The Atten APS 3003S/3005S is an entry-level power supply designed for use by hobbyist and by students in school labs. The two models, the APS3003S and APS 3005S are almost exactly the same, but there are slight design differences and specs between the pair. The 3003S features a maximum current output of 3A and the fan is constantly on. The 3005S model features a maximum current output of 5A and the fan is controlled by a thermostat, which monitors the temperatures of the heat sinks from the two power transistors and discussed later on. This series of power supplies is usually seen sold on eBay for a relatively cheap and fair price of around about $100, which means that it is easily obtainable for both hobbyist and school use. It can output 30 Volts at 3 or 5 Amps depending on the model and it does also have some very promising specs. Every lab needs a proper power supply for many purposes such as testing electronic circuits, charging batteries and for just burning things up :D. I’ve been needing a proper power supply for my lab for a while now and after searching for a bit I decided to buy this power supply because I was unable to find another power supply in the same price range with the specs that this unit offered. Now after receiving and using the power supply for a bit, I am able to provide a full review and a small teardown of the supply.
Some people like to use the iPad onscreen keyboard, while others find it easier to use a separate more “physical” keyboard. I was very lucky to obtain a Rappo BT Ultra-slim Keyboard for iPad E6300
, but also very unlucky to be able to use it only for a few days before its obvious flaws came out. So today we have a review and teardown of this wireless keyboard which made for iPad, can also be used for a Mac computer. Below is an overview on the keyboard.
