You might want to check online if you'll need ear plugs, safety glasses, a hard hat and a vest.

Not to mention gloves, boots and scba.

And a paramedic...

Hi, just got a XDRduino MEGA 2560 R3, that I bidded for on ebay, $15.00 Australian, the controller board, nice stack of jumpers for  protobaorad and a 64 x 10 protoboard (with isolated bit in middle of power bus down each side) and a 5V/3.3V power board the mounts on the end of the protoboard.

Got to find time to play with it now.....

Digital calipers.... which interestingly shows on the invoice as a vernier. Seems folk think the measuring instrument itself is called the vernier, whereas those of us in the know know that the vernier is the two-sided misaligning sliding scale thingy that gives us the decimals.

Also a pack of atTinies: no real use for them but just want to make a device which isn't actually wired to my Uno, just for the heck of it.

(I wonder if the adafruit oled library will fit in there....)

Same reason I got a few nano and bareduino kits.

Well to get this thread back on subject, here is a very cool thing I picked up on E-bay a couple of weeks ago. It's a 328P based component tester that really is a useful piece of test equipment. It uses a simple 9 volt batter for power with auto turn-off for long battery life.

 So while a decent DMM is still the first peice of test equipment a begineer should get, this could very well be the second best thing to get. If you have any questions let me know.

That is a cool gizmo!
How well do the measured results fit the expected values?

And a kick-ass bag of random caps for R20... 1.90USD, 1.40EUR, 1.10GBP

Edit: Heaven knows how old and leaky these must be, not one so far has measured at the marked value. Some use the old "MFD" measure for the current "µF" style, so I wonder how old they are?

 I only had a precision resistor to check accuracy with at the moment. My 0.05% 250 ohm precision resistor measured 250.5 ohms on the unit, so pretty good. I need to find a precision cap to check that function.

Hi, I have a version of that meter and at my workplace we have two. Bought as an assembled PCB and we had to put them in a case.
They have to be one of the most used bits of gear we have, second only to DMM.
Accuracy is about 3 to 5% in most cases, but I like its semiconductor features, identifying devices, BJT, FET, Dual Diode, Diode, measuring Resistor, Inductance and Capacitance, and the main reason we bought them, ESR.
Also the ones that we have tell you the 9V battery voltage on start up.

SMPS capacitor testing is no problem, and cheaper than the PEAK devices.

Below is the one I bought. The use of a ZIF socket for attaching components or extension leads is really user friendly. I think any hobbyist should jump on these devices. Most bang for the buck I've seen in years.
