What did you buy today? Post your latest purchase!

I'm very envious. Working turbos _with_ matching controllers are almost impossible to come by.

Dozens of them were auctioned earlier this year after the bankruptcy of Mapper.
But I had no idea what to do with them so passed on them. Dont even know how to do metal disposition etc.
Is that something you can do at home ? Dont you need a cleanroom? What will you do with it? 

However I bought a Edwards XDS35i  industrial vacuum pump that already had 26000 hrs on it (found out later after pickup) still would go just over $900. New thry are in the $20k i believe. A simple gasket replacement set will set me back $700 so I hope it will last me a few years. It works but also had no caps on the input output.
I have to find some matching hose and adapters and a decent prefilter is necessary i believe. The thing can only go from room pressure to 10mbar five times an hour but can run all day long at 10 mbar , weird devices 
I want to use that one for a diy p&p machine and vacuum table for my cnc mill, I know way overkill but fun.

And the sad thing is that Agilent still probably won't give you a job. Turns out they aren't real big fans of tinkerers, or PhD's for that matter. Apparently we're 'too ambitious'. Hopefully the postdoc situation in your country is better than it is in Australia.

Oh hi Iso, you're here!

Yes I am! I do lurk around here to see how the various projects are progressing, good to see when you have some new posts. I should write more often, sorry...

 The flanges on it are called KFXX flanges, xx being dimensions of tubing in mm. You can get flange to hose barb adapters dirt cheap on the ebay! 
I wouldn't worry about filters for low-crit applications like this.

Metal deposition is certainly possible without a clean room!
Question is just how decent results are. Worst case, making a "clean room bag" glove box full of dry nitrogen coupled to the vacuum chamber inlet as a clean prepping/cleaning zone might do the trick! I'll def. Try.

Wished I had this device earlier this evening to keep my barman honest. The Bourbon and Cokes seemed to taste a little too sugary.

Fixed a canine related issue today.  The Dumberman (dumb Doberman) keeps knocking the surge protector hung on the front of the workbench off its screws with the weapon of mass destruction that is his tail.   Finally went to the big box hardware store and got a metal 2 gang outlet box, 2 outlets, a wall plate and a male plug as I have a bunch of 14 ga 3 wire left from a bad extension cord.  The box is screwed down tight with multiple screw on the frame of the bench.  Let him knock that off.

Ok , curious what you are going to build with it, ic's ?

[ChristofferB]

Actually the project I'm doing at university is large macrocyclic molecules that are candidates for organic semiconductors and LEDs. Would be cool to be able to demonstrate that.

Ok that is way past the 1yr Uni chemistry knowledge from 30 yrs ago I have
But if you get something that glows or can be shown, would love to see it posted.
Good luck

Dell D830 at a whopping 2.4ghz dual core and 3 GB ram. 70$ so not too bad.

I used a D620 and a bit later switched to a D630, but several friends had the D820 and D830. I loved these computers - they were built to last. Their only major drawback was that Nvidia chipset that had premature failures due to its flip chip packaging

I scored a brand new DSOX1204a with 100Mhz BW and all software options for $500 on eBay.  No probes included though...

That's quite a good deal. They're rather sweet little oscilloscopes.

[bitseeker]

That is a good deal. Nicely done.

I bought a rather nice looking monitor arm so I can get the 28” lcd off the desk and give me more space for my workbench.

Rather a good price for thrm from Fleabay. Straight from Invision.

Looks a nice bit of kit, gas ram in the arm and adjustable load.

A loaf of bread, and no, I won't post a photo.

It seems pretty solid. I cloned the drive to an SSD and made sure it worked then I stripped it down. Cleaned everything and it's nearly like new but I'm still waiting on the bluetooth module and flash cache module so it's still in pieces. The fan runs all the time the nvidia chip has underfill and a heat pipe on it with thermal compound so I think it'll be ok.

Great deal on a great scope - congrats!

I bought a HP85662A for 90 euros from France (+ shipping 85 euros ).
Apparently the unit is working fine but the CRT is dim, I plan to replace it with the LCD retrofit NewScope-8 from Simmconn Labs : http://www.simmconnlabs.com/1401/2564.html

Hi, I recognize the seller's pictures (F1*****), I bought from him once.
The shipping is always high, but the parcels are rock solid and the equipment is very well protected.

Is that the seller with the stupid prices for ancient crap? They refused my overly enthusiastic offer once, four months later they were still trying to push it for significantly less. Luckily I had come to my senses and scored better kit for less.

[richnormand]

Just got these two Symmetricom 58502A.
Perfect condition.
Will be used with GPSO primary and rubidium clock secondary to distribute the 10MHz ref to the bench instruments.

I've bought from him at least once before, the pricing is a little random, but once in a while he does have some decent deals.
Anyway we don't have that much choice over here.
His packing is done very professionally with injected polyurethane foam.
