DIY video of making the universal 1 2 3 blocks. A2 tool steel setup blocks designed by Robin Renzetti. These blocks are truly universal and can be connected in nearly any configuration. We take a look at some of the machining operations to make them. Its a must have tool in every machine shop.
Given two batteries, it chooses the one to connect to the load based on the voltage measured at their poles. It can also be used to switch DC power supplies. The circuit we are proposing is an automatic battery switch made with power MOSFETs with very low RdsON, which are specifically for SMD.
The desperate search continues for survivors of a recent tsunami which struck parts of western Indonesia, as the country marks the 14-year anniversary of its 2004 Sumatra tragedy -- one of the most devastating ever recorded.
In today's video I will be showing you how I created a folding desk for my son's bedroom a couple of years ago. I decided to design a desk that had NO HINGES WHATSOEVER - and this is how I did it! Materials for the build is MDF - 25mm and about 8mm metal pin.
