ADS1256 - RP2040 Custom DAQ with GPIOs
Curious Scientist Apr 03,2024
This is my (hopefully) last iteration of the ADS1256-based DAQ board. I replaced the ATmega32U4 microcontroller with an RP2040 and made the whole board much more compact so I could fit it in a very specific metal enclosure. The RP2040 is a faster microcontroller, so it will be more reliable to deliver the data quickly or even do some processing onboard. It also has a large flash memory which allows larger code, for example, a more complex signal processing. I picked a fairly large flash (W25Q128...

How to make simple portable PEMF Magnetic Pulser
Pavleski Mar 28,2024
 PEMF (Pulsed Electromagnetic Field Therapy), which is also known as magnetic pulse therapy uses electromagnetic fields that are applied to the body in pulsing patterns to promote healing and overall wellness in the body. These fields are typically low-frequency and mimic the natural electromagnetic fields produced by the body. PEMF therapy is used in various medical and wellness applications. It is commonly employed for pain management, wound healing, and bone-related disorders. In ad...

Smallest ESC with Arduino
ELECTRONOOBS Mar 24,2024
This is my design of probably the smallest ESC for triple phase brushless motors you can find out there. It is only 8mm wide and 2 cm long. But is it perfect? Yeah, it is, obviously. Nah guys, just kidding. It still has some small errors but it works almost as I expected. As you all know I’ve made a lot of ESCs on this channel, and my last version works as any other commercial ESCs reaching very high speeds. But I wanted to make a smaller version, the smallest I could possibl...

NodeMCU Based: 3D Printed Indoor Gauge Thermometer
Adhikari Mar 23,2024
Had some time this weekend and a desire to create something new and interesting, so went ahead and created an Arduino/NodeMCU based indoor dial thermometer. This device displays the temperature in degree centigrade on a D-Shaped Gauge as well as on a 7-Segment display.In addition to that, it also saves the temperature and humidity readings in a MySQL DataBase hosted on a home based Raspberry Pi Server. The data is then displayed using the "Our Smart Home" app.AwardsThis project got featured on&n...
