one of the more prominent jobs for novices in electronics is a power supply. Yes, you can always go to Amazon as well as buy a nice power supply, however unfortunately, we haven’t set up our Amazon affiliate links yet. Instead, we’ll have to go with the next finest thing as well as inspect out [Tron900]’s mini bench power supply build. It’s extremely capable as well as adorable as a button.
The style goals for this job were to develop a little as well as compact system utilizing mainly salvaged as well as recycled components, with all through-hole circuitry. the very best guide you’ll ever discover for a diy power supply is one of [Dave Jones]’ earlier video series going over the building of an adjustable power supply based on an LT3080. [Tron] didn’t have this regulator on hand as well as wished to base his style around an op-amp instead. After rummaging with his parts, he discovered what he was looking for: a TIP3055 power transistor, a neat enclosure that might double as a heatsink as well as an AD680 voltage reference.
The style of this power supply was simulated in SIMETRIX, as well as after a few revisions [Tron] had a circuit that worked fairly well. The circuit was populated on a piece of perfboard, a amazing front panel was constructed, as well as one of those ubiquitous volt/ammeter panels added.
This is just a one-off project, however the results are fantastic. This is a extremely small, extremely capable power supply that does whatever [Tron] needs. It’s precise enough, at least when determined with a elegant benchtop HP meter, as well as looks adorable. What more might you want in a benchtop power supply?
