Data logging, could a Cheap open source DSO oscilloscope be a nice tool for flashlight measurements?

Flashlight Modding and DIY Parts

I am looking for a bugdget solution data logging device for making some measurements on my flashlights and batteries.

I found a <90USD Digital oscilloscope which looks like a perfect tool for measuring flashlights.

DSO Nano v2 is a Digital Storage Oscilloscope designed for basic electronic engineering tasks. Within its smart shell, the device runs on ARM Cortex™-M3 32 bit platform, provides basic waveform monitoring with extensive functions. It equips 320*240 color LCD, micro SD card storage, portable probes, LiPo Battery, USB connection and signal generator. Due to palm size and handy performance, it fits in-field diagnosis, quick measurement, hobbyist projects and wherever convenience matters. Scheme and source files are also open for re-innovating.
The hardware seems perfect, but the open source SW needs to be adjusted to a slower "data-logging mode "
The problem is that i have no programming skills.
Does any of you have any other idea of a "budget logger" maybe based on a cheap Arduino board?

Personally I believe that a DMM with data output is better for logging when measuring on flashlights. The main reason is resolution, most oscilloscopes has a range of 0..255 or -128..127, with even the cheapest DMM you get a -2000..+2000 range.

The largest disadvantage with DMM's is batteries, you have to replace them often when using it for logging, rechargeable reduces the cost, but not the inconvenience.
