Does anyone know of a rubber engineering forum that has engineers capable of understanding where this sticky substance originates and how it magically appears on all remote control units which have rubber keypads?

I mean the sticky goo that forms between the PCB and the bottom of the rubber switch membrane.. which has conductive pads that contact the PCB SMT patterns...... not the top of the rubber switch which contacts the finger tips.

What is that sticky goo that builds up on the rubber keys within a standard TV remote control? It gets on the PCB and causes conductive switch contact failure. Does anybody know of a remote control that uses standard metal dome switches so I don't have to replace my remote controls every 5 years.

Thanks danw, Do you know what the CJC on/off setting does? I don't understand why the TC accuracies get worse (according to the users manual) if CJC is enabled? Do you know if CJC is implemented automatically within the cheaper Fluke 725? (i.e. can I operate the 725 in outside temps of say...

I'm searching for a calibrator. I'm eyeing up either the Martel MC-1200 -or- Fluke 726 I like the MC-1200's keyboard, but, we all know the Fluke name. Does anyone have any comments on these units, or any other units, or any links to web pages offering reviews on calibrators.

Thanks waross. I thought there may be a trick. Do you know of any TC interfacing chips for sub-zero operation? (besides AD's stuff)

I'd like to use the Maxim MAX6674 thermocouple interface, but, I'd like to monitor temperatures less than 32degF. Has anyone used any tricks to run this interface 'below ground' and measure temperatures less than 0degC?

Can anyone post the link to the alleged IEEE DVD's containing 100s of patch designs? Can't seem to find how to purchase.

I'm new to patch antenna design. I'm trying to find out the best software to design 900 MHz F antenna's as well as some rectangular patches in 900 & 2.4G ISM bands. I downloaded (free) Sonnet and tried a 2.4 GHz patch design with it. It's 37.1x28.9mm with coax feed at 18.5 and 7.1mm. It's on...

These days, 2-4 years of experience gets you classified as a senior design engineer. I think I've spent more time in the bathroom.

I imagine variable cutoff analog -or- switched cap antialias filters on the front end of scopes may become commonplace soon.... then, we can chalk it up as progress. Until then, I usually go out to the fastest timebase and walk things back to determine what I'm looking at. Both HP and Tek are...

itsmoked, Your x10 markup from parts to product seems reasonable. Lets just say that all the firmware and VHDL for the FPGA's isn't free. I usually don't promote anybody's product, but, the Tek DPO4000 is quite impressive. No more triggering here and there... and dual timebase delaying with...

oops... I mean I have a THS720 ... not.. TDS720.

itsmoked, I too have a TDS720. Simply the best for field work. Fluke is trying hard with their color LCD handhelds, but, Tek has much better specs. For the lab bench, Just got a new 350MHz Tek DPO4034 deep memory scope with CAN demodulation option. It's hard to even consider turing on my old...

Try Maxim MAX618 and a digital pot like Analog Devices AD5231. I have a schematic if you want it for 5V to 20V @ 150ma as a reference.

I am looking for the cables that interconnect the HP 8568B Spectrum Analyzer RF section and the display. Does anybody know where I find them?

Oops... forgot... the problems are called "beancounters".

Still the same problems. They'll NEVER change... as opposed to the latin definition of 'engineer'.

Just put that MSEE diploma in the bedroom chest top drawer with the rest of your awards... like me... unless you've got an inferiority complex. If you don't create a new working, profitable design annually and/or haven't solved a differential equation in 1 year, you must relinquish your degrees...
