Okay firstly the reason I wrote about the clock system instead of I/O ports or something else in this second post of the XMega series is simply because of the fact that without understanding clock configurations you won’t get what you want from your chip. Since XMega’s clock system is software-level configurable and complex at […]

After the success of my first nixie clock made out from a rosewood block, I decided to lose no time and to carry on with the next one. As some of you guys already know, or imagine, lately I’m indeed a little bit addicted to nixie-mania. I’ve bought many nixie tubes on eBay, and I experienced

Breaking in The iFixit team uses a suction cup and “some gentle spudgering” to reveal the innards. (There’s a booby trap, but you’ll have to check that out in the full teardown.) iFixit’s suction cup and spudger (shown) enabled the team to open the iPhone 5s carefully. (Source: iFixit) Once inside, iFixit says: As we

Abstract: I recently stumbled across an interesting fact in the datasheet for the ATMEGA32u4, the microcontroller I am using for my Einstepper Project. I was surprised to find that Atmel had included a temperature sensor in the core of the device that you can read using the internal ADC. As it turns out, there are

Introduction The main incentive behind this project was to see how much I could cram, in terms of both hardware and software, into a wristwatch-like device that is no larger than the display itself. An OLED display was chosen for being only 1.5mm thick and not requiring a backlight (each pixel produces its own light),

FTDI introduces on the market technology EVE – complete graphic solution suitable also for slower microcontrollers. Paraphrase with the woman´s name is very near to a name of a new technology of display control – EVE – embedded video engine. Company FTDI as a well known producer of USB solutions with a slogan USB-made-easy, decided
Is a display design difficult? Leave it to „Eve“! Read More »
Introduction It can be quite tricky to reuse lithium-ion batteries from discarded equipment since these cells are often charged inside the equipment. In other words, there is no separate charger that can be reused. Fortunately, it turns out to be fairly easy to build a charger for used (or new) lithium-ion cells. Like most people,

Lantronix xPico WiFi module enables to directly configure a target device via a software access point – without a need to access a client´s network. Lantronix xPico WiFi is a new module with a dual serial port (+USB 2.0, + SPI) enabling to connect target devices into WiFi network with several features making it user

Researchers at the University of California, Riverside have developed a silicon anode that would allow us to charge lithium-ion batteries up to 16 times faster than is currently possible. The new design relies on a three-dimensional, cone-shaped cluster of carbon nanotubes that could also result in batteries that hold about 60 percent more charge while

This is a simple TRIAC AC load dimmer used to control the power of a resistive load such as incandescent lamp or heater element. The max load it can handle is 400VA. Such a circuit is often found on cheap commercial light dimmers and is prooven to work reliable for the rated power. The circuit
