New DSP|Power boards arrived and i discovered i could actually make the external 3.3V supply in a more proper way, without any tricks with LEDs supplying voltage to the VBAT. I'm using the TPS63001 buck-boost DC-DC converter to keep the 3.3V...

Make sure there is indeed a solid connection between the MCU's pin and the 100R resistor. 1.57V measured with the multimeter is an averaged value, since it cannot measure such high frequencies. Maybe the solder ball is flaky for that pin and the...

None, it's just a wrapper for consistency (other reverbs use "time").

Hey everyone, I’m pretty new to doing Teensy projects, but getting really stuck in. I wasn’t super impressed with the stock reverb (designed for a different era with different hardware, not the 600 MHz DSP we have now!) so figuring this would be...

While i'm waiting for the new PCBs, i tried to make some music and a short introduction video for the project. Again, the TGX4 is the main source for all the guitar sounds, plus a few external pedals

More power related adventures: the idea from the post above is basically scrapped. Everything works very nice until such a power bank system gets near an electromagnetic guitar pickup, especially a single coil one as used in this guitar. It's...

Power section and related adventures: for the power section i went with the IP5328 power bank controller chip, mainly because it's a compact one chip solution to get multiple fast charging protocols and a stable 5V output. Plus the IP5328 chip...

The drone synth and the preliminary version of the looper in action. Amp/cabinet sim and effects (delay, reverb) are also Teensy based (TGX4).

Visually it's pretty much finished. The only hardware part requiring more work is the battery. The power bank will be replaced with two 21700 cells with charger/5V boost board based on IP5238 with I2C and few other signals exposed. Teensy will be...

I'm still waiting for new pickup covers, once installed i plan to make a proper photo session. Guitars play a quite important role in the CP2077 game, you can even go home and play some riffs. However, this one is not a reproduction of any...

this project has been in the works for over a year now. The guitar is based on an DIY kit (Harley Benton JA) which is heavily modded and upgraded, mainly with electronics. Hardware design is split in three main parts: 1. Pickguard, a large PCB...

Hey there! The 3D waterfall display of a wavetable on the Jeannie 2's touchscreen looks pretty cool compared to the smaller Jeannie 😎 3D wavetable display on the Jeannie 2 Little Jeannie
