8-bit bus control widely used 12-bit DA converter Universal
The 8 microcomputer data operates with an 8-bit parallel output, while also accommodating serial input for D-A converters. Typically, data must be entered in two groups and processed as a whole. The requirements for data latching involve 16 straight odd...
OSU8 Microprocessor Project (1994)
OSU8 began as a student project in 1994 to create a simple but functional 8-bit microprocessor, starting with a definition of the architecture to implementation in a Xilinx FPGA chip, and full-custom CMOS implementation. Over a period of about six...
The EC10 communications receiver
It is important to recognize that the EC10 is a vintage receiver with collector appeal. Any modifications should aim to preserve its original state, and most of the following suggestions adhere to this principle. While replacing all Germanium transistors with...
Suunto PC Interface
This page contains GIF images of the circuit diagram for the Solution interface, the PCB artwork, the board layout, a typical side elevation of the assembly, a parts list, some hints, and a brief overview of troubleshooting. This is a...
Dodd Station
Dodd's 1909 receiver has survived and was discovered among various parts purchased at a yard sale. The components were identified from a photograph of the 1909 Station. Many of these parts were utilized in the construction of Dodd's 1912 station,...
1945 RCA CRV-59AAE Iconoscope Camera
The CRV-59AAE measures 20 inches in length, 9 inches in width, and 10 inches in height, with a weight of 33 pounds. This device is over 60 years old and is in excellent condition, showcasing advanced miniaturized technology for its...
16-bit homebuilt computer project
A functional interrupt-driven RS/232 driver is currently in operation, supporting hardware flow control at a baud rate of 9600 bps. Although higher baud rates are achievable, stability has yet to be verified. Helper routines have been developed to facilitate the...

16-bit adjustable reference uses 8-bit digital potentiometers
It may be easy to find a precision voltage reference for your application; however, a programmable precision reference is another matter. The circuit in Figure 1 yields a precision reference with an LSB of 62.5 µV. The circuit is a...
