Lenovo Thinkpad X1 Carbon 3rd gen
8GB RAM, i5-5300U, 512GB PCIe x4 SSD, 2.9 lbs and 11 hour battery life
Now I just have to wait for them to build it...
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
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.

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.
Just scored three 3457 7-1/2 digit meters for 165$ each ...
i also acquired 7 ( yes SEVEN ) U8001 power supplies for a ridiculous price....

It seems you have been at the right spot at the right time again!
Pictures?
Some new keycaps for my das and Nextion came today
I've just bought another incomplete HP8510B 20GHz VNA.

It arrived today. It feels very well built, small, and incredibly light. First thing I did when I got it was backup the restore partition and then wipe the drive and install Linux, then install Windows 7 in a VM. Everything is working out of the box, no hiccups. The processor is nothing to write home about, Intel hasn't really improved processing power versus the standard notebook processors from 3 years ago, but what they have done is cut the power requirements of the processor in half and improved the graphics capabilities. So same processing power as a few years ago, but better graphics and significantly lower power. In addition to the improved battery life this gives, it also means the machine runs cool and quiet regardless of what you're doing on it. It's spent the last 2 hours with the CPU running 100% (Windows updates) and you can hardly hear the fan and it's barely warm to the touch.
The PCIe x4 drive is SUPER fast too, I got an average of 1.3 GB/s write and 1.1 GB/s read on a 50 GB dd dump, WHILE simultaneously installing a program on Linux, doing system updates on the Win 7 VM, and installing two programs on the Win 7 VM.
I'm happy with it, it should be a very nice machine for my uses. I just wish they offered a 16 GB RAM option for it...
I bought a Hakko FX-951, some cartridges and cartridge sleeves and an extra brass curl from TEquipment.net. The order is marked ship complete only. I have a cartridge arriving tomorrow that shipped on the 14th when I ordered everything. Supposedly 4 more pieces were to have shipped yesterday. 6 pieces are shipping tomorrow and the final cartridge will be shipped on the 22nd. Methinks they are losing money here on the shipping.

They have multiple warehouses, so if the order has to be filled from more than one, your order will show up in multiple packages (and don't always arrive on the same day). Ordering something not in stock can cause this as well.
FWIW, I ran into both situations.
I got me a BK 2120 today for $40! I've got a couple of Rigol scopes, but I've always wanted an analog one to mess around with. This one is super clean, I even did the Dave "take it apart" to see if it needed a blow out with compressed air and it looks super clean on the inside too.
That takes me back to my ITT Technical Institute days. We used BK 20 MHz scopes, I don't remember the model number but yours looks just like what I used. Enjoy your find.
