Small-Scale Projects Use Snail-Mail Mail-Scale

stamps.com scale

Stamps.com offers a free USB scale when you sign up for their service. The first versions of this scale did not have a display. In order to find the weight of an object the scale had to be connected to a computer running the stamps.com software. If you happen to have one of these old scales or are able to pick one up cheap, you may be interested in using it outside of the stamps.com service. There are several options on how to do that.

How to weigh a bee hive

Did you know weighing bee hives was even necessary? Of course it is. Monitoring hive weight can tell a beekeeper a lot about the size of the swarm, their harvesting habits, and the yield they are producing.

We had to cover this hack because it’s a fine piece of engineering. [Trearick] designed a bee hive scale that lifts one side of the hive to calculate weight. Using easy to find metal brackets, a hinge, a pulley, and some plywood he built a prying device. The three teeth slip in between the hive and its base and can be separated by squeezing together the plywood handles on the opposite side. This lifts one end of the hive, measuring the force needed to do so using a luggage scale. The readout should be roughly 1/2 the total hive weight. This measurement takes seconds to complete, uses a bulb level on the scale to help ensure consistency, and creates little or no disturbance to our flying friends.

It’s nice to see a Hymenoptera hack that helps in giving bees a healthy place to live, instead of killing wasps.
