3D Printed Indexing Gears (MVMT 68): 7 Steps (with Pictures)
Saved by uncleflo on December 20th, 2019.
This mechanism uses rotary motion to move a gear quickly and precisely into a fixed position. Using skateboard bearings, you can snap these parts together and use the action for all kinds of useful (or useless) machines. Using gears that have teeth and smooth gaps, you can make a gear spin and stop at just about any angle you want. This is similar to a geneva gear, but it's much simpler to 3D model and (I think) a bit easier to understand. This is the first in a series of 3D printed mechanisms modeled in Fusion 360 using skateboard bearings and 3D printed parts. The idea is that you'll be able to use the mechanisms to make all kinds of projects that use mechanical assemblies like robots or any other machine you might want to make.

Sevenoak SK-EBH60 Mechanical Panoramic Head 60 Minutes 360° Panning Rotating Mechanical Time Lapse Stabilizer for GoPro Action Camera SmartPhones DSLR Cameras(Black)
Saved by uncleflo on November 28th, 2018.
SK-EBH60 is a portable turntable that provides an ideal solution for creating time lapse videos or panoramic stills with GoPro/action cameras, smart phone and cameras up to 2KG. It includes a 1/4-20 cameras screw on the top and a 3/8 to 1/4-20 socket at the bottom for a tripod, and it can also be used directly on a tabletop or other flat surface. Based on a simple timer mechanism that needs no batteries, the SK-EBH60 is capable of panning 360°counterclockwise in 60 minutes. For clockwise panning you can hang the unit upside down, although this is only recommended for GoPro/action camera, smart phone or cameras weighing less than 1LB. The minimal interface allows the tripod head to be set and used quickly, as well ampletes a 360° cycle in 60-minutes. Stack two heads for double the speed.
Durable Construction, Precision Mechanism; Compact and portable, easy to use.
Features a standard 1/4" mounting screw for digital cameras & DSLR's. Includes GoPro Tripod Adapter for GoPro HERO, HERO2, HERO3, HERO4, etc and Smartphones Adapter for iPhone 4, 4S, 5, 5S, 6, 6-Plus, 6S, 6S-Plus and Android Phoness allowing for a second tripod head to be mounted on top to double the speed of the cycle - a complete revolution in 30 minutes.To double the panning speed, you can stack two units together.

Seiko Watches > Thermic
Saved by uncleflo on May 31st, 2018.
The world’s first watch equipped with a mechanism for thermal power generation. The thermal power elements generate electricity from the temperature difference between the body and atmosphere and store it as energy in a secondary battery. A full charge keeps the watch running for about 10 months. The Thermic generates electric power via the Seebeck effect, a phenomenon produced when heat transfers from the back of the case to the case surface. To improve energy efficiency further, a power-saving mechanism stops the second hand whenever the watch is removed from the wrist.

Locking for Concurrency in MySQL
Saved by uncleflo on May 9th, 2018.
The first and most important point is that the primary use of locking is to solve concurrency problems. If scripts are being implemented that write to the database but aren't multistep operations susceptible to the problems described in the last section, locks aren't needed. Simple scripts that insert one row, delete one row, or update one row, and that don't use results of a previous SELECT or data entered by the user as input, don't require a lock.

How to find out who is locking a table in MySQL
Saved by uncleflo on April 18th, 2018.
MySQL is adding more tools to monitor its internals with every new release, but one thing it still lacks is a way to find out who is locking what, and therefore which transactions block which other ones. This is such a vital feature that I’m considering writing my own patch to the source! Still, it is possible, to a limited extent, to find out who’s locking resources. In this article I’ll explain how you can do that. This article is the second in a series on how to use the innotop MySQL and InnoDB monitor.

Secure hash and salt for PHP passwords
Saved by uncleflo on October 17th, 2016.
It is currently said that MD5 is partially unsafe. Taking this into consideration, I'd like to know which mechanism to use for password protection. This question, Is “double hashing” a password less secure than just hashing it once? suggests that hashing multiple times may be a good idea, whereas How to implement password protection for individual files? suggests using salt.I'm using PHP. I want a safe and fast password encryption system. Hashing a password a million times may be safer, but also slower. How to achieve a good balance between speed and safety? Also, I'd prefer the result to have a constant number of characters.

Muammer Yildiz: Over-unity Homopolar Electrical Generator -- Patent, articles
Saved by uncleflo on February 22nd, 2015.
This is a portable system that generates electrical power via an accumulator that provides the initial motion for the system. Two batteries are used in this system and the system is kept working via the initial motion provided by these batteries. There is no need for another transformer. This device works using its own mechanism and there is no need for additional devices. In this way, a continuous electrical power generation is possible. This device can work without connecting it to a network so it is possible to use it at places where electricity does not exist. Moreover, when connected to the entry of a building, the need for a network is avoided. This system generates electrical power independent of a network.

A modern JavaScript router in 100 lines
Saved by uncleflo on February 22nd, 2015.
Nowadays the popular single page applications are everywhere. Having such application means that you need a solid routing mechanism. Frameworks like Emberjs are truly build on top of a Router class. I'm still not sure that this is a concept which I like, but I'm absolutely sure that AbsurdJS should have a build-in Router. And, as with everything in this little library, it should be small, simple class. Let's see how such a module may look like.

samyk's evercookie at master - GitHub
Saved by uncleflo on January 20th, 2015.
Evercookie is a Javascript API that produces extremely persistent cookies in a browser. Its goal is to identify a client even after they've removed standard cookies, Flash cookies (Local Shared Objects or LSOs), and others. This is accomplished by storing the cookie data as many browser storage mechanisms as possible. If cookie data is removed from any of the storage mechanisms, evercookie aggressively re-creates it in each mechanism as long as one is still intact.
