Building technology that heals, connects, and remembers. I work at the meeting point of artificial intelligence, hardware, and the human body — and I build in the open, for real people.
Building in the open
I'm Iddo Perez — a hands-on builder working at the meeting point of artificial intelligence, hardware, and the human body. I design and ship end-to-end: from soldering boards and writing firmware to training models and wiring up AI agents. I work with AI (Claude, Grok, local models) as everyday collaborators, and I build in the open.
My projects span bio-signal games you play with your muscles and brainwaves, off-grid mesh radios, AI you can build yourself, smarter agriculture, and tools for healing. I care about making powerful technology approachable — turning it into things real people can hold, use, and learn from.
Much of what I make is dedicated to the people I carry with me — above all my sister, Alma ז״ל, whose memory this site holds. I believe technology, at its best, is a way to keep love and knowledge alive and free.
Open-source builds, free books, and bio-neurotech — all real, most downloadable right here.
פונג שמנגנים עם השרירים, הלב והמוח.
Play Pong with your muscles (EMG), heartbeat (ECG), or brain/eye signals (EEG) on an Arduino + AD8232. Modes: vs-Bot, vs-Claude-AI, 2-player, multi-trainee — with auto-calibration, sound, an eyes-closed audio mode, and a VR version in Godot with haptics.
Downloadableלהפוך את פעימות הלב או השרירים למוזיקה רגועה ויפה.
Turns your heartbeat (ECG) or muscles (EMG) into calm, always-in-key generative music — as live MIDI into Ableton, or as standalone ambient audio with no DAW at all. Every beat blooms a note; a held flex opens the timbre into a swell.
Runnableמקלדת מתג-אחד בעברית ואנגלית שמדברת בקול — לאנשים שאינם יכולים להקליד.
A one-switch Hebrew + English keyboard for people who can't use a normal keyboard (ALS, paralysis, locked-in). One muscle signal drives clinical-standard scanning with word prediction, and the message is spoken aloud in a natural Hebrew or English voice.
In testingרייב-מייקר על בסיס שרירים — הגוף שלך מבצע את הדרופ.
A bio-muscle EDM "ravemaker" built on a from-scratch numpy synthesis + arrangement engine: your muscle flex drives the build-up and performs the drop. Anthem / progressive-house and melodic-oriental flavours, rendered live or to a track.
Runnableיועץ השקעות מבוסס AI — נייר תחילה, אתה מחליט.
An AI investing/finance advisor that studies market cycles and the great investors' playbooks and recommends — it never moves money. Paper-trading first: every call comes with a probability, expected value, and max-drawdown. Iddo authorizes every real trade himself.
Paper-tradingמחקר במחשוב ביולוגי/עצבי — חיים שמחשבים.
Research into biological and neural computing ("wetware" / organoid intelligence) — including a brief on Prof. Oded Shoseyov's plant-made human collagen and its role as a leading 3D-bioprinting bioink. Living substrates and gentle bio-interfaces, studied honestly.
ResearchA multi-channel messaging-orchestration app: run campaigns across WhatsApp, email, SMS, MQTT, and Telegram from one place, each channel a pluggable connector with built-in per-recipient rate limiting so it never floods anyone.
Open sourceA real-time, fully local guitar lesson companion that listens to you play and teaches back — pitch, onset, and chord detection under 70 ms, no cloud, no subscription. Calm and honest: it tells you when the string is sharp.
RunnableA dating-app concept designed to be deleted: success is the user finding a real partner and leaving happy. No infinite swipe, no paywalled likes, no dark patterns — curated daily matches and a nudge toward the real world. Hebrew-first.
ConceptA friendly guide to building your own AI from the ground up — from concepts to running models. Free, in English and Hebrew.
Free PDFSmart, sustainable farming — vertical & hydroponics, desert smart-farms, compost science, and sensors. Free PDF.
Free PDFAI לילדים ולנוער — דרך קומיקס.
AI explained for young people through comics & stories — neurons, weights, transformers, and attention, told Marvel-style.
In progressBuild the fundamentals yourself — a neural net and calculator from first principles, no black boxes. Open source.
Open sourceInfrastructure-free, encrypted messaging over LoRa radio (Heltec 915 MHz) — multi-hop mesh, kilometres of range, no internet. Open source.
Open sourceA system where Claude, Grok, and local models collaborate on real work over a shared file / MQTT bus. Open, inspectable, self-hosted.
Self-hostedAn AI-assisted Arduino / ESP board doctor: detects the board, diagnoses driver / port / bootloader problems, and flashes a test sketch — with a local-AI explanation layer that works offline via Ollama.
DownloadableDual-role Bluetooth audio on ESP32 — receive and retransmit simultaneously — in raw ESP-IDF. Open-source firmware.
Open sourceמחשוב מאגר על בסיס תרבית חיה.
An experiment in reservoir computing using living substrates (SCOBY / "fakir-kombucha") as a physical neural network — teaching a living culture to play Pong.
ResearchA personal AI assistant on WhatsApp, running on free local models — your own private secretary that never sends your data to the cloud.
Self-hostedFree bilateral-stimulation tools and a curated library for EMDR-style self-regulation. Educational — not a substitute for a licensed therapist.
Live siteThe bio-signal and AI work that needs a couple more lines of plain language.
Bio-Music maps each heartbeat to a note, the inter-beat interval to tempo, and heart-rate variability to gentle dynamic "breathing" — everything is scale-quantized, so it can never play a wrong note. EMG (muscle) mode makes a sustained flex an evolving swell. It sends MIDI into Ableton or voices itself with lush ambient reverb, no DAW required.
BioRave is the same body-as-instrument idea turned up: a from-scratch numpy EDM engine (kick, supersaw, reese bass, sidechain pump, full build/drop arrangement) where your muscle flex performs the drop. Avicii-flavoured anthem house and DJ-Darwish melodic-oriental moods.
For people who cannot use an ordinary keyboard — ALS, paralysis, cerebral palsy, locked-in syndrome — BioKeyboard turns one reliable movement (a jaw clench, a forearm flex, a blink) into a switch, then uses the clinical AAC standard of one-switch automatic scanning to reach the whole keyboard. Word and letter prediction keep it humane and fast.
It writes full Hebrew (RTL, with automatic final-letter forms) and English, and speaks the message aloud in a natural per-language voice — or types it straight into WhatsApp or email. A short tap selects, a long hold deletes, a double-tap speaks. It is assistive technology, not a medical device.
Kesef is an AI investment advisor that learns the markets, synthesizes economic cycles (Kondratiev / Juglar / Kitchin / seasonality / Fed-rate) and the great investors' playbooks, and recommends — it never moves money. It runs paper-first (DRY), and every call is a probability + expected value + max-drawdown with the playbooks behind it. It never calls a trade "safe"; Iddo authorizes every real trade personally.
An ongoing research thread into biological and neural computing — "wetware", organoid intelligence, and gentle, safe bio-interfaces. It includes an honest, web-sourced brief on Prof. Oded Shoseyov's plant-made recombinant human collagen, the basis of a leading 3D-bioprinting bioink (kept carefully separate from Prof. Tal Dvir's 2019 3D-printed heart).
