The functional generator is a device that would have any better equipped electronic lab should have a cialis cost not so frequently used gadgets, but when you need it, we certainly appreciate its convenience. Here is the procedure of the scheme, which was published in the magazine Everyday Practical Electronics – 2000g – nr. 07. The heart of this device is 20 20mg cialis generic only pill an integrated circuit MAX038 precision function generator that is adjustable for a triangular, square, or sine wave signal. Frequency range is quite wide from 1Hz to 10MHz.
PIC16F877 microcontroller control circuit with five inputs/outputs which is essential for several functions. Used to switching capacitor to generate the frequency, 50 mg viagra retail price the choice of waveform, frequency calculations and data display on the LCD. In preparing the pcb by PDF files that are attached, it is important to cheap viagra 25mg pay attention to a mistake that I made and is shown below.
After programming the PIC and all the components have been soldiered, at first is checking the validity with no case, just naked electronics. There is a photo of completed PCB with components associated with LCD display and potentiometer, power supply is brought “on the viagra prescription fill table” – just basic, raw test.
The LCD shows that everything is going according to plan. Nice to see that everything was planned is in right place. The next step is a process in which we will put in the housing, generic cialic vs cialis then follows the fun with tools for mechanical processing, drilling and CNC engraving job to the front panel. It is willingly arranged by my friend that owed me the favour, I am only reminded him that I wouldn’t forbid the pleasure of his participating in this venture.
Here’s some pics to take look at:
