This resistor box is pretty handy for any hobbyist or electronics work. It can dial-in any resistance value you want allowing you to work with just about any project and adapt it on the fly.
At just about $20 US it’s quite cheap for an electronics tool. The quality seems quite good and I am pretty happy with the purchase￼
If you’re into electronics inventions or repair check this out for a resistance box I think it’s pretty handy and deserves a police on my bench
