Haha, I too have made vertical tower of integrated circuits. I enjoy freeform soldering, and have made some stacks of shift registers, If you search Dead Bug Prototyping and Freeform Electronics, you should find my instructable that includes my vertical shift stacks
Now the Vocoder is near test, will you revisit this one please?
May be this comment goes too late: I use this fast optocoupler: HCPL 0601-500E. There are various models…
Not cheap but very, very fast…..
I hate getting electronics wrapped in bubble wrap. Especially if they only come in ziplock bags, rather than proper ESD protective packaging. I got som 74HC181 4 bit ALUs in the mail the other day from Ali Express that were wrapped in bubble wrap and despite it being a very humid day, I could hear and feel the static as I unwrapped them. I haven't used any yet to test for damage, but I intend to scold the seller.
Julian, I haven't watched this video yet, but when I saw the title snapshot, I thought you may be doing a test on how well the so-called anti-static containers prevent static buildup….How about an experiment using an ultra-high input impedance op-amp or a JFET in a circuit to measure charge on static-sensitive devices that are so-called protected in their containers? Such as charge transfer (uC's) on/off surfaces of sensitive IC's just dumped out (well, SLID out) of one of those long plastic "IC tubes", perhaps into "half of a Lyden jar"? …now on to the video…

I wonder how many of us coffin dodgers caught the Esther Rantzen reference.
Those SOP boards work fine, they look like they don't have much space for solder, but you can hand solder them easily
Heat the PCB/Sticker with a hair dryer and the label should peel away quite easily.
Half a grand a month, to buy random crap from Ebay and open it on air? Christ, I'm in the wrong business.
Gently warm the PCB to remove that sticker easily, in the same way as you used to remove labels from cassette tapes! Thanks Julian.
Julian, I do (as an other commenter in this thread) recommend you to look at the 10 MHz opto coupler, 6N137.
