Arduino UNO R3 mini laser cutter:
A few years ago I saw an Instructable where Groover had used a pair of DVD-RW drives to make a pocket laser engraver. Inspired by the idea, driven by the recent purchase of a full-sized 50 watt CO2 laser cutter, and roused by the launch of the Microcontroller contest I took the decision to have a crack at making my own mini laser engraver.

Inrush current, effective power, power factor, harmonic distortion, … all these and other parameters handles CM8 with easiness.
Clamp multimeters are often used mainly thanks to their ability to measure AC (and even DC) current even without a disconnection of a wire. But it´s only one basic feature, which more sophisticated devices can use even for another purposes, like comfortable measuring of power and power factor. Benning CM8 is a device able to provide detailed information regarding power conditions in a measured circuit and measure much more than usual clamp meters, for example:
● measuring of inrush current
● measuring of effective power in 4 ranges – 4/40/400/600 kW + calculation of a power factor in a full range -1,00…0…+1,00
● VAC true RMS in a frequency range of 45-500Hz, high accuracy up to a crest factor of 3
● harmonic distortion with 0,1% resolution and sensitivity up to 25-th harmonic (ACV, ACA)
● measuring of DC current up to 600A (0.1A resolution)
It can be said, that Benning CM8 is a device, with which it´s possible to check even large circuits and for example find possible source of defects and similar. Thanks to a measurement of inrush current it´s able to give a real information about a load of a circuit and thus for example to give an information, whether it´s possible to add another device into a given circuit etc.
Detailed information about the CM8 will give you the Benning CM8 user guide and an overview of Benning measuring and testing devices.

Saelig Company, Inc. (www.saelig.com) has introduced the new CGM-101 CircuitGear Mini – a unique, low-cost PC-based instrument which provides the features of six devices in one USB-powered compact box: 2-channel 11-bit 2MSa/sec 200kHz oscilloscope, 2-channel spectrum analyzer, 2MSa/s 8-bit arbitrary-waveform/standard-function generator with 8 digital I/O lines. It also functions as a network analyzer, and a PWM output source – all for less than $100! The oscilloscope and waveform generator can also work together to form a vector network analyzer. The USB interface allows the recording, output and printing of all waveforms or even updating the firmware as new features become available.
The CGM-101 CircuitGear Miniʼs Oscilloscope capability provides a two-channel 11-bit 20mV/div to 5V/div
(+/-0.25Vp-p to +/-25Vp-p with 1X Probe; +/250Vp-p with 10X Probe) 200kHz basic scope, also offering sophisticated marker measurements, and triggering (normal, auto, single-shot and pre-trigger) with a time-base adjustable from 500ns/division to 20s/division. A 1k sample/channel data buffer allows pre-trigger signal or “strip-chart” viewing. X-Y Plot, spectrum analysis, and waveform math are also included. The two-channel FFT spectrum analyzer offers marker measurements, and, when used with the internal signal generator, displays Bode plots and performs vector network analysis, showing gain and phase values in real-time.
The CircuitGear CGM-101ʼs Signal Generator is an 8-bit 0Hz to 200kHz signal source, offering sine/square/triangle/sawtooth waveforms to +/-2.75V, as well as being capable of outputting arbitrary or preloaded waveforms like ECGs. Connecting the generator signal to a circuit under test enables measurements with the oscilloscope and/or spectrum analyzer.
The compact (4.6″ x 3.1″ x 0.95″ – 117 x 79 x 24mm) USB port-powered CGM-101 CircuitGear Mini also offers eight TTL I/O lines for PWM or other uses such as trigger in/out. The visual interface software provided makes control and display of information very intuitive, and users of bench-top instruments will immediately feel comfortable with the on-screen controls. The oscilloscope, generator, and digital I/O are operated from a custom open-source Tcl/Tk software GUI included with the hardware, which runs under Windows, Linux, Unix, and Mac operating systems. Because the software is Open Source, the code can be read and even added to or customized. The command set is compatible with MATLAB®, LabVIEW and virtually any programming language.
Aimed especially at teaching establishments, project-based electronics lab teaching materials are also available for use with CircuitGear CGM-101. Ideal for labs, education, and any engineerʼs toolbox, it is available now from stock from Saelig Company, Inc. Fairport NY at only $99.95. 1-888-7SAELIG email@example.com www.saelig.com.

It´s possible to receive the latest technical and safety datasheets of Kontakt Chemie products comfortably into your e-mail box.
As chemical agents belong to a highly regulated segment (on-going REACH) process), it´s necessary that you always had the actual version of technical- and mainly safety datasheets for agents which you use. Especially for larger companies using a many chemical agents it´s a considerable load – to watch legislative changes and to search for the latest version of documents.
That´s why company CRC – producer of Kontakt Chemie sprays, brings a useful and free service „My CRC“. By means of „My CRC“ the end user has ensured the 100% latest documentation in case of legislative changes as is the hazard classification or changes of European law. These changes don´t affect the product production or its availability but the actual documentation version is vital from reason of possible criminal responsibility.
After a simple registration on the http://www.crcind.com/crc/ – website – by clicking on the „My CRC“ logo, you´ll receive an e-mail with login. In the next step after signing-in (by clicking on the “My CRC” logo) select a language for required documents – in the left bottom part of page. In the upper portion of the website you can select a country and language for work on this web. If the given country is missing, we recommend you to choose „Others/ English“. The documents are in the alphabetical order and you can check the column in the right at every document, which you´re interested in. Finally, after clicking the „My selection“ button, it´s possible to choose whether you wish to receive on your e-mail these documents (immediate e-mail with links to these documents) or you wish to receive only changes/ updates of these documents (if occur in the future).
We believe, that this function will make your work more pleasant and easier. In case of questions, please contact us at firstname.lastname@example.org.

Hardware/software combo can create professional schematics from undocumented PCBs
Fairport, NY. The RevEng System is a remarkable reverse-engineering hardware tool for creating professional quality circuit schematic diagrams from a sample PCB that lacks documentation. The RevEng System consists of a PC-controlled continuity-detecting hardware system, RevWin control software, and EdWin, a fully featured CAD package. RevEng ʽlearnsʼ the connectivity of the sample circuit, producing a netlist of the components and connections for importing into EdWin software, resulting in professional quality circuit diagrams.

This DIY Solder Paste dispenser is an easy project to build, so I thought I would share the details a bit with everyone! When possible I like to build my own tools, it makes sense especially when you have most of the parts on hand. There are a lot of tools that are just yak shaving experience, but fortunately this isn’t one of them!

Our friend Vassilis decided to build his own manual Pick & Place machine to facilitate his work with 0402 SMD and other fine pitch parts. He used plywood, a pen microscope and a vacuum pump to build this dirty cheap Pick and Place manual machine:
If you are dealing with tiny SMD parts (e.g. 0402 resistors and capacitors), a manual pick and place machine is a helpful piece of equipment for prototyping and small-batch manufacturing. On the other side, traditional SMD placement using precision tweezers not only requires an ultra-steady hand but also becomes a tiresome drill, especially when working long hours upon fine-pitch PCB footprints.
