@thor It might be an SD or Science Doctorate, I believe MIT has PhD and SD programs.
There's also a stick on the floor. There aren't papers on the walls. It's rather odd.
@lupyuen Ah so the Mathematics involved is starting to show. Perhaps next up is proof.

@lupyuen It's rather odd that attempts are continually made to make weapon systems like these. A Threat Detection System integrated into an optic could have a more positive effect.
Assuming that both technologies would be used by police, the latter could prevent tragedies. The problem with the biometric systems is that they can't be relied upon. A flimsy laptop is consumer grade but military and police use Toughbooks.
It's really interesting news for Embedded Systems but certain smartphones have similar systems that have proven to be unreliable or easily defeated.
To be fair, it is rather cool to see. A violent force being exerted on electronics and the connectors could lead to more reliable connector designs and more reliable electronics. I can't think of a better proving ground than this.
@PawelK The whole design is based off existing products and easily sourced smartphone parts. There are a lot of cool stories from those directly involved in the development of the phone. Cameras had to be reversed to get working with open source code and the A64 was the most powerful SoC with the Mali400. It was as open source as possible.
@PawelK The Pinephone battery is removable. The whole phone is held together with 6 screws that are the same size. The back of the phone pops off for battery and switch access.
@PawelK That's a significant amount of power being used for each of those.
@PawelK Using wget for the HTML and loading in the parts desired would be easy on resources.
@PawelK Allwinner SoCs like the A64 are paired with an X Powers AXP 803 which controls charging and power use. There's also another PMU on the Pinephone. I think the other is used for faster charging and more advanced features.
@PawelK Pinephone uses the same battery as a Samsung J5 I believe. It's not a complicated connector.
@PawelK Infinitime had the same problem with the PineTime and its Nordic chip.
A cell phone would be very different. What Mr. Lee is working on could actually get closer to it if the Pinephone had a low power screen and a larger battery. There is likely a problem with that hardware revision too. It has enough control to where it charged at 5V 3A without issue for me. Two microcontrollers control charging of the device.
@thor That sounds like a good time.
@thor Neurotoxin isn't as serious as a Traumatic Brain Injury. Honestly it is up to the government and their pets to say if something is neurotoxic. Go fast if one wants, it's not as bad as people say.
@lupyuen Lattice chip so it can actually be used without being a lawsuit magnet. This is encouraging.

@lupyuen Good old Hayes Commands. How does one know if code is for a modem? AT commands. I'd highly recommend keeping these commands handy, one never knows where it can pop up.
@thor It really is a shame.
