Breville Grinder Impeller Upgrade

One of the parts that can fail/wear relatively quickly in breville grinders is the impeller, and getting a hold of one via breville support can be tough.

One alternative is to 3d print! If you have one, and it is precise enough.

Shapeways is a great service that does very high quality 3d prints, and mails it to your house, and you can get a replacement breville grinder impeller here.

MD380 best DMR antenna

The antennas that came with the MD380 aren’t very good, and are really just a dummy load, and are cheap plastic.

My MD380 came with two antennas. A shorter one, and a longer one. Both worked okay for receiving, but left a little to be desired in quality. When I swapped between the two, I noticed metal shavings being left behind on the radio’s connector, and then they wouldn’t screw in as easily.

I found the Smiley Antenna Slim Line 440MHZ  antenna via reddit, and purchased it. It’s tuned specifically to 440MHz which is at most 5mhz off from the DMR repeaters output frequency in my area.

Much better metal collar of the smiley antenna.
