I have been an Android developer since late 2009 and finding out every apartment was controlled with an Android tablet got my curiosity. In theory, it seemed like a great idea - why not use a fully developed project like a Galaxy Tab and attach...
It turns out the dirtycow exploit is a complex thing with many possible implementations: https://github.com/dirtycow/dirtycow.github.io/wiki/PoCs dirtycow-mem.cI tried them all out and was excited by the supposedly "memory-only" PoC but realized it still...
For testing the performance of the tracker I'd want to leave one in my car. But it contains a rechargable lithium battery and I'd feel much better if it could alert me if the temperature is outside the battery's recommended range.To make no changes on...
Lately, I've discussed with @★ STMAN ★who is very knowldgeable about computer security and I'm starting to see old problems with a fresh, new and promising angle. Cue opening theme.The trivial.Code is not data and vice versa. FC1 is a Harvard system...
A game console is nothing without some form of output, and LCD displays are expensive for the size I want. Lucky for me, a friend of mine gave me an old printer to tear apart, and now I have an LCD that very conveniently has an LCD controller board already...
This project didn't start off with a big huge press. Time to go back to basics. I had started off with this Short Jack, 1/2" of lift rated at 9,250 psi, with a piston 3" in diameter. Actually perfect for my needs. When I initially tried to change the...
So far we've defined an assistive technology product for integrating interactive lighting into spaces for the mobility impaired. Now we can start hacking to figure out what needs to be done in order to get this implemented! The main challenge here is...
one of the biggest delays to getting terminal information to output is that it needs to work at separate times from the i2c bus and spi bus. spi bus is fast enough that this should not be an issue with outputting to lcd display. I want the terminal data...
The possible loss of functionality of the face masks after physical disinfection is a crucial consideration in order to evaluate the viability of such practice. Radiation and heat could definitely affect the materials of the mask, rendering it unsafe...
So the PCB fabrication worked out nicely. I recently switched from using the toner transfer method of home fabricating PCB's to the UV exposure method because I wanted to make compact boards with small SMD components. My experience with toner transfer...
Wireless nodes are part of OHS ecosystem. They serve as source of data from sensors, and as receivers for inputs. Inputs represents relays or other devices waiting for incoming commands. If you want to connect wireless node to gateway you need to set...
Let's Make Robots (LMR) has new owners. The transition to new owners did not go very smoothly. I've received an apology for being blocked from the site so I've editing this log. (Edit: On 21 Sept., 2015 I ended my membership with LMR. They wanted me...
Heather got a new wheelchair a year or two ago with a tilt feature. It helps her pain immensely to be tilted back, and the control to tilt back is relatively easy for her to manipulate, so she stays that way most of the time. Unfortunately, she can't...
We sent a Tracksoar to a team out in Texas who were putting together their first ever high altitude balloon launch for a contest. They had only a week to put it together so we sent them one of demo boards. Within just a few minutes of receiving it they...
The last version was quick and dirty and as it could be expected, it has a few shortcomings. So much in fact that it's better to do it all over, it's faster than trying to fix it.The second time I do something, I don't want to have to do it by hand a...
