Got some actual work done the past couple of days, notably a minor respin of a client's board (which, owing to signal re-routing getting unexpectedly fiddly, took slightly more labor and a whole lot more elapsed-time-while-the-computer-chomps than I'd expected).
Next phase of that project involves studying a mess of somebody else's code, so I print out a few source files, selected sections of a couple of data sheets, and so on.
And my laser printer runs out of toner. I don't recall seeing the blinky warning light!
Oh, well. Amazon promises to have a new high-capacity toner cartridge to me by Sunday. If I really need to print stuff before then, I can always load the inkjet printer with letter-size paper.
Maybe I should spend Saturday hiking, or gardening, or otherwise not at my desk. With the weather turning warm, I probably ought to rebuild the kitchen-garden drip system.
(And now I'm realizing that probably $300 or so worth of office supplies last year were legitimate business expenses, but I hadn't tracked them as such.)
Update: That was the end of the work day, but, still having some time before Tinga absolutely, positively, has to be put to bed and the lab closed up for the night (that being where she sleeps), I decided to have a go at repairing the FRDM-KL25Z board whose MCU was no longer responding to the debug interface.
Well... 80-lead QFP and lead-free solder... fun. Goober on tin-bismuth low-temp solder paste, and go around melting it with a nice hot iron, making sure it has time to diffuse under the leads and alloy with the old solder. Then goober on a bit more, and apply hot air until it melts all around, and skoonch the chip off the board. Clean up, warm the board back up a bit, and apply a thin film of the low-temp solder to the pads, then put the new chip in place, try to line it up with the pads, and apply the hot air again. Then wick off the blobs, inspect, use hot air again to correct a slight misalignment, and clean up again.
Back to the desk, plug it in, load the blinky program: success!
Now if only I knew what went wrong with the original MCU, and why... but, now having two instances of this board, I guess I can keep one as an mbed and risk the other playing with KDS and its debugger.
