Oscilloscopes, for the most part, are large and expensive pieces of equipment. Given the usefulness of these devices, engineers and hackers are willing to give up a good chunk of desk space and cash to have one. For simple oscillicope functions, however, the OLEDiSCOPE fits in your hand and can measure voltages of up to 5DVC. It also costs under $23.95 plus shipping.
If this sounds incredible, apparently you’re not the only one, because as of this writing it is sold out. It should be noted that, though something like this can be useful, perhaps for audio measurement or working with PWM (pulse-width modulation) signals, it’s not going to replace something that costs hundreds of times as much.
The Phoenix Cnc, Olediuno store also has quite a few other gadgets for sale, several using the same type of tiny screen setup. This includes the very interesting and tiny spectrum analyzer seen in the video below. I could see this being used with any sort of audio streaming build for a hassle-free way to add a fun display element to your project.
