writing small microcontroller applications with the 8051-series of Intel.
I mainly use the Atmel 89C2051, a 8051 derivate in a 20-pin housing. I
ve build an in-circuit-emulator for this chip. The ICE is based on a normal
8031 with ROM, RAM and a serial port. The ICE is connected with a 20-pin
connector with (almost) the same pin assignment. The ICE has two restrictions,
it has not got the internal comparator, that is build into the 89C2051
and it doesn`t have pin P3.7.
I use my good old Amiga for programming the 8031, using GOLDED, TERM,
REXX and some little shell-programs, that form an integrated programming
environment. One push on F1 will save, assemble and download the program
into the emulator. TERM, a terminal program that interfaces with the emulator,
will pop up (or even get started) automaticly. This way i can test the
program very quick.
The ICE serves me very well, If someone wants to know more of this,
email me.
Satellite.
I own a satellite dish for some years now. Nothing fancy, but it does
a good job. My system exists of following components:
A Pace MSS300 reciever, a Philips D2MAC decoder, a self-made
positioner, a 90cm dish an old-fashioned single-band LNB and a self-made
mount, fitted with a Jaeger actuator. Of course the D2Mac decoder is equipped
with a MultiMac II card, so a can choose from a broad variety of channels.
As a result of being an electronics and a satellite enthousiast, I decided
to design a positioner. Take a look at the result of this project. Positioner
