  • Product KIT-09882 | about 2 years ago

    This kit was a great idea for me! Made a custom PCB with lots of SMD chips and components… then figured I’d try this kit first before assembling my board. I’ve now destroyed 2 components, burned off 2 pads… Good to do this first. Maybe I should stop using lead-free solder…

  • Tutorial - Controllable Power Outlet | about 3 years ago

    I’ve been wanting to build my own relay box for my lamp (incorporate an RTC and an IR sensor, etc) but wanted it internally powered… and was trying to figure out a good compact method.
    I eventually found schematics/pictures for old disassembled X10 module/mod directions.
    here
    Still a little big though to put a transformer on a board, maybe I’ll try with this instead: here
    Anyone ever do anything like this (on-board power)? I’m really new at electronics so any advice is appreciated.

  • News - Another Extra Epic Thursd… | about 3 years ago

    The cynic in me says, “if they’re spending so much, why does sparkfun need to give them free stuff?” hehe
    How about giving out free $5 coupons towards a $200 purchase. Sparkfun should give me free stuff for my business advice :)

  • Product PGM-00014 | about 3 years ago

    I bought the beginning microcontrollers kit which came with the parallel port programmer, then realized my USB printer adapter wouldn’t work and neither of my PCs has a parallel port.
    I then used a transistor and some resistors to convert the parallel adapter into this part (from schematic). It works with the USB serial adapter (Prolific)…. Only it works at ~5-10 bytes/sec, meaning a 1.5 kB program takes ~11 minutes to download.
    I got so fed up I just ordered an Atmel AVR ISP2 usb adapter from digikey.

  • News - AVC Reminder | about 3 years ago

    I can’t make it to Colorado unfortunately. Anyone ever try to automate a real car as an entry? It might not fit through the 3' ring, but it might certainly “crush” the competition! (hopefully not spectators)

  • Product SEN-10167 | about 3 years ago

    I made some code and have been polling this with my ARMmite at 1 s intervals (using C, not BASIC). But while at first it seemed to work correctly, now it is returning 0 as the checksum (still giving numbers that seem correct for the Humidity and Temp though)…. Odd.

  • Product SEN-09569 | about 3 years ago

    Couldn’t this work? http://search.digikey.com/scripts/DkSearch/dksus.dll?Cat=2360393&k=33213

No public wish lists :(
