Flashcards for the Urdu-Nasta’līq script, made from the Wikipedia alphabet chart. As common Urdu is quite the same as Hindi, it is a small step to learn to read it as well.
Best cut and paste the glyphs on strong (300+ gsm) paper cards yourself, no fancy digital stuff, so you can take your time, as needed for learning anyway.
Switched from HantekDSO to OpenHantek for the Voltcraft model 2090 DSO.
