Frequently asked questions
Can I power a 12V LED strip with this adjustable transformer?
Yes, set the voltage to 12V using the potentiometer and check the LCD display. Ensure that the LED strip consumes a maximum of 2A (24W at 12V).
How do I know what voltage to choose for my device?
Consult the device's label or specifications — the digital display shows the set voltage in real-time, and adjustment is made gradually to the correct value.
What happens if I exceed the maximum current of 2A?
The power supply has overload protection and will automatically shut off to prevent damage — do not connect devices that consume over 2000mA.

Inspired to create a chair where the backrest and armrests are molded from a single piece of plywood
Inspired to create a chair where the back and arms are moulded from a single piece of plywood, Hecht and Colin describe employing a process similar to that a tailor might use to cut a pattern in fabric. This approach resulted in the beautiful structure wherein the moulded back and arms component is supported by a simple A-frame wood dowel construction. One of the benefits of this design is an increase in comfort due to natural movement in the plywood back.
