  • QL code: hit me!

  • … SQUIRREL! - Oh snap! - I’ll just chew on this box …

  • This is like going to a baseball game and bringing you mitt in hope you might get a baseball with the exception that no one is on the field but a machine that spits out a ball at random every 12 seconds. Boring. You guys might of had fun setting this up but this Free day as no fun at all and probably causing more long term medical bills in wrist injuries than the giveaway. SparkVegas dot com

  • I hope you find a better way next year - CAPTCHAs are not FUN and are designed to verify your un-botness only once in a session. I tried a few and only getting 1/3 of them correct, I got bored.

  • I am the droid your looking for

  • Looks like it would not take much to rig up a .1 header given the gold pads next to the connector. Just epoxy a 0.1 header on top of the current connector and use some “wire wrap” wire to make the connections.
    Something like this ([-] is plastic part of header to epoxy.)
    ….[PCB IS HERE]

  • I have had a spool of Kester rosin solder for a least 15 years now and I not noticed any degradation. I use it to solder even the smallest SMD’s without any issues. I never even thought about it possibly going bad until reading this thread. You mileage may vary I guess.

  • Assuming they are indeed fake parts, then no reason to assume that all the chips look the same inside.

  • My custom board works fine with a 10uf ceramic chip cap. I wonder what the ESR of that tantalum cap is on this board? My layout is about the same except I have a 4 layer board. My guess is that this chip prefers a ceramic cap.

  • For those having problems reading data in continuous mode read page 18 in the spec… the the 5 milli-second power-up time is important!
    from page 18:
    To change the measurement mode to continuous measurement mode, after the 5 milli-second power-up time send the
    three bytes:
    0x3C 0x02 0x00
    This writes the 00 into the second register or mode register to switch from single to continuous measurement mode
    setting. With the data rate at the factory default of 10Hz updates (100 milli-seconds interval), a 100 milli-second delay
    should be made by the I2C master before querying the HMC5843 data registers for new measurements. To clock out the
    new data, send:
    0x3D, and clock out DXRA, DXRB, DYRA, DYRB, DZRA, DZRB located in registers 3 through 8. The HMC5843 will
    automatically re-point back to register 3 for the next 0x3D query, expected 100 milli-seconds or later.

No public wish lists :(
