A question, a problem or a suggestion, don't hesitate : a little email
Hardware
Step by step, the manufacture of an home made printed circuit board (PCB).
Power supply
A basic power supply for every electronic hobbyist.
Two variable outputs (24V 1A) and a fixed output (5V 2A).
Oscilloscope
An indispensible tool for every analogic designer.
Logic analyser
A very useful tool for digital projects.
An interface between a PC parallel port and the standard bus "Peri1" I use for my microcontroller based projects.
An interface between an USB bus and the standard bus "Peri1" I use for my microcontroller based projects.
A connector allowing an easy connection of a Peri1 bus on a breadboard.
An extension of the parallel port interface to control an I2C bus or to program serial E2PROM (SPI or I2C bus).
An USB to I2C interface using a RAVAR MOD4 module with C interface library.
Step by step, the installation of a RAVAR MOD4 module under WinXP and a test program.
EPROM programmer
An EPROM (and E2PROM or microcontroller) programmer, PC controlled through the parallel port interface.
Lattice ispLSI tools : programming and programmer (including a test with an ispLSI1016).
GAL programmer
A GAL programmer (16V8 to 22V10) found in ELEKTOR magazine.
Very useful to reduce "glue" logic and to allow modifications during tests (re-programmable devices).
Some tests on coils for switching power supplies :
- calculations
- test apparatus
- results of some tests.
Software
C library for I2C components with some test programs.
Usable with the parallel port I2C interface, the USB to I2C interface or with your own interface and interface library.
Schematic and PCB design
To have "clean" schemes and to design printed circuit boards (PCB).
I use EDWIN, 1.51 version.
Gerber2Tiff
A DOS (under Windows) tool to convert Gerber files into Tiff files allowing PCB printing and manufacturing.
