I'm surrounded by lots of electronics today, unfortunately I'm hooked up to most of them. Plus various tubes.

I'm sure normal service will be resumed soon.

18650 Li-Ion battery powered Wemos D1 with Wemos Battery Shield - DONE 30 days achieved

Wemos has developed a series of shields for the Wemos D1 : DHT Shield Battery Shield Matrix LED Shield Buzzer Shield Dual Base SHT30 Shield WS2812B RGB Shield ProtoBoard Shield 1-Button Shield Micro SD Card Shield Relay Shield DC Power Shield Tripler Base Motor Shield OLED Shield The good thing is that you can stack them on top of another. Let's take a look for now to the Battery Shield that is now on version 1.2.0 and it has a retired version 1.1.0 Get the schematics from here version 1.1.0 and 1.2.0 to see the differences. An immediate visual difference is the inductor on the V1.1.0 is much higher than the one on V1.2.0 but is not all. Battery Shield V1.1.0 Since I didn't found yet the version 1.2.0, I used the V1.1.0 from here . and the Wemos D1 mini from here . I've also added an BMP180 pressure and temperature sensor . Characteristics: Charging Voltage: max: 10V, recommend: 5V Charging Current: max: 1A Lithium Battery voltage: 3.3-4.2V Boost Power Supply: 5V(max: 1A...

Using Big Data and the Internet of Things to Help End Poverty

Most of us have been bombarded by fantastical visions of the future – where we no longer need roads, machines take care of our every need, and a doctor can replace a human heart with one created by a 3-D printer. That time is coming. With smart phones increasingly commonplace in even the poorest countries, we’re on the brink of a new age, where technology will help solve some of the world’s biggest challenges. But will poverty be one of them? At the World Bank Group, we think the answer to that question should be yes. We’re committed to doing all we can to help developing countries harness innovation and build the human capital they will need to compete in the technology-dominated economy of the future. To that end, we’re engaging and learning from innovators and disruptive technology firms; collaborating on research; and exploring new partnerships to leverage data, knowledge, and new technology to help achieve our goal of ending extreme poverty by 2030.

Arduino CNC shield control Stepper motor with DRV8825

CNC shield is quite useful for stepper motor driving. Here, I demonstrated how to use simple arduino code to drive stepper motor with DRV8825. First, just simply mount CNC shield onto Arduino Uno. Make sure the direction of the shield was right, where both the USB port and power supply wire was on your left hand site. The blue wire is my power supply which can be connect to 12-36V of power source. Next step you can mount the DRV8825 chip onto the CNC shield. Make sure the DRV8825 chip goes like this direction. If you put the chip in the wrong direction, you will probably damage it. By adjusting the jumber underneath the DRV8825 chip, motors can be driven with different kind of microstepping mode. I put three number here so it means that I set it into 1/32 step driving mode. Which is the most precise one of DRV8825. The motor can connect to the right site of the DRV8825. Plug in the usb to your computer and upload these coded which will generate steps moving in both direction sequ...
