I have been using blast media for years as tumbling grit in my rock polisher. It works perfect for the first stage of the rock polishing process. And it is always more economical than anything labeled "lapidary". The only difference I have found is that Aluminum Oxide requires a little more water when using it in a tumbler.
As blast media goes, this is as good as any other that I have purchased. It is consistent in grain size and composition. This media will work perfectly for smaller sand blasting booths and will recycle through the system for multiple uses.
At nearly half the cost at my nearest retail store, this 10 pound bucket is a big savings on a consumable item, and I recommend trying it out. It works great as a table piece in our home. Assembly was straightforward.
Originally I had a mini-internal fan on my Raspberry Pi 5 computer directly over its CPU, with the Pi being enclosed within a metal case and equipped with an NVMe hard drive. After a week the original internal fan started making a lot of noise. Arghhh.
So I opted for this much larger, external fan instead. I placed this external fan beneath the Raspberry Pi 5, so its perforated metal closure rested on it, directing the airflow up from the bottom and across the Pi. Note: to best accommodate this, I had to place a support below this internal fan so it would draw in maximum air at high speed, else it would suffocate.
Results: the Raspberry Pi 5's CPU cooled down from 70C to 49C at maximum workload. And every other sensor on the board cooled between 18-21C as well. One other note: I would not recommend using the fan at an angle as you can begin to hear some noise, and after a long time, I would assume bearings may pre-maturely wear out. It works great as a table piece in our home. Very happy with the purchase overall.
Easy to assemble. Took less than 30 minutes and I'm in my 60s. Very nice. It works great as a table piece in our home.
