It isn’t hard to imagine a scenario where you are stuck at home all day with nothing to do and certain items are in short supply. Sure, bathroom tissue gets all the press, but try buying some flour or a freezer and see how far you get. Plus online shopping has given up on next […]

WCH (Nanjing QinHeng Corp.) has recently launched a CH55x family of microcontrollers based on an 8-bit C51 core with a USB interface, and I/Os. The boards all come with different I/Os configuration depending on the selected part number. Electro dragon, the popular online store that offers a range of electronic components is now listing one of the
CH551 is a $1.80 USB Mini Development board based on the 8-bit C51 micro-controller Continue Reading
Experts on cognition tell us that most people think they know more than they really do. One particular indicator for that is if someone is an expert in one field and they feel like all other fields relate to theirs (everything boils down to math or chemistry or physics, for example). This causes them to
Tektronix, a US-based company, has introduced two new Keithley 6½-digit models to its line of Digital Multimeters (DMMs) and data-acquisition systems: The new DMM6500 DMM and also the new DAQ6510 data-acquisition system. The company has also upgraded their Kickstart measurement software to version 2.0. Keithley has long been a dominant provider in the 6½-digit DMM market. With the DMM6500 and DAQ6510, the company looks forward

It’s great to see people are out there trying to find fun ways to exercise amid the current crisis. Although jumping up and down isn’t great for the knees, it does give decent cardio. But if you don’t have a rope or a puddle, we admit that jumping can lose its bounce pretty fast. Quarantine

Every day of our lives we get bombarded with different sounds around. Loud music, radio, people talking on their phone, automobile, traffic, and those unknown late night quacking sounds. All of these sounds are what makes our day to day activities, and we have even gotten accustomed to most of them and rarely get disturbed by them.

With all the hands-free dispenser designs cropping up out there, the maker world could potentially be headed for an Arduino shortage. We say that in jest, but it’s far too easy to use an Arduino to prototype a design and then just leave it there doing all the work, even if you know going in

In times like these, we all need to look beyond ourselves. This project might help: OnStep is an open-source telescope controller, a device that controls a telescope to point at something interesting in the sky. Want to take a look at M31? Use an app on a PC or smartphone, select the object and the

Ever miss the simple days of using a PC’s LPT1 parallel port to bit-bang GPIO over 8 output pins and 4 input pins of the DB-25 connector? I sure do. My first design project as a BSEE graduate in 1993 was to design a LPT1 controlled test fixture for the Motorola MDT-9100-T data terminal (shown
Hardkernel has produced a single-unit version of its four-unit, 32-core Odroid-MC1 cluster computer for running Docker Swarm, Build Farm, and other parallel computing applications. The design offers greater flexibility for users to combine Odroid-MC1 Solo units for a “single unit, 2, 3, 4, 5, 6, or n stackable cluster”. The octa-core Odroid-MC1 Solo costs $48. Combing one or more Solo
