Description

Circuit diagram like in figure 1 above is Circuit Diagram Fire Alarm using Thermistor and NE555. According Circuitstoday site describe that many fire alarm circuits are presented here,but this time a new circuit using a thermistor and a timer to do the trick. The circuit is as simple and straight forward so that, it can be easily implemented. The thermistor offers a low resistance at high temperature and high resistance at low temperature. This phenomenon is employed here for sensing the fire.

The IC1 (NE555) is configured as a free running oscillator at audio frequency. The transistors T1 and T2 drive IC1. The output (pin 3) of IC1 is couples to base of transistor T3 (SL100), which drives the speaker to generate alarm sound. The frequency of NE555 depends on the values of resistances R5 and R6 and capacitance C2. When thermistor becomes hot, it gives a low-resistance path for the positive voltage to the base of transistor T1 through diode D1 and resistance R2. Capacitor C1 charges up to the positive supply voltage and increases the the time for which the alarm is ON. The larger the value of C1, the larger the positive bias applied to the base of transistor T1 (BC548). As the collector of T1 is coupled to the base of transistor T2, the transistor T2 provides a positive voltage to pin 4 (reset) of IC1 (NE555). Resistor R4 is selected s0 that NE555 keeps inactive in the absence of the positive voltage. Diode D1 stops discharging of capacitor C1 when the thermistor is in connection with the positive supply voltage cools out and provides a high resistance path. It also inhibits the forward biasing of transistor T1.

The Devil Is in the Detail of Deep Learning Hardware by James Morra

Robotronicdiagram. -This is one information about the industrial automation in this time with the title The Devil Is in the Detail of Deep Learning Hardware that written by James Morra and published in Electronic Design site.

To identify skin cancer, perceive human speech, and run other deep learning tasks, chipmakers are editing processors to work with lower precision numbers. These numbers contain fewer bits than those with higher precision, which require heavier lifting from computers.

Intel’s Nervana unit plans to release a special processor before the end of the year that trains neural networks faster than other architectures. But in addition to improving memory and interconnects, Intel created a new way of formatting numbers for lower precision math. The numbers weigh fewer bits so the hardware can use less silicon, less computing power, and less electricity.

Intel’s numerology is an example of the dull and yet strangely elegant ways that chip companies are coming to grips with deep learning. It is still unclear whether ASICs, FPGAs, CPUs, GPUs, or other chips will be best at handling calculations like the human brain does. But every chip appears to be using lower precision math to get the job done.


Still, companies pay a surcharge for using numbers with less detail. “You are giving up something, but the question is whether it’s significant or not,” said Paulius Micikevicius, principal engineer in Nvidia’s computer architecture and deep learning research group. “At some point you start losing accuracy, and people start playing games to recover it.”

The master timing control circuit for most electronic applications is a precision signal source. For digital applications, it’s an accurate clock. In RF applications, it’s a carrier source for a transmitter or a local oscillator (LO) for a receiver. And if frequency modulation (FM) is involved, a modulator and demodulator are needed along with a carrier source.

In all of these cases, a phase-locked-loop (PLL) frequency synthesizer is an excellent choice. It provides not only the precision and accuracy needed, but also a flexible way to change frequency.

PLL 101


Just as a review, a PLL synthesizer is a closed-loop controller with feedback (Fig. 1). A voltage-controlled oscillator (VCO) generates the output signal. Frequency is determined by an LC resonant network, but controlled by a dc input voltage derived from a phase detector and a low-pass loop filter.

  2. LM555 IC
  3. LM7812 IC
  4. LM358 IC
  5. Transformer
  6. Capacitors

Description

Circuit diagram like in figure 1 above is Circuit Diagram Automatic Battery Charger using LM317 and LM555 IC. According Electronichub site describe that an Automatic Battery Charger Circuit for sealed lead acid batteries is mentioned in this project. It is a pulsed-charger type circuit which helps in increasing the life of batteries. The working of this circuit is explained below.

LM317 acts as voltage regulator and current controlling device. The 15V Zener diode is used to set the LM317 to supply 16.2V at output in the absence of load. When the 2N4401 is turned ON by the output of 555, the ADJ pin of the LM317 is grounded and its output voltage is 1.3V.

LM358 acts as a comparator and voltage follower. LM336 is used to supply a reference voltage of 2.5V to non-inverting terminal (Pin 3) of LM358. A voltage divider network is used to supply a portion of battery’s voltage to inverting terminal (Pin 2) of LM358.

When the charge in the battery reaches 14.5V, the input to inverting terminal of LM358 is slightly greater than 2.5V at Pin 3 set by LM336. This will make the output of 555 go high.

As a result Red LED glows and the transistor is turned on. This will ground the ADJ pin of LM317 and its output falls to 1.3V.

Communities realizing future of energy lies in solar power by Greenfield Recorder

Robotronicdiagram. - This is one of the solar power information for you in this time that titled with Communities realizing future of energy lies in solar power and published in Greenfield Recorder.

Brief thoughts on some of the events making news from around Franklin County and the North Quabbin area:

The state is investing in solar power, big and small in Franklin County, continuing to do our part to power the world with renewable energy.

On the small side, Hawley will be using part of a $136,920 Green Communities grant to buy and install a 10-kilowatt solar panel system on the town’s Highway Garage, which should save the town money in the long run.

On the large side, the state is investing $545,000 in Greenfield to install a 436-kilowatt solar canopy over the Franklin County Jail and House of Corrections parking area. Same deal. Once operating, the panels should save the Elm Street jail operating expenses that we hope will be redirected to programs for inmates.

Pool time may be coming after all

Buckland has one wonderful benefactor — who has donated $500,000 anonymously for the construction of a new swimming pool for the Buckland Recreation Area.


The old popular, but leaky, concrete pool was removed this past year with no firm plans to raise the million dollars or so needed to incorporate a new one into envisioned renovations to the town’s recreation area off Route 112.
