  • Flyback Transformers (FBT)

    Flyback transformers (FBT) or line output transformers (LOPT) are transformers that are designed to produce a very high output voltage (normally in the order of kilo volts) from a relatively low input voltage. Flyback is a topology that uses the flyback - also known as kickback - of an inductor

  • Re: ARC Quenching - Single-Pole Double-Throw Relay

    The implication that you are switching the taps of a transformer is a big hint. Regardless of the final load being a resistive load, on transition there will always be a reactive component. Since you are switching an AC signal, the standard practice of a Flyback diode across the inductive load will...

  • Go Analog With A Resistance-Based Calculator

    Do simple calculations with your own math box. Ralph Smith The next time you need to crunch a couple of numbers, resist the urge to grab a digital calculator. Instead, round up some variable resistors, also known as potentiometers, and wire them into an analog mathematics rig. By twisting the potentiometers' knobs and measuring the resulting voltage or resistance with a digital multimeter, you can perform simple multiplication and addition without a microprocessor in sight. MATERIALS: Digital multimeter Three 1K-ohm linear potentiometers 10K-ohm linear potentiometer LM7810 voltage regulator 0.33?F electrolytic capacitor 0.1?F electrolytic capacitor SPST on/off toggle switch Four 25/32-by-15/32-inch knobs Red binding post Black binding post Banana-to-banana cables Two 9-volt batteries Two 9-volt-battery holders 5.5-by-8.66-inch project box Roll of 22-gauge hookup wire TOOLS: Wire cutters Soldering iron Screwdriver Power drill 5/16-inch drill bit Your handy math box schematic. David Prochnow INSTRUCTIONS: Follow our schematic diagram for building a 10-volt power supply from the 7810 voltage regulator. Wire the two 9-volt-battery holders together in series by soldering a black wire from one holder to the other holder's red wire. Drill holes for the potentiometers and binding posts; you can use our schematic diagram's drilling template as a guide. Solder the remaining red wire from the joined battery holders to the red (+) binding post on the switch. Solder the remaining black wire to the black (-) binding post on the switch. Solder two 1K-ohm linear potentiometers in series to create a circuit that will help you perform simple addition. Solder one 1K-ohm linear potentiometer and the 10K-ohm linear potentiometer together as voltage dividers to make a multiplication circuit. Wire the power supply to the voltage-divider potentiometers according to our schematic diagram. Use the binding posts for collecting the black (-) and red (+) wires together. Join the series potentiometers and the voltage-divider potentiometers to the respective multimeter inputs. The voltage dividers, used for multiplication, will connect to the multimeter via the binding posts and the banana-to-banana cables. The series potentiometers, used for addition, are soldered to the multimeter's two probes. Prepare the probes by snipping them off and soldering each remaining wire to one end of the potentiometer series. Place the potentiometers and power supply inside the project box. Secure the knobs to each of the potentiometer's shafts. Mark the range of each addition circuit's knobs from 1 through 10 in a clockwise direction. Next, mark the range of the multiplication circuit's knobs from 1 through 0 in a clockwise direction. (See the photo above for guidance.) Switch the multimeter's ohmmeter to 2,000 ohms for addition, and calculate sums using the series potentiometers' knobs. For multiplication, use the multimeter's voltmeter (set to 20 DC volts) and measure the product of the voltage-divider potentiometers' knobs. OPERATION: Two modes are used on the multimeter. The ohmmeter displays the series potentiometers' sums, and the voltmeter displays the voltage-divider potentiometers' products. Addition: Set up the multimeter for addition calculations by connecting the red probe wire to the V?mA (+) input and the black probe wire to the COM (-) input on the multimeter. Turn on the multimeter and set its selector dial to its ohmmeter function with a setting range of 2,000 ohms. Rotate each knob on the addition potentiometers, and watch the sum on the multimeter display. Multiplication: Set up the multimeter for multiplication by connecting the red banana-to-banana cable to the V?mA (+) input and the black banana-to-banana cable to the COM (-) input on the multimeter. Plug the other end of each cable into the matching-color binding post. Turn on the multimeter, move its selector dial to the voltmeter function, and set the range to 20 volts. Turn on the SPST switch. (Note: This switch sends 10 volts of DC power through the voltage-divider potentiometers.) Turn each multiplication potentiometer and see the product on the multimeter display. Notes: There are two noteworthy features about the multiplication function of the analog calculator: The products are decimal fractions. This is because the potentiometers act as voltage dividers. For example, the first potentiometer divides the reference voltage (i.e., 10 volts DC) in half, which is equivalent to multiplying the reference voltage by 0.5. Similarly, the second potentiometer multiplies the first product by 0.5. Therefore, if each potentiometer is placed at its halfway point, the multimeter will display a product of 2.50, or ((10 * 0.5) * 0.5) = 2.50. The second feature of the analog calculator's multiplication function is the presence of an obvious calculator error. Can you spot it? As the two 9-volt batteries begin to lose power, the resulting products will be lower than you would expect to see. For example, with both potentiometers set to 1, the anticipated multimeter display would be 10 volts. As the batteries age, however, the multimeter might display 9.55 volts with both potentiometers set to 1. Therefore, our calculation would be: ((9.55 * .5) * .5) = 2.39.

  • New CadSoft EAGLE update brings an enhanced design environment, increased flexibility and cost savings for customers

    CHICAGO – PCB design solution vendor CadSoft Computer, a Premier Farnell company, has today launched Version 7 of its award winning EAGLE PCB software. The update to the popular software brings a modern design environment with increased flexibility, enabling users to develop custom schematics using commercial standard software at a fraction of the cost. New features include an enhanced autorouter with significantly less transition points, resulting in more cost-effective and efficiently routed PCBs that require fewer manual interactions. The new autorouter also enhances productivity and performance by utilizing multi-core machines, running each routing variant on its own processor simultaneously. Users will benefit by having multiple configurations of the same routed board to choose from, and can use it to select the best outcome for his design. Version 7 supports larger design teams and more complex designs by enabling large schematic designs to be organized into small functional blocks, which can be assigned to different team members and then easily integrated when complete. This type of hierarchical methodology has significant advantages, giving large organizations a “global view” of the functional blocks of the project to make it easier to locate and change aspects of the schematic or layout. Enhanced license management features have also been introduced to protect customers’ software investment, while enabling single-user licensors to install the software on up to two devices. For multi-user license owners it will be easier to manage the seats from a license server with better protection of the software. EAGLE Version 7 also provides a new ULP to export IDF files. A basic model with placeholders for the 3D models of all components can be exported, to be used for preliminary checking. A comprehensive 3D model can be created with Simplified Solution’s “IDF-to-3D” tool which will be available in the CadSoft web shop later this summer. “CadSoft EAGLE v7 offers greater flexibility than ever before for design teams, with new capabilities that extend the software to more complex design within larger organizations,” said, Thomas Liratsch, Managing Director at CadSoft. “This means we can support more customers through each step of the design process, providing the tools that enable engineers to pull the raw components of any electronics system together, whether they are starting out in the industry or are experienced board-makers.” The latest version of EAGLE is now available to download here. About CadSoft CadSoft Computer GmbH and CadSoft Inc. are part of Premier Farnell plc., one of the world’s leading distributors of electronic components, products and services. CadSoft specializes in the development of the popular CAD-Software EAGLE used by design engineers worldwide for over 25 years.
