Please pass the popcorn. This is getting interesting.
Nah, I'm done. Right, wrong, who cares? I said what I believe. Either folks "get it", or they don't. Either they agree or they probably never will.

I don’t want to screw up Bob’s revenue stream, I don’t want to stifle Rick’s ability to come up with and discuss good products, either. What I WANT is for the Rickster to show he’s a good guy. Worthy of doing business with. Whether he chooses to or not is now his choice alone.

Hello everyone,

Greg, thats exactly what it does. It has high current FETs that are driven by the signal from the receiver. The MPU just handles the change in direction.

Rick, I’m electronically challenged. I’ve read both your missives here, and I still have no idea what this widget does. Can you type slowly so I have a chance of understanding?

Steve - It’s basically a amplifier. Like any amplifier, it is driven by a small signal and delivers a large signal. In this case, the booster is taking the battery power, and delivering to the motors with more current than the decoder alone could.

Jon, this is good because…?

Like Rick said - if you pull too much current from the decoder alone, it thermally shuts down, or worse releases the magic smoke. Most locos wouldn’t need it, but if you want to run three honkin’ diesels from one decoder it would help.

#25

Where do the extra 'trons come from?

Or is it magic?

#26

What is this, electricity 101 ??? From the battery.

#27

Steve, think of it as working like a fancy relay. A smaller current (through the decoder) opens a bigger switch… just like the two circuits of a car relay, the ‘trons’ all come from the battery

I told you I was challenged. I'll accept magic. :P

Do you understand water, pipes and valves ?

If you said yes, then you understand electricity too.

Rick, My facts are this: When I have my few meagre hobby dollars to spend. I turn first to the vendors that I've come to know and like through their participation in the forums. If their price is reasonable (and it usually is). I don't look further. Whether they 'sponsor' the forum or not.

Your past behaviors on several forums have given me little reason to either like or trust you. Your product may be quality, or your prices good. But you aren’t going to get on my preferred vendor short list by JUST that. If nothing else, consider amiable participation as simply good advertising – with a better long term return than simply spending a few sheckles for a banner ad. And it will possibly even improve your communication skills. If you’re too busy with your businesses for that, then you probably don’t need my money.

Like it or not, the threads I remember most by you were the one where you split hairs insisting you had the ‘right’ to use a name that you declined to purchase and trying to push an owner to sell the board he had declined to sell. That’s a pretty deep negative hole that you got into all by yourself. Would you like to stop digging now?


Sure looks like the Pot calling the Kettle black again…

Waa Waa Waa…

Don’t worry Nicky, I wouldn’t buy off you either. I occasionally wish your snide, smart ass attitude hurt you as much as everyone else.

I’d still like to know how long the two PnP pins that carry 12 amps output load are going to last before they melt.
When Lewis Polk looked into just such improvements a few years ago, before Mr Isard appeared on the scene, he discovered that the most current even the best quality ones could carry, was 5 amps.
Another load question.
Obviously I don’t know for sure as I haven’t seen the circuit so I could be wrong, but they look like 3 amp diodes in a bridge layout on the booster board. If they are on the battery input circuit, could Mr Isard explain how 3 amp diodes can carry 12 amps please?

#34

Mik, just do like everone else does, and ignore him. :wink:

Mik, Rick is an advertiser here. As such, he helps support your "free" ride. Maybe you should give that a little consideration. Ralph
You might also wish to reconsider your 'free ride' comment in light of me being the one organizing the challenges AND paying for the prizes out of my own pocket. Neither the prizes, nor the postage, are "free". If those don't add anything of value to the board, then I won't bother doing any more.
Mik, I've done the same with the Challenge. And we both "contribute" frequently to the editorial mix. Advertisers such as Rick help Bob pay the bills so WE don't have to PAY to participate. Maybe I should have said "our free ride", as there was no intent to imply that you were a "freeloader". Thanks to Bob and his advertisers, NONE of US has to pay to participate. Ralph

Funny - When I do a search for “RailLinx”, I can’t find anything other than this thread and these …

Well at least i can now buy a Quality built AMERICAN

RCS system…

Food on the table Mr Tuna, Food on the table… HA.

Keep up the good work Rick.

I asked if Mr Isard ever posted anything that wasn't a self-serving sales pitch. The answer to that seems to be "no". Having acquired that bit of information, I can now safely ignore everything he posts. If you don't like my projects, or me, feel free to do the same.
If your so knowledgeable perhaps you should have heeded you own GREAT words ?

Standard 3M .1" spacing header pins are rated for 3 amps.

Rick, I would like to know more. There are no heat sinks on the QSI unit, and while the output transistors are rated up around 5 amps I believe, there is just no way to dissipate the heat.

Can you go into some more detail about the output power capability? I realize that this is probably on your site, but this could be a very nice option for people who use a lot of QSI like me, and in cases where the motors can draw a lot of current, like pittmans, as well as of course running 2 locos from one unit.

I went to your site, cannot find any “read more” from the link.

You might want to consider some “take off’s” on the board to feed the motor output to another loco, that would help mitigate the max current restriction on the pins, at least the motors. If you added “input” pins, then I think you would overcome any problems where people were running max output.

All: I think Rick said 12 amp “stall” which normally is not continuous duty.

Regards, Greg
