Digital Overlay Learning System
Overview
Â
To assemble and examine experiment is laborious. OLS Series will condition the students to visualize the function of experiment circuit. Electronic theory will be taught straightly out of book accordingly.
The main objective of this trainer is to teach the student of electronic circuits rather than focusing on the assembly of the components.
Features
Â
- The OLS-2000 overlay learning system allows the student to assemble even the most involved circuit thus leaving enough time for fruitful experimentation
- The OLS-2000 overlay learning system is compatible with K&H products of IDL-800 digital lab, DT-01 digital trainer, ETS-5000 advanced digital system and ETS-7000 digital-analog training system
- No add-ons are required. A standardized set of all necessary components is included. The thoroughly course software was designed by educators with over 20 years practical teaching experience. However, the experiments are especially stressed on the theory . The professional manual is referred to the most widely used theory books
- The schematic diagrams component list and procedure are clearly offered. Each experiment was tested prior to final editing
- Moreover, the continuous hands-on exposure ensures the transfer of practical technical skills in the minimum time

Good overall
Color: White, Size: Standard (Pack of 2)
Bought these for our guest bedroom. They are quite overstuffed, so if you like full pillows this will be your thing. As such they are dense and firm. The height is a bit much if you are small framed, but are comfortable overall and stay cool enough to be nice in the summer.

Finally Found Pillows Everyone Loves
Color: White, Size: King (Pack of 4)
I LOVE these pillows. I bought the king-size set and ended up liking them so much that I want them on every bed in the house.
They’re soft but still supportive, and they actually work for different sleeping positions, back, side, and stomach sleepers. They don’t go flat, but they’re also not overly stiff, which is such a hard balance to find. I throw them in the washing machine which makes them super easy to wash! The size is true to King!
They feel cool and hotel-quality, and the down-alternative fill is great if you don’t want real feathers. I wake up without neck pain, and they keep their shape night after night.
If you’re picky about pillows (like I am), these are absolutely worth it. Comfortable, affordable, and a great value for a set of four.
