My friend poo poo'd the ESD claim, need to be black coated not stainless steel. I guess wrist strap required.
I just bought this air compressor.
8 bar, 2L tank (no oil), 1100W, 1,5 hp, 195 l/min.
It is really loud, but useful when I need to remove dust from some old dirty, dusty and sometimes crusty boards, fans, computer cases.
I paid around 120 euros, it may be a lot, but now I don't need all tiny - and too expensive - air dusters (aerosol sprays).
It's not that expensive if you consider that a can of Air-duster will cost about €10, so 12 cans (a years worth in my world) costs the same. So after 12 months you're saving money.

Some goods arrived today:) HP 34401 for 180EUR and something for my cnc mill.
I recently did some math on how much modern computers cost, and the conclusion was kinda absurd.
Supposedly, i could get a computer than would be 0.75x as fast as my current $2000 rig from 2009 for just 0.02x the cost.
Naturally, i couldn't quite believe it and went looking for a catch.
Didn't find any, and ended up with 4 computers' worth of cheapest second hand components i could find, and some spare cash missing.
Ended up making a nice box for them, which triples the computing power i have at home.

It's really bizarre to look at one of these boards with a meter showing 1.7A (at 12V) doing in near silence almost as good as the roaring monster nearby taking about 150W.
F-ing Moore's law.
Where did you get LGA1155 mini-ITX for $40 ($2000 * 0.02) with some sensible IvyBridge CPU?, RAM and so on?
I wouldn't expect much raw computing power from your setup. It is cluster like, IO severely limited by the gigabit ethernet (!= InfiniBand) and it is CPU only.
If I might ask where did the boards come from?
The nice thing about second hand computer parts is that they work exactly as good, but cost a half to a third of the new one.
That's a nice looking instrument and being Japanese you can rest assured that the quality will be good. Perfect for finding short circuits on PC boards etc.
Nice meter. It looks brand new, so I suppose no mini-teardown to look under the cover?
I'm looking on ebay for Keithley 580, but somehow these things go for crazy prices. This Hioki looks nice, but it is even more expensive
BTW, this meter is not that expensive as you think, it took me 83,000JPY, cuz it had been listed as "for parts or repair"
BTW, this meter is not that expensive as you think, it took me 83,000JPY, cuz it had been listed as "for parts or repair"You got a really good deal on this meter.
It has some amazing specs:
0.01 µ? to 1.200 G?. RS-232C, RS-232C Printer, USB, and GPIB interfaces.
Can perform resistance measurement with a 6.5-digit, 1,200,000-count display at a maximum resolution of 0.01 ??. It delivers more than enough capabilities to be used in applications requiring high-resolution resistance measurement, for example in testing inverter motor windings.
High-resistance materials such as conductive sheets and conductive rubber are often used in electronic components. The RM3545 can measure resistance values of up to 1,200 M?. It also delivers maximum accuracy of 0.006%, enabling researchers to test state-of-the-art current sensing resistors.
Auto-scanning and step scanning
When using the Multiplexer Unit Z3003 to perform scanning measurement, you can select either step scanning or auto scanning depending on the test conditions. Auto scanning is convenient when you require only an overall judgment result at the completion of scanning, while step scanning is convenient when you wish to generate judgments in real time using the instrument’s EXT I/O interface.
Congratulations.
83000 Japanese Yen equals 1047.929 Australian Dollar.
And you bought for parts at that price?
Picked up two packages from Aliexpress today (import taxes destroyed my wallet this time, Brazil)
A ceramic and electrolytic capacitor kit, lil trimmer kit and a rip-off Mastech multimeter.
