 Hi guys, I've got a little circuit here I've been playing with This is basically You can use LM317s. I've got LM388s here I've put two of them in series so the output The output of this one goes to the input of this one and We have a 200 ohm variable resistor on the output of this and 10k variable resistor on the output of on the adjust leg, sorry of all this now this variable resistor controls the voltage and this one controls the unpage so I just Put this second on the supply and as you can see if I just turn that up a second you can see a little I can leave that up. I suppose kind of Seems a lot darker in here, but the the camera's adaptive for it. So oops, sorry about that It's what I've got there is over there a current restriction of 100 mA on that supply We've got 2.8 Bolts there now if I were to adjust this pot here and as long as We're not My touch will do I can turn that up on the pot to the limit of the Of the current But it's actually limited on the board here by this pot So I can turn this up here using this It's here. It's a real dodgy connection if I push it back in again It's because I've had to bend one of the legs on on here But there you go. I can turn that up. I can turn it down and of course That is adjusting When I turn it down on the On there all the way down below even the 1.25 output that you normally get If I continue to turn it up It seems maybe a little bit staggery the way it gets turned up That's drawing 91 84 91 so I back that down again as you can see Also, it starts taking the voltage back down again as well So it's it's basically this thing is on the On the datasheet But if you want to have a look at the circuit There we go I'm gonna put the light back on so watch your eyes So here's the circuit anyway. Should be able to see that I don't know if I'm making any better Yeah, nice and easy does the job and of course you've got the variable on the volume on the voltage as well Which enables you to drop that down Or turn it off because it's currently limited so it literally goes that brightness regardless of how much I turn the voltage up Because we've currently limited it about 200 a About 200 a man resistor variable resistor Great little circuit. Cheers watching guys
