NullPerator Tiny Tracker

This is a tiny tiny tracker that I made for fun years ago, but people seem to be interested in it, so I’m planning to bring it into production.

Demo of the prototype

It runs a modified version of PicoTracker firmware right now. It has 8 tracks for synth & samples.

The hardware & software will be open-sourced so that people can put their own software in it.

Detailed Spec:

  • ESP32-S3 High-performance SOC
  • 32MB of Flash
  • 8MB of PSRAM
  • 1.54 inch 240x240 IPS display
  • Bluetooth & WiFi wireless capabilities
  • Hi-Fi quality audio codec
  • Stereo Audio Output
  • Stereo Audio Input (Alternative mode for the audio output jack)
  • TRS MIDI in & out (Type A for output, Type A&B auto detect for input)
  • Onboard speaker
  • Onboard microphone
  • Headphone Mic support
  • 6-axis gyro & accelerometer
  • High-speed micro SD card support
  • 720mAh battery (estimated ~5+ hr of usage)
  • 6 GPIO, UART, I2C exported via 20P FPC for development purposes
  • 4P JST-SH I2C expansion port

If you are interested, I’m planning to make a small batch of it (around 50 units) and I’m taking pre-orders for them: NullPerator – 203 Systems

I would love to know what do you think about it.

This is really cool! Genuine question, how does it feel to hold? I’ve got tiny hands and I’d still worry about cramping.

Congrats on the hard work! This looks super cool.

That ants comment was very internet-y.

I was like “this is cool but I don’t need it” and then I saw the baby hand

Feels pretty comfortable to be honest. It’s very light, so no force is needed to hold it. I know it sounds unbelieveable but it’s pretty usable.

Very good work. Is there a manual?

Lovely device, is that a babies hand? A thumb of mine would cover all buttons and half of the screen :smiley: but it looks sturdy, is it made out of aluminum? I probably could hold all 50 preorders in 1 hand :smiley:

Or a keychain edition?

No manual yet, but feature wise it’s same as PicoTracker V2 at the moment.

Trackers are awesome ! Trackers are small ! Trackers give me headaches after 20 minutes due to eyes fatigue ! Trackers are for young eyes ! Trackers are unfortunately, not for me anymore…

Good luck on your project !

NullPerator Pre Production version demo

Just got the pre-production version ready. Still need to polish some details but it’s looking really good. Got a short clip from my friend testing it before getting it here in the states.

Looks interesting. Would like it better if it has some sort of enclosure around the front components and buttons my stubby fingers could press.

This is mostly designed this way so it can be as small as possible. Otherwise, bigger options like PicoTracker ADV or M8 tracker are way more practical.

I was thinking of my M8 when I looked at it.

They are designed to be way more practical than this haha. I originally designed this for myself but decided to produce some more for people interested.

If I designed it to be more practical, then it would lose some charm. It’s mostly a very tiny version of PicoTracker, so there are already more practical versions.
