Water Softener LED Display
Posted on: 13 Jul 2016
Many homes in the United States have water that contains higher concentrations of dissolved minerals, which is called hard water. Although there is nothing toxic about hard water, it is less desirable for cleaning, it leaves mineral deposits, and it can shorten the lifetime or efficiency of equipment such as water heaters. A water softener […]
RFID Car immobiliser with PIC12629
Posted on: 13 Jul 2016
Ok, so there are heaps of immobilisers out there but with most of them, if someone has your keys, they have you car. What good is a car alarm with 3+ point immobilisation if someone manages to get the keys and of course the alarm remote. This is a simple immobiliser based on a PIC12F629 and […]
GET A CONSTANT +5V OUTPUT BY SWITCHING BETWEEN A +5V INPUT AND A SINGLE-CELL LI+ RECHARGEABLE CELL
Posted on: 13 Jul 2016
Abstract: Design provides a simple method for maintaining an uninterrupted +5V even while switching between the external +5V supply and a rechargeable single-cell Li+ battery. Some portable applications need to be powered up from an external +5V wall adapter supply and still require a +5V system voltage when in battery-backup mode. This design provides a […]
IKEA Samtid mood-light upgrade
Posted on: 13 Jul 2016
This upgrade is based on the loved-by-everybody WS2812B intelligent RGB LED and works just fine with Adafruit’s NeoPixel library. The concept is – once again – rather simple. Whack a lot of WS2812B RGB LEDs onto a small board, add an ubiquitous ‘Arduino core’ and make sure everything fits nicely and works. Well, it worked. […]
Hacking the Xbox CONTROLLER
Posted on: 12 Jul 2016
In this tutorial I show you step-by-step how I install a PIC microcontroller inside of an Xbox controller in order to provide custom functions. Now that you have the methods, all you have to do is go write some code and program a chip! Well, I know this is easier said than done, but check […]
NES Controller iPod Remote
Posted on: 12 Jul 2016
By embedding a PIC microcontroller into an NES controller, it can be converted into a replacement for Apple’s iPod remote. (Only 3rd and 4th Generation iPods have this, it is a the small oval port next to the headphone jack). Update (8/26/2011): It’s been quite some time since iPods have used this iPod remote connector, […]
How to Control Your ESP8266 From Anywhere in the World
Posted on: 12 Jul 2016
Written by Rui Santos – Get free updates of new posts hereHey there,The most common questions I get about the ESP8266 WiFi Modules are: “Is it possible to control my ESP8266 from anywhere in the world?” and “How can I control my ESP8266 from anywhere?”.I’m happy to announce today that I have a solution for that problem.With the new version of Home […]
2-Wire Keypad Interface Using a 555 Timer using pic microcontoller
Posted on: 12 Jul 2016
Keypads are a very commonly used input device in microcontroller-based systems. In a keypad, multiple switches are arranged in rows and columns so that they could be interfaced to a microcontroller with a minimum number of I/O pins. For example, a 12-key keypad is arranged in a 4×3 format, which allows to interface the 12 […]
Crossed IR Beam Camera/Flash Trigger
Posted on: 11 Jul 2016
This device will trigger a camera or flash unit to automatically take a picture when an object (target) enters a specific location. It uses two, crossed infrared light beams to detect the presence of the target and close a relay that trips the camera or flash unit. Response time is about 2 ms from detection […]
Chip adds precision altitude sensing to mobiles
Posted on: 11 Jul 2016
Brief Description The ZSSC3016 is a sensor signal conditioner (SSC) integrated circuit for high-accuracy amplification and analog-to-digital conversion of a differential input signal. Designed for high resolution altimeter module applications, the ZSSC3016 can perform offset, span, and 1st and 2nd order temperature compensation of the measured signal. Developed for correction of resistive bridge sensors, it […]
