Why Not using a Attiny 13 to make it easyer. I used an old Monitor ccfl whith inverter that has a pwm input Pin, An on /of Pin, and powepins. I used only one 555 timer to trigger it. no mosfet driver ic is needet. And also no buck-boost converter becourse the ccfl inverter works on full Power at 9-14v input. I used a lead acid 1. 3Ah Batterie becourse its heavy and works as a solid Base for the Lamp. It works for 2, 5 h on full Power.

Hi, Great Scott. these things interest me alot but i'm not sure what to do or where to start, i'm not fortunate to go to a university to learn. But I still would like to learn about Electronics. Would you recommend any books for starters? Or any books in general about the work you do?

THis is a really good video. I like that you always share the schematics! The only thing is that I don't really understand why is needed the TC4420? Cant we just connect the TLC555 output to the Mosfet? If someone know, I will love to hear the explanation.
Thanks.

Hey scott what temp do you use when you solder? i need to desolder some components from a network switch that i am trying to fix and last time i tried to solder it is either the temp is not hot enough or there are other problems. Can you give me any advice?

Hi Scot
How can I make a circuit which charges a Sony NP-F battery when a power source is connected and only drive by the power supply?
I am currently waiting for a voltage booster from China, which takes the voltage from 7. 4(8. 2) volt to 12 volt

HiCan the NE555x2 change to NE556(Maybe ok?
AndI want to know How much voltage range Output from Ne555?
In my 555 circuit, the voltage range it is about 0. 6v, is that correct?
Sorry my English is not goodI live in Asia, Taiwan

You said that the ledstrips need 3 amps. But that means that you can't use the warm and coldwhite ledstrips at 100% at once because the buck boost converter can only take 5amps. Am i right or did i miss something?

Hi!
Great work!
in the scheme it seems that you join the pin 6 and the 7 of the tc4420 but in the protoboard on the side of the welds I do not think they are united. I'm wrong?

The picture quality of the diagram given by you is not good, because of this I am not able to build this project. Well the projects you made are very useful
