Re: AM dust filters
One important question: how often is the equipment accessed for maintenance? I've had reasonably good luck with air filter media coated with a tackifier, similar to the Dustlok media here http://www.filtersales.com/pagout.htm?id=Pad%20Media It seems like what happens with it is heavier airborne fibers (lint, hair) get caught up in the first few fibers of the media, not obstructing airflow, and allow the finer dust to travel deeper into the media where it sticks to the tacky layer at the back. It lasts a good long while. It's single use though, so it has to be replenlished every now and then. Foam rubber media tends to have trouble with surface/airflow area vs pore size. The best option, though, will be to enclose the equipment in a cabinet that can be pressurized by one or more fan forced+filtered inlets. Middle Atlantic makes rack cabinets and fan panels that can be used to pressurize them that way. If you get a cabinet that takes a standard furnace filter, I've had good luck with the off the shelf 3M Filtrete Ultra Allergen filters, they have a TON of surface area with great fine dust capture and very low airflow resistance, even when you're drawing the air through them really way too fast. :) On Tue, Aug 12, 2014 at 2:19 PM, Jason Lixfeld ja...@lixfeld.ca wrote: Hi, I'm interested in knowing what sorts of material folks use to make after-market dust filters for their various devices which wouldn't normally have any.

A material that is too dense will hider airflow and cause an immediate increase in inlet temperature, which would exacerbate a potentially threatening temperature situation in environments where the ambient temperature is already in the mid to high twenties and above (that's 77 - 86F+ for my American friends ;)).

Thanks, Tony All I meant was that the tools are relatively accessible to anyone with the desire to look - An oscilloscope with the necessary freq. range to study 4G communications can be bought or fabricated (all that's really needed is a microcontroller with an ADC, some gain amps and time), an appropriate SDR to intercept the signals shouldn't be too hard to source, and that community has been blowing up for a few years now.

Re: why haven't ethernet connectors changed?
I'm going to go by the Necessity is the mother of invention theory here and say that it's basically because the need for a subcompact ethernet connector hasn't shown up in masse yet. It was probably just adopted because it's inexpensive, easy to install using tools already out there in the telecom world, and it works well enough at the required feedline impedance of 100 ohms. That being said, any connector that works for balanced line signalling with a feedline impedance of 100 ohms and a favorable frequency response up to 100mc (100base-T / cat5) or 250mc (1000baseT / cat6) should work just fine. For obvious reasons, standardization of the submini ethernet connector should be present industrywide, so you don't have to start carrying around adapters.

RE: Eaton 9130 UPS feedback
Yeah, that's about right. When I had one fail that was not set in power saver mode, it just shut off intermittently before letting out the genie. When I had one go out while it was in energy saver mode, it continued to operate but put out a weak ~80Vrms with heavy distortion that caused equipment damage. Foul. Also in regards to OutBack - the Radian GS8048 is beautiful. I'd highly recommend it. It is basically two inverter/charger modules paralleled in one chassis, each being 4Kw. I was playing with one and yoinked the control cable to one module -- the power stayed on without incident and the MATE3 control unit (which is fun and Ethernet equipped) reported the error. If you use the 8048 in half capacity it's redundant. It gives 120/240 (l1, neutral, l2) out of the box and is pure sine. I recommend getting the matching GS load center with it because it makes the install super easy and includes the requisite breakers.
