ADS7816 – 12-Bit High Speed Sampling AD

The ADS7816 is a 12-bit, 200kHz sampling analog to- digital converter. It features low power operation with automatic power down, a synchronous serial interface, and a differential input. The reference voltage can be varied from 100mV to 5V, with a corresponding resolution from 24mV to 1.22mV. – From TI Applications

ADS7816  – 12-Bit High Speed A/D Converter

Low power, automatic power down, and small size make the ADS7816 ideal for battery operated systems or for systems where a large number of signals must be acquired simultaneously. It is also ideal for remote and/or isolated data acquisition.

12-Bit High Speed Micro Power Sampling Analog-to-Digital converter

The ADS7816 is a classic successive approximation register (SAR) analog-to-digital (A/D) converter. The architecture is based on capacitive redistribution which inherently includes a sample/hold function.

The converter is fabricated on a 0.6µ CMOS process. The architecture and process allow the ADS7816 to acquire and convert an analog signal at up to 200,000 conversions per second while consuming very little power

The LMH0356 Serial Digital Interface (SDI) reclocker is designed to recover a clean clock from a serial digital video signal which may be contaminated by jitter and to resynchronize the input video data to the recovered clean clock. The LMH0356 SDI reclocker accepts signals conforming to standards SMPTE 259M (C), SMPTE 292M, and SMPTE 424M.

Texas Instruments – wiki

TI produced the world’s first commercial silicon transistor in 1950, and designed and manufactured the first transistor radio in 1954. Jack Kilby invented the integrated circuit in 1958 while working at TI’s Central Research Labs.

TI also invented the hand-held calculator in 1967, and introduced the first single-chip microcontroller (MCU) in 1970, which combined all the elements of computing onto one piece of silicon.

gEDA Project – Open Source EDA

The gEDA project is working on producing a full GPL’d suite of Electronic Design Automation tools. These tools are used for electrical circuit design, schematic capture, simulation, prototyping, and production.

gEDA – Electronic Design Automation

Currently, the gEDA project offers a mature suite of free software applications for electronics design, including schematic capture, attribute management, bill of materials (BOM) generation, netlisting into over 20 netlist formats, analog and digital simulation, and printed circuit board (PCB) layout.

Automobile Ideas from 2002

Cars should be aware of their environment and display status in the dashboard. It is like having cameras all around. The objects around and their direction of movement and acceleration.

Simple Automobile Safety Radar

There must be a very affordable automobile radar with just a 10-20 feet radius around the vehicle. This should display as a graphic on the dashboard as some of the very old 2D car games. This radar must be based on sonar or infra red to avoid additional EMI-RFI pollution and confusion. The display should show all objects which include people, small animals, kerb and wall.

The sensor has to be a multiple sensor, static belt one near wheels and one at the roof of automobile. The display device on car should be TCP-IP so that you can monitor your vehicle with your cellphone, PDA or any browser.

Automobile Ideas from 2002

Cars can have multiple skins like Winamp

If you use organic flexible LEDs, encapsulated in transparent poly-sulphone or some silicones. And the RGB triad matrix of LEDs are driven by a computer system to make it work like a flexible LCD screen. It can be used to form a skin for a car. Only there will be no high resolution, but it will do.

This flexible layer is fixed on the car like a permanent cap. Now with the onboard graphics synthesis embedded car computer you can choose any jpg, png or gif textured tile or make your own. Then output the tile or wallpaper to the car exterior LED matrix skin. Now the Car has become skinnable. Not just colors but fine textures are possible.


Now with a Bluetooth enabled Human Mood Monitor plugin you can make the car exterior to reflect the mood of the life-forms inside. This will make a road alive and traffic jams very colorful.

Storage Tripod Hybrid for Reliability Speed

The wear and tear, fragmentation on HDD can be reduced using a Tripod Hybrid. Access Speed improves too…

Top Layer is RAM Drive with Li-ion Battery. Second layer is Flash. Third is the Spinner HDD.

All active files of user are on RAM drive and backed up on Flash by intelligent Drive (not CPU). The files go into HDD after they have been stable for over an hour. As HDD sizes are increasing. The files and file system can be like svn and maintain 3 versions of all dynamic files. This is useful for user also and HDD too.

Storage Tripod Hybrid for Reliability Speed

Static files like Binaries can be on one area of HDD. Frequently accessed binaries are promoted to flash layer. Extremely frequent to Ram Layer. The HDD now is less stressed and lasts longer and is a stable backup. Power failures immune.

Bare Essentials

A supercap built into a HDD. On Brownout OR Power Fail. The falling ramp is detected beyond an isolating diode. It says to HDD uC … Look there is something funny with power now. The HDD uC at once finishes the work at hand, drawing its juice from the stable supercap, parks its heads and goes to sleep.

When power is stable again, it wakes up and the supercap is replenished too. This way damage to HDD is avoided, these happen when .. battery connection problems in laptop or mains power fluctuations or switching power systems carelessly. It makes HDD idiot proof at least electrically.

Speech to Text and Text to Speech Devices

This was an idea for Apps like Browser and Email..This is for any device phone or laptop a user interface for people who need it like when Cooking or Driving. People with disabilities or injuries. BlackBerry Phone had a nice incorporation of the text to action.

Added in 2015

We have three things Text-2-Speech, Speech-2-Text and Speech-2-Action. This makes any Gizmo or Computer Interface with a Human without the use of Limbs.

2009 Note Below –

Spoken Words or 14 Seconds of Voice Message. Alternative to Thumbing. A Text to Speech Engine Server Side. With Adaptive Mimicry Voice Synthesizer for that User ID. .

A MultiMedia Service without too much local or server load. Short Compressed Audio Files Recorded and Rendered by Flash Inline Inserts on the Web Application.

First idea enables people who just cannot type their message, and need to speak a few words, which is recorded by microphone and sent like a Compressed Voice mail.

Second Idea depends on first idea to train a server side engine, a Text to Speech tuned by earlier voice messages.

When a person cannot read the text, like when driving or in a private gathering, he can press read all incoming messages. Then the server will process text to speech matched according to the User ID Speech Profile and Read out loud in his Headphones.
