![]() 64 motor speeds for smooth speed control.Accurate software PWM with rates between 7.6kHz and 2kHz.Accurate throttle pulse width measurement.Slow start to protect gearboxes (or fast start if desired).Programmable throttle response curves with two sample curves.Variable rate PWM output to reduce noise a low speeds and increase efficiency at high speeds.Low voltage cutoff, stops motor on low battery voltage.Signal loss stop, stops motor on loss of valid signal.Safety startup, requires throttle be off to arm ESC.This ESC design offers the following features: This design built with standard components weighs approximately 25gms – see below. The DIY ESC is probably going to be heavier than the SMT based commercial ESCs.You may also need to select some components for this design based on what is available to you at reasonable cost. Purchasing items such as MOSFETs on a one-off basis is relatively expensive.Just the time taken to build the ESC is worth something, perhaps you would prefer to spend if flying! There may be very little financial advantage if you have access to reasonably priced ESCs. ![]() Modern commercial units with all SMT parts have a high mechanical reliability. Reliability of the BEC (and to some extent the ESC) is an important safety issue.These reasons wouldn’t stop you from playing with this idea to learn how it all works. There are a number of very good reasons why you should not build and fly your own ESC. You can pick and choose the output FET for required current level while still getting the same ESC facilities.You could even modify the software to have the ESC record information regarding the flight. This would included modifying the cut-off voltage, brake type, etc. 12F675) you can modify the ESC software at no cost. You may also want to learn how an ESC works. It may provide an additional area of interest for those who like to tinker.For example, if the output FET fails it can be replaced at modest cost. Repair of a DIY ESC may be easier (in Australia repair of ESCs is nearly impossible and expensive).Building your own ESC offers opportunity to get exactly what you want. You may well be able to get the mix of features you want at a reasonable price.Some of the reasons that you may consider using the information here include: None of the other designs offered exactly what I was looking for and in addition there was a certain challenge in programming a 12F675 to do this task.The main one is that being a Flash programmable part it makes a good vehicle for testing ideas and permitting the ESC to be reprogrammed and various ideas tested. None of these projects used the 12F675, and this PIC has a number of interesting features.Online Schematic and Circuit Diagram Tool.Microcontrollers and other Microchip devices Search tool.Find debuggers, programmers, compilers, adapters, socket modules and other accessories for your product.Pic16f877 based projects PIC Microcontroller PDF.Pic16f72 microcontroller based Project List” is locked Pic16f72 microcontroller based Project List.Online Courses to Learn Pic Microcontroller Programming.Advanced View Pic Microcontroller Projects List.Pic10f series microcontroller based Project List of PDF.Pic16f72 microcontroller based Project List of PDF.PIC32 microcontroller based Projects List of PDF.Pic18f452 microcontroller based projects list PDF.Pic18f4550 microcontroller based projects List PDF.Pic16f877 based projects – PIC Microcontroller PDF Downloadable.Proteus based Pic Microcontroller Projects pdf.Pic10f series microcontroller based Project List.Pic18f452 microcontroller based projects.Pic18f4550 microcontroller based projects.Pic16f877a microcontroller based projects list.
