This machine consists of 2 servos controlling an aluminum arm with a pen attached. It is an attempted improvement on DM#1 by moving the weight back to the shoulder The belt used on this machine was completely unusable because it slipped and then all coordinates were useless. This caused the machine to leave the boundries… Read more »

This is a timer I built using a gutted alarm clock and a 2051. I developed the hardware using a DS5000 based emulater and the 89s8252 based programmer that I built last fall. Schematic The emulator The programmer Testing with actual chip The carcas The finished product buried on the messy bench code /*———————————————————————timer.c** This… Read more »
Bootstrap 89×051 programmer This is a result of many searches through the web to put together a 4051 programmer. Most of the programmers required a preprogrammed 4051. • Many of them used the reference circuit provided by atmel to supply the 0/5/12 programming voltage. This circuit used a 317 and a series of odd resister… Read more »
The 8051 has come along way since I was a student. Windowed eproms etc, I would go into it but eventually I would sound like one of those old IMSI 8080 owners talking about loading their bootstraps one bit at a time. I have been working with the ds5000 and the atmel flash based family…. Read more »
