Please Don 39;t Touch Anything References

Case 2 : Input(Non inverting) = 0 to 3.3V, 100kHz, 50% duty, Vref1(Inverting Input) = 3.5V to 5V. Tested at different levels and output is same as attached waveform. What could be the cause of this unintended pulse and how to overcome this?
it's very simple: The TLV3202 is a high speed comparator and you must treat it like a HF-OPAmp. So, you will probably need a solid ground plane, very shortest traces, suited filtering here and there and shielding. Please don't connect cables (or, even worse, wires) to the inputs unless you introduce 50R signalling. Provide a hysteresis and add an isolation resistor to the output of TLV3202 as shown in figure 30 of datasheet. And please don't directly touch anything of the circuit with the scope probe. Insert a 47...100R resistor first.
So, an ultra fast change rate of voltage causes a huge current spike into the stray capacitance which can erode the signal ground, cause internal ground bounce and result in ringing and resonances across parasitic impedances (signal trace inductances, stray capacitances, etc.). Ground bounce can even make the comparator oscillate!
The oppressive-looking desk job reminds me of Papers, Please (and so does the 'please,' obviously), but PDTA's sense of humor makes it a bit more like The Stanley Parable, if you reduced Stanley's repetitious adventures into buttons and switches. The narrator in this case is a colleague who tells you not to touch anything before shuffling off to the bathroom. The first thing I did is start pressing buttons, naturally.
PDTA is about unraveling the odd workings of a convoluted machine to activate surprises. Most of the puzzles require thorough study of the brief, cryptic instructional poster in the upper left, as well as enough curiosity to try, err, and try again. 'I'm just going to do this to see if anything happens' is the best way to discover the simpler solutions, and always a good idea when left unattended with machinery.
There's not much 'content' in the traditional sense, but that's a word I revile anyway. The 'content' is what you do: PDTA is a puzzle box, and the things inside the box (brief animations, mostly) will only disappoint if they don't come as a surprise revealed by fumbling through the solutions. There's a complete guide on Steam, but just glancing at it deflated a lot of the mystery for me. So, don't do that.
After the title screen, you will appear directly in front of a console with a red button within what appears to be a small office room. You will hear a door open to your left and will be greeted by a waving arm (presumably your work colleague). He will inform you that he needs to take a bathroom break and that whilst he is gone, you are not to touch anything.
Now I would normally recommend having a little play around with the game before hand so that you can get a feel for the game before starting this walkthrough, however if you have already played the game and/or just wish to get the achievements in as little effort as possible, continue ahead.
I will start off by focusing on the 'Perfectionist' achievement which requires you to obtain all of the 30 unique endings without pressing any unnecessary buttons, so please follow the guide exactly as I have it displayed below. I also list these endings starting off with what I believe to be the hardest endings first. Some may require a little practice, but the endings get easier as the walkthrough progresses.
Before starting this walkthrough, it is worth taking note of a few things which may help you understand what may or may not count as an action that may result in a failure and require a complete restart. Here is what I have found:
It DOES NOT count towards failure if:
- You spam the hammer at the bloody blobs for ending #16.
- You click several times all over the panel to find the red arrows for ending #22.
- You end up grabbing the hands on the clock multiple times for endings #17 and #25.
With this being said, I would also advise that you carefully read each 'Ending' and get a vague idea of what is required of it. If you accidentally click a button that is not part of the sequence, you may be forced to reset the playthrough by deleting your save file and starting again.
Press the red button again to reveal a 3 button panel.
Enter the code 312213 in the new panel to reveal a lever.
Pull the lever to the left to reveal a ten-digit panel.
Enter the code 8008 in the new panel to reveal a panel with a date and two buttons and a floppy disk drive.
Press the red button another 14 times to reveal the hammer.
Drag the hammer to pry the top right desk drawer to reveal the 'City Boom!' floppy disk.
Grab the floppy disk and insert it into the drive slot in order to boot the 'City Boom' game.
Click on the monitor screen to start the game. Complete the game without missing any bombs.
A message pops up saying: "YOU DROP ALL BOMB".
Whack-A-Mole Ending #16
Press the red button 16 times to reveal the hammer.
Drag the hammer to the red button.
Hit the button with the hammer 3 times to reveal a bloody fetus in the center.
Hit the fetus once and then continuously hit each sac that appears out the console 3 times until each sac explodes.
Hit the fetus again to reveal more sacs. Repeat this process until they are all destroyed.
You'll beat it when the baby explodes and the window goes green only showing three symbols, these symbols aren't needed for anything.
NOTE: The game is timed by a trail of blood leaking towards the restart button, so try to be quick.
