Adding a multitimbral MIDI SoundChip to Arduino Part two of a multi-part blog post on building a MIDI synth instrument. The basic idea is to use 3 Arduino's to make a visual / sound instrument. Arduino 1) Send control data. Arduino 2) Generate wav audio from MIDI input. Arduino 3) FFT EQ visualization. LET'S BEGIN ! Solder on Stackable headers. Careful to try get the headers aligned. ProTip is to put your stacking headers to the table & set an old shield underneath with pins facing up (into the receptacle end of the headers) to line them up for easy soldering. So a shield underneath this one in the photo below. I just went for it & tried to hold it still,...
Control MIDI the old fashioned way. With knobs. Part one of a multi-part blog post on building a MIDI synth instrument. The basic idea is to use 3 Arduino's to make a visual / sound instrument. Arduino 1) Send control data. Arduino 2) Generate wav audio from MIDI input. Arduino 3) FFT EQ visualization. Yes, it would be simper to do this with an Arduino Micro (or RPi3) + a teensy for similar functionality. But not as much fun. LET'S BEGIN ! Soldered the MIDI jacks first. Make sure to solder them flush to the board. Since they need to withstand plugging cables in & out, good to get them perfect. OR make a case which takes some of the brunt...
Update September 25: For the time being, a Canada Post strike has been averted. At this point, if a strike were to occur, the CUPW has to give a 72 hour notice. The union has stated they will not give notice on September 26. We will continue monitoring the situation, but for now, it appears that Canada Post remains a good shipping option. Original Posting from September 12, modified September 25: In what seems to be a bi-annual tradition, Canada Post workers may go on strike. We sincerely hope that the CUPW and Canada Post can come to an agreement. Canada Post is the most economical carrier we use, and with our high volume we pass along great savings on shipping costs to our...
A new regular Blog series.Featuring quick overviews of the various platforms Elmwood offers.Intro to Wearable/Sewable Electronics aka 'e-textiles' : Adafruit. Common Elements: Conductive thread instead of copper wire or circuit board traces. Sewing Fun ! Different Product lines: [Adafruit's evolving wearable ecosystem explained with Starbucks Sizes.] CircuitPythonExpress aka 'CPX' ( Venti ) Flora ( Grande ) Gemma m0 ( short ) Trinket m0 ( tiny ! ) m0 uses Circuit Python Language. Older models, aka 'counting all the chickens' : There were non-CircuitPython ArduinoIDE 'C' based versions of most boards in the past. Flora is still ArduinoIDE based. Adafruit has slowly moved it's product line to be programmable with CircuitPython (a smaller subset of the Python language targeted to small microcontrollers). Also...
