1) The quiz contains 12 questions about electronics, FPGAs, hardware, and IoT with prizes for participation including hardware, bits, and books. 2) The questions cover topics like resistor color codes, FPGA development boards, transistor packages, DSP slices, inductance units, filter types, recent FPGA families, capacitor equations, tradeoffs between CPU/GPU/FPGA/ASIC, IoT device projections, new IoT interfaces, and the price of an Unashield device. 3) Participants are encouraged to answer using pen and paper for fun, with results to be shared at a future Hackware version.

1. Hackware v2.7: IoT Special
Hackware Quiz
The important thing in Hackware is not triumph, but the struggle; the essential thing is not
to have conquered but to have learned well. To spread these principles is to build up a
strong and more valiant and, above all, more creative and generous community !

Question 8
When capacitors are arranged
in parallel, the equivalent
capacitance is i.e. Ceq = C1 +
C2 + C3 + ....
When capacitors are arranged
in series, the equivalent
capacitance is
