What was this video about? Well, my GPIBUSB adapter is for sale! Now, some of you may be visiting my blog for the first time and have no idea what this GPIBUSB thinger is. Fear not, allow me to introduce to project to you!
My GPIBUSB is an open source hardware project that allows the user to connect test and measurement instruments featuring a GPIB (aka HPIB, ieee488) port to a computer's USB port. This allows the user to remotely control their T&M instruments from their computer!
Now, before we go any further, I'm sure some of you would like to see the source files. You can find everything at github.com/Galvant.
|OSHW GPIBUSB Adapter|
The adapter utilizes a PIC18F4520 microcontroller, and a FT232RL to convert from USB->UART. This means that the GPIBUSB presents itself to one's computer as a serial port, giving you the freedom to use a wide variety of operating systems and programming languages with minimal setup.
One could use this adapter for automated tests. For example, you could log power consumption of your device under test by using this adapter to transfer voltage and current measurement from attached DMMs. Another example could include transferring waveform data from one's oscilloscope to your computer to do further analysis.

And of course, the PCB is made in Canada. All assembly is done by myself, also located in Canada.
Now, for those that are interested in ordering one. At the time of writing, I have 8 adapters all assembled and tested, with parts for another 10 on my bench. Cost is $60 CAD plus shipping. If you are from Canada, add 13% for HST. For shipping, options are either FedEx (both ground and express) or Canada Post. An exact number will be given after you contact me and let me know what shipping method you would like.
Payment is through Paypal.
If you are interested, please email me at scasagrande at galvant dot ca.
