Manufacturing Monday – Microscope inspection… When your parts get small, it can get really tough to see whats going on with them. Especially if your vision is only so-so, having some assistance with inspection is an easily solved problem. When we were at school, the lab had a really sweet confocal microscope. You could really see quite nicely and solder while looking thru the microscope. It was wonderful but unfortunately a bit too expensive for the common user.
Now we have our own lab, and instead of a massive scope, we decided to go with a more portable USB microscope. These are neat in that you can easily take photos/screenshots – but you do need a computer to view the images which makes it a little less flexible than a full microscope.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

I have a LOMO SF-50 stereo microscope with a swing arm and ring light, and love it… I just checked on opticsplanet.com (where I got mine from) and the price is down to about $290… $50 less than I paid a couple of years ago. What I don’t have for it – and kinda wish I did – is a trinocular head, so I can mount a camera to it and still look thru both eyepieces.
I also have a cheap $20 eBay no-name-special stereo microscope, that works OK as well… however, it’s a fixed magnification scope, and doesn’t have a swing arm, so it only works for small boards. It’s also plastic, so care is required when working with a hot soldering iron under the scope.
Right after a good soldering station, I would recommend getting a microscope. I’ve tried the head-mounted magnifiers, and several kinds of arm-mounted magnifiers (the lamp type, the smaller “helping hands” type, etc)… and a real scope beats them all.
Those look nice, but I was surprised to see how expansive they are.
