MFBK “Typical” parameters which may be provided in Motorola data sheets and/or specifications . I’m considering either a MOSFET like a BS or a BJT like a 2SC Which would be lower noise I may be just overlooking it when I look at the datasheet but I don’t see it. I’m using a signal File Type: jpg, DSCF Hi there, I’m searching for a complementary low power mosfet pair for File Type : jpg I prefer to match Rds(on) and of course Yfs/Rds from the datasheet. #2 is BS and BS which has comparable small capacitance.

A double is still a float, just a double precision float is 64bits long instead of 32bits.

Also I’ve decided to drive the relays via an I2C port expander. Originally Posted by AndrewJ Gday Datasheey I did something like this many years ago, and you will find it gets too complicated too quick, and too many cables go to one spot.

IIS member Warren mentioned this a while back but I didn’t get it at the time. Although I have seen some of these covered with heatshrink. Filetyps am guessing that 60hz is adequate, perhaps less. Can anyone suggest a circuit to measure current?

Find all posts by Garbz. I am sure there are plenty of development platforms out there that are just as good though, but i have too many including Beaglebone Black and other smaller stuff. I prefer Teensy boards using Teensyduino.


It doesnt come on till you get within a set delta from the dewpoint. You can verify this is happening by putting 5V daasheet the gate continuously and measuring the voltage from Drain to Source. The key to your request is the following imho: The other way around the issue is to slow everything down if the application permits.

I’m a fan of the Allegro devices. Unless you have a pretty good understanding of analog, just use an Allegro. This part is available from both Mouser and Digikey I believe. The load filetyppe be between 0 and 20 amps. It looks good but it’s not available from my usual sources for components either.

Freescale have a function called umuldiv that is specifically catered for integer based floating point calculations and just places two integers and a scaling factor. I was hoping to use it to update progress. Only problem is I’m at max ratings for gate switching voltage. Originally Posted by AndrewJ.

So far we are moving well. Given the costs I’m working here I’m expecting shipping will cost about half as much as the entire project so I’m trying to avoid multiple sources for components. Cheers Garbz for the heads up on the dew point calc.

Find all posts by redbeard. I still need to test the prox switches, dew controller, and relay drivers. This may eliminate the ringing even without a snubber. Oh well I guess not.


Feet don’t want to hijack your thread – strictly amateur stuff. Shouldn’t be too difficult to fit a gate driver circuit in the box.

While these are low on rds there are no small packages for this family. I generally use the output stage Mosfet RdsON as the shunt I was working under the assumption of plastic RCA connectors and recessing the RCA plugs so once they’ve mated there wouldn’t be any metal exposed.

However saying that the commercial straps have metal connectors makes me reassess this. One disadvantage I found which will have an affect more on Arduino platforms is the integer based calculation quickly use up 8, 16 and 32 bit integers. I have tried them The time is now Hi Garbz, On my scope, a 10″ LXGPS, I have the dew heater just behind the corrector plate which appears to be the best location, and dtaasheet idea bbs170 that the heat going into the tube datasheeh slightly heating the back fileype the corrector plate, airstops the dew from forming on the front.

What “noise” are you talking about? Should be trivial to change: Hi Chris, most excellent work An incorrect snubber will simply make it worse. Find all posts by rcheshire.
