  • Order 43706, December 2007. :) Delighted to have been along for the ride thus far!

    As much as we enjoy the way Espressif has shaken up the wifi market (with a chip that initially had almost no support and even less documentation, and had to be figured out by hackers before it made a big impact), how do you feel about the cheap clones of SFE products on eBay and elsewhere? They’re also poorly documented, also have no support other than a refund if you’re lucky, and I find myself struggling sometimes to explain why it’s important to buy from nice folks like Sparkfun who document and support their products.

    I’m curious for perspectives on this. Of course there’s always competition, but how do y'all put the different players and factors in context and decide where to spend your money?

  • It was written in 2005 and still runs today with no modification. Most websites from 2005 are all sorts of broken or obsolete. (Suppose they’d written it in Flash…)

    Conclusion: Excel is a more stable environment to write simple tools in.

  • Yes, but if you’re using double-sided foam tape or something to hold it down, be very careful of how you push the glass into the tape! I’ve cracked the corner of a similar display with very little pressure; it’s thin glass and not meant to be mashed on. Consider laying the glass down on a table and flipping the board over it, pushing against the board rather than the glass.

  • Replying to myself here with a bit more detail:

    “First-order retrievability” is an even bigger deal in a shared space than a personal workshop. Because it equates to first-order-put-away-ability, which turns out to be the crucial one. People will dig to find a tool or a part, if they know where to look, but they will not dig to put things away. At least, not everyone will, and if you haven’t tried to maintain resources in a shared space yet, I have some sad news about the distribution of messy jerkfaces among your idealized amazing-hacker-member population.

  • I love this, it validates so much stuff we’ve already been doing at our hackerspace! Most of the members immediately understand the “clear workspaces completely when you’re done” concept, and this article is further encouragement to nudge the others into playing nice with the shared toys.

    Here’s a fairly recent panoramic shot of the lab: https://www.i3detroit.org/wiki/File:Eroom-pano-resized.jpg

    And the parts drawers themselves, this is definitely dated (we’ve added 4 more cabinets but things are largely in the same relative locations, even as things shift slightly): https://www.i3detroit.org/wiki/File:NewERoomWithOverlays-output.jpg

  • Sweet! This has a high enough range for DIY TPMS…

  • For the love of your nose, RUN THIS THING OUTSIDE for a few minutes when you first get it. The brand-new heating element is coated in something that, when heated, quickly coats your sinuses and throat in a truly yucky feeling.

    Other than that it’s great.

    Oh, and Sparkfun’s is a better deal, too. :)

  • The capacitance also decreases as the voltage goes up: http://www.maximintegrated.com/app-notes/index.mvp/id/5527

  • Whoah, cheapest Kelvin clips ever. Yoink!

No public wish lists :(
