This services follows Frontier’s alternate-airport service from Trenton Mercer Airport which began late last year. It is interesting to note that two of the routes from Wilmington (to Houston and Denver) are longer than any of the routes from Trenton, perhaps enabled by Wilmington’s longer runway. The other three are to locations also served from Trenton.

Today’s Featured Map shows the new service from Wilmington, plus the Trenton service in grey.

Reverse-engineering and simulating Sinclair’s amazing 1974 calculator with half the ROM of the HP-35

I’ve reverse-engineered the Sinclair Scientific calculator. The remarkable thing about this calculator is they took a simple 4-function calculator chip and reprogrammed its 320-instruction ROM to be a full scientific calculator. By looking at the chip, I’ve extracted the original code, reverse-engineered how it works, and written a JavaScript simulator that runs the original code and shows what the calculator is doing internally.

Exploring the TI MSP430 platform with Energia Arduino-compatible IDE

Posted on 26 September 2012. Tags: , , , , , , , , , , , , , ,


Over the last year or so Texas Instruments have been literally pushing their MSP430 development platform hard by offering an inexpensive development kit – their LaunchPad. For around ten dollars (not everyone could get it for $4.30) it includes a development board with flash emulation tool and USB interface, two of their microcontrollers, crystal, USB cable and some headers. It was (is?) a bargain and tens of thousands of LaunchPads were sold. Happy days.

However after the courier arrived and the parcel was opened, getting started with the LaunchPad was an issue for some people. Not everyone has been exposed to complex IDEs or university-level subjects on this topic. And to get started you needed to use a version of Code Composer Studio or IAR Embedded Workbench IDEs, which scared a few people off. So those LaunchPads went in the cupboard and gathered dust.
