9 Volt Power Supply For LCR-T4 Tester. No More 9 Volt Battery ( Installation )

Super cool!
I use the same 12v set up with Anderson power poles for everything.
What I did which is more expensive but simpler was but rechargeable lithium ion 9v batteries.
At some point in going to build this circuit anyways.
Looks like a fun project.
Thank you for sharing.

Wow

NO FRIGGIN WAY, I just bought one of those and received it yesterday. I ordered it to measure some inductors I made for a one tube regenerative receiver Iam building, so far it's very inaccurate for inductance measures.
I have a coil with a known value of 300mh I put the coil leads on terminals 1 and 2 and it shows me a measurement of 0.020mh WTF??? Maybe it works ok with transistors, but inductance coils, forget it. I'll stick to a piece of paper and a ✏️.🤣👍

Purty smart!

I have the same taster. I installed a flat Li Ion cell from a phone that died, it's a 2.4Ah cell. Combined with a boost converter and an ON-OFF switch, it can take months if not years before needing to charge that battery (depending on usage)

I just bought a usb rechargeable 9 volt block for this, solved the problem.

I have a couple of these meters. And dozens other meters in multiple locations.
Simple fix - take out the battery when done using.

Excellent idea. I'm going to convert my component tester the same way!

I use TP4056 charger, lipo battery and voltage booster for portable. If you want low noise, you can make the booster output 12V and add a 7809.

Does it have the regulator on the device already? Maybe you can connect 12V to the device directly if the onboard regulator can handle it. You could even keep the battery option to keep it portable.

Great video. ✌✌

I just read one of your post about keeping humble Happy holidays

Very nice! The 78xx series voltage regulators are great! You can put a 1Nxxxx rectifier between the middle lead to ground and increase the output by .7 volts. The cathode goes to ground. Want to increase the voltage more? Then put one or more in series. Each will add .7 volts to the output. Want even more? Then put a zener diode between the center connector and ground. But the cathode goes to the 78xx I.C. That will boost your output voltage to the zener, plus the value of the 78xx voltage regulator. Just keep in mind that your input voltage must be high enough to support the circuit. You can’t get something for nothing.😊
