If you used a venerable Simpson 360 or Triplett 630......

So now that the MCM we knew for years is now under the Newark / Farnell / Element 14 group, what's your opinion?
Good, Bad, Indifferent?

Looking down the road, I may need a quantity of PCB's fabricated. Maybe just bare boards, maybe stuffed, I'm not sure right now. Naturally, since the cost is low, looking offshore is an attractive option. If anyone has been down this road, sharing their experience would be a great help. I would thin...

I just had the need to solder a 100+ Switchcraft A4M and A4F connectors. I got a great price on the large quantity I needed but it seems many of them may have been old new stock. The contacts, which I assume are silver plated were tarnished and the soldering was not going well. I used a Kester activ...

I always go to the web based mail server if it is available to see if the messages are being dropped from there. Also a great test is using these auto-responder sites. You send them an email, blank is fine but put something in the message subject box. Once received, they send back an acknowledgement...

As a follow up, the OEM support is abysmal! The tech guy maintains there is no battery, yet the factory specs show there is a battery backed up RAM, with expected 30 day life. He claims to 'change all the relays' in the units when they are rebuilt, but 'never saw any battery'. Original unit unavaila...

The vendor is supposed to be getting a 'refurb' unit together for the customer for $$$$, but I have seen several on ebay for +/- $200
So then, if that's the case would you expect that any of these PLC's of the same vintage will have the same issue?
Is his ship sinking?

Anyone out there familiar with the Telemecanique Modicon TSX Nano 07 series of logic controllers? This PLC is installed in a bindery machine and a few weeks ago it failed, error LED on, no activity. Their factory tech support gave a diagnosis that it was 'un-powered for too long'...? and the program...

Externet, I have been following this thread, and added a few comments, but the question now is... Why do you want to measure this minuscule magnetic field? I would think that the earth's much larger magnetic influence, and the clutter all else around this magnet's minor field, would swamp it complet...

Years ago it was purported that they could tell what was being typed on an IBM Selectric typewriter by the line current pulses from the motor related to the mechanical movements. After the enginers went the limits with filter and suppression ideas, some tech hung a flywheel on the motor shaft an the...

OK, Here's the deal Get an old CRT TV, place it near the magnet, use wireless linking of a video camera looking at the CRT screen to your remote location, and observe the color distortion caused by the magnet to confirm movement. Use a hall effect switch, and a siren on the roof. OR.. we could work ...
