![]() If you try to create these mini electronic projects with small circuits. Because cheaper and faster than buying KITS. Most simple electronic circuits, we assemble on a universal PCB Board. It is not a failure, but it is another way of learning. If the project does not work, we learn the solution. Also, study homeschooling the same as us.Some are over 60 years old and love Electronics too. EEE(Electrical and Electronics Engineering) students.ECE(Electronics and Communication Engineering).For Arduino is so expensive for only LED blink. Which is better? For me, Easy and cheap is better. You have many choices to do.įirst, transistors circuit. Like diodes, transistors, digital electronics ICs and more. I like small or mini-projects using simple and low cost. So, I will show you the top 100 list of projects.

Once you can control a load with a voltage, the next step is to program it. However, it does mean you have to carefully select the op amps to have very low input offset voltage as even 1 mV is more than a 1% error at this level. Using a small current-sensing voltage is a good thing as it leaves most of the voltage for the load. Each millivolt into the comparator translates to an additional 1.33 A through the load. That voltage feeds a comparator which generates the gate voltage after looking at the input control voltage. A very small source resistor develops a voltage based on current (only 75 mV for a 50 A draw). The FETs accept a voltage on their gates that sets them to look effectively like a resistor that varies with the voltage. So you are going to need to carry some heat away. Keep in mind that’s 120 watts–more power than a common incandescent light bulb. So if the load is set to 10 A and you connect it to a 12 V source, the MOSFET should look like a 1.2 ohm resistor. You can see a demo in the video below.Īn electronic load is essentially a load resistor you can connect to a source and the resistance is set by an input voltage. Together, they can sink 400 W and can handle a peak of 1 kW for brief periods. The result was a two-channel beast that can handle 50 A per channel. Had some extreme MOSFETs (IXTK90N25L2) and decided to create a high current electronic load.
