

That's me at the operating position.   Window looks out to the terrace and to the ocean to the East, the  Mona channel.  The shack is on the top (seventh) floor. 

Here is the view from the terrace, looking South.  The big terrain feature is Cabo San Rafael. 

From the terrace looking North. 

Looking East into the morning sun 

From the terrace looking West. 

Antennas will go up there.  Perhaps solar panels too.  

A bog portion of the shack is a workbench with tools and test gear.  

Yesterday an old friend from Santo Domingo, Luis Ernesto HI8LEZ stopped by.  Thirty years ago we were pioneers in the use of amateur radio satellites from the Dominican Republic.  Luis Ernesto is in the book! 

ANOTHER Great Workshop

As I get ready to build the SolderSmoke Shack South, the Radio Gods (well at least YouTube) keep sending me these workshop videos.  Today's is also for a shop specializing in the repair of vintage audio gear, but the lessons-learned and observations are also applicable to a ham radio workshop.  This fellow's shop is in New York City, where space is very limited.  Check it out.  Lots of great ideas here.   

And check out the Novalux Stereophhonic channel:

Some Really Amazing Test Gear

Wow. Really great test gear, and an amazing parts collection.   This guy even gets a "nice workshop" comment from Mr. Carlson.   Pac1085 seems to be in Rochester N.Y. and he says he specializes in the repair of vintage audio gear.  He should have more subscribers.  Does anyone have more info on him?  

Here is his channel:  https://www.youtube.com/@pac1085/featured

Innovations and Inventions in Garages and Basements

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

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:
