Let’s Rock n Roll with This Fantastic eDrum!

Do you have the passion on music industry, especially with the drum? Honestly, most of the neighbors can’t really stand with all the loud drumming sound all day long, hence you’re probably ended up by getting endless complaints from the neighborhood! If you’re frustrated and want to find the solution for the above matter, then this eDrum might be the perfect match for you! For your information, it’s not a hard task to build an electronic Trigger to MIDI converter module that based on PIC Microcontroller. Basically, the eDrum design is mainly based on PIC16F877 RISC microcontroller from Microchip running at 20MHz, by two line LCD with backlight on it and some operational amplifiers. eDrum will has these following features: 22 analog inputs, 2 digital inputs, 22 input gain potentiometers, 4 control buttons, one MIDI out and one serial RS-232 out. For your information, the main goal of this design is to use the cheap and easy to find electronic components, but it must be maintaining the optimal results. By using this eDrum, you’re now can slow down the volume… Continue reading

Electronic Drum Controller Will be Your Good Music Companion

If you a die hard fan of Drums, I bet you must be excited about this unique and DIY eDrum too. The required components for this project: A PIC16F877 RISC microcontroller Two line (16×2) LCD with backlight Some amplifiers Twenty-two analog inputs Two digital inputs Twenty-two input gain potentiometers Four control buttons One MIDI out One serial RS-232 out You need to remember the main goal for this project is to find and use the cheapest components, but can still be maintain results at the professional standard. By using the PIC microcontroller, the whole design becomes easier to expand and it’s also assembly language friendly as well. Below is the list of eDrum special features: 24 unique velocity sensitive trigger inputs One Hi-Hat stereo input One Snare Dual-Piezo input Six Cymbal inputs with the choke Four Mono Piezo inputs Two modes HiHat pedal operation One MIDI output Four control buttons The RS232 serial port Assorted memory for snapshots Various controllable parameters Since this project is mainly about the Trigger to MIDI conversion matter, therefore the eDrum will not offer any… Continue reading
