Mains filter for small linear power supply [14 articles]
Alan Slough - 2010-02-23 15:00:00
I have a 8W linear power supply that I wish to protect against mains-
borne interference. The linear power supply is powering up a board
containing a simple measuring circuit and some CMOS 4000 seri...

Joerg - 2010-02-23 14:24:00
Hello Folks,
Annoying: Li'l brake light randomly comes on in the dash of the Toyota.
Has nothing to do with whether brakes are used or not, purely random.
I've traced it down to the master brak...Bipolar transistors in reverse [13 articles]
E - 2010-02-23 10:13:00
Got just two nice lab psu (100W and weight only 13 kg) off Ebay.
So to put them in some use I measured how well some bipolars work
with collector and emitter swapped.

Daniel - 2010-02-23 10:08:00
Hello,
A Z=1k source has an output signal with two frequencies, which I need
to detect independently with two amplifiers.
Signal frequencies are in the low kHz range.
One signal is 100 mV (f1), ...45-degree diagonal cutters? [98 articles]
DaveC - 2010-02-22 20:17:00
I used to own a pair of flush cutters where the jaws and the handles met at

Bill Sloman - 2010-02-22 17:14:00
I should have a new one tomorrow. I'll be incommunicado for a at least
a week or so, if everything goes according to plan, as it does better
95% of the time.

...Magnet as SMD tool [8 articles]
Jan Panteltje - 2010-02-22 15:42:00
So ,as some SMDs turned out to be attracted by magnets,
then why not use the magnet as a tool to place the SMD?
Gave it a try, and this works MUCH better then pliers or tweezers!
Holds the part ...160Mbps fibre-optic receiver quantizer [2 articles]
Winfield Hill - 2010-02-22 13:36:00
In their app note an1123, Avago recommends the ML6622
for a high-speed quantizer in a 160Mbps receiver, but
this elegant Micro Linear part has been discontinued.
I suppose an LVDS receiver can ...Hand (De)Soldering Altera's 144 Pin EQFP Or BGA [5 articles]

Hi,
I have a home project currently targeted to an Altera 144 pin
EQFP. There is a pad on the underside that must be soldered to
the ground plane. Is there any way of (de)soldering that pad
