Electronic Circuits on Circuit Exchange International (CXI) VPT 7 VPT 8 by HC Gilje, released may 2018. Video Projection Tool (VPT) is a free multipurpose realtime projection software tool for Mac and Windows. VPT 7 was downloaded over 100000 times, so in spite of a lot of other options available VPT still is popular. Among other things it can be used for projecting mapping on complex forms, adapt a projection to a particular space/surface, combine recorded and live footage, for multiscreen HD playback, for interactive installations using arduino sensors or camera tracking ++. VPT is very flexible in terms of control, with presets and a built in cue list, as well as control over almost every single parameter using OSC, midi, serial communication, built in LFOs and ArtNet. It also supports syphon (mac) and spout (windows) for sharing video streams between applications. VPT 8 is recommended for mac OS 10.12 or later and Windows 7 and 10 (although VPT 7 works great on Windows 7). and yes, it is still FREE! VPT 8 has a lot of under-the-hood changes. extras:

LIME ART GROUP – Interactive Video Mapping 101 - 200 Transistor Circuits e-book. It contains a further 100 circuits, with many of them containing one or more Integrated Circuits (ICs). It's amazing what you can do with transistors but when Integrated Circuits came along, the whole field of electronics exploded. IC's can handle both analogue as well as digital signals but before their arrival, nearly all circuits were analogue or very simple "digital" switching circuits. Let's explain what we mean. The word analogue is a waveform or signal that is changing (increasing and decreasing) at a constant or non constant rate. But let's crawl before we walk and come to understand how to interface some of these chips to external components. Colin Mitchell TALKING ELECTRONICS. To save space we have not provided lengthy explanations of how the circuits work. KIT OF PARTS Talking Electronics supplies a kit of parts that can be used to build the majority of the circuits in this book. MORE INTRO There are two ways to learn electronics.

Capacitor as it äppears" to a high frequency signal: (high or low) impedance? Inductor as it äppears" to a low frequency signal: (high or low) impedance? Inductor as it äppears" to a high frequency signal: (high or low) impedance? Capacitor as it äppears" to a low frequency signal: high impedance. Capacitor as it äppears" to a high frequency signal: low impedance. Inductor as it äppears" to a low frequency signal: low impedance. Inductor as it äppears" to a high frequency signal: high impedance. Challenge question: what does a capacitor äppear" as to a DC signal? Notes: Ask your students how they arrived at their answers for these qualitative assessments. Question 2: Question 3: Hint: this only requires a single component per tweeter!

LC meter, Coil Capacitor meter This LC meter circuit can measure coils and capacitors. When Lx or Cx is connected in the circuit the oscillator frequency will decrease and this decrease is measured by a frequency-voltage converter build with T3 and T4. To adjust this lc meter circuit with P1 and P2. LC meter precision is 3%. Scale calibration can be achieved with this formula: ni = nm(1 – fr)/(1 – fc) where ni is number of divisions measured on the scale, nm = total number of division of the scale, fr = relative frequency, fc = the smallest relative frequency measured. The total power consumption is 12mA at 12V when the LC measurement occur. Coil Capacitor meter schematic components
pH measurement : ELECTRICAL INSTRUMENTATION SIGNALS A very important measurement in many liquid chemical processes (industrial, pharmaceutical, manufacturing, food production, etc.) is that of pH: the measurement of hydrogen ion concentration in a liquid solution. A solution with a low pH value is called an "acid," while one with a high pH is called a "caustic." The common pH scale extends from 0 (strong acid) to 14 (strong caustic), with 7 in the middle representing pure water (neutral): pH is defined as follows: the lower-case letter "p" in pH stands for the negative common (base ten) logarithm, while the upper-case letter "H" stands for the element hydrogen. The logarithmic pH scale works like this: a solution with 10-12 moles of H+ ions per liter has a pH of 12; a solution with 10-3 moles of H+ ions per liter has a pH of 3. The design and operational theory of pH electrodes is a very complex subject, explored only briefly here. Here is an illustration of the measurement electrode's construction.
