The worst tablet known to mankind has to be seen to be believed, but beware, you'll never un-see it!48
One such device that stands out like a sore thumb among the crowd of perfectly adequate, low cost tablet computers, is the technological abomination called the Esinomed Infoview Medical Tablet Computer. This barrell bottom of design elegance and electrical engineering is designed for use in hospitals, displaying medical data about patients to doctors and nurses. All is fine and well on the outside, but tearing down this beast unravels a maze of technological torment before us.
Above all, the tablet looks not like a finished, shipment-ready product, but more like a hacked together prototype produced in a garage. Yes, this is how Apple and other technological greats started down in the Valley, after all! But compared to the efficient, miniaturized elegance of an iPad's insides — or heck, any modest, no-name tablet's build — this right here is an incident in the waiting!
The battery pack living inside this thing is a literal pack of rechargeable AA batteries, soldered and taped together into an amalgam of electricity and regret.
The journey through this mess starts with the first eye-poking detail, a hand-etched board for the power supply. Was someone in a hurry, or overly eager for DIY experience? For better or worse, we'll never know. Moving on, we get to an off-the-shelf embedded PC mainboard, based upon an 800MHz AMD Geode NX800LX Nano-ITX Motherboard. This is about the only adequate component ticking inside this Windows XP-running time bomb, and it gets progressively darker from here on.
Sifting past some chopped off wires, EEVblog's David Jones points out that the case holding this thing together seems to be made of plywood or other unsightly material, only to pull off a controller board that has a USB cable soldered right onto it, just like that. The board is stuck to the bottom with double-sided adhesive tape...
Yes, double-sided adhesive tape.
And then, we have the power supply's output soldered directly to the mainboard. What is it that supplies the power, though? You don't want to know the answer, but we'll give it to you anyway. The battery pack living inside this thing is a literal pack of rechargeable AA batteries, soldered and taped together into an amalgam of regret and electricity. Mind you, there aren't even sockets between the batteries — they are directly soldered to each other, connected with whatever wires were floating around the shop.
We rest our case here and sign off with the disturbing knowledge that there are at least 11 units of the Esinomed "What The Heck" Computer in existence, and some of them could even be in operation some place, somewhere. See the gruesome photos and video below yourself, if you can handle them!
