  • Thanks for the explanation.

  • Rather than naysay or whine, I will just order 4 packs of these, and give them to my grandkids and the roboteam I work with. I’ll report back later on what they do with them.

  • I met Dr. Grace Hopper on a couple of occasions, when she was on speaking tours. She told a story about a project for the Navy, in which she had a Data General minicomputer with about 16K of memory. She told the Navy she could build the project using the DG machine, and they had doubts. She reminded them that she and a small team had built the first COBOL compiler on a smaller (4K, if I remember right), so not to worry. Later they named a warship after her!
    The moral of that story, if there is one, is that if you tell a smart woman she can’t do something, you’d better step out of the way!

  • I just finished building the Big Time Watch with my granddaughter and the Simon game with my grandson (11 and 9, respectively). My approach to the soldering part was to show them how by soldering one joint, then watching as they soldered all the rest. The girl is now proficient with soldering, and the boy is nearly as proficient. Both projects worked immediately on completion, and now two grandsons want the watch! Thank you for a couple of excellent through-hole soldering kits. We may soon try reprogramming the Simon. The boy has a fiendish idea for Simon reprogramming.

  • I was adjusting one of these last week and the knob came off, revealing a little slotted shaft. It goes back on easily, but revealed that this little trimpot can be used in close quarters, with a screwdriver, with or without the knob. The shaft can be set up to protrude through a hole, as well.

  • Don’t mind Jake. He’s just molting.

  • Thanks for the opportunity to help the affected families. I found it also easy to donate through the United Way link.

  • Without bad luck and dumb luck, he’d have no luck at all. It’s not easy being yellow (sorry Kermit).

  • I haven’t known about Sparkfun for its entire lifetime, but I wish I had. Whenever someone asks (or doesn’t), I recommend Sparkfun. Your company has a great blend of customer care, originality, honesty, and openness. Keep it up!

  • My favorite Heathkits were the DX-40 transmitter (AM and CW), and the VF-1 VFO. The DX-40 went together easily and worked the first time. It was my first AM transmitter. The VF-1 plugged right into the crystal socket, and also worked the first time. Before going on the air, I checked its calibration against a surplus BC-221 frequency meter, and it was dead-on accurate. Right out of the box. Amazing.

    A point about what was attractive about Heathkits was the economics: some of the gadgets couldn’t be had elsewhere at any price. Some were a bit less expensive than a manufactured equivalent. All of them provided educational value that was priceless.

    Another point - about encouraging kids to do things with electronics: When I was 14 or so, my father noticed my interest in electronics. The first Heathkit (a little mono amplifier) arrived at Christmas. Other devices followed. The most important thing Dad did (I didn’t realize its significance until years later - I thought all Dads did things like that) was to enroll himself in a night electronics class at the local junior college. He worked a deal with the instructor so that I could tag along, though I wasn’t eligible to enroll. We took two semesters of basic electricity and electronics, and had a ball. That led me to a satisfying career in electronics, computers, and software engineering, and a lifetime of fun with ham radio.

    Heathkits provided the fertile soil for those seeds.

    My grandson (7) and I built the Simon kit a few months ago, and I think he’s hooked.
