cheap regulator test AMS1117-5 are they any good??

-
today in this video i'm testing a low dropout voltage regulator bought from e-bay.  the AMS1117-5 is a fixed voltage low dropout regulator and according to the datasheet can provide 5 volts output at 1amp max .the operating voltage is up to 15volts max. watch the video and please comment: is it worth buying or not?



schematics of the circuit under test.

low battery indicator circuit

this is a very usefull circuit if you're building projects powered by batteries.this simple circuit informs you when the battery needs to be recharged by turning on a led.the threshold is set to the desired voltage by a multiturn potentiometer. the only thing you should have in mind is that it doesnt work with red led's,at least with the ones i tryied. i think it has something to do with the very low voltage that red led's need to lit.didnt have the time to experiment further.besides that,the circuit works perfect. components needed: R1= 1k (2,2k if you use smd led) R2= 2.2K U2= TL431 adjustable shunt regulator(can be found very easy in power supplies) PR1=10K potentiometer (for higher precision use multiturn)  LED1= led (not red-didnt work with me) here is a video building it.

ADJUSTABLE TEMPERATURE SOLDERING STATION

this is the first test video i uploaded to my new youtube channel so please forgive the poor quality of the video. in the next videos im making i will provide a more detailed presentation and HD video of this project. if you don't wanna miss it please subscribe . ------------------------------------------------------------------------------------------------------------ this is an adjustable temperature soldering station using arduino uno or pro mini to sense the temperature and control the soldering iron. this circuit-project is used many months now in my workshop.i built 4 of them and gave one as a gift to a friend and all of them work flawlessly. the solder iron used is a cheap hakko clone which uses a type k thermocouple for temperature sensing. notice that i didnt use the L7809 regulator shown in the schematics because it was geting too warm.instead i used a buck converter for the 9 volt output for the lm358 and then a L7805 regulator  to power the arduino.you can a
