A couple weeks ago I received a really nice Tenma Soldering iron from a friend.  The other night while I was looking through the Banggood Electronics I came across a very inexpensive solder iron that reminded me of the handpiece of my new iron. The one my friend sent was a bench station and this one was a direct plug in with a small dial on the handle. It also came with 6 tips so I decided to take a chance and ordered one of them.   They were on sale so my total cost including shippin ...
In the good old days (I remember them well) we didn't use any of the newfangled highfalutin semi conductors to regulate current. When necessary for short term precision current regulation we used a mechanical current regulator like this one:     It is built a little like a high quality buzzer and you can see the precision adjustments for both the tension on the armature and for the position of the contact points.  As the current in the coil increases the contact is opened for a ...
Thanks to a gift from a good friend I have for the first time in my 60 year walk with electronics a temperature controlled solder station Up until now it has always been one or two unregulated power levels As is the case with most of the things we are accustomed to we are hesitant to try something new Here is a link to the Tenma  21-10115 solder station from Newark Electronics which I recieved   http://www.newark.com/tenma/21-10115/soldering-station-esd-safe-60w/dp/56T2208   He ...
There are two stations at my main work bench. The first station is for bread boarding and testing components, circuits and prototypes. The bulk of my test equipment is arranged at this end of the bench. The other end of the bench is set up for soldering and desoldering as well as minor mechanical operations. After setting up this arrangement I found myself frequently jumping back and forth from one end to the other to test this or that component as I removed them from salvage circuit boards. Fin ...
