MediaTester can test any media (SD, microSD, thumb, etc) and verify it stores the expected number of bytes. The testing method is similar to h2testw but MediaTester can detect fake or defective media much faster by performing quick reads as data is written. If you buy any storage media, use MediaTester to verify it or risk losing your data.

(Please see debug branch, it will be merged to master soon) Microcontroller-based batch audio presenter which I have developed during my postdoc in cognitive neuroscience at CerCo/Toulouse. If you construct one and flash it with the software here, this device should serve your realtime audio presentation needs sync'd with an EEG amp, especially if you're very concerned with jitter.
