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.

To refill the DREMEL VersaTip, it´s advisable to use a clean liquid buthane. Detailed description will provide you the VersaTip Instruction Manual.

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 33163by Susan Nordyk @ edn.com:

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.

This project is an open source (hardware & software) DDS generator, based on: smart TFT module, AD9834, LM7171 fast amplifier. The homemade function generator is a quite common project on the internet. We can find different ways to do it:

– The quick & dirty way based on a DDS module bought on eBay
– The analog version based on a MAX038 / XR2206
– The “clean” way based on a FPGA and a fast DAC (e.g. http://www.circuitben.net/node/14)
– The software way (e.g. Arduino + R/2R DAC)

From my side, I wanted a small one which could fits my needs without being too expensive. According to me, such generator should at least:

– Be easy to use
– Output a signal from 1Vpp to 10Vpp (+/-5V), from 0 to 1MHz
– Have a low profile
– Without electric hazard (shall work on a 12V DC)

Researchers at Tohoku University in Japan have developed a new low-cost flat panel light source that could pioneer a new generation of brighter, cheaper and greener lighting devices to rival LEDs. The device uses arrays of highly conductive carbon nanotubes to deliver evenly-distributed illumination with high efficiency and a power consumption as low as 0.1 Watts – about 100 times lower than that of light-emitting diodes.

RWXBioFuge preview v1.0

by PieterVanBoheemen:

Centrifugation is a powerful method for isolation of compounds such as DNA, proteins, oil or membrane vesicles from a complex mixture. The RWXBioFuge was designed to bring this powerful tool into the hands of labtechnicans, scientists, hackers, makers, diybio-ers and those who cannot afford to procure A-label equipment in low-resource settings.

It may also be used as an educational project to teach some fundamental principles of physics, chemistry, biology and electronics hands-on. Apart from an assembly guide, this documentation also includes 7 instructions for demonstration experiments and science classes.

This Application Note from Microchip provides a reference design for building a non-invasive blood pressure meter using the PIC24FJ128GC010 microcontroller and MCP6N11 instrumentation amplifier. [via]

A digital blood pressure meter measures systolic and diastolic pressures by oscillometric detection. Microchip’s digital blood pressure meter demo can measure blood pressure and pulse rate during inflation. The Measurement While Inflating (MWI) principle reduces overall measuring time, which in turn reduces discomfort caused by the pressure in the cuff.

First ever affordable 5axis multi-fabricator that brings most advanced fabrication right to your desk:

We’ve designed machine that combines multi- fabrication methods: 5axis milling being one of them. 5AXISMAKER is a machine versatile enough to fabricate most advanced design prototypes in readily available material while on your desktop right next to you.

Being an alumni of Architectural Association we’ve had an access to most advanced fabrication tools in the world. Yet there is no desktop prototyping machine that has versatility to replicate this technology.

Our company has been initially found as design and fabrication practise, and after years of working with wide range of designers from different fields it has become clear that one should have an instant access to a pallet of prototyping tools. We wanted same machine to include a set of tools like CNC mill, touch-probe, 3d printer, wire-cutter and have a potential for further add-ons.
