Yes, I know what you are thinking: “oh no, please not another TVBGone…” Anyway, this instructable is for the newbies as me which are still experimenting with Arduino, and prefer to program an Atmega168 in Arduino than an AtTyny85 with other methods. This circuit is based on Mitch Altman’s TVBGone and on Ken Shirriff’s blog where the software […]

Texas Instruments (TI) announced the world’s first multichannel inductance-to-digital converters (LDCs). The four new devices in the LDC1614 family expand the innovative LDC portfolio, a data converter category that TI first introduced in 2013. The devices offer two or four matched channels and up to 28-bit resolution in a single integrated circuit (IC). The combination […]

This project is about to DIY an Arduino board wth an ATMEGA644P or 1284P to have more INPUTS/OUTPUTS than on the atmega328P. You can buy an arduino mega but it’s more expensive. The microcontrollers will be bootloaded with Sanguino and the project seems to be like another one called CALUNIUM. On this clone you will […]

Any hobbyist can charge a battery quickly, but can you do it without an explosion, excessive heating or major degradation in battery cycle life?   Well many companies have managed fast charging techniques  that typically use specialized algorithms. These algorithms take into account the chemistry of the battery and some sort of non-standard charging rate […]

For my Word Clock project, for which I built a custom 8 x 8 LED Matrix with controller, I needed a much smaller footprint DIY-Duino (board for an ATMega328P microprocessor), one that would have all of the main functionality of my previous DIY-Duino boards (such as the Arduino Uno I2C Master board). As I’m not […]

emon-server RESTful service converting ‘flashing lights’ or ‘pulsing magnets’ on electricity and gas meter to JSON using the trustful 555 timer chip, Python, NodeJS and a Raspberry PI Summary A cheap 555 timer chip acting as Schmitt trigger combined with a phototransistor or LDR is taped to the ‘flashing light’ or ‘pulsing magnet’ on the […]

A while ago I found some blog posts explaining how to use a LED matrix as a pendant (http://hackaday.com/2013/01/10/8×8-led-matrix-pendant-sealed-in-a-block-of-epoxy/ and https://sites.google.com/site/tinymatrix/ ). The 8×8 matrix pendant looked cool, but it was missing detailed information on which parts to use and how to solder everything together. With help from a friend, Uriel Guy, we managed to […]

Intersil’s ISL8117 is the first 60V sync buck controller able to bypass the intermediate step-down conversion stage traditionally employed in industrial applications. The controller’s low duty cycle enables the direct step-down conversion from 48V to a 1V POL, making it possible for you to reduce system complexity and solution cost in a variety of applications. […]

Summary The MMA955xL platform as a sensor hub is an intelligent sensing hub with built-in accelerometer, signal conditioning, and data conversion with 32-bit programmable microcontroller and temperature sensor. In addition, it has a second I2C bus and one external analog input, which can be monitored using the on-chip Analog-to-Digital (ADC). This unique blend transforms Freescale’s […]

Ever dreamt of controlling an appliance like a CFL or a fan at your finger tips and thinking for a cheap solution? Well, then you are looking at the right instructable!! This instructable will provide you with a cheap and best possible solution to control your switch operated appliances through an existing IR remote using […]
