The purpose of this design is to offer solution compatible with official SmoothieBoard for DIY SMT Pick&Place Machine.
The purpose of this design is to offer alternative to official PIC18F/PIC16F Quick Programmer (P1618QP) bootloader programmer, available as part of AN851 project on Microchip web pages.
As the price of ICL7107 decreased dramatically through the time, I decided to use my stocks to build a modules for various purposes.
Therefore I designed the PCB, which is divided into two parts, but could be manufactured as one. The 2 parts are connected with right angle 25 pin header, which allows to use LED display vertically, while the driver is horizontally oriented.
Or you can use wires for connection between boards.
You can see ICL7107 Voltmeter Module PCB on the following pictures:
I was looking for such scripts for long time, but with various results. Finally, I build following working scripts, which I am using for transfer files from PC to web server and back and for backup of various folders.
Script for setting permissions for web server without influencing *.sh files (scripts itself):
#! /bin/sh
sudo chmod 660 -R $(ls --ignore='*.sh')
sudo chown www-data:www-data -R $(ls --ignore='*.sh')
It is a long time ago, when I got Willem EPROM programmer. As the time is going quickly, someone could see this programmer is obsolete already. But there is simple, but big advantage of this device - low level modification possibility!
One of the requirement at the moment is decreasing supply voltage of modern chips. Therefore it is important to have ability of modern programmer to fulfill datasheet specification.
The target of these designs is to provide the possibility of programming various chips by Willem EPROM Programmer and optionally test it's hardware functionality.
