RP2040 Powers A MIDI-Controlled Soundboard

When you’re livestreaming, it can be tempting to fire off all kinds of wacky sound effects like you’re a morning radio DJ back in the heady days of 1995. If that’s who you want to…

Less welcome news from Carrie at @alpenglow, sadly: the business is shutting up shop, with a stock clearance sale now on.

Hopefully not the end of Carrie's excellent projects, though - I've loved seeing those over the years.

Rather late #Hackster round-up to start this week, 'cos my eldest wanted the desktop to play with some friends so I took the opportunity get some stuff done offline.

First up, a device from @bikerglen that turns any MIDI control surface into a fast-boot soundbox for live or streaming shows.

PSA: directfile.irs.gov is dead. Not even a "we're closed" message with alternatives. Instead of going back to Turbotax or H&R Block, use freetaxusa.com. Ridiculous name, legitimate business. Federal filing is free. State is $16. Happily using it for the last 5 years. No referral code, just spreading the word.

My latest project uses an RP2040, a MIDI controller, and an I2S DAC to play back sound effects during live streams! There's even a speaker version for use in person. Full details here: https://bikerglen.com/blog/rp2040-midi-soundboard-player-for-live-streaming/

Right, plans to finish the day with a bit of hardware testing have been derailed 'cos a cable that I *swear* was on my desk yesterday is now... not. So, #Hackster round-up time.

First up, a 3D-printed traffic light model that goes further than most - by having each "lamp" be a full-color bitmap display.

Ever wonder how your 3D render stacks up against reality? I think I got pretty close. Build your own colorful Neopixel spotlight using 3D printing and an Adafruit Sparkle Motion Mini and Neopixel Jewel. https://bikerglen.com/blog/my-first-neopixel-party-light/
