Pseudonymous maker “Tuenhidy” has revealed a information to turning an influence provide right into a useful transportable, modular coaching package with DIN rail mounts — and a framework constructed from low-cost PVC plumbing pipe.
“I had one PSU from [a] damaged laptop case, [an] AcBel CE2 400W,” Tuenhidy explains of the elements which went into his thrifty construct. “I assembled a PVC body with a deal with, it accommodates [the] PSU inside with dimensions L×W×H about 200×165×160mm [around 7.9×6.5×6.3″]. Any such PSU has two openings for air flow with fan at high and air flow holes at facet,” the maker notes, with the framework maintaining these clear.

It is the framework which actually makes the construct stand out, in actual fact. Fairly than utilizing an off-the-shelf enclosure, getting messy with metalwork or woodwork, or designing one thing for 3D printing or laser chopping, Tuenhidy opted for one thing easier but very efficient: push-fit PVC pipe, extra often used for plumbing work and accessible at a really low price.
A choice of T-pieces and 90-degree fittings are mixed with the pipework to construct the body to surround the PSU, with a carry deal with on the high. A chunk of acrylic hosts terminal blocks wired to the ability provide and an on-off swap, whereas two different sides maintain a DIN rail to mount different gadgets. 3D-printed adapters enable numerous gadgets to be related for coaching functions — from microcontrollers to prototyping boards.

“For additional growth, I can mount a 24VDC energy provide on the rail,” Tuenhidy notes. “All of the PVC fittings have openings holes at backside so I can lengthen my coaching package [vertically]. Simply stack extra PVC fittings and mount extra DIN rails.”
The complete write-up is obtainable on Tuenhidy’s Instructables web page.
