Construction and design
So, we pass straight on to our subject under discussion. The case of the device is really very compact, its size (70x70x37.5 mm) can be compared to a packet of cigarettes, for instance. Its mass including a battery doesn’t exceed 212 grams. Main parts are made of regular plastic with different types of processing.
The bottom part of the projector is nothing more than a removable li-ion battery with the capacity of 10.95 Wh. The battery has a regular opaque case with rubber legs so that it can be installed on any kind of surface.
It is fastened to the body with the help of small latches and there is a button on one of the side panels for removing it.
There is a screw fixing on the bottom which is used for tripod. The plug is made of metal, therefore there’s no doubt it is solid. The thread diameter and the thread pitch are the most standard, so you can use a tripod of any kind: for a photo camera or any other.
The body is glossy while the top panel looks like metallic. Here you can find numerous touch sensitive selection buttons for adjusting a projection and operating the projector. When it is on, the buttons are illuminated from beneath with low-profile blue light. The button stroke is quite accurate but if you press a button at the side, the chosen function may not be activated. However, anyway, this system looks much more efficient and interesting than regular buttons.
The biggest part of the side panel surface is occupied by ventilating grills because while being operated the device get considerably warmer. There is a small lens on the front side and it is used for displaying image, and there is a knob for optimum focus control beside. It is used if a projection distance changes. In theory it can be up to three metres.
There is a loudspeaker of 1 watt for reproducing sound but you should take into consideration that the quality of the sound is rather moderate. Therefore if you are going to have a presentation with a good quality sound, you’ll have to get additional loudspeakers.
The main ports are on the back panel under a small cover. The signal is transmitted from the computer D-SUB output with the help of an adapter connector. It is also possible to use a regular composite output that works with NTSC 3.58, NTSC 4.43, PAL, PAL60, PAL-M, PAL-N, SECAM systems. There is an audio output here as well and a slot for an outer power adapter. It would be great to have an HDMI interface supported.
There is an embedded memory of 1GB, only 700 MB of which is available for using. It’s not a huge disadvantage as you can connect any widespread carriers to the pico-projector. Firstly, there is a microSD card slot. Secondly, you can use any USB flash drive via adapter connector. You’ll find it in the delivery set.
On the whole everything looks well-thought-out. The support of different data carriers is especially impressive. In conclusion it should only be noted that there is a durable case bag for daily transportation included in the delivery set. Unfortunately only a pico-projector and a battery can fit in it. All the cables and a network adapter have to be carried apart and it is an obvious fault. We’d like to have a case bag that can hold all the necessary things, though.
