The Cybook (cyborg + book) is an experimental digital photo book build around a Raspberry Pi Zero and 3D printing. Version V03 contains a previously unpublished photo series from Tokyo. The order of the photos is random, with the slideshow being controlled by a rotary knob. By pressing the knob the user can generate a new, randomized series. This way, every user gets to see a different version of Tokyo.

Might as well jump on the bandwagon.

For every 100 notes, I do something.

100 notes - Draw more

200 notes - Do my nuzlocke more.

300 notes - Attempt a short and simple animation.

400 notes - Attempt to finish my nuzlocke.

500 notes- Write that pmd story I've been planning for some time.

1000 notes (nightmare mode) - Attempt 3d animation hell without Blender (my raspberry pi can't handle Blender)

Y'ever just think... wow... that's too many computers?

I have seven, not including my tablets.

Five of them are laptops.

Two of those laptops are Macs -- my current Mac laptop (an M2 Macbook Air) which I use every day, and my old laptop (a late-2011 13" MacBook Pro) which after some upgrades (and the removal of its spicy pillow battery years ago) currently runs as a backup server, print server, and network drive.

Then there are the three HP laptops.

One of them I technically don't own, as it's my work machine. It's just running Windows 10 -- nothing special -- and it works. Then I have my two fuckaround machines -- a 15 year old 17" 'desktop replacement' that originally ran Vista but currently runs Linux Mint (and we used for years as the registration computer at No Brand Con). Then I have a 14" laptop that's "current" (in the sense that you can buy it right now for less than $200 at Walmart) that I got for free -- which dual boots into Linux Mint and Windows 11.

And then there are the non-laptops -- my M1 Mac Mini (my primary production workstation for art and podcasts) and my non-laptop fuckaround machine -- a Raspberry Pi 400 running Raspberry Pi OS.

And I was realizing today... is that too many? That might be too many.

For researchers, I find that these Raspberry Pi cases and extensions are far better suited to community work, fieldwork, and note taking than laptops or smartphones.

Similiar to the appearance of laptop DJs, who tend to look like they are checking their emails while playing, it is an akward view to hide behind an illuminated screen as a researcher, if you want to be engaged with the people around you and the situation.

Plus they are easier to use while standing up or walking. And having a physical keyboard as opposed to a screen keyboard on a tablet or phone means you can keep your eyes up while typing.

Pi Power Revealed: What Your Raspberry Pi Really Costs to Run in 2025 In the ever-expanding universe of DIY computing and IoT projects, the Raspberry Pi remains a versatile cornerstone for creators, developers, and hobbyists alike. Whether you're building a weather station that runs on batteries, setting up a 24/7 home server, or creating an edge computing device, understanding your Pi's power consumption is crucial for success. With the diverse range of Raspberry Pi models available in 2025, power requirements vary significantly – and knowing these differences can make or break your project. This comprehensive guide delves into the real-world power consumption of various Raspberry Pi models, explores the factors that influence energy usage, and provides practical tips for maximizing power efficiency. Whether you're concerned about energy costs, battery life, or selecting the right power supply, we've got you covered. Understanding Raspberry Pi Power Basics Before diving into specific models, let's clarify how power consumption is measured. Power is typically expressed in Watts (W), which is calculated by multiplying voltage (V) by current (A) using the formula P = V × I. Raspberry Pi devices generally operate at 5V DC, with current draw varying based on activity level and connected peripherals. This means power consumption is dynamic – a Pi sitting idle might draw minimal power, while the same device running intensive computations with multiple peripherals could consume significantly more. Power Consumption of Different Raspberry Pi Models Raspberry Pi 5 The flagship Raspberry Pi 5, with its powerful processor and expanded capabilities, draws more power than its predecessors: Idle: Approximately 3.0-3.5W (600-700mA at 5V) Under load: 7.0-9.0W (1.4-1.8A at 5V) Notable features: The Pi 5 implements improved power efficiency per computation compared to the Pi 4, but its higher performance ceiling means maximum power draw is greater. The onboard power management IC offers better regulation than previous generations. Raspberry Pi 4 B The workhorse Raspberry Pi 4 remains popular for many applications: Idle: 2.5-3.0W (500-600mA at 5V) Under load: 5.0-7.5W (1.0-1.5A at 5V) Notable features: Power consumption varies significantly based on RAM configuration (2GB vs 4GB vs 8GB models) and active interfaces. Raspberry Pi 400 This integrated keyboard model based on the Pi 4 architecture shows similar consumption patterns: Idle: 2.7-3.2W (540-640mA at 5V) Under load: 5.5-7.5W (1.1-1.5A at 5V) Notable features: The larger form factor provides better thermal management, which can slightly reduce power spikes during sustained workloads. Raspberry Pi 3 B+ This older but still useful model offers moderate power requirements: Idle: 1.9-2.3W (380-460mA at 5V) Under load: 3.5-5.5W (700-1100mA at 5V) Notable features: More power-efficient than the Pi 4 series, but offers significantly less computing power. Raspberry Pi Zero 2 W This compact powerhouse strikes an excellent balance between capability and efficiency: Idle: 0.5-0.7W (100-140mA at 5V) Under load: 1.5-2.2W (300-440mA at 5V) Notable features: Remarkable power efficiency makes it ideal for battery-powered projects. Raspberry Pi Zero W The original ultra-compact Pi remains the most power-efficient standard model: Idle: 0.4-0.5W (80-100mA at 5V) Under load: 0.8-1.5W (160-300mA at 5V) Notable features: Perfect for ultra-low-power applications where computing requirements are modest. Factors Influencing Raspberry Pi Power Consumption Several key factors dramatically affect how much electricity your Raspberry Pi uses: CPU and GPU Load The single biggest variable in power consumption is processor utilization. Running intensive tasks like video encoding, machine learning algorithms, or complex calculations can double or even triple power consumption compared to idle states.

Connected Peripherals Each device connected to your Pi adds to the overall power budget: USB devices (particularly power-hungry ones like hard drives): 0.5-2.5W each HDMI displays: 0.5-1.0W per active connection Camera modules: 0.2-0.5W when active HATs and add-on boards: Varies widely from 0.1W to several watts Network Connectivity Active network interfaces contribute to power draw: Wi-Fi: 0.3-0.5W when active Ethernet: 0.2-0.4W when connected Bluetooth: 0.1-0.2W during active communication Overclocking Pushing your Pi beyond stock frequencies significantly increases power consumption and heat generation. Overclocked Pi 5 models can see power draw increase by 20-40% over standard settings. Operating System and Software Different operating systems and background services impact power usage: Lightweight distributions like Raspberry Pi OS Lite consume less power than full desktop environments Background services, automatic updates, and constant logging increase power draw Power management settings can significantly affect consumption patterns External Storage Storage devices can be surprising power consumers: USB flash drives: 0.2-0.5W Powered external HDDs: 2.0-5.0W SSDs: 1.0-3.0W depending on activity Real-World Power Consumption Examples To put these numbers in context, here are some typical usage scenarios: Headless server (Pi 4, no display, running web services): ~3.5W average Desktop replacement (Pi 5 with display, keyboard, mouse, running desktop environment): ~7.5W average Media player (Pi 4 streaming video to HDMI display): ~6.0W average Weather station (Pi Zero 2 W with sensors, running on batteries): ~1.0W average Home automation hub (Pi 4 with various USB devices): ~5.0W average Choosing the Right Power Supply Selecting an appropriate power supply is critical for stable operation: Raspberry Pi 5: Official recommendation is 5V/5A (25W) USB-C power supply Raspberry Pi 4: Requires 5V/3A (15W) USB-C power supply Raspberry Pi 3 B+: Works well with 5V/2.5A (12.5W) micro-USB supply Pi Zero models: Can operate reliably with 5V/1.2A (6W) micro-USB supply Using underpowered supplies often leads to subtle but frustrating issues: Random reboots and crashes SD card corruption The dreaded "rainbow square" power warning Peripherals failing unpredictably Tips for Optimizing Raspberry Pi Power Efficiency When every milliwatt matters, consider these optimization strategies: Underclock the CPU when maximum performance isn't needed Disable unused interfaces with commands like: sudo rfkill block wifi # Disable Wi-Fi sudo rfkill block bluetooth # Disable Bluetooth tvservice -o # Disable HDMI output Use lightweight operating systems like Raspberry Pi OS Lite or DietPi Optimize software by removing unnecessary services and scheduling resource-intensive tasks Implement power management tools like PowerTOP or TLP where available Choose power-efficient peripherals and disconnect unused devices Consider a lower-power Pi model for tasks that don't require maximum performance Conclusion Understanding your Raspberry Pi's power consumption is essential for designing reliable and efficient projects. From the ultra-efficient Pi Zero W at under 1W to the powerful Pi 5 that can draw up to 9W under load, each model offers a different balance of performance and power efficiency. By selecting the appropriate model for your needs, pairing it with the right power supply, and implementing proper power optimization techniques, you can ensure your Raspberry Pi projects run reliably whether they're powered from the wall or operating on batteries in the field. Remember that real-world power consumption varies based on your specific configuration and workload, so consider measuring the actual draw of your completed project using a USB power meter for the most accurate assessment.

Why India’s Drone Industry Needs Periplex: The Hardware Tool Drones Didn’t Know They Needed

As drones fly deeper into critical roles — from agricultural intelligence to autonomous mapping, from disaster response to military ops — the hardware stack that powers them is undergoing a silent revolution.

At the center of that transformation is Periplex — a breakthrough tool from Vicharak’s Vaaman platform that redefines how drone builders can interface with the real world.

What is Periplex?

Periplex is a hardware-generation engine. It converts JSON descriptions like this:{ "uart": [ { "id": 0, "TX": "GPIOT_RXP28", "RX": "GPIOT_RXN28" } ], "i2c": [ { "id": 3, "SCL": "GPIOT_RXP27", "SDA": "GPIOT_RXP24" }, { "id": 4, "SCL": "GPIOL_63", "SDA": "GPIOT_RXN24" } ], "gpio": [], "pwm": [], "ws": [], "spi": [], "onewire": [], "can": [], "i2s": [] }

…into live hardware interfaces, directly embedded into Vaaman’s FPGA fabric. It auto-generates the FPGA logic, maps it to kernel-level drivers, and exposes them to Linux.

Think of it as the “React.js of peripherals” — make a change, and the hardware updates.

Real Drone Applications That Truly Need Periplex

Let’s break this down with actual field-grade drone use cases where traditional microcontrollers choke, and Periplex thrives.

1. Multi-Peripheral High-Speed Data Collection for Precision Agriculture

Scenario: A drone is scanning fields for crop health with:

2 multispectral cameras (I2C/SPI)

GPS + RTK module (2x UART)

Wind sensor (I2C)

Sprayer flow monitor (PWM feedback loop)

ESCs for 8 motors (PWM)

1 CAN-based fertilizer module

The Periplex Edge: Microcontrollers would require multiple chips or muxing tricks, causing delays and bottlenecks. With Periplex:

You just declare all interfaces in a JSON file.

It builds the required logic and exposes /dev/pwm0, /dev/can0, etc.

Zero code, zero hassle, zero hardware redesign.

2. Swarm Communication and Custom Protocol Stacks

Scenario: Swarm drones communicate over:

RF LoRa (custom SPI/UART)

UWB mesh (proprietary protocol)

Redundant backup over CAN

Periplex lets you:

Create hybrid protocol stacks

Embed real-time hardware timers, parity logic, and custom UART framing — none of which are feasible in most MCUs

Replacing Microcontrollers, Not Just Augmenting Them

| Feature | Microcontroller | Periplex on Vaaman | |---------------------------|----------------------------|------------------------------------| | Number of peripherals | Limited (4–6) | Virtually unlimited (30+ possible) | | Reconfiguration time | Flash + reboot | Real-time, dynamic reload | | Timing precision | Software-timer limited | FPGA-grade nanosecond-level timing | | AI compatibility | Not feasible | Integrated (Gati Engine) | | Sensor fusion performance | Bottlenecked | Parallel FPGA pipelines |

Developers Love JSON, Not Register Maps

No more:

Scouring 400-page datasheets

Bitmasking registers for I2C configs

Writing interrupt handlers from scratch

Just declare what you need. Let Periplex do the work. Peripherals become software-defined, but hardware-implemented.

Built in India, for India’s Drone Revolution

Vaaman + Periplex isn’t just about tech. It’s about self-reliance.

India’s defence, agriculture, and logistics sectors need secure, reconfigurable, audit-friendly hardware — not black-box SoCs from questionable supply chains.

Periplex is the hardware engine for Atmanirbhar Bharat in drones.

TL;DR

Periplex lets drones adapt hardware to the mission — instantly.

It replaces tangled microcontroller logic with clean, structured JSON.

It unlocks use cases microcontrollers can’t touch: AI at the edge, dynamic reconfiguration, secure protocol stacks, and more.

And it’s built into Vaaman, India’s first reconfigurable edge computer.

Rasping

I maintain and publish a couple open-source libraries that are cross-compiled for 32-bit Linux-on-ARM platforms such as the Raspberry Pi. I think it's important to test the code I publish. Unfortunately, my test machine (a Pi 400) can't execute those binaries because its operating system is too old: in particular, its "stdc++" library isn't recent enough.

A colleague in Cairo, Egypt told me various ways to upgrade the library by installing a newer compiler on the Pi. I tried them last night without success.

My current plan is to install a newer version of the operating system. This involves downloading a disk image and writing it to the Pi's MicroSD card. To do that, I need a USB-MicroSD adapter for my HP laptop. They cost about $10 or $20 online, but I'd rather not wait for shipping. So I'm running out to Staples this morning to buy an adapter.
