Humidity sensor using 8051


by circuitstoday.com:

This project is about a simple humidity sensor based on 8051 microcontroller. Humidity sensor is also called hygrometer. This circuit can sense relative humidity (RH) from 20% to 95% at an accuracy of 5%. The humidity information is displayed on a 16×2 LCD display. A relay is also provided which is set to be active when the humidity crosses a certain trip point. The circuit is mains operated and it is very easy to install. DHT11 is the humidity sensor used here. The details and working of the DHT11 humidity sensor is given below.

3D Print the Ultimate Helping Hands for a PCB Workstation


by Giuseppe Finizia @ makezine.com:

I am the Senior Analyst of the Electronic Forensics Unit of the Carabinieri (Italian Military Police) and I deal with technical investigations on seized electronic devices. I spend most of my day in a well-equipped electronic laboratory, but I was lacking a tool for performing technical assessments on printed circuit boards (PCBs). I needed a way to secure small boards on my workbench and place multiple probes across the board for acquiring data from a circuit memory, analyzing an I2C or SPI communication bus using a logic state analyzer, and much more.

Multifunction biosensor/vital signs monitor for wearables, from ams


by Graham Prophet @ edn-europe.com:

Sensor and mixed-signal IC specialist ams (Graz, Austria) has applied optical detection techniques to produce a sensor capable of accurate heart rate measurement; the company says its device is the first “total solution for 24/7 heart rate measurement for wearables”.

AS7000 is the first in what is to be a family of health/fitness solutions from ams, for wearable devices. The AS7000 solution incorporates a highly integrated optical sensor module accompanied by software to provide the highest accuracy optical heart rate measurements (HRM) and heart rate variation (HRV) readings, backed by opto-mechanical design-in support. The 24/7 reference is to indicate that ams intends the device for products that are worn continuously, rather than (for example) only during periods of exercise.

DIY Motorized Combo Lock Cracking Device

Combo Breaker is a motorized, battery powered, 3D printed, Arduino-based combination lock cracking device. It is portable, open source, 3D models provided, and exploits a new technique I’ve discovered for cracking combination locks in 8 attempts or less, but in an even more exciting, automated fashion.

Solar Cells Made Obsolete – 3D rectennas aim at 40-to-90% efficiency


R. Colin Johnson @ eetimes.com:

PORTLAND, Ore.–Now before you get all excited by the headline, which is not click-bait according to the researchers, a new kind of nanoscale rectenna (half antenna and half rectifier) can convert solar and infrared into electricity, plus be tuned to nearly any other frequency as a detector. The invention was made at Georgia Tech (Atlanta) and peer-reviewed in today’s issue of Nature Nanotechnology.

Right now efficiency is only one percent, but in the paper (DOI: 10.1038/nnano.2015.220) professor Baratunde Cola and colleagues at the Georgia Institute of Technology (Georgia Tech, Atlanta) convincingly argue that they can achieve 40 percent broad spectrum efficiency (double that of silicon and more even than multi-junction gallium arsenide) at a one-tenth of the cost of conventional solar cells (and with an upper limit of 90 percent efficiency for single wavelength conversion).

Samsung launches industry’s first 12Gb LPDDR4 DRAM


by Samsung:

Samsung Electronics announced that it is mass producing the industry’s first 12-gigabit (Gb) LPDDR4 (low power, double data rate 4) mobile DRAM, based on its advanced 20-nanometer (nm) process technology.

The newest LPDDR4 is expected to significantly accelerate the adoption of high capacity mobile DRAM worldwide. The 12Gb LPDDR4 brings the largest capacity and highest speed available for a DRAM chip, while offering excellent energy efficiency, reliability and ease of design – all essential to developing next-generation mobile devices.

One case – over 100 possibilities of usage


We speak about the practical case CTK110EU full of high quality CrV tools sufficient for majority of common operations.

CTK110EU tools set might be easily called as “all-in-one”. Naturally, such all-in-one solution won´t help in all situations which we may face at production or servicing, but very probably it is more than suitable for a vast majority of common operations. Perhaps the biggest advantage of this solution is, that everything is clearly packed in a practical carrying case. So if you have such a case of tools by your hand – in a workshop or car, it´s very probable, that it will be your first choice for any situation.Why just the CTK110EU? Because it is a case from a renowned producer Crescent (a member of APEX tool group, where also the Weller belongs) and contains 110 tools of a guaranteed quality (CrV/ CrNi) and also ergonomically on a very good level.
All, what the case contains can be found in the CTK110EU datasheet.

Laser Data Transmission

Lasers have been one of the essential technologies used in industries. It is realized that light outperforms radio in terms of speed and density. It has been used for communications whether in scanning barcodes, reading CD’s and DVD’s. This design is a simple data transmitter that uses a DIP switch to support the transmission of data over a transmission medium. This switch withstands extreme shock, vibration, temperature and altitude.

The circuit works when bits are sent across the receiver using an amplified light where signal is received by a phototransistor. The voltage is converted to digital signal that will be read by the receiver. The one shot multivibrator on both ends used to send 8 clock pulses and will received at the receiving end. The first bit starts the clock and the second bit goes to Serial In/Parallel out IC. Pulse triggering occurs at a particular voltage level and is not directly related to the transition time of the input pulse. Once fired, the outputs are independent of further transitions of the input.

Laser data transmission has various applications that can send voice and video data. This can be made more portable so that users can easily bring the device whenever possible. The device can be easily constructed and integrated to other electronic devices and may be used as a fundamental circuit for electronic finder/trackers.
