Blink camera external battery

Article in progress... 

This article covers most of information and pictures documenting my road to longer battery life and recharging facility of one of the popular camera doorbell.  

It consist of 4 parts:

1. Battery dummy with connecting points (provides non-invasive way of connecting wires into camera)

2. Battery charging and protecting unit

3. Built-in pushbutton battery voltage tester 

4. 18650 battery pack 

All sits in my custom-made 3D printed box fixed indoor, on door frame opposite side of doorbell installation place (for minimal wire length and convenience).

Hello world with ADS1298

Image
Let's make first simple communication with ADS1298 (delta-sigma ADC). To confirm communication with this ADC, we will ask for its ID.   Hardware To talk to ADS1298 we will use SPI and bcm2835 library. SPI is an intuitive solution here. ADS1298 is capable of 20MHz SPI communication, anyway due to Raspberry Pi problems with SPI speeds higher than 16MHz we will stay on 8MHz (7.8125MHz exactly). To provide this basic communication connectivity we need an SPI (hardware) connections with separately defined /CS signal. This is due to inconsistency in providing spacing between end of CLK and rising end of /CS.  We will use RESET signal as well. Be aware that to establish communication with ADS1298, there is a need of both, simultaneously: CLK (in range freqency  from 1.945 525MHz to 2.415,459MHz) and SCLK (SPI clock: max 20MHz when powered 2.7 V ≤ DVDD ≤ 3.6 V and 15MHz when 1.65 V ≤ DVDD ≤ 2 V). This may be counter intuitive, but from experience: it is a mus...

matplotlib and Raspberry Pi 3 - show my 'Hello world!'

Image
17 April 2018 Here it is: I have tried to do simple plot using matplotlib on freshly installed Raspbian (jessy). Way to accomplish this seemingly easy task is quite bumpy thou. This post serves to document the steps i have done to see the plot first time. 1. grab a Raspberry Pi and all peripherals 2. If you have an NOOBS SD card, install Raspbian, if not, visit  https://www.raspberrypi.org/downloads/noobs/  and  download NOOBS, follow the installation procedure. 3. Raspbian installed? Great. This is Linux named Debian, to quickly check what you have installed open terminal and type lsb_release -a  As answer you obtain something like: Distributor ID: Raspbian Description:     Raspbian GNU/Linux9.4 (stretch) Release:           9.4 Codename:      stretch Start from typing a command: sudo apt-get update Check the python version you have by typing in terminal  python or  pyt...

Data collection from ADS1298

To collect data from ADS1298 the previous setup will be used. Data will be formatted. What is received from ADS1298: 3 bytes status + 8 groups of 3 bytes (for each channel). Because value of each channel is 24-bit it will be manipulated to fit into 32-bit integer value. Again, you need CLK and SCLK clock (both) to establish communication between RPi and ADS1298. For plotting purposes first column of data will contain time stamps. /* * Code to perform communication with ADS1298 * * ads1_1 - basic communication established. ADS gives an answer to Raspberry Pi B through SPI bus. * ads1.3 - read device signature, reset introduced, basic initial settings, generating test signal and printf of one channel and one value * ads1.4 - preparation for pipeing to continously give one channel value out * * ads2.0 - seperated files, 'manual' control for /CS chip * ads2.1 - output now: saving to file (to allow use with kst2 - fast plotting program) * ads2.2 - time stamps * ...
