Often seen people making online digital oscilloscope, DSO must have digital-analog conversion unit, according to d/a conversion circuit can be divided into two modes: 1. Special ADC chip + single-chip, 2.
We've been keeping up with the ongoing software developed for the ESP32 WiFi chip, and that means a lot of flashing, hooking up random wires, and rebooting. Along the way, we stumbled on an Easte
NextThingCo, makers of the very popular C.H.I.P. single board Linux computer, have released the latest iteration of their hardware. It's the C.H.I.P. Pro, an SBC designed to be the embedded brains o
Retrocomputing is an enjoyable and educational pursuit and — of course — there are a variety of emulators that can let you use and program a slew of old computers. However, there’s something attractive about avoiding booting a modern operating system and then emulating an older system on top of it. Part of it is just aesthetics, and of course the real retrocomputing happens on retro hardware.

For some projectes with rapsberry and the smaller arduinos I need to switch some relays. Because of the GPIO outputlevel (3,3V) its hard to find some relays that are able to switch larger loads and can operated directly with the given 3,3 volts.
So i decided to build my own relay-board. The 5Channel one i build here is around 10€ for the pieces. In addition you only need a soldering iron, solder and some tools to cut the wires and bend the legs of the components.
The Pi-Pan is a pan-and-tilt device for the Raspberry Pi camera. mindsensors.com distributes the kit and their website has instructions for an earlier version of the device.
In the front yard of Rory Aronson’s San Luis Obispo home (that he shares with 9 roommates), a robot is tending his garden- seeding, watering, weeding an
You need a certain type of monitor to use Raspberry Pi. Most of people do not have a monitor specifically for his/her Raspberry Pi. By taking this method, you can make your tablet or smartphone a screen for your Raspberry Pi.
The Raspberry Pi Zero is small enough that it could almost be mistaken for a USB gadget, rather than a standalone computer. Maybe that was the inspiration that drove [Novaspirit] to completel

This is a follow on to my last post which was about building a prototyped lithium charging ESP8266 (ESP12) breakout board along with some power management firmware features. Having had reasonable success with the stripboard prototype, the next step was to create a PCB version of this project.

Sending data over an RF link to a PC There are many articles on the internet describing how someone can add wireless capabilities to a project. A plethora range of options and technologies exist and the choice is based upon the specific application.
Hi friends, in this instructable I would like to introduce you to a good instructable which is needed in any home, i.e. a thermo-hygro meter which not only give you average temperature and relative humidity of any indoor space but the variation of these two parameters in any time duration which depicts the variation to see how these parameters change and enable us to draw conclusions for ourselves about the degree of the comfort of our environment.
This guide is to build a very basic FTDI to ESP8266 breakout board adapter. It's a great way to send your program on the fly without the need for a breadboard and jumper wires.
This instructable shows how to create a time switching battery powered solar charged circuit, which is used to power an Arduino Uno and some peripherals (sensors, communication modules, etc.).If you want to design a remote data logger, power supply...
