    Reflow Bga chip.

    It is also possible to do this with 2 solders having different melting points, or simply gluing the components on one side (typically the bottom side :-))

    Timer circuit help

    You could spray water on the back of the panels. No problem with lime buildup there. However the panels are not likely designed for water to be sprayed onto the back of the panels (as they are for the front).

    Hot rodding a cordless vacuum cleaner.

    It is likely that the older motor was a traditional DC motor and that the new one is a BLDC (brushless DC) motor. The circuit board with the newer motor (if I am correct) is essential since a BLDC motor can't be connected directly up to a power source. Whilst DC is part of the name of a BLDC...

    Light sensor motor control

    I don't see anywhere where a 10W resistor would be needed. Details matter when you're drawing circuit diagrams.

    Light sensor motor control

    That circuit doesn't make much sense. The motor will run continuously.

    What did we do before LEDs

    What did we do before LEDs? The same, only at a lower colour temperature and with a lot more power.

    My 2 year Electronics Point anniversary

    On the positive side, I don't expect my post count will be changing much in 918 years. That would be an ideal time to make your move.

    Protecting I/O lines of microcontroller

    A series resistor, reverse biased diodes to the supply rails, zener diode to ground, it a combination of more than one of these. The existing protection for CMOS is akin to a combination of reverse biased diodes anda series resistor, but it isn't expected to (or capable of) handling a...

    Where to get shorting strap for terminal posts

    I have a piece of equipment missing some shorting straps for use when 4 wire measurements are not going to be used. Purchasing them from eBay (or any other obvious choice) is ridiculously expensive. Anyone know a reasonable alternative? I guess an appropriately shaped piece of wire would...

    Looking for Datasheet on old Texas Instruments strobed Digital Clock Chip, M35020

    Aaaaaagh! I have this almost irresistible urge to travel to Tasmania for a "Tip Shop tour".

    Looking for Datasheet on old Texas Instruments strobed Digital Clock Chip, M35020

    If there is any scanned documentation it would be really handy if you uploaded it here. You can give the internet some of the stuff is forgotten.

    My brand new oscilloscope

    Here's the recapping so far: the red and the orange caps (just below and to the right of the switches at the top) are in a position that's really hard to get to. I'm contemplating leaving them for now.
