24V to 5V 10A 50W DC DC Converter Regulator Car Step Down Reducer 24V to 5V 10AMP Daygreen CE Certificated (WHL #46)

Alright, part two of the DC-DC converter tests that’ll lead to a small project. This time we got a 5V/10A converter from Daygreen, model number B10-1224-05, shipped together with the 12V/10A unit from WHL #44. This item was 2.41€ excluding shipping, as described in that blog post.

It’s a brick style unit as well, a tad smaller, but also has two mounting holes left and right which are flush with the case. Contrary to the more powerful 12V one, this is only a plastic case that was potted, but it has four screw terminals and therefore offers more flexibility when it comes to attaching your own wiring.

…and I don’t think I paid that much of a premium for it. So today’s item is a step-down converter model “D121” rated 10 amps at 12V, with 15-32V input voltage. Price was 2.86€ at the time; contrary to the usual item on this site, this was without shipping cost. […]


DC Jack Powerbuchse Netzteilbuchse Strombuchse IBM Lenovo ThinkPad SL400 (WHL #9)

Heyho!

Today’s item is one that I needed for my smallish light box. I had some makeshift connections when building it, including one with a fixed 65 W (original!) Lenovo laptop power supply who unfortunately had a loose power plug. When I finally had three illuminated sides up (with the stuff from WHL #7), I knew I needed to step up to 90 W or even 135 W power supplies for full brightness. But this time, I wanted a detachable power plug, especially to not kill the power supplies for normal use, but also for convenience (the box is quite large and the supply is too heavy to attach it somewhere).
