Solar energy is renewable, free, widely available and clean form of energy. It is considered as a serious source of energy for many years because of the vast amounts of energy that is made freely available, if harnessed by modern technology. Many people are familiar with so-called photovoltaic cells, or solar panels, found on things …
I²C vs SPI Today, at the low end of the communication protocols, we find I²C (for ‘Inter-Integrated Circuit’, protocol) and SPI (for ‘Serial Peripheral Interface’). Both protocols are well-suited for communications between integrated circuits, for slow communication with on-board peripherals. At the roots of these two popular protocols we find two major companies – Philips …
The temperature controlling system maintains a user programmable room temperature where air conditioners are not provided. For this purpose we need a cooler and a heater. Cooler is used for decreasing temperature and heater is used for increasing temperature. This project also shows the real time temperature in degree centigrade. It can be used in …
Welcome to Hackeda! This website was started to make designing custom electronics less painful. The basic idea is simple: Create a design by choosing from the library of circuits. Use your choices to automatically generate a schematic. Download it. The file format is Eagle 6. Correct footprints are embedded in the schematic so you’ll have …

USB has established itself as the new standard for connectivity. That is why USB connectivity has become the “holy grail” of most embedded applications. Well, let me get straight to the point. If you want to start developing projects with USB interface, you want to have the proper development tools. To have the tools that you need, you either …
The ISL9238 and ISL9238A USB-C™ buck-boost battery chargers support bidirectional power delivery in ultrabooks, tablets, power banks and other mobile products. The single-chip ISL9238 and ISL9238A battery chargers replace competitive two-chip solutions to reduce customer bill of materials (BOM) costs by up to 40%. Both ICs employ Intersil’s patented R3™ modulation technology to extend battery …
The Withings Body Cardio is the latest in the brand’s range of smart health-centered devices, and the second Withings product we’ve tackled in this series! It’s a smart scale with a pretty impressive set of metrics. It detects weight; fat, muscle and bone mass; hydration level; heart rate; PWV (Pulse Wave Velocity); and it shows …
How to Read Your First Autodesk EAGLE Schematic Like a Pro in 3 Easy Steps The schematic forms the building block of every electrical circuit, and even if you aren’t designing one yourself, knowing how to read one is invaluable. And with some schematic reading knowledge in hand, you’ll be able to design, build and …
O droid is a great development mini PC board to make different IoT or other tech projects on. Needless to describe all the advantages of this marvelous device, as any reader of this post is likely to be really into this growing community. But if you are new to these boards, there are a bunch …
Description This is a 1×1 inch PCB module with two tiny solar cells, a highly efficient Li-Ion battery charger and with two regulated outputs (3.3V and 1.8V). It harvests enough power from indoor light to power a simple BLE or LoRa sensor. The board has castellated vias so it can be surface mount soldered onto …
