FlashMyPin vs RPN

Modern power meters require the entry of a PIN using a flashlight. To input the different digits in the form of blinking signals, one must enter them in a kind of Morse code. One blink corresponds to one, two blinks to two, and so on. This can be very tedious and time-consuming, and mistakes can easily happen due to the need for precise timing. FlashMyPin is the solution: Instead of manually inputting individual blinking signals using a flashlight, you only need to type in your PIN and the flash on your phone’s camera blinks in the correct pattern. You simply need to hold your phone in front of the light sensor of your smart meter, and your PIN will be entered in no time. FAST No ads. No registration. FlashMyPin is ready to use right away. SIMPLE With its intuitive interface, FlashMyPin is easy to use. EFFICIENT Instead of laboriously entering individual commands through blinking lights with a flashlight, FlashMyPin saves you a lot of time! CONVENIENT The most common commands are already stored in the app, so you can get started right away.

RPN-55 SD is the first photo-realistic simulation for the iPhone of Hewlett-Packard's low-cost alternative to the famous HP-65 programmable scientific calculator. Produced from 1975 through 1977, it was the "Merlin" member of the classic HP calculator series, priced at $395. HP claimed that it featured "(...) more pre-programmed functions than any other scientific pocket calculator in the world." A main feature of the HP-55 was a crystal-controlled 100-hr digital timer with the ability to store times while the timer was running and later recall them. On RPN-55 SD the timer may also act as a 12-hr or 24-hr clock, including date and weekday display. While the simulator works just like the original calculator – except being much faster and having twice the program memory – you can turn on extended features to make it even more enjoyable to use. RPN-55 SD comes complete with original HP programs built in. Features: • Photo-realistic look-and-feel • Vintage mode or Extended mode • Programmable (99 steps), conditional branching • Insert and delete steps with automatic address correction • Delete range of steps • Subroutines (4 levels) • 20 registers, "continuous", with unrestricted store/recall arithmetic • "Live" register view • Program listing view • Program library view • Store and retrieve any number of programs • 100-hr timer supporting 10 split times and 12/24-hr clock mode with date • Swap unit conversions with additional functions, e.g. hyperbolics • Sharing: e-mail, AirDrop, Dropbox, copy, paste, print • 112 programs pre-installed Calculator functions: • Statistics (linear regression, mean, standard deviation, correlation coefficient, x- and y-estimates) • Trigonometric functions (degrees, radians, grads) • Polar/rectangular conversions • Inverse, square root, logarithm, exponential, pi • Storage arithmetic (store and recall) • Percent, absolute, integer, fractional value, round • Factorial • Random number • Unit and hours conversions Details: cuveesoft.ch/rpn55
