Two DIY micro-controller based USB connected electronic units which along with the Texas Instruments Analog System Lab Starter kit and a laptop permit you to conduct analog experiments anywhere.
It would be wonderful if senior students and laboratory supervisors built these units so that they could be used in their laboratories by freshers.
Analog System Lab Starter Kit ASLKv2010 http://www.uniti.in/teaching-material/analog-system-lab-starter-kit
Step 1: Aj-SigGen-PS
This unit is designed to compliment the Aj-Simple-Scope and serve as a teaching aid for budding engineers, electronic enthusiasts and hobbyists.
This USB connected unit implements a microcontroller based DDS Signal Generator providing Sin and Triangular waveforms with adjustable magnitude and offset up to 50 kHz. TTL and 1 V square waves are simultaneously provided. Additionally ± 12V and a variable +2 to 7V output with a total capacity of 1W is provided to power external circuits under test.
