Withings GO activity tracker teardown

For this first edition of the hardware teardown, we’re dissecting technology and lifestyle brand Withings’ cheapest activity and sleep tracker: the Withings GO.   Since they launched their first connected weighing scale back in 2010 (the WiFi Body Scale), I’ve been a big fan of Withings. They make beautiful products that integrate seamlessly with their online platform and that seem to have a very decent li ...

Public Release of ESP32 SoC The Big Brother Of ESP8266

It has been about one year since the announcement of ESP32 SoC and the beginning of its beta testing for some developers. Last Month we covered the release of ESP-WROOM-32 module datasheet,  which promised that “New SDK features, tutorials and example applications will be released over the next few months.”. The ESP-32 datasheet was released at the end of August. So let us discover the details of ESP-32 SoC ...

ICS501 simple frequency multiplier

Today I made a high frequency multiplier using a single component: the ICS501 PLL clock multiplier IC. This chip provides 2x, 5x, 8x (and more) clock multiplication using an internal phased-lock loop (PLL). At less than a dollar on eBay, $1.55 on mouser, and $0.67 on Digikey, they don’t break the bank and I’m glad I have a few in my junk box! I have a 10MHz frequency standard which I want to use to measure ...

12V NE555 PWM Controller

While making my mini table saw I bought a 12 V motor speed controller module from eBay. Fair enough, I thought ... that was an easier and straight forward solution. But then I decided to make my own. I did some hunting around on the interweb and found a pretty good starting point in Circuits Today, but then, I needed to make some modification and tweaking of the circuit. I wanted to add in a toggle switch, ...

Open source 25-core processor can be stringed into a 200,000-core computer

Researchers want to give a 25-core open-source processor called Piton some serious bite. The developers of the chip at Princeton University have in mind a 200,000-core computer crammed with 8,000 64-bit Piton chips. It won’t happen anytime soon, but that’s one possible usage scenario for Piton. The chip is designed to be flexible and quickly scalable, and will have to ensure the giant collection of cores ar ...

Filtering Noisy Arduino Measurements

Measurements from the real world often contain noise. Loosely speaking, noise is just the part of the signal you didn’t want. Maybe it comes from electrical noise: the random variations you see when calling analogRead on a sensor that should be stable. Noise also arises from real effects on the sensor. Vibration from the engine adds noise if you’re measuring the acceleration of a go-kart, for example. Filte ...

DIY USB to TTL Converter

Now that the PC’s com port or Serial port is almost obsolete there is quite a lot of requirement for USB to TTL or USB to RS232 converter. USB to TTL converters are required for interfacing microcontrollers to PC it is also required for loading code in Arduino Mini, setting/modifying ESP8266 firmware. Over here we are going to make a do it yourself (DIY) USB to TTL Module on a breadboard. Lots of USB to TTL ...

Drone The Quadcopter

"Drone The Quadcopter" is an featured UAV. I design my project with F450 arm in X-mode design. The full operation takes place via a Flysky FSCT6 remote control unit which gives a better operating range of 800 Meter to 1.2KM. If you are a beginner in this field then you are on the right place. The ultimate goal of our project is to learn aerial vehicles which can be flyover a long height and over a long rang ...
