DSO138 Oscilloscope DIY Kit

Just a quick post to show a new gadget I put together. The DSO138 Digital Oscilloscope.

It comes as a do-it-yourself kit and is priced very inexpensive. I got mine on eBay for $30 shipped, including the case. Not bad!

"DSO138 was designed as a training oscilloscope kit. It contains only the basical oscilloscope functions with no fancy features. Simplicity in structure and easiness in assembly/operation are among the main targets of the design. For these purpose DSO138 uses mostly through-hole parts. The heart of DSO138 is a Cortex-M3 ARM processor (STM32F103C8) from ST. It uses 2.4-inch TFT LCD (320 X 240 dotmatrix, 262K colors) as its display element and displays nice and clear waveforms. Detailed assembly instructions are provided in combination with troubleshooting guide and schematc. Source codes are also available to allow user to add their own features." - JYE Tech

I don't know much about Oscilloscopes, so I thought this might be a way I could tinker with one easily and have a project to put together. My kit was missing 1 resistor which I didn't have available, but the eBay seller was quick to remedy that. Assembly took me about 2 hours and maybe 30min-1hr for the case. It came with a nice color assembly sheet and instruction card with photos, which made it pretty easy. The resistors weren't labeled, so I spent most of that time metering values and sorting parts.

If you have any interest in this type of thing, maybe this is the kit for you! Here are some links that might help you along the way:
