Introducing PCBWeb Designer, our new desktop schematic capture and layout tool that’s free and easy to use. Create multi-sheet schematics, use the parts toolbar that includes the Digi-Key parts catalog, in a browsable and searchable database. The PCB view is always in sync with your schematic, and includes all the tools you need to create a design with up to 12 layers. Then you can keep your gerber files locally or send them off to one of our manufacturing partners for production from within the tool. Download at www.pcbweb.com

This project was made in the memory of my old computer that I played around with as a young boy. I have a lot to thank this machine for, among other things it made me understand what I wanted to do with my life. So in this project I created software and hardware to make it possible to play those wonderful games yet again.
Hardware is really fun! I enjoy doing PCB designs for projects like these. This is why I decided to create a board for this project to see if I could produce something that would suffice to run the emulation good enough. The SID chip was the crown jewel for this board, no doubt about it
The pich for the HW chip was sometimes below 0.5 which made soldering a bitch to be honest. But with some patience, sweat and alot of flux it was indeed possible.

TinyScreen is a tiny customizable display. Play games, get notifications from your phone and display useful information.
TinyScreen is the new way to visualize your environment. With a beautiful color OLED display, TinyScreen is designed to be used to display information from the TinyDuino platform, which stack together like little electronic Lego’s.
With TinyScreen there are several default apps that will work right out of the box – like a Smart Watch app, a Video player app and a video game app. You can use these default apps with NO PROGRAMMING AT ALL!

The Raspberry Pi is much more powerful than an Arduino but it has a few limitations of its own. Its I/O is much more limited, it can’t use common Arduino shields, and it needs a regulated 5V power supply via its USB connection. All those limitations are solved with the PiLeven.

We analog designers take great pains to make our amplifiers stable when we design them, but there are many situations that cause them to oscillate in the real world. Various types of loads can make them sing. Improperly designed feedback networks can cause instability. Insufficient supply bypassing can offend. Finally, inputs and outputs can oscillate by themselves as one-port systems. This article will address common causes of oscillation and their remedies.

Do you like tools usable for several jobs? Gas soldering tool Dremel VersaTip 2000 in a “Decorating kit” edition certainly belongs to such record breakers in the versatility of usage.
Multifunctional gas tool Dremel VersaTip 2000 usable for technical but also creative works was introduced to you in our articles. Soldering, melting, hot-cutting, welding and wood burning (pyrography), bending of metals, application of heat shrinkable insulations, releasing of junctions locked by an anaerobic sealant (bearings and screws) and now also various creative works can be done with a special edition „Decorating Kit (DremelVersaTip2000-6)”. This set also contains a few additions to develop creativity of a user (of families :-)), namely: embossing pen, 3 embossing powders, embossing stones and 2 wooden sheets with pre-cut shapes to try this technique.
Embossing pen contains a slow-drying glue. If we put some embossing powder on to an ornament painted by this pen, it will get sticked in a thin layer. Then it´s only necessary to heat it up by a hot air from the VersaTip tool and an attractive color layer is done. Possibilities of usage of this technique are wide – after some exercise it´s possible to use it for example to mark your own „hand made“ products giving them a mark of unique. In general, the embossing lacquer (glue) can be applied also by a suitable rubber stamp (sold in specialized shops), what can give us a relatively very quality, sharp result.

Freescale Semiconductor today introduced the FXTH87 tire pressure monitoring system (TPMS) family, which is the smallest integrated package TPMS solution available at an extremely light weight of 0.3 grams. The FXTH87 family is 50 percent smaller than competing products, helping designers reduce overall bill of materials costs. Freescale’s newest TPMS system-in-package solution provides low power consumption combined with the highest level of functional integration in one package, featuring a dual-axis accelerometer architecture, pressure and temperature sensor, integrated MCU, RF transmitter and low frequency receiver.

I built a custom OBD II gauge in the clock of my Subaru BRZ (GT86, FRS) and a lot of people wanted me to build them one. Here is how you can build one of your own. My wife is about to give birth to our second son and all the code is open source, so I have nothing to lose by posting this.

Environmental energy harvesting is a possible source of power for Internet of Things (IoT) sensor nodes but needs careful management. Unless harvesters based on solar or thermal technology, for example, are designed to be compatible with conventional circuits, DC/DC converters need to be optimized for low-voltage inputs.
Sensor nodes for the Internet of Things often need to placed well away from a reliable power source but operate for many years. Although long storage-life batteries provide one option for powering these devices, an increasingly viable alternative is the use of environmental energy harvesting, using sources such as light, vibration and temperature differentials.

Micrel’s family of low-profile step-down power modules integrates a synchronous buck regulator with an inductor into a 2.5×3×1.1-mm QFN package for the 1-A MIC33163/33164 and a 2.5×3×1.9-mm QFN package for the 2-A MIC33263/33264. The modules offer 100% duty cycle operation and accommodate an input voltage range of 2.7 V to 5.5 V.
