HS10X Oscilloscopes serie are entry level DIY oscilloscopes designed with components easy to source in the market and with the best ratio performance/cost/ease to build.
Power consumption is also one of the lowest in the market (< 0.1A). They can be used only with HScope app for Android.
HScope is in continuous development thanks to the contributions of the supporters, and aim to become one of the best affordable high-tech diagnostic tool.

HS101 Oscilloscope
First of the series, it is a 1 Channel oscilloscope with input range 0-20V, useful for battery testing, voltage logging and oscilloscope applications within this voltage range.
Typical applications
- Battery level logging
- Battery Ignition Off Draw (IOD) data logging (with C650-like amp clamp or a DIY tool)
- Alternator AC ripple level (example here)
- Relative Compression Test (with C650-like amp clamp, example here)
- In-Cylinder Compression Test (with 100 PSIG pressure sensor, example here)
- Fuel Pump Test (with C650-like amp clamp, example here)

HS10X Modifications
You can design your own oscilloscope hardware with several options, using the same HS10X Firmware (which is configurable). After you build your custom hardware you can just set some option in the Firmware (by using HScope) and have your custom oscilloscope working.
Configurations currently available:
– Number of input channels: 1 or 2 channels
– Option for Hardware AC/DC selection
– Input voltage range among these
0-20V (single range)
±5V (single range)
±15V (single range)
±5V and ±15V (dual selection within app)
– Use Bluetooth communication instead of USB
