"Propeller Clock" Mechanically Scanned LED Clock Seven light emitting diodes spin‚ giving the illusion of numbers in the air An Overview: Top View Side View How this clock works: A motor spins the "propeller"‚ and a small microprocessor keeps track of time and changes the pattern on seven LEDs with exact timing to simulate a 7 by 30 array of LEDs. It is an illusion‚ but it works nicely. To build this clock‚ few things are needed‚ including: 1. Skill with motors and mechanical

What I do while waiting is make a small kind of bowl for my marijuana out of the "optional extra" aluminum foil so that it is easier to collect/check my weed after it has been through the oven. Before: Put the weed in the oven‚ and set the timer for 15 minutes‚ that should be enough. You can tell if you pinch your nugs and they fall apart into dust that you are perfect. Now keep your weed to the side for one moment. After: Steps: (Part 2: baking your firecrackers) Technically this part

its lighter weight of 7 lbs‚ which makes it slightly more portable than the Virtuoso. The Baratza Virtuoso makes the front-mounted pulse button feature even more useful and efficient with the addition of its 60-second timer - something that the Encore does not have. The timer and pulse button combination lets you do a more precise grind‚ and enables you to repeat that quality with every use. This is especially important when it comes to grinding into an espresso basket‚ which requires very fine

An air track is an apparatus that simulates the effects of frictionless motion. A known mass is attached to an air-cart on an air-track apparatus. Attached by string‚ the air-cart is pulled by the known mass when hung over a pulley. A spark timer will mark the motion at a frequency of 10 Hz (10 dots/s) on a strip of paper called ticker tape. The air-track will supply air through the apparatus to simulate a frictionless environment‚ enabling the system of masses to move without an applied force or
