There's a typo in the code line 128

text = String("0223456789")[number % 10] + text;

should be 

text = String("0123456789")[number % 10] + text;

Distribution 206 fixes this, to be found on the leading post of the thread.

I sampled some of these after @@oPossum did a project with them. Do you know if these accurately measure uA range or are they not well suited for it?

Could be the basis of another PowerScope...

 

 

edit: Nevermind, it depends on the current shunt resistor you use, forgot that you had to supply that :D

That's an interesting project!
 
According to the specification sheet, ADC Basic Resolution is 1 LSB Step Size = 10 ?V for the Shunt Voltage, obviously to be combined with the shunt resistor for the ?A accuracy.

 

The INA219 supports the transmission protocol for fast (1kHz to 400kHz) and high-speed (1kHz to 3.4MHz) modes.

This link appears to generate a random web lookup; I've gotten a list of local banks and a pseudo news article advising me to invest in Biozoom, who apparently have successfully created a medical tricorder.

Hmm.. the page won't open now. @@Rei Vilo Can you fix it.

The pitch is 0.050" or 1.27mm so it's doable.

 

There are many tutorials about how to solder SMD, but it appears each one has his/hers own way of proceeding.

 

To practice, you can buy a cheap kit with SMD like this one to learn.

This is how I learnt soldering SMD, actually discovering it was easier than expected.

 

Don't be afraid to use binoculars :)
