VS 1Spot is unregulated or am I mistaken?

hye juz in case u juz wonderin if 1spots heats up or not...
it does.
seems impossible? but any electronics components produces heat because electrons are being forced to move in the circuits. the basic of energy converting to other forces. Next heat cause expension.. n ya e result is out..

the 1 spot does heat up quite a bit, running mi zoom g2.1, at 300mA, it gets warm after abt half an hour.....

Hey wait! The 1 Spot is a switchmode supply and it's regulated la!
As pc power supplies are of the switchmode design it also means they can be used but!!!
It's the noise and hum dampening that becomes the real issue here. I do believe there's potential solutions out there but you do have to take the noise factor, amperage and polarity issues into consideration. Please be very careful about this because some pedals do not incorporate polarity correction and will thus blow up unsuspectingly if you connect a dc barrel connector of different polarity.
Moo, I would suggest that you either try out different 1 spots, power brick, bite the bullet and try out other power adaptors or simply go the batt route (duracell is best).
Other opinions?

I am going to do so.
But I think I shall skip the 1Spot for the time being, and the power brick.
Either a custom power supply made by a reputable tech or that voodoo labs monster of a power supply.
But the voodoo labs is going to be like how a Peterson Strobe tuner is to me... not needed, but good, so will KIV forever.
I really hope I don't get to the battery route....
Good secondary regulation style circuit normally uses either
1)zener reference voltage source to control driver transistor or
2)780X power regulator IC (loads up to 1amp with proper heat sink)
These circuits are normally tolerant against heat drift factor, noise & supply drift within the power supply.
Slighty cheaper regulated circuit will simply use resistive voltage divider circuit for the reference point, these are more prone to drift.
A feedback comparator and correction circuit improves the reliability further. Where cost concern is ok, this circuit is normally present in switching power supplies too.
Again, cheap is the factor, this circuit could be omited, with the drawback of the drift factor.

Guys,
I've not looked deeply into switchmode designs and stuff like that.
Just thinking, switchmode stuff ARE regulated in term of getting a consistant voltage each time you power up.
If a 9V setting gives 9.2V the first time and underload its give 9.2 and powering it up the next day,week,month will give the same old 9.2, its REGULATED. Thats what I know about that one that I use (NOT OneSpot)
One thing that irks me is that my switch mode power supply(NOT OneSpot) will gives me shocks. Yes... BUZZZZZ, OUCH and WTF.
Something to do with the internal workings of the output section?
And as for what shredcow's observations...
Something to do with the Switchmode output supply impedance that messing with the pedals?
Just guessing. Anyone familiar with switchmode designs?

heh... i know i can get TONS of information and schems from the net but I really don't care about this particular switchmode.
Harddisk space upstairs got limited storage for new information. My information filters out only the necessary.
My good ol multiple transformers, multiple regulators and big assed filtering capacitors supplies makes a lot of people happy. :lol:

goose, it's ok, only few need to catch horse anyway.. most pple go catch spider.... har har..
ed, too much of a good thing may work opposite. over capping could lead to lagging.
But yeah, I share yur sentiments. Good o big iron tranny still best, abiet the emmiting line hum from the coils, for these kind of applications. Which is part of reason for the wallwart design, keep them farther from the operatin devices.
Also problem with switchmode, is that it's not reachable to the average hobbyist. The sm trannys are only avail to production quantities. Else have to find ready built ones for adaption.
