Open Source Hardware - OSHW

OSHW

OSHW Draft Definition 0.3 is based on the Open Source Definition for Open Source Software and draft OSHW definition 0.2, further incorporating ideas from the TAPR Open Hardware License. 

Open Source Hardware (OSHW) is a term for tangible artifacts - machines, devices, or other physical things - whose design has been released to the public in such a way that anyone can make, modify, distribute, and use those things. 

4N35 Optocoupler

4N35 Optocoupler

The set 4N35, 4N36, 4N37 are popular and versatile optocouplers for isolation of circuit blocks. The most important feature is the Isolation test voltage 5000 VRMS that means 5KV. But PCB Design is very important to get this isolation for your products too. 

LM317 - Adjustable 3-terminal Regulator

LM317 - Adjustable 3-terminal Regulator

The LM117 series of adjustable 3-terminal positive voltage regulators is capable of supplying in excess of 1.5A over a 1.2V to 37V output range. 

LM317 3-Terminal Adjustable Regulator

Because the regulator is and detects only the input-to-output differential voltage, supplies of several hundred volts can be regulated as long as the maximum input-to-output differential is not exceeded. That is, avoid short-circuiting the output.
