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.

differential notch filter with high out of band impedance [8 articles]
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
about a 45-degree angle. Made for a nice tool for getting in between
components when you needed to nip something off flu...The Modern Coffeehouse [6 articles]

...OT: aortic valve replacement [46 articles]
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]
Abby Brown - 2010-02-22 12:52:00
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

krw - 2010-02-22 12:50:00
We're having problems with defective (or damaged in reflow) audio
transformers and I'm not buying what the manufacturer is telling us. A
significant number are falling out during manufacturing wit...LTspice issues. [14 articles]
Jamie - 2010-02-22 09:25:00
I don't use LTspice a lot how ever, recently I have been poking around
with a simple buck circuit that just does not seem to do in spice as it
does in real life. I can put those little things ...
