    Great coverage of commonly-used techniques - showing how practical circuits were built is very educational for new builders. Also, having seen Dave AA7EE's circuits in person, I agree: he is an artist! I hope to someday match his patience and forethought in building.

    In a pinch, I have used 1/32" RC airplane plywood as "circuit board" and as "islands" and used combinations of the methods you show. Also, various widths of the adhesive backed copper foil tapes used in stained glass work can be employed in lots of creative ways. Great video!

  • @freon500
    @freon500 11 років тому

    Thank you W2aew, you are a master at this. For those of us who have a drill press, time and interest, as you pointed out, we can make any number of circle cutting bits that cut to any depth, from scoring on to complete perforation, by serration of the end of various diameter steel tubes as Davies by the Sea points out, I think he used a tubular bearing out of an old video cassette. A diamond cutting tool is far superior in this application, of course, because the fiberglass in pcb dulls any plain steel tubular bit very quickly. Still, in a pinch one will improvise with whatever one has at hand.

    Nice vid!
    I've been tinkering off and on with electronics since the 70s (the 60s if you count taking stuff apart without it ever working again!) and I just learned about Manhattan style circuit construction yesterday! It blew my mind! Of course I'd done point to point, and I'd seen the Dead Bug trick without knowing there was a name for it, but I had never seen the island style. Whether it be the raised islands of separate board layers or the mechanically traced circles, the whole thing is a revelation to me.

    I built a small copper clad board when I worked for IBM in the late 80s that used an HP step recovery diode that was used in a TDR in a high end HP oscilloscope (HP54120T) (the diode could only be bought by those who owned the scope and so may have needed it for repair) and the board could generate a 50 ps pulse with an amplitude of 5 volts. Needless to say it needed to have a very strict 50 ohm impedance throughout with minimal impedance discontinuities. It used rigid coax and sma connectors.

    ~4 years later, and it's still a great video. Thanks.
    Something to mention, that may or may not have been prevalent when you made this video, that I just discovered recently is that you can get professional PCB with your design done VERY cheap these days. I won't point to a specific one so that it doesn't look like I'm plugging anything, but $2 or so will get you ~5 boards in the 10cm x 10cm single sided range and some of the more popular pcb design applications spit out exactly what they need to build them. Of course the methods that you show here are still great at-hand solutions when an idea hits you or when you want to test something. Just wanted to put it out here for anyone else who may not be aware. I was actually researching small CNC machines when I discovered how cheap it has gotten to have them done professionally.

    Love the dead-bug construction. I'm pretty new to electronics and have done it with a dremel before, but cutting out those little islands with a hole-saw is a great idea! There's likely to be a very similar and far more affordable diamond impregnated hole-saw in your local hardware or tool store though. They'll be in with the masonry bits, because they're intended for tiles.

  • @AlexeiPolkhanov
    @AlexeiPolkhanov 11 років тому +6

    Thanks! Very nice video. I found that these prototyping methods work fine up to 200MHz with some care. When I wanted to prototype circuit at 900MHz and 2.4GHz I had to try something else - I started with gluing self adhesive copper foil to single sided FR4 or PTFE board substrate like Rogers 3004. It works pretty good and reworking/adjusting microstrip components with foil is easy too. I am nowhere an expert in using this method so I am wondering if anyone else tried it? How do you prototype something at 2GHz+?

    • @w2aew
      @w2aew  11 років тому

      Your techniques for UHF and microwave prototyping are good. Especially at 1-2GHz and above, controlled impedance traces, impedance matching, etc. are very important, as well as the use off low loss substrates.

  • @keithostertag
    @keithostertag 11 років тому

    Thanks Alan. For a future video, could you discuss considerations when-to-use and when-not-to-use sockets for components? I sometimes worry about directly soldering component leads due to heating, but of course the socket introduces problems like parasitics and intermittent connections, etc. Some IC's are so cheap it doesn't matter, but I don't want to ruin, say, an AD8307 or other fairly expensive IC while soldering it. Also sockets help if you want to exchange different types of components later.

    • @w2aew
      @w2aew  11 років тому

      You really covered most of it in your comment! If you have a good soldering iron, and are proficient (meaning that you don't have to apply the iron for an excessive period of time), it is unlikely that you'll damage a part. If you think that there might be a reason to re-work, modify, change the design, then a socket is a good idea so that the part isn't exposed to a lot of re-heating. Of course, if is a part you want to re-use, or maybe change to a different part as an experiment, then a socket is a good idea. If you need the highest speed, fastest risetime, etc., then avoid the socket if you can.

    Hi, does wiring them all up direct like that not get extremely finicky? With the proto board with holes in? With wires overlapping each other and so much solder? It looks like hell to be honest!
    Printing and etching has to be easier?
    I love the little PCB island bits though.

    • @w2aew
      @w2aew  10 років тому +1

      Each technique has its advantages and disadvantages. There's really nothing finicky about direct wiring. In fact, you can often create higher performance circuits this way by having better control over parasitics. Beauty is in the eye of the beholder - to me, these hand-built prototypes are beautiful.

    • @w2aew
      @w2aew  11 років тому

      You can. It will help a little to lower the ground impedance. This will also increase the capacitance of every node to ground (which usually is a bad thing, but can be advantageous in some circuits). Of course, this won't help reduce the inductance if the interconnects.

      but would like to do it with the Manhattan technique. I'm not sure if the big ground plane will affect sound quality because of capacitance.

    Do you have any links to info on things like wrapping wire around those ferrite cores, for the purpose of making chokes and maybe even a few little audio isolation transformers? I’m sure a quick search would yield some online tables for sources of this sort of math. Perhaps in your previous endeavors you have encountered some free software, or an online applet which are of particular interest to you? Edit: I can see that you yourself have a great wealth of very helpful videos, +1 subscriber. I REALLY APPRECIATE YOUR STYLE!! You have a very interesting aesthetic, and I’m glad I didn’t just cut off your video because you really have a lot of great work for me to even brag to other people about!! THANKS FOR SHARING!

      There are online calculators for determining the number of turns, etc. One easy one is Toroids.info

    Cutting islands into copper. I've never tried, but you can buy ten different sizes of diamond cutters on Amazon. Sounds way better than grinding a drill bit. And cheaper too probably.

    A dremel and a small engraving bit also works well for making circuit boards if it's simple enough that you don't need to etch it.

    Hey, please show how to solder copper clad, because my iron just cannot put solder on the copper clad. Also the copper clad gets dirty, how to clean it? Thx in advance

    • @w2aew
      @w2aew  6 років тому

      The copper must be clean before you can solder to it. It can be cleaned using steel wool or a "scotch brite" pad, or even some 600 grit sandpaper. You'll need an iron that can provide enough heat - best to use a temperature controlled iron.

    • @w2aew
      @w2aew  6 років тому

      Yes, but it is usually included in the solder (rosin core). No harm is using more though.

    • @HalfLife2Beta
      @HalfLife2Beta 6 років тому

      I bought 600 grit sandpaper and sanded the surface, but sadly i touched the copper before with my fingers. Can sandpaper remove fingerprint marks (i suppose its grease) or should I use some kind of acid like vinegar and salt ? I will now take latex gloves when manipulating copper clad. Thanks in advance.
