Iowa State University, USA, scientists have developed a self-destructing battery that can power a simple electronic device such as a four-function calculator for up to 15 minutes and then dissolve in water. This could pave the way for so-called transient...
The present age is the age of speed and speed is life. The automatic section of engineering is playing a big role in speeding up life. Whose unique discovery is Raspberry pi. Raspberry pi is a series of small computers that have been developed in United...
Tearing into Sony WH-CH510 headphones These headphones were stolen off a friend who had owned them for many years as he was going to throw them out. Why were they bin worthy? A piece of plastic snapped on one headphone, which I was able to fix with a...
lsm6ds3, l3gd20, mpu6050, and bmi160 were attached to a small robot. the gyros were read at 1msec intervals. the robot started turning at time=655at the end of the turn, the total angle measured:lsm6ds3: 179.44l3gd20: 173.10mpu6050: 179.66bmi160: 178.53...
The other week I got a few samples of some MAX187 ADC chips, as I was in part curious what was so special about them that warranted the high price tag. Looking into ADC chips all started when I wanted to find a solution to the ESP8266's fairly poor internal...
One of the cool things about using openocd is that you can interact with it, say to figure stuff out for the first time. Then you can program it to be consistent. For example, reading the option bytes worked out like this. 1) Make this openocd.cfg:...
In my previous column, we discussed how everything physical in the universe is made from atoms, which are themselves composed from electrons, protons, and neutrons. Each electron has a single negative (-ve) charge; each proton has a single positive (+ve)...
With some quite decent tooling and equipment coming from China these days, my curiosity was sparked as I saw a rather affordable kinematic mount. For those not familiar with such lab equipment, this is a holder for lenses, prisms, filters or anything...
To make it easier for more non-electronic engineers/ programmers to step into the open hardware world, Makerfabs made this ready-to-use ESP32 display kit. It is based on ESP32S3 4 inch display and a few Mabee modules, with the pre-programmed software,...
During the earlier stages of my PhD I realised I would need H-bridges formy cascaded inverter at a later point. I went about designing andconstructing a very early version of the H-bridge to test. This was the firsttime I had used Altium.
nowadays 3d printers more than just 3d printer. especcialy elegoo neptune series contain high performance linux computer inside. good but elegoo dont give us original image file for restore our printer. a lot of maker loves play with...
Are you getting married but can’t decide which Cricut wedding card will be best? I was hoping you wouldn’t stress as I will help you by teaching you how to make them out of the Cricut machine. Weddings are all about reuniting with close ones,...
Sometimes, a case exists for using multiple computers from a single desk. Several servers could be quietly grinding numbers in the background until they need to be accessed by the user for configuration or maintenance. Sure, buying several sets of keyboards...
Arduino Motor Shield PCB V1 | 4 Motors at Once Hey guys, welcome back. In my previous post, I explained what an H Bridge Circuit is, L293D motor driver IC and piggybacking L293D Motor driver IC for driving high current motor drivers. In this...
