  • Certainly such organization is vital in an area that is shared, such as a school or club.

    However, in a personal space not a showplace some slack might be in order. I can instantly locate the Jacobs Chuck wrench or any other tool that I bought 40 years ago, I use labeled shoeboxes for parts and have separate toolboxes for my most common tasks. Between my ears lies a marvelous card catalog.

    A (totally) clean desk is a sign of a diseased mind.

  • What capacity & class will this handle? Some SD readers only go up to 2GB, others max out at 32GB.

  • Overwhelming. I hope you guys are going to have some examples - a kit or a bill of materials or wishlist that I can just add to my cart. Some tutorials also I hope.

    On the downside, how come you don’t carry Makerbeam, Openbeam, or Microrax, something that would build 3-D printers and CNC?

  • How much current can this supply to each device and total? And if I plug it into a USB 3.0 host, will it provide more juice?

  • If you are concerned about FCC compliance, just get your Ham radio license. It’s an easy enough test and Morse code is no longer required. Then you can work comfortably under Part 97 rules, and add on a better antenna for the range.

  • A bit of discussion of solder itself might be worthwhile. I grew up with 60/40, gives me nice working time. 63/37 is the eutectic, freezes faster and has a little lower melting point. This new-fangled ROHS stuff takes more heat, doesn’t seem to flow as smoothly, and over time can grow little whiskers, I don’t like it but maybe I’ll come around.

  • I am looking at the RedBot as an entry-level complete robot kit, and the little red magnetic screwdriver is a nice touch. However, when I got to the Accelerometer I found some unplesant features. (1) soldering to to mainboard is required, unless I buy some female breakout headers and solder them. (2) This accelerometer (and its example software) uses up the SCA/SCL (I2C) pins without allowing additional I2C devices, and the example software doesn’t even use wire.h to access them. I’d much prefer a 1x4-pin daisy-chained physical interface. Please tell me I’m wanting something stupid.

  • Hi Dave,

    Can you tell more about the radio transmtter system? How much power does it run, what band, what FCC license is needed? From the link it looks like a Radiometrics HX1 on 144.390, but it looks like your Yagi is too small for 2 meters.

  • How good is the regulation on this brick?

No public wish lists :(
