I was having a read through the K Mon thread and it seems people like Guilt Toy and a few others are a step ahead with "reliable" power supplies for Lap Tops .

Just today I was looking at inverters at my local Jaycar outlet and they carry two kinds of Digitech units in a range of outputs ie 150/300/400w - thats the modified sine wave type , and 150/380w etc in the pure sine wave type .

I gather the pure sine wave type is better but I'm not sure which wattage level is the go and what 240AC devices that say the 380w one could run .

Also I'd like to know more about the 12v 12v power pack device as well .

Cheers and thanks , A .

If your laptop is has a common power plug on it (ie not the dell square connector) you are better off getting a 12v converter that just plugs into the cigarette lighter as you will generally find they are cheaper than getting a decent 12v > 240v inverter that wont introduce lots of signal noise. Check out the jaycar ones as they offer a few different options at fairly good prices.

My lap tops AC adapter "brick" (67x36x165) reckons its output is 20V 5a and it gets very warm .

Is a 12v 12v gasper adapter going to run this thing ?

Actually I've just checked out the AC adapters on the other two LT's in this joint and they are 19v 3.5a and 15v 2a . ? .

Yeah the pure sine wave Digitech 380w rated 240v AC inverter is ~ $240 .

What else would it be able to feed - 380 watt ?

Cheers A .

Just back from Jaycar again , they can't supply a DC DC adapter to feed this lap top 5 amps . Up to 3.5 amps only .

They suggest that I see Hardley Normals and their best offering was a white AC and DC fed charger - for $199 ...

No chance .

Any ideas ?

I use the 150w digitech without drama. $48

i bought the same one, my lappy seems to disagree with it though.

the converter only turns on for short "bursts" once every 5 seconds or so...

You have to remember that you are talking about peak power, power usage depends on CPU usage rate, your laptop won't use 5.5 amps continuously. Things like burning CD/DVD, huge data set manipulation etc will have a high power usage. We use 150 watts units for work all the time and they never run out. I can plug my dead flat laptop in, boot it up, and use it to download big [but simple] data files from loggers [try a weather station with approx 10 parameters logged every 10 minutes for two months] and it does it easily.

I'm with Adriano and co, you will be fine with the $48 special.

I'll see if Jaycar still do that 5.5 - 6a DC power supply , fella may not have known about them if he's new or was not in stock .

All this BS is over using a dated lap top with a serial port and it only wants to work on battery power and the Datalogit few a few moments - no matter how long it's charged for .

It can play a DVD movie for nearly 40 min on battery power but caves in very quickly with the Datalogit .

Am I to assume that the Datalogit has high power demands through its serial port or is it some other weird electronic glitch ? This is using the Datalogit with the supplied USB serial converter BTW ...

Yes I can hear the thoughts - why is he bothering with serial ports and not using them ?

If that USB converter dies (and they can at times) your stuffed if you don't have the RS232 serial port .

Cheers A .

Disco, with that sort of power drain, I'd be thinking that the laptop is also using the RS232 looking for a printer at the same time, burning up power trying, so you get conflicting issues. If you do use the USB is the power usage better? I'd have to say would be.

All I have used is the supplied USB/serial converter cable so far meaning USB at the lap top end .

I've stuck the missuses Toshiba 3.95a / AC power adapter into this thing to see what will happen - sky didn't fall in so cig powered 3.5a DC adapter should work ok provided the cars socket still works .

BTW I was thinking of using the socket to power the Tech Edge WB02 , is the socket going to carry it and lap top or do I really need a dedicated power supply ?

Cheers and thanks , A .

Problem solved , Jaycar DO still sell a higher powered DC auto lap top power adapter .

It's called a Power Tech Plus MP-3472 Auto Lap top Power Supply 150w .

It lets you select 15 or 16V 8.5a regulated - 18 or 19V 8a regulated - 20v 7.5a regulated - 22V 6.5a regulated - 24V 6a regulated - 150w max . Damage is $59.99 .

It's socket plug has a 15a blade fuse in it and the kit includes 9 different replaceable plugs to fit various lap tops power sockets inc a weird looking Hewlet Packard one .

Will give it a go tomorrow , cheers A .

    • Yeah, plenty of air flow, there is a dedicated path that feeds the air in to the OEM intake tube behind the bumper As for a "tangible effect", maybe, but getting the pod/intake air out of the hot engine bay is worth it psychologically to me, even if it gives no performance difference, so the tangible effect in my Lizard brain saysss yessss  In the end, to me a tangible effect isn't always about performance, sometimes it a sound or a look, or even a...... feeling  Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga
    • yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching
    • Quite right, if you make it to that pension you deserve every cent
    • Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!
    • From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.
