  • Product ROB-12097 | last month

    No, 0.08" diameter is implausibly small. I think the holes must be based on the Dimension layer (20) rather than the Holes layer (45), which makes them about 0.065" radius, or about the right size for a #5 machine screw.

    Could you tell me the diameter (or radius) of the standoff/mounting holes in the four corners? I can see in the EAGLE board file that they’re positioned at X = 0.10" and 3.60" and Y = 0.10" and 1.85"; and it looks like their radius is 0.04"; but it’d be nice to confirm that before laser-cutting my own chassis (because I think I’d rather use different wheels than those that come with the Magician chassis).

    As others have noted, something that can be done with a rigid board is not a cool flexible circuit design. And I understand the reluctance to use this for an application that must bend in use when you don’t yet have experience with the way it holds up to repeated flexing, leading to Pete’s suggestion that the right design will use the flex during installation but remain stationary once installed.

    One thing that comes to mind is flex versions of SMT breakout boards with the breakout at the head end, several choices of strip lengths, and the corresponding socket for the tail end. Assuming the White Flex Circuits support vias, the flex strips could be double-sided and extremely narrow. This would allow a great deal of leeway in physically routing (low-frequency) signals from e.g. SMT sensor ICs back to control boards in customer projects, something that’s clumsier today using breakout boards and fly wires and bulkier using breakout boards and ribbon cables.

    In Wichita, KS, try Lloyd’s Electronics. Granted, they’ve branched out into parakeets and they’re often quilting in the back room, but they’re still the only place in town to go when you want components, consignment, and kits.

    Hm, this brings to mind an interesting new sales model:<br />
    <br />
    1. Create a product retailing for $400 with interesting technology bits inside.<br />
    <br />
    2. Put up $1000 bounty to the first hacker to do X with embedded technology.<br />
    <br />
    3. Sell lots of units to aspiring hackers.<br />
    <br />
    4. Profit! :-)

    Pretty please, an inductance meter to go with the capacitance meter???

    First thought: Yesss! I can get that graphic LCD screen I want, and some XBee gear, and … and …
    Second thought: Y'know, I have a good job and I can afford to buy my own SparkFun gear. I think I’ll leave the free stuff for the people who’ll appreciate it even more than I would.
    Third thought, carrying #2 a step further: Nate, if you wanna make a product code that costs $100 and sponsors another seat in the giveaway (obviously not tax deductible for the contributor), heck yeah, I’ll buy one. I expect it would add complications you don’t care to deal with, but it’s worth offering.

No public wish lists :(
