In retrocomputing circles, it’s often the case that the weirder and rarer the machine, the more likely it is to attract attention. And machines don’t get much weirder than the DEC Rainbow 100-B, sporting as it does both Z80 and 8088 microprocessors and usable as either a VT100 terminal or as a PC with either […]

Story Throughout my years of experience, I’ve created numerous timers and encountered a plethora of mobile apps. However, when I found myself in need of a straightforward solution to seamlessly automate the on-off cycle of a circuit I was actively developing, none of the available options proved to be the right fit. Consequently, I took

IDT ZMOD4410 Metal Oxide Gas Sensors are designed to detect Total Volatile Organic Compounds (TVOC) and monitor Indoor Air Quality (IAQ). The ZMOD4410 gas sensors consist of a signal conditioner that measures the Metal Oxide (MOx) conductivity, a function of gas concentration, and controls the sensor temperature. The sense element of the gas sensor consists

Introduction Sometimes, it is necessary to add a temperature indicator into your projects. Therefore, in this tutorial you will learn how to hack your analog Voltmeter and convert into an analog Thermometer using Arduino and a DS18B20 temperature sensor. DS18B20 Module In the first place, the Maxim DS18B20 digital thermometer provides 9-bit to 12-bit Celsius
Arduino Analog Thermometer With DS18b20 Module Continue Reading
The 74181 ALU (arithmetic/logic unit) chip powered many of the minicomputers of the 1970s: it provided fast 4-bit arithmetic and logic functions, and could be combined to handle larger words, making it a key part of many CPUs. But if you look at the chip more closely, there are a few mysteries. It implements addition,
Inside the vintage 74181 ALU chip Continue Reading
A computer’s arithmetic-logic unit (ALU) is the heart of the processor, performing arithmetic and logic operations on data. If you’ve studied digital logic, you’ve probably learned how to combine simple binary adder circuits to build an ALU. However, the 8008’s ALU uses clever logic circuits that can perform multiple operations efficiently. And unlike most 1970’s
