  • Awesome! This is just what I needed for some Github integration I was planning on.

  • Thanks for publishing this useful guide. I’ve tried to make sense of Section 15 before, to no avail. Your guide makes infinitely more sense than the legalese on the FCC website.

    Just for my clarification: can a company sell a subassembly (a circuit board) and separately sell an enclosure for said subassembly, and not need FCC testing? I’m wondering specifically if that would qualify the sub-assembly as “marketed as part of a system.”

  • I see a Raspberry Pi powered Spotify jukebox coming my way soon. Ordered!

  • Ah man! I was wondering why I couldn’t find this part, it was going to be perfect for a project I ’m planning. Any reason for it’s retirement? Low circulation? Hard to supply?

    Any possibility of a revival?

  • What is the magic by which one of the red leds is glowing yellow?

  • It’s the iconic Sparkfun red. Incidentally, having never been to a retail shop that had Sparkfun stuff, I bet their section of the store stands out a little bit :)

  • I second the mini LCD request. The schematic makes it look like they are controlled over SPI? How much are they? For $5-10 a unit with SPI so I don’t need to waste a bunch of I/O lines or pay a $10 premium for a serial LCD board, I’d buy some of these for all of my projects!

  • Cool. Count me in if you guys do anything in Atlanta. We have Georgia Tech, Georgia Polytechnic, Georgia State, and Freeside Atlanta all here.

  • Sparkfun is possibly the best company in the whole world. I will be hovering over the submit button with a perfectly balanced cart.
    However, this does create a somewhat interesting problem in selecting the items. There are many possible solutions for $100, and determining the technical value of each item for future projects is difficult.
    Should I hook something up to the internet, add wireless ZigBee (did you see the 40 mi transmitter?), cell phone, huge lcd display (not as useful, but hey, pretty screen), get the SPI button for blinken lights( a necessary item for every major electronics project), get GPS, get some sweet sensors, RFID, Fingerprint Scanner, FPGA, etc.
    I have about 30 product tabs open right now, and I have no clue which will be finally selected. Yeah, gift cards immediately came to my head. Let me know if that’s cheating or not, cause otherwise I’ll probably just get one of them and wait until I know for sure what I want to do before getting anything.
    My hs senior engineering project is about to get amazing.

  • You can probably get away with cutting the 4x4 board into quarters. See this link
    Simon board is only $25, you can simply change the firmware so that a pin turns on every time each button is pressed. The micro can take care of debounce as well.
    The Simon board is $25.
    Or get the freeware version of Eagle and design your own 2x2 board. It’d be pretty simple, as Sparkfun has a part for the 2x2 in their Eagle library that’s available for free. See Sparkfun’s excellent tutorial on schematic and board layout in Eagle.
    Then you send the gerber files off to a PCB maker. BatchPCB works great and is cheap if you don’t mind waiting a while. That’d be about $20 without shipping. And you’d still have to buy the 2x2 pad.
    So all in all it’s probably just easier to get the 4x4 board, unless portability is an issue. Than you’re best off making a board with the 2x2 pad on it and putting everything else on it too. But that takes time, and if you just want a quick and dirty solution, hacking the 4x4 board will probably work.

No public wish lists :(
