Copper vs RPN

Open any EAGLE CAD file (from version 6 and above) directly on your iPhone and investigate the PCB layout and schematics with your finger. Select parts and signals, manage parts and Bill of Materials. Copper creates 3D versions of your PCB including parts that you assign from our extensive 3D model library to your footprints. Copper then renders a photorealistic representation in real time that you can touch, rotate and move in a virtual studio. Setup lights and materials like the solder mask or the floor. Import EAGLE files from any source like the web (just download a ZIP file with EAGLE files), from Github, your Dropbox, or send PCB files directly via Airdrop, Mail or iMessage to your iPhone or iPad. Every file you import is kept in Coppers library. This way you can build up a nice library of PCBs and Schematics right in your pocket. Copper is also available for the Mac and both share the same codebase and file format.

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
