Re: Power bricks in series?

"Either" should be neither cuz you don't know how the load is wired wrt "earth".

Re: Power bricks in series?

The load will determine the current (amperage) that will be drawn from EACH power supply (as the load current flows through one power supply, then the other before getting to the load).

This sort...

Re: best cheap/free scores 1.1

You have to start earlier (in life) and keep remembering that anything coming in has to be offset by something going out!

Re: Dimmable LED incandescent replacements

That's what we have. The problem doesn't appear to be IN the dimmer but, rather, in how the lamp handles a certain "operating point" -- they dim linearly to a very low level. But, just before...

Re: Dimmable LED incandescent replacements

I think the bulbs are the bigger part of the problem. They've already got "smarts" to figure out how to drive the LEDs off of the AC signal so need a way to sort out when that "AC" has been...

Re: best cheap/free scores 1.1

I decided against accepting the donation -- it would be yet another
make/model that I would have to support and, with just 30 pieces, the
effort didn't seem worth the time.

Dimmable LED incandescent replacements

Has anyone had success using dimmable LED replacement bulbs? Which brand(s) and which dimmer(s)?

Despite using "recommended" (by lamp manufacturer) dimmers, we seem to end up with low frequency...

Re: Help on replacement of touch-sensitive power button

It could also be capacitive or thermal.

Try "pushing" it with a wooden dowel (so your body heat and "load" is separated from the switch).

Re: best cheap/free scores 1.1

The stands showed up, today, so now I'll have to figure out where to store THOSE (I'm leaving the monitors under the bed as they are already wrapped up, nicely)

Of course! The four 3007's I have in use have their stands stored out in the garage while each is mounted on an articulated arm. This gives me access to the space immediately below the monitor...

Another pair of Dell 3007's that appear to work. But, no stands (WTF??!). No place to USE them so I'll have to store them as future spares. (I already have 4 in use) Of course, I'm running out of...

Re: Laminator blows fuses and trips the mains - but not when on my ispolation transfo

+1

3A @ 220V is 660VA -- probably a sizable load for an isolation transformer. If it was fused at 5A then it is likely that it draws close to that (at least at some point in its operation).

If...

Sorry to hear that. Apparently, about 10% of men over 50 develop ET.

Re: Running a microcontroller in car - power supply aspects

You may as well push for a 2A03! <frown>

The 6502 is almost as quirky as a PIC and omits many of the features that are now commonplace in MPUs and MCUs.

While the dual accumulator 6800 is a...

Re: Running a microcontroller in car - power supply aspects

PICs are a lousy place to start as their architecture is really quirky.

If you have NO experience with CPUs/software, your best bet is to pick one of the "classic" processors (1970-80 vintage)...

Dunno as I have no experience with that hardware nor the "system" software.

Re: Help on replacement of touch-sensitive power button

Re: Running a microcontroller in car - power supply aspects

I understand that's what you THOUGHT you were doing. But, in practice, you're NOT!



If PCIE is actually defined to be "5" (and not 00100000r2 = 0x20), then:
GIMSK &= (0 << PCIE)

Re: Decorative Solar Lamp Question

Are you measuring the unloaded output of the panel? Or, is the load possibly dragging the output down?
