Drawing Veroboard Layouts by Ron J Using Electret Condenser Microphones Winscope How to Create a Parts List From Schematic To Veroboard Parts Storage The Best Of Thomas Scarborough Thomas Scarborough, has wrote a series of electronic books. Home Made PCB's an excellent article on uC Hobby website Homebrew PCB Yahoo Group Selecting Capacitors Designing Stripboard Layouts with Inkscape by Ron J Diagnosing Faulty Capacitors 555 Timer/Oscillator Tutorial I nside the 555 timer, at fig. 3, are the equivalent of over 20 transistors, 15 resistors, and 2 diodes, depending of the manufacturer. The equivalent circuit, in block diagram, providing the functions of control, triggering, level sensing or comparison, discharge, and power output. Some of the more attractive features of the 555 timer are: Supply voltage between 4.5 and 18 volt, supply current 3 to 6 mA, and a Rise/Fall time of 100 nSec. The Threshold current determine the maximum value of Ra + Rb. The supply current, when the output is 'high', is typically 1 milli-amp (mA) or less. All IC timers rely upon an external capacitor to determine the off-on time intervals of the output pulses. Assume further that the applied voltage is 6 volts. Fig. 4-1, Change in the input pulse frequency allows completion of the timing cycle. Looking at the curve in fig. 6. you can see that it takes approximately 5 complete time constants for the capacitor to charge to almost the applied voltage.

Dynamic Tonality Free electronics projects and circuit diagrams (schematics) for hobbyists. Build your own electronic gadgets you knew i was going to make one. they are all over pinterest....(i still am not signed up for pinterest because i don't have time for one more thing but browsing is fun!) so we made one. i took a box of 64 crayons and took out the blacks and browns.i used another small box and doubled up on the good colors i liked and hot glued them to the top of our canvas. then we turned our blow dryer to hot on high. not long after you set the hair dryer by the crayons they get shiny and then the wax starts to melt! and it dries really quickly too. seriously. what could be happier than this?? GREAT project. loved it today is the first FULL day with ALL my kids in ALL day school.yeah...i am smiling as i type that. it's good. it's quiet. i am rockin' it. removing wallpaper.....making code for craft weekend stuff.....doing my hair....going to lunch..... it's all good. hooray for school!

Drawdio! How does it work? The Drawdio kit is pretty simple compared to most electronic projects. We will go through it one section at a time, please refer to the schematic Power supply The first part to understand is the power supply, which keeps everything running. The power source is a single AAA battery which is held in a plastic container that is soldered to the PCB. The Oscillator The heart of the kit is a TLC551 chip, which is a low voltage version of the famous LM555 timer chip. One of the more popular ways that '555s are used is as a 'astable multivibrator' which is another way of saying an oscillator. This system is pretty much identical to Japanese water fountains, as this video shows: Except its all with electrons instead of water molecules and capacitor C1 is the 'bucket'. f = 1.44 /(C3 * (RA + 2 * RB)) C3 = 680 pF = 0.00000000068 FRA = 10000 ohmsRB = 300000 ohm to 1000000 ohm (1 Mohm) Amplifier

IanniX How to build electronic devices on your own Building electrical devices is probably the most inexpensive engineering you can do because most electronic components are very cheap, like less than $1. How to actually build devices on your own isn't taught enough in engineering courses, so here's a quick summary of how to get started making devices like I have on my site. In this page, I kind of assume you're an engineer/scientist of some sort (or studying to be one) and that you've already had a few electrical engineering classes. If you don't know any electrical engineering, you'll obviously need to learn the basics before you can start inventing. A good place to start is the book Make: Electronics , which teaches you theory and practical knowledge of components at the same time. First, get an idea To get an idea for something cool to make, it helps to go to online stores for electronic components (Jameco.com is a good one) and look at the components they have. Also, I really recommend getting a microcontroller, like the Arduino. . .

50 Life Hacks to Simplify your World Life hacks are little ways to make our lives easier. These low-budget tips and trick can help you organize and de-clutter space; prolong and preserve your products; or teach you something (e.g., tie a full Windsor) that you simply did not know before. Most of these came from a great post on tumblr. 20. 40. Sources – muxedo task: 99 Life Hacks to make your life easier! If you enjoyed this post, the Sifter highly recommends:
