Hi - I'm planning on using a old computer PSU I have laying around to power something I'm working on. I remember reading that to do so , besides...
Hi - I'd really like to get a scope and a logic analyzer. I'm a poor college student in debt to his knees, so I really don't want to buy them......

Hi - I'm building something that was designed in Europe. Thus it was designed with many parts that are only (as far as I can find) available from...
Hi - has anybody seen any board mountable 5V DC supplies? Like something that would take a 120VAC signal and output 5VDC. It wouldn't need to...
Hi - so I avoid connectors that you have to crimp at all costs, but occasionally I get stuck having to deal with them. Normally I just kind of...
Hi - so I'm trying to simulate a circuit. I first set a DC sweep on the input (V3): [IMG] Then I hit the run button and choose node 6 (the...
Hi - I'm just wondering - I've been doing alot of layout work with Eagle as of late - and I've noticed that most components have round pads, but...
Hi - I need to find 2 rather non standard DB9 connectors. First of all - I need to find some right angle board mount connectors that can fit in a...
Hi - I was wondering - if I were to use an op-amp as a buffer, with only a positive input (thus the output would also always be positive) - would...
Hi - I was just given a bit of a nasty project yesterday. I need to take 10 0-10 V inputs, and then have 10 0-400V outputs that correspond...
Hi - so somebody drew up this circuit for me a year or so back, and all of it seems very basic and easy to understand, except for the diode. What...
Hi - I need to get 3V from a 5V power source. I had originally planned on using a LM317, but now I just realized that LM317s require a minimum...
I'm hoping to find a cheap HD44780 LCD I can tinker around with (in conjunction with an AVR). So I've been looking at allelectronics:...
Hi - so I'm doing enough surface mount work nowadays (I'd say about 75% of the soldering I do these days is surface mount) that I need a tip...
Hi - so I'm working on putting some final details on a project of mine right now - and I've decided that surface mount would be best for it. So -...
Hi - so at work we are looking at buying a DC 200V power supply. Would need to be maybe 50W or so. We have someohuge 48V DC power supplies. Is...
Hi - can anybody give me some help on choose crystals and matching caps? This is something that has always been confusing to me. For example, I...
Hi - in the near future I'm going to be making a circuit that makes use of some QProx chips. Specifically, I'll be using the QProx QT150 (well...
Hi - I'm in the final stage of a project where part of it will need to be able to control a computer running windows 98 through the serial port....
