someone is selling an #iX104C3 #Tablet-PC for AR$37900 (US$190). They have 3 left. 5700 mAh battery. “Su pantalla brillante la hace ideal para trabajos aire libre, permitiendo además una transición perfecta de interior a exterior.” Wi-Fi 802.11 b/g.
another #Tablet-PC for AR$35000 (US$170) but this one isn’t industrial.
requirements for #Tablet-PC: minimum 100 Hz digitizer, detection of pen within 5 mm of screen, 600 points per inch and at least 5× greater than the LCD density
1-⅛” galvanized steel washers for AR$770/kg (US$3.85/kg), 18 per kg. They seem to be about 17/32” wide from measuring the image, assuming 1-⅛” is the inside diameter. That would make them about 2-3/16” in total diameter and 1800 mm², which for a mass of 56 g, would make them about 3.9 mm thick.
looks like I can get 2.5” parallel ATA disks still, though the prices are extremely varied
