With the smartcard PC emulator you can interface to any device that accepts smartcards (ISO 7816), like cell phones (with the SIM adapter (not made in this project)) or for instance digital cable tv receivers, chipknip devices etc. It can be used for investigative purposes, reverse engineering and other things.
I have used the design from circuitsarchive and have converted the PCB layout (through hole) below...
by removing the information surrounding the board, leaving the actual PCB layout and convert it to 500 dpi. This archive contains the same image in 1200 dpi and i've edited it and converted it to 500 dpi PNG so that it can be used on the Modela for milling, but ran into a lot of problems, the dimensions of the design do not translate well with the cad.py program and the modela toolpath. Mainly the design is not made for milling on the modela, and the 1/64" milling bits kept breaking, so i've decided to redesign the whole project in Eagle. (which as of currently i am still working on)
The tutorial provided by Mark Boon provided a great starting point. The tutorial provides a link to design rules for eagle that are important, because they instruct the Eagle PCB design program to create PCB milling and drilling files that are compatible with the modela and can mill drill completely and quickly. There is also a Eagle ULP (user language program) for modela milling and drilling that creates the toolpath. After i have succesfully created this project using this workflow i will provide a step-by-step tutorial on how to create any (simple) circuit on the modela for through-hole electronic design.
This project uses through hole electronics, (which means that we drill holes through the PCB boards and the electronic components are soldered on the bottom of the board - more info [here ADD].
The modela can be tricky to use, so i will first explain how to set that up using the linux PC with the USB-RS232 converter. USB-RS232 converters can have timing problems [?] and other compatibility issues, but for PCB milling on the modela the one in the fablab works in this setup [check].
The rml file is ready made here. [make]
Instead of the MAX232 i'm using the compatible MAX3232 that is more easily available nowadays.
- milling
- drilling
- soldering
Parts list :
i've ordered the parts through www.dickbest.nl, the PCB which is FR1 (paper based) with copper on both sides should be in stock at the fablab, as well as some of the other parts.
What you need to get is the 74LS 07 and the MAX3232CPE+.
