Rotary encoder on wrong side of PCB

From the FAQ, it seems I've soldered the rotary encoder on the wrong side of the PCB. Values always increase and I've to boot again the DSO Shell to start from low values. I've just checked the documentation that is available on the DSO Shell product page http://www.jyetech.com/Products/LcdScope/Use...

Re: Overvoltage. What next?

I've received the replacement analog card and built it yesterday. Now with a brand new switched power supply too, voltages conform to the expected values:

Input: 9.16 V
V+: 8.21 V
AV+: 6.79 V
V-: -7.41 V
AV-: -6.08 V
V1: 0 V
V2: 0 V
V3: 0 V
V4: 1.49 V
V5: -1.02 V
V6: 6.12 V

Re: Beginner -should I get a DSO shell?

I just killed my DSO when supplying it with 16.5 V from a non-regulated power supply. I should have read this thread before starting the assembly.

Lesson: always test; don't trust specs!

Overvoltage. What next?

Hello, Everything was going fine with soldering the DSO SHELL when I did one fatal mistake. I did not test the output voltage of the brand new 9V power supply I had bought the previous day. I measured the voltage control points and they were not far from the expected values. So I continued to next s...
