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.
