9:27 ... " If you do this ... you CAN"T put it outside anymore.... as it is NO longer weather resistant" ( but that's exactly why I want to do this - to make my garden / pathway lights work longer & brighter )

Hi there, You can put the new setup in a weather resistant enclosure and put it outside, that is an option. C :-)

@@childscraig YES ... but I was watching the video for that exact reason .. .then waited until the 10 minute mark to say ... " if you do this - you can't use it for the original purpose anymore." ... so what is the point of making something - if you are REDUCING the options .. it is like saying ... you " could " ... buy a BMW - & use it as a mobile plant stand - if you make a few modifications to it ... like cutting off the roof.

@@childscraig IF I need to buy an additional enclosure ... I am spending MORE than a $1 ... Which is the POINT of the video ... making a $1 item - Better .

There's a lot of line before the join, just leave the join under cover.

Hi Sarah, You would normally take note of this before you disconnect the lights from the old supply, the positive and negative on the old battery would help identify this. If you have already passed this point it's still not a problem, as long as you have fitted your resistor the LEDs will only light when connected the right way round, connecting them the wrong way round should not do any damage as long as the resistor is in place and the voltage you are connecting them to is the right level. Hope this helps, Craig

Hi Peter, This method only changes the power source, it doesn't alter the control at all. Changing the control is a whole other topic and honestly usually more hassle than it's worth given that you can buy static sets very cheaply. Best wishes, C.

Hi Alex, You would need to modify the resistors before you applied that power source, the increased voltage would quickly burn out the LEDs if you don't. When I bench tested the brightness I used a voltage and current regulated power supply to work out the values I needed, you can measure how much current your lights are drawing with a multimeter, from there you can work out which resistor values you would need to drive your string of lights. Just remember, the brighter you run an LED the shorter it's lifespan. Hope this helps.

@@childscraig Wow thank you for your response and help. Liked and subbed. I decided on a 480ohm resistor to achieve 12V power supply (so I can use a Shelly 1 ) and they draw 0.025amps. Cheers!!

Commenting for future project!! Seems that I will need to read this thread

Hi, you are correct that connecting directly to USB without adding a resistor has caused some of your LEDs to fail, the resistors limit the current flowing through the string. If you remove the broken ones and add the resistor the rest should work, they may have a shorter life as they may have been damaged by the unrestricted current, only time will tell. Good luck!

Hi ISO Guy, You can measure the current with a multimeter, it doesn't need to be a bench supply (that's just an easier way). Most multimeters have current measurements, you need to check the instructions on yours (assuming you have one or can borrow one). The meter is used inline so you need to break the circuit and complete it with the meter in the right mode, this should give you the I value for your lights. Most multimeters require you to change where the probes are connected for current measurement, remember to put them back before trying to read voltage otherwise you might damage your meter! I hope this helps, Craig

@@childscraig A friend of mine (an electrician) and he is going to give me his old multimeter. Now thats a bonus. He is going to drop the meter off on Monday on his way to work so my project will have to wait till then. Thanks for the additional tip. Great vid

That sounds like you have the type of light featured in my other video: kzfaq.info/get/bejne/pMhjf9l23rWWepc.html

Hi Limnana, 80mA is the power consumption of the LEDs before we modify them, you can measure this using a multimeter inline with the circuit before you take the unit apart. In my case I have a bench power supply which I can use to show me the voltage and current however you can do the same measurement with a multimeter in A/mA mode. I hope this helps, C.

Craig Childs Thank you so much ☺️☺️
