SonarPen: A cheap, pressure-sensitive stylus for sketching on older iPads

A recent study disturbingly revealed that young children are using touchscreen devices so frequently that they are growing up unable to hold pens correctly due to underdeveloped muscles. Despite there being several electronic pens on the market for use with tablets or smartphones, they generally have been either expensive or limited to newer tablets. A Hong-Kong-based company hopes to change all that with the SonarPen, a cheap, pressure-sensitive stylus that works on almost all generations of iPad, connecting to the devices through the headphone jack.
