I couldn't resist buying the cute 101I'll probably use it for quick and dirty measurements on the bench.I was also given a nice Fluke polo shirt, well worth the 33 euros I paid for the meter, just by itself!So if anybody is in Malaysia at the moment, it might be worthwhile paying them a visit too.
Cool Pease circuit - floating simulated inductor - Page 1

content: Just stumbled on this and thought I would share it, in case it's useful to anyone. It's certainly clever. We've all seen the op-amp simulated inductor, but one end of that inductor is grounded. Bob Pease gives a floating version in this videoI had to tweak the series resistance to get it to follow a real inductor. Offsets need to be closely matched (microvolts).

Yes being +5 VDC and no being 0 VDC. There is no DC offset needed, it is hard enough to get them to comprehend yes and no and we don't want to get into shades of grey if we include an offset voltage.

content: Quote from: IntegratedValve on January 07, 2014, 05:25:01 amYep, as the wiki says they are popular in phone circuits, called DAA (modems, fax machines) and FXO (Foreign eXchange Office) which is the phone end of the circuit, which may in actuality be a physical phone connected to a central office (CO), or the line cards in the racks at the customer premises of a private business exchange(PBX) that go to a CO... basically the FXO is your end of the line to the CO... the CO end is called an FXS (although a PBX served by a digital line these days may have local FXS line cards that go to local POTS phones that are then the FXO end.The gyrator used in the DAA/FXO holds the DC line current , so the DC current doesn't have to flow through the transformer that is actually on the line. This allows the transformer to be made smaller and cheaper, and thus more line cards can fit in a rack. By the way.. more old terminology.. this is called "wet" and "dry" ... "wet" means the transformer is designed to carry the DC current without saturating , "dry" means it does not. All modern telephone circuits use dry transformers and a gyrator circuit for the DC current loop.

content: Since there are so many enthusiastic people in electronics here, I am going to post this question in this forum.We all like to tinker with electronics, make projects using FPGAs, Microcontrollers and occasionally, circuits using discrete components to do analogue signal processing. We may also like to create schematics, PCB layouts, use MATLAB and other more complex abstract ways of circuit design. It would be good to see a place where details of some serious projects are given that we can read, recreate, and learn from. By serious I mean projects that are not as simple as lighting an LED if you know what I mean.Where can I find such a treasure of knowledge+experience?The intention here is to have a list of things from the folks here. I know that some are just obvious from google search and EEVblog. Having a list of the best at one place for anyone who needs it in the future will be a good idea.

The "receiver ID" button tells me this:Code:COPYRIGHT 1991-2004 MOTOROLA INC.SFTW P/N # 61-G10268ASOFTWARE VER # 2SOFTWARE REV # 0.1SOFTWARE DATE JUN 09 2004MODEL # P273T12T18HWDR P/N # 2SERIAL # P0BQE7MANUFACTUR DATE 4M21I know the M12+ receiver is seeing satellites, as the "Azimuth & Elevation Window" "Satellite Info" tab shows "Visible Satellites: 10" and lists ten PRNs with slowly changing Doppler, Azimuth, Elevation values for each, and "Status OK". However "C/No" is 00 for all of them. In the "Azimuth and Elevation" tab I see the satellite positions and green trails behind them. In "Navigation Window" I see "Receiver Status 12 Channel (6004) Acquiring Satellites Antenna Sense: Under Current". The self-test button shows everything OK except for the antenna undercurrent.The board has no backup battery and this was a cold start. I assume it takes about half an hour to download the almanac & ephemeris from a cold start. However it's been running for more than an hour with no position fixes yet, even though there should be no signal level problems in this location (other GPS units have had no trouble here). Is there anything obvious I'm doing wrong?

content: Got it working. I misunderstood "satellites visible" to mean that the receiver was receiving signals from satellites, but just didn't know the exact orbits yet. That seems to be incorrect; apparently it just means that the satellites "should" be visible based on the rough coordinates and time of day that I entered, but implies nothing about actual signal reception. Apparently it really wasn't getting any signals at all. I changed to a different antenna, and it immediately saw a few satellites and acquired a 3D lock after a few minutes.

content: I've found that sometimes the discussions turn out to get a little mathematical and it would be great if the option to typeset math within the posts of these forums was available. It would increase the quality and readability of such posts considerably.Now this is possible to do that through MathJax, that is platform independent (it even works on android stock browser on cheaper smartphones):http://www.mathjax.org/It is easy to implement (just a few lines need to be added at the header of each forum page) and it is used by Stack Exchange among several other web sites. It is also offered to registered users as a beta in the Wikipedia website. Here's an example what it looks like:http://physics.stackexchange.com/questions/90048/relationship-between-mass-preserving-four-fources-and-proper-accelerationThe math is beautifully typeset using the Latex typesetting engine and if mathjax for some reason would fail to render, you'll at least see the latex tags for the math typesetting which really is quite readable for anyone who is into math.

Can someone please tell me how to select the wire size to connect the PCBs together? I will post a picture of the schematic if it will allow me. The eight gauge wire was provided to me in the kit and I connected where the schematic called for "thick trace wire" and the white wire was provided in the kit and connected where the schematic called for "twisted shielded wire", however there is the matter of figuring out what size wire to use between the rest of the PCBs. I believe that using Theveinin and Norton principles might be appropriate but I don't know how to measure these on an actual circuit. Even if all you can do is recommend a good instructional video I would be greatful as I have not been able to find one.For now, I have used telephone wire to connect the subciruits together as a stand-in to get an overall flow of the circuit

Some arcade boards need another connector to support additional inputs, called a Kick harness.

Typically the boards conform to the JAMMA standard which is a single card edge connector that does coin, 1p/2p, joysticks, a certain number of buttons, sound and video.The game is usually a cartridge with a separate small part that functions as a decoder or a license so to speak.
