Tell us about yourself!
TPMS reset device can be had for under $20 on eBay so you can keep your tire location set without a need to make a trip to a tire shop if you rotate, or switch out tire/rims between summer/winter, and my aftermarket TPMS sensors were less than $15 each, also from eBay. Personally I like being notified when a tire is low. If a battery has failed in a sensor it certainly isn't that expensive to replace the sensor anymore.
Very cool, hardware monitor. I just use tge "WhatsUp" app on a pc to ping every critical device on my network. Monitor stays on 24/7 and if something goes down it sets off a siren.

I second that idea. Put together the entire kit of the project w/ sensors, sans battery.
Love this, please show us a DIY option for switching DC loads. Thanks again for this, because I knew China solid state relays usually don't hold up to the ratings published.
Now if you can find an old CART monitor, you can make a visual display of your music, by applying the sound leads to the two coils on the yoke of the tube. Keep the High Voltage part of the monitor alive, and it will show a circle of sounds, as the left channel is applied to one coil, and the right channel to the other coil. I used to make these and sell them to friends.
And these, if I want solar charging, and emergency lighting along with the USB power ports: http://www.ebay.com/itm/Multifunctional-Camping-LED-Light-Solar-Power-Bank-Charger-Case-Box-DIY-Kits-Set/263062135915?ssPageName=STRK%3AMEBIDX%3AIT&var=562063418452&_trksid=p2057872.m2749.l2649
I buy these kits for very little money, and use salvaged 18650's from laptop batteries: www.ebay.com/itm/2-1A-4USB-Power-Bank-Case-6x18650-Battery-Charger-DIY-Box-Case-Kit-for-Phone-New/142247239419?ssPageName=STRK%3AMEBIDX%3AIT&var=441310653950&_trksid=p2057872.m2749.l2649
Loved this as a kid, but watch out for the yellow snow....

I use powdered citric acid, instead of salt or baking soda in my HHO generators. Same stuff Estes Model Rocketry uses in its hydrogen rocket.
