Programmable Dummy Load build

in builds by DP | 5 comments

Schazamp built the Programmable Dummy Load free PCB. It’s a new development project which allows you to set the load current via USB, or LCD/encoder combo.

If you build a free PCB we’ll send you another one! Blog about it, post a picture on Flicker, whatever – we’ll send you a coupon code for the free PCB drawer.

    I’m interested to build a electronic load and get a free electronic load PCB, what should I do ?

    this is nice. I remember I also designed something like this constant current sink 3 years ago. Then I implemented “constant resistance mode” implemented in firmware (the firmware needs to read the ADC continuously). Being unhappy with the previous method, I then improved it again by implementing the “constant resistance mode” using an additional op-amp.

    i have some short of load for driving led .so i need some dummy load which can waste power upto 60w and with less heating effect. can u suggest something
