Arduino Project – The distance calculator I have been playing with Arduino (micro-controller) for about 2 years now and I am becoming more and more passionate about circuits. For those who are not aware of Arduino, check out my article “Arduino – A Guide for Beginners“. Recently, I was testing some new components that I […]
If you are interested in building your very own RPN calculator you might be interested in a new project published to the Instructables website this week by member Shiura. Using a CNC machine, the calculator has been constructed using a wooden case together with acrylic screen protector, and a little Arduino hardware. Featuring an Arduino Nano microcontroller board and
This is a 4 band Mechanical Color Code Resistor Calculator, The idea of making this Mechanical Resistor came when I accidentally dropped my box of resistors and all resistors (1300 of them) got mixed up. ooops! . Thank god there’s an APP for that, So while picking them up (the resistors) and soaring them out

By: Sonya Singh Computer Engineering Step 1: Project Overview Have you ever dreamed of building a 2-bit adder calculator, which can display the results in both binary and decimal? Well, look no further – Through this guide, your dreams have finally come true! Not only will you learn to build the adder, but you’ll also
[Jure Spiler] was at a flea market and got himself a spectrophotometer — a device that measures absorbance and transmittance of light at different wavelengths. This particular model seems to be about 25 years old, and it’s controlled by a built-in keyboard and uses a graphical LCD to display collected data. That might have been acceptable when

Hey, welcome to my first instructable where I will be helping you create a calculator. It’s basically made up of a 16×2 LCD, with an Arduino UNO that you can use in order to make quick calculations from far distances. I know, it doesn’t make sense right, well I did not have a keypad but
This command-line Python script is a utility to help calculate parameters for timing belt drive systems. A more general discussion of designing with timing belts can be found on the Timing Belt Guide pages. Installation Requirements The code requires a working installation of Python 3 with scipy. For suggestions on setting up your system please see Python 3 Installation.
Friction can often seem like a ‘boring’ force. Something we are all familiar with from a young age, but friction does a lot more than just make objects slow down – although that is a big part of this project. Friction allows the world to work as it is today. Friction between your shoes and
This weekend marked the 49th anniversary of the legendary Intel 4004 microprocessor, and to celebrate [Erturk Kocalar] combined the old and new in this intriguing Retroshield 4004 / Busicom 141-PF calculator project. We have reported on his Arduino shield project before, which lets you connect a variety of old microprocessors to an Arduino so you can experiment with these
There was a time when any electronics student would have a slide rule hanging off their belt. By the 1970s, the slide rule changed over to an electronic calculator which was a pricy item. Today you can buy calculators at the dollar store. [JohnAudioTech] pulled out an old Radio Shack vacuum fluorescent display (VFD) calculator and found
