I request you toadd How Things Work section tothe magazine. The topics can rangefrom daily-use electronic devices totelecommunications. It would be ajoy to read such articles.Ismail TaibaniThrough emailFrom Facebook: EFY’s Electronics Design CommunityI am very excited that my colleague Kaustubh is giving a talk on ‘Build a Smarthome UsingRenewable Energy Micro-Grid with Existing Infrastructure’ at this year’s eRocks.Kaustubh came to know about FluxGen’s work in renewable energy systems throughan article inElectronics For Youon solar energy systems. He applied for the position ofintern at FluxGen after reading that article as he was very keen on working in solar domain.And now, as chief engineer of FluxGen, he will be representing us and showcasing ourwork at the conference hosted by EFY!Ganesh ShankarWooo… This post takes me about two years back. When I Googled “employment insolar,” I happened to go through an article inElectronics For You.Certainly, this articlehelped me become a part of the most enthusiastic engineers I have ever met in my life.Kaustubh KarnatakiI am working on an Internet of Things (IoT) project using Intel Edison. I wish to publishit inEFYmagazine.Rushiraj JawaleEFY.Please send complete details of the project to editsec@efy.inFor editorial guidelines, you may refer toefymag.com/Guidelines_for_EFY_authors.docRC Boat ModellingI want to purchase the kit mentionedin ‘Basic Guide to Radio-ControlledBoat Modelling’ DIY article pub-lished in August issue. Is it availableonline?Dr R.S. GadDepartment of ElectronicsGoa University, GoaThe author T.K. Hareendran replies:Here are some links where you canpurchase radio-controlled boat kitsand their spare parts:www.rcbazaar.com/category.aspx?categoryid=259www.rcracinghobbies.com/boats.htmlwww.thehobbyshop.inYou can also increase the numberof bits, but that is a bit more compli-cated. If you need more than an 8-bitDAC, I suggest you use monolithicDACs. Perhaps, we could address thatin a separate article.‘Spot An Error’ Award WinnerIn ‘Lift Indications’ DIY article published inSeptember issue, the symbol for VR1 iswrong. It should be preset symbol. Resetpins of IC2 and IC3 should have active lowsigns, with a bar on each reset pin.Vijay KakulThermocouple TutorialI found some mistakes in ‘Thermo-couple Tutorial with Arduino Inter-facing’ DIY project published in Sep-tember issue. Those are listed below:1. Transformer (X1) rating isgiven as 9V-0-9V in the PCB layoutbut 12V-0-12V in Parts List.2. CON2, CON3 and CON4 arenot included in Parts List. CON2 pinpitch should be mentioned as it isdifferent from other connectors.3. It is mentioned ATmega32with Arduino UNO but it should beATmega32P.4. On page 120, you have ex-plained about Arduino UNO boardwith 13 digital pins instead of 14digital pins.5. Arduino UNO board powersupply should be provided by a USBport or Vin (9V-12V). In this circuit,Arduino UNO is being powered by7805, which is wrong. It will shortLow-Cost 6-Bit DACLet me know if there is a way tomodify the ‘Low-Cost 6-Bit DAC’ cir-cuit published in January issue for a4-bit or a 16-bit DAC.Sreeram P.R.Through emailThe author Petre Petrov replies:You can easily reduce the number ofthe bits as explained below:Let us say, LSB = bit D0, MSB= bit D7Remove the LSB (D0) and youget a 7-bit DAC; remove the LSB(D0) and D1, you get a 6-bit DAC;remove D0, D1 and D2 and you geta 5-bit DAC; remove D0, D1, D2 andD3, you get a 4-bit DAC and so on.6November 2015 | electroNics For Youwith Arduino UNO’s own 5V regula-tor.Gunjan MaheshwariThrough emailThe author Ronie Adhiraaj Ghoshreplies:1. PCB layout was designed by EFYLab. However, any transformer with-in 9V to 12V will work.2. Connectors are for modularityand different designers may chooseto construct differently. That is theease of working on Arduino.3. Arduino UNO used in the pro-ject was based on ATMega328, notATmega32P.4. It should be 14 digital pins. It isa slip of pen.5. USB supply is not used in thisproject. In my board I have usedan external 7805. Like mentionedearlier, different people use differentdesigns.www.eFYmag.comQ&AThings YouWanted to Know!Q1.What is the difference betweena transformer and a coupledinductor?A1.A. SamiuddhinThrough emailA transformer is a static elec-trical device that transferselectrical energy between two ormore circuits through electromag-netic induction. Depending on how atransformer is designed, you can useit to step down or step up voltages inpower applications. It is also used forimpedance matching or for isolatingone part of a circuit from another.less than 32 input/output functionsand usually feature an all-in-one de-sign that integrates an input module,output module and a logic moduleinto a single unit that looks like abrick or a block.A PLC represents a universal con-troller. It can be used for different ap-plications and via the program installedin its memory. It provides the user witha simple means of changing, extendingand optimising control processes.Some applications of PLCs are:Manufacturing processes.Lead-acid battery plants, extruder automa-tion factories and silo-feeding controlsystemsTravel industry.Escalator op-erations, monitored safety controlsystems and lift operationsAerospace.Water tank quenchingsystemsPrinting industry.Offset Webpress print register control systems andmulti-stage screen washing systemsTextile industry.Industrial batchwashing machine control systems andclosed loop textile shrinkage systemsenergy?Q3.What is solar the solarWhichcomponent ofpanelis used for conversion of solar energyto electrical energy?Satyajit SamalThrough emailSolar energy is the radiationand heat received from theSun. The radiation is converted intoelectrical energy with the help of solarpanels, which are made of solar cells.A solar cell is a semiconductor de-vice (p-n junction) that converts solarenergy directly into electrical energyusing photovoltaic effect. A cell is asmall disk of a semiconductor likesilicon. Multiple disks are attached toform a circuit using a wire. As sun-light strikes the semiconductor, lightis converted into electricity that flowsthrough the circuit. As soon as thelight is removed, the solar cells stopproducing power.Answers compiled by EFY Lab engineers.
