Using HTTP APIs to log data
Instructions from ESP8266 Arduino Tutorial, Part 3
We've all heard of HTTP - it's in the browser bar right now! But what is HTTP, really, and how can we use it to send data to a server? Well, HTTP stands for HyperText Transmission Protocol. It runs on top of TCP, or Transmission Control Protocol. You...

Unruly amplification: Turn up the music!
Instructions from Open Source LiDAR - Unruly
The returning photons are focussed onto the APD by a lens and optically filtered to reduce the background noise. The APD converts the photons into electrons but unlike a regular photodiode the APD operates with a high revers bias voltage (130 V). This...

Build details for mask intercom and exhalation filter
Instructions from A P100 Mask Intercom
At the start of the project, I had 3 identical P100s, all bought before the pandemic. They cost the equivalent of $47 US apiece in Ontario in the fall of 2019. The microphone is a repurposed pair of earbuds. Not only can earbuds convert electrical oscillations...

PORTs - How to use them?
Instructions from Getting Started with TivaWare Launchpad - Basics ⚓
Ports are the peripheral pins on an embedded system, or SoC to communicate with the external environment. Whenever a port receives a HIGH or LOW signal, it communicates throughout the system. A PORT is usually bit-packed, i.e. each port is represented...

Affordable Reflectance Transformation Imaging Dome
Instructions from Affordable Reflectance Transformation Imaging Dome
18. Preparing the LED connect cables for testingNow that all the LEDs are wired up, there are two simultaneous tests that need to be done:1.Test the LEDs to make sure they’re all wired up and working properly2.Test the MOSFET/CAT4101 driver board combination...

Analysing the code
Instructions from ESP8266 SDK Tutorial, Part 3
As we've established in prior tutorials, every program written with the ESP SDK needs to have a function called user_init(). This function is called by the SDK once it has finished the boot process. Much of the code in our example revolves around getting...

Mechanicals
Instructions from Basic Farm Robot 2021
In previous projects we spent a lot of time designing and building the mechanical systems and we really wanted to short cut all the hard work by using a ready made system that could be bought reasonably cheaply 'off the shelf'. We looked at mobility...

analog2pi
Instructions from analog2pi
Build it like this. Orange and purple are inputs, black is ground.CALIBRATIONNOTE: These instructions are for a character device kernel module. I will re-write them when I finish a proper sound device kernel module. They're also horribly confusing -...

ps2pi
Instructions from ps2pi
BUILDING ITYou'll need a mini DIN 6-pin socket to connect to the keyboard. It can be scrounged from an old keyboard adapter, or you can eliminate it altogether by cutting the connector off the keyboard cable and wiring it directly to the interface. Refer...

pi2meter
Instructions from pi2meter
FINDING THE RESISTOR VALUESolder a 10K resistor to the Zero's header connector hole at pin 12, and connect the other end to the meter plus terminal. The meter minus terminal is connected to pin 14. To test it type the following: sudo gpio -g mode 18...

▇▇▇▇ Real World Background ▇▇▇▇
Instructions from FPGA Bootcamp #0
Digital design with combinatorial gates like AND, OR, and NOT gates is relatively straightforward. In particular, when you use these gates to form combinatorial logic, the outputs only depend on the inputs. The previous state of the outputs isn’t important...

LoRaWAN Gateway and It's Working
Instructions from LoRaWAN Gateways tutorial | LoRa | What is LoraWAN
In the previous steps, we got to know that we get a LoRaWAN by connecting our LoRa based network to the Internet. But for connecting the LoRa network to the Internet, we need a LoRaWAN Gateway. One thing that needs to be mentioned here is that connecting...
