Description
DC to DC Converter Soldering Kit, Teaches the Basics of Switchmode Circuits (Intermediate Skill Level)This do it yourself soldering kit is designed to teach the basics of switch mode circuits. Includes all the components needed to build, along with illustrated assembly instructions. Once assembled, you can generate regulated +12V and 12V voltages from a 9V source such as a 9V battery Test points are provided to view switching wave shapes on an oscilloscope. An on board 1 Ohm resistor in series with ground allows measurement of current drawn from 9V
- This do-it-yourself soldering kit is designed to teach the basics of switch-mode circuits. Includes all the components needed to build, along with illustrated assembly instructions.
- Once assembled, you can generate regulated +12V and -12V voltages from a 9V source such as a 9V battery
- Test points are provided to view switching wave-shapes on an oscilloscope. An on-board 1 Ohm resistor in series with ground allows measurement of current drawn from 9V supply. Calculate efficiencies at various loads. Outputs can have an isolated ground or a common ground with input via jumper.
- Intermediate skill level - requires some previous knowledge of electronics, as well as good soldering techniques for medium dense boards. Assembly with a soldering iron is required (solder and soldering iron are not included).
- Requires a 9 volt battery (not included)

My New Toeless Socks
These toeless cotton socks have been my go to socks, I have had twelve surgeries on my foot due to a car accident on my right foot. I cannot wear close toe socks as the cause swelling and pain, now I can wear these soft toeless socks with no pain or swelling. I love I have the option of three different colors as well.

These boot slippers are awesome!
Color: Long Black, Size: 10-13
Love 'em!
FINALLY found these after lots of searches.... I wanted "boot" type slippers FOR MEN, so in the cooler/colder weather my ankles stay warm, as well as my feet. (It's easy to find them for women, but for some reason pretty difficult to find them for men.) Well, Amazon must have added these recently, because I had checked a number of times this past winter/spring to no avail.
At any rate, these are GREAT! I had worn out another somewhat similar pair I had found on Temu a while back, but they were rather floppy and really too large and wide for my feet. After a year or so they had worn out, so I started searching anew, and found these on Amazon. These fit just great and are very well made, having a thick fleece and padded sole inside and a non-slip sole on the outside.
Very, very comfortable! Just what I wanted, and kudos again to Amazon!
