What is Pocket Science Lab

All in One Device. PSLab is a small USB powered hardware extension for your Android phone or PC that lets you measure all kinds of things. PSLab comes with a built-in Oscilloscope, Multimeter, Wave Generator, Logic Analyzer, Power Source, and we are constantly adding more digital instruments. PSLab is many devices in one. Simply connect two wires to the relevant pins and start measuring. You can use our Open Source Android or desktop apps to view and collect the data. You can also plug in hundreds of compatible I2C standard sensors to the PSLab pin slots. It works without the need for programming. So, what experiments you do is just limited to your imagination! PSLab is developed by FOSSASIA and OpnTec in collaboration with a global community of Open Source developers.

Other information

  • 4MHz, 4-channel Logic analyzer with 15 nS resolution.Voltage and Current Sources
  • SPI, I2C, UART outputs
  • Graphical Interfaces for Oscilloscope, Logic Analyser, streaming data, wireless acquisition and several experiments developed that use a common framework which drastically reduces code required to incorporate control and plotting widgets.
  • PSLab also has space for an ESP-12 module for WiFi access with access point/ station mode.

How can it be connected to the phone or PC

Pocket Science Lab is directly powered through the USB connection. It doesn’t need any other external power source. All you need to do is to attach it to the phone via a USB OTG cable if you are using the mobile app or directly to your laptop’s USB port if you are using the desktop app.

What sensors are available

PSLab has digital pins to plug in sensors and extend the functionality even further. The device supports any sensor using the long-established I2C standard. Hundreds of compatible sensors are available on the market. I2C sensors are used widely in consumer and industry devices and for example with Arduino boards. A list of recommended components and sensors is available here.

How to use ESP WiFi and Bluetooth

PSLab has slots for ESP and Bluetooth chips. The functionalities are already implemented in the firmware. Solder the chips to the dedicated slots. For the WiFi functionality also don’t forget to install the relevant packages on the ESP WiFi chip and you are ready to go. Devices can be powered through an external battery when they are accessed through Bluetooth or WiFI. 

Who develops it and how to help

PSLab is developed by FOSSASIA in Singapore and OpnTec in Germany together with a global community. You can join and contribute to the development by collaborating on the Android appdesktop appsfirmware and hardware on GitHub. Please join development if you are developer or learn and promote Open Science and PSLab.
