Win a Tenma Power Supply

Congratulations to our winners!

Wow! You guys came up with some really creative ideas! There were over 100 individual ideas submitted and they were a blast to read through.

The winner of the Tenma Supply is Andrew J!

His submission literally made James laugh out loud: turning the supply into a mouse to scare a cat.

Congrats on your new supply!

But that's not all! We're going to find some element14 Community swag for the following honorable mentions:

This giveaway is closed.

Now that you know the basics of how to use a power supply, wouldn't it be great to have one to use on your very own bench? Well, you are so lucky because James has one to give away!

Unsupported video URL format.

James is always looking for novel ideas for how to use the equipment on his work bench. . . so in this contest, he's asking for ideas on the most unique use for a power supply that maybe isn't just using it as a power supply. (I don't think he means gutting it and using it for a potted plant.)

Add your suggestion in the comments below (no later than Friday, November 1) and you're entered with a chance to win.

James will select the winner and announce her/him on this page no later than November 14, 2019.

Another use of the TENMA as current source could be to measure the conductivity of solutions or metals. And having two "current sources" to compare the measurements against a reference in the same conditions. It could be worth, for example, to help control the salinity of a solution, or for quality control through conductivity comparison.

You can use this power supply to simulate the behavior of different batteries to check the response of your circuit.
Use the discharge curves of the batteries and check your circuit in cases that are difficult to simulate.

This power supply would be perfect for Copper Electroplating!

I made a setup at home with basic materials and a similar power supply for copper plating. You can also use it to other metals.

To qualify as an entry for this contest, your comment must describe a novel use of a power supply. (Besides just using it to supply power to a project.)

Simply saying, "Pick me!" or "I want to win one!" does not suffice. Sorry.

Get creative!

YES, YES, YES! That is me excited for a free power supply.

Can you use your power supply and your experience to design me a DC power bus system. I have multiple Pi's in a model railroad layout. The wall warts are growing in proportion to the Pi's. Now I have a race condition on some Pi's were the interfaces the Pi's feed get power before the Pi's causing the Pi to fail to boot.

I realize this takes the PS from a bench but during development the robustness and protection provides freedom of design.

I'm looking for a BoM for the project (i.e. your recommendation for parts) if that is possible. You would need to consider all levels of Pi's. The layout has all versions.

That is a very good PSU!
