Do people enjoy wasting 300$ on a bulky convoluted system, that only works for special “Teacher Edition” calculators, and is several years out of date; E.G. the TI-Presenter? [Benryves] certainly does not. So instead of purchasing a TI-Presenter, he made his own TV out system for the TI brand of calculators by using an ATmega168, a few passive components, and some clever code. The only draw backs being: you save 280$, it fits in your pocket, and it works for almost any TI calculator. Bias aside, the system does actually have a few caveats compared to the commercial edition, but the pros far outweigh the cons.
Versione commerciale: 300$
Versione DIY: 20$
Per tutto il resto c’è Mastiqatsi. :-)
