Requesting Diodes Through The Mail

My friend Bob recently tweeted this photo of a letter he wrote back in his salad days, ordering a few diodes from Poly-Paks in Massachusetts.

Of course, today, a diode is just a click away!


Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.

  1. Back in the day, I ordered some industrial condensers from “Electronic Section, Unit 16”, and I received some crazy beads in an envelope. Even though they did disintegrate, they held a charge of 30,000 volts before doing so!

    I guess the economy became too bad for them, because I haven’t had any updated catalogs. I guess printing on metal pages was too fancy.

  2. I ordered parts from Poly-Paks. Of course back then the parts were not too expensive and shipping by parcel post was inexpensive (un-adjusted dollars). Of course I remember when there was no UPS and no ZIP code. I made my own PCB’s with copperclad and fingernail polish resist.

  3. Dangit Mike, you beat me to it.

    I was about to recount how two weeks later, they got a bunch of electronics parts they hadn’t ordered, and an instruction sheet on how to build something called an “Interociter.”
