Many thanks to SWLing Post contributor, Dan Srebnick, who notes that the Raspberry Pi 4 mini computer was unveiled this morning by the Raspberry Pi Foundation.
This model has a number of upgrades we’ve all been waiting for:
I love the Raspberry Pi and own a number of models that I’ve employed in various projects. For example:
- A FlightAware ADS-B feed
My Raspberry Pi B Pirate is still in service!
- A LiveATC feed of airport KHKY
- A desktop computer for my kids to learn Python and do homework
- A headless remote unit for transferring large files and archiving the full Shortwave Radio Audio Archive
- A Raspberry Pirate FM transmitter
- Two RACHEL-PI systems (English and French) I’m evaluating for use with ETOW
- A stand-alone SDR station
What excites me most about the Raspberry Pi 4 is the improved processor speed and larger allotment of RAM (up to 4 GB). This could make the Pi a more effective stand-alone or portable SDR station. The dual monitor capability could also be a big bonus. And, of course, GigaBit ethernet speeds will help make the Pi a better/faster connected device.
When the Raspberry Pi 3B+ was introduced last year, I hesitated one day and had to wait weeks for the second shipment. Not this time! I purchased two 4GB units (in two different shipments as most suppliers have a maximum of one per customer) and hope to receive them by mid-July.
If you’re interested in pre-ordering the Raspberry Pi 4, check out the Raspberry Pi Foundation website for recommended resellers.
Do you plan to grab a Pi 4? Would you like to share a recent project with us? Please comment!
It would be so helpful if you would post the date that each article was written. As an occasional browser of information, it would be so helpful to know how current the information is.
