30M. It's hard to describe but time to time I feel some kind of sudden pressure in my neck and chest and I feel the urge to inhale. First I thought it is heart related but now I feel like it has something to do with the trachea, maybe some kind of contraction. It is not painful but a bit unpleasant and it comes more frequently when I'm laying and have my head tilted forward (looking at phone in bed for example). It is sudden and lasts just half a second or less. What symptom is this? What could be the cause and what examination should I do? I don't smoke and I haven't noticed other symptoms.

I have an aging desktop PC with an i3-3240 processor, Radeon HD5700 graphics card and 8 Gb DDR3 1600 MHz ram and an Asus X555L laptop. The PC is starting to get some motherboard issue, I always have to press F1 on startup and save the settings in BIOS, maybe a capacitor is getting old.

I would replace these two with a Lenovo Ideapad 5 with i3-1115G4 processor and GeForce MX450 2Gb dedicated graphics chip and 8 Gb 3200 MHz DDR4 ram. My budget is under 500$.

It looks good on paper but I'm not sure how to compare laptop with desktop PC performance. I use my current devices for browsing and watching HD movies and ligthly game on them, the most demanding games so far were Overwatch and WoW.

I installed a bluetooth kit in the car that connects to the aux port on the back of the HU. I can connect to this bluetooth kit with my phone, but i cannot access aux mode on the radio. When I press the media button nothing happens. I have the 6 cd changer type unit. What could be the problem?

Velocipede mountain bike

Invention Idea Submission

Hi! I was wondering how it would look like if you built an old velocipede (with the huge front wheel and small back wheel) with modern mountain bike tires, brakes, telescope and other parts. The velocipede is completely unsuitable for mountain terrain, but you could see the nature from a higher seat :)
