Individual of modest ability.

  • The dental hygiene droid failed the alpha test due to yet another small, but significant, error in metric unit transformation.

  • I found 2058943-5 to be very close, but not quite the correct connector. The guides on the side needed to be removed (x-acto) and even then was a little chunky to fit easily. But in the end, it seems to fit (never force anything, just use a bigger hammer).


  • It’s can also be a question of “Which companies are doing the right thing?”. There may be some companies who have yet to realize that they are not in compliance.

  • Yeah, definitely the 1970’s for the battery club (for me). My parents bought me a one of the “NNN in 1” kits to keep me from disassembling other (more expensive) things. Battery club, buying piddly bits, pouring over the catalog, and always keeping me thinking. That was the big pay off for me: it programmed me to think in terms of: “What can be made of that?” and “How does that work?”.

  • It looks like they wrapped the Yun stuff into the common distribution. That’s great! Thanks for the heads-up!

  • Mr. Grady, to make it clear: Must the robot climb UP the stairs or can we pick the direction vector?

    (I may have a single-use down-climbing robot ready to enter now.)

  • 10.5mm as indicated on the data sheet.

  • Great explanation Doc Pete! Thank you! If i might “Me Too” for a moment: I am currently doing roughly the same thing with my desk. Tried using the strip LED’s from the hardware store - but these use the LEDs as rectification to keep the part count down. I can really “feel” the 60Hz - especially when i have a migraine headache. So i wanted to use a more CW light/voltage source. Also, quick changes in brightness are an issue. So I use the Redboard to slowly fade in and fade out the lights using the PWM into the FemtoBuck (a very neat device!). With the instructions and parts from SparkFun, i can make something that more closely matches my “special” needs. Very cool! Mark

  • Thank you for a very timely and pertinent post. Are you reading my mind?

  • Shielding, which you mention, is a challenge because the shielding must be thick and dense to be effective. “Thick and dense” means “heavy” and which in turn means “expensive to launch”. So a custom designed self monitoring part will probably be “cheaper” than simply shielding an off the shelf part. Here on earth (like in radiation therapy) we use shielding and preventive replacement and it’s more cost effective. Replacement is tougher when the device is outside the Van Allen Belt as well.

No public wish lists :(
