    longevity and sealant

    I've got a few teensies soldered together and a lot of sensors attached to them. How long can I expect this to last before things start breaking down if I did a good job soldering and the device...

    soldering teensy wire to a chunk of copper

    I'm hoping to use some CNC'd copper (or aluminum, but I assume that will be even harder) as the conductor for a proximity sensor that is being read by touchRead on a teensy 3.2. How do you suggest I...
  3. epic teensy translational neuroscience/motor learning project

    Hey Everyone, with much help from this forum and much trial and error, I am finally at the last leg of prototyping a super cool device that I've made using 6 teensies and 17 sensors in concert with...

    using multimeter with teensy

    I have a teensy 3.2 plugged into a laptop via usb hub, and the teensy 3.2 has a sensor attached. The same teensy 3.2 is also sending analog input to a teensy 4.1 plugged into the same laptop via a...

    shorting pins between teensies

    I'm reading a proximity sensor on a Teensy 3.2 and having that Teensy 3.2 output a scaled value through its analog output to an analog input on a Teensy 4.1. I have both teensies plugged into the...

    Ok. If I do this with 5 teensy 3.2 boards inputting to the analog port on the teensy 4.1, will the circuit pass the overall current rating of the teensy 4.1? or no because all the teensy 3.2s are in...
  8. fastest way to communicate between two teensies

    I have a teensy 3.2 and a teensy 4.1 plugged into the same laptop. Both teensies are connected to the same ground (the laptop via USB), and there is a jumper cable from the teensy 3.2 DAC/A14 pin to...

    thunderbolt with 5 teensies

    I've been doing some reading about how to connect a bunch of teensies together, but the forum posts I've found have either been for different devices or very outdated based on the use of old USB...

    timeout for serial.println

    Hey All. I'm using the Teensy 4.1 to sample a set of sensors for graduate work. Currently I have it sample at 4kHz (once every 250us) and print the sensor readings. However, sometimes there is some...

    Hi, thanks for your reply. So if I use 6kOhm which then connects to the 10kOhm that goes to ground, that is fine? Does this prevent more than 3.1V from leaving the EEG Click at all, or does it cause...
  14. voltage splitter to avoid 5V input to teensy 4.1

    Hi,

    I am using a bunch of different sensors (FSRs, photodiodes) with the Teensy 4.1. I am adding this EEG shield to the same teensy: https://www.mikroe.com/eeg-click

    Unfortunately, the EEG...

    serial bus bandwidth

    I am working on a project where I would like to stream large amounts of neural data to a computer via bluetooth, simultaneously with rapidly streaming Teensy 4.1 data via usb.

  17. many teensies for rapid parallel proximity sensing.. but which teensies?

    Hi Everyone.

    I'm working on a project that requires input from 5 cherry mx switches, 5 force sensors, 5 capacitive touch sensors, a photodiode and an EEG shield. I'm using a teensy 4.1 to poll all...
