  • Is error handling done by the on-board 8051 'complaint' processor?

    But in all seriousness, this thing looks pretty cool.

  • There are a bunch of commands for talking with SIM cards, but as for using a cellular network, you're going to need more than just a card to get it working. SIM cards have a bunch of authentication mechanisms, including computation of encryption keys (one command, called "Get Challenge" involves calculating security codes from a 64-bit number) and also communication to and from the local cell towers.

    You're better off using a dedicated cellular board, or picking up an old cell phone that has a SIM socket and isn't SIM-locked to its original carrier. Many Nokia phones have a serial port (called F-bus) and there are (some) articles on commands that can be used to send and receive text messages.

  • I haven't tackled TQFP chips yet, but I have taken out several SOIC and SSOP chips, no sweat. I wish I bought this earlier, then I'd have avoided several ruined boards because of lifted pads and such.

  • This stuff is amazing. It was able to re-tin a soldering iron tip that was exposed to about two weeks of continuous heating (oops!) with no problems.

  • As far as I know, no. This can only work as a USB device and not as a host.

  • It's not the traditional usage, but I've found an alternative use for desoldering braid.

    I have a lot of USB drives that have some rather stupid keyring design (you can't attach a normal keyring on it) and by threading the braid though and soldering it, you get a strong and flexible keyring.


  • When a breakout board is created, will it have voltage regulation/logic level translation?

  • I bought a bunch of these and I cannot for the life of me get these headers installed onto a circuit board. They just won't get in even if I try to force them onto a PCB. Anyone have tips on how to make these work?

  • I've got some LCD code for the MSP430.

  • Yes you can. These capacitors have a very low ESR and can provide large amounts of current.

No public wish lists :(
