This article introduces the design of a high-precision echosounder system that includes the design of a 3D-printed transducer, the design of the controller, as well as the software needed to visualize the data
This post explains the design of an adjustable switching regulator driver for DV-S9 diving flashlight, supporting current up to 1 A and input voltage between 3V and 4.2V, along with low standby current. The driver achieves up to 85% efficiency at maximum current. This design is open source hardware with design documents stored on Github.
This post explain the design of a variable linear driver for the DV-S9 diving flashlight, the driver is capable of handling currents of up to 3 A the input voltage range is between 3V and 4.2V, and has low standby current. The driver achieves an efficiency of between 90% and 70% at maximum current. This design is open source hardware, with the design documents stored on Github.
