Do I take it that the two small round nozzles are the dewalt SMD reheat nozzles  :-DD

No, they're for blowing up hot air baloons. :-+

Now I just have to wait for them to build it...

Got a parcel today from Toploser.......

The items I paid for, the Bourns pots and the peltier cooler units ( bare unsealed devices) plus some eztra packaging material in the carton to stop it rattling.

Cheaper than packing peanuts. so I got a few UV led units ( either UV or really royal blue, can't decide, so I will have to look at them further. Really nice die inside, with a gold top metal layer and gold bond wires as well, must pop one under the microscope), some IGBT devices ( nice!) and enough 0R1 SMD resistors to make a dummy load or hundred with.

Thanks Ian! I like your scrap packing material, a good mystery bonus there.

Well, microscope is right next to me, so a quickie for this then.

Thanks Ian, one of the nicest looking LED dies I have seen for a while.

I've got a thinkpad at work. Does your trackpad suck as much as mine ?

I have a T420s at home and the trackpad is perfectly fine.  Some coworkers at work have a T430, T530, and first get X1 carbon, all have decent trackpads.  I did get a T440 at work though with the unholy "clickpad" abomination they introduced last year...that thing is the worst pointing device I have ever used on a computer.  Apparently they received so many complaints that for 2015 they reverted the entire product line back to the traditional trackpad, so I don't expect any problems with this one.

Having had no income for 8 weeks now I have been unable to buy anything new, I did get given a intel D915G motherboard in a complete pc though for nothing, it seems the old owner couldnt get it to run, however when i ran it up and shoved spyhunter on it it found some 1018 infected files ... Oh well. I now have an old P4 machine that has a parallel and serial port so that was a bonus for some old hardware I wanted to build. I also now have a spare ATX psu for conversion.

I got one of those recently. I like it a lot.

Mine works great. Better than the one on my old HP laptop.

I just love Lenovo Notebooks for my engineering stuff.
Some CAD programs run faster on my W520 than on big tower workstations.
They are just amazing.

But I never owned an X1 Carbon
Will you be running it for engineering purposes?
May be you can share your experiences

Got a set of six 350 Farad 2.7V ultracapacitors to attach across the car battery to give the 5 litre V8 a bit more of a shove when starting, particularly on cold mornings. You can even start the car without a battery, just using the caps only, but a battery + cap combo is the ideal setup. Even if the battery is so cold, old or sad that the starter solenoid just chatters, one of these fitted will make it crank over like a new battery.

It will be used for general purpose everything.

My current "lab machine/server" will be moved to dedicated server-only duty, my current general purpose T420s will move to lab duty, and the X1 Carbon will take the place of the T420s.  It'll mostly be kicad, programming, general on-site equipment testing/debugging, etc.  The first thing I'm going to do when I get it is wipe it and install OpenSUSE Tumbleweed, then I'll probably stick Windows 10 in a VM for the tasks that still require Windows.

Unfortunately Lenovo just pushed the estimated ship date back 10 days to July 17, so who knows when it'll get here.  Hopefully it shows up before my trip to Peru in August, I could use it on that long flight.

Hi

I got the R6144 two weeks ago, seller said it was noisy and it is, the LT1021-7 is giving up the ghost, waiting for a replacement.

The 199 I got today, apparently powers up but not tested, but it didn't. One of the primary side coils on the main transformer was open, where the PCB pin meets the wire. Fixed that and now it just reads garbage. Probably sumpthing in the ADC.

Bonus the longest boge wire I have seen

Hi,

I also get few UV LEDs from Ian. Maybe we can use them for an small PCB UV exposure box?

Cheers,
Damir

Would these outlast the battery if permanently attached or would you have to keep them separate and only use when necessary?

Interesting....
Can you show a picture of the other side with the balancing circuit?
How is the balancing solved for these Maxwell capacitors?
Where did you buy the unit of the PCB?
How did you interface the heavy cables to the PCB?

A box of NOS adjustable 15W power resistors.
1984 vintage, look nice...
And that's all they do, unfortunately.

Specced at 1.5Ohm, +-5% they actually read 5.1 Ohm.
Also, the tweaker does not really work - there is no contact most of the time even after cleaning the resistive wire of corrosion.
They seem to all have about the same wrong resistance, so either i understand the labelling wrong (1.5 Ohm resistor. How can it mean 5.1 Ohm? Did they print the digits in the wrong order?), or they have degraded over time.

Well, back to looking for a tweakable 0.41 Ohm sense resistor in the 5W range...

I'd expect them to last for many years provided you don't let them get way too hot. Keep them across the battery permanently. Have a search on YouTube.

Thanks, will be interesting to see, how the balancing was solved on this PCB.

If you scroll down there is a full schematic.  It looks like they have used a combination of light emitting and normal diodes to get something a little below the 2.7V max of each cap.
