   The whole StudyOne

   The desk lamp is the study desk's own helper: a page camera, a mic, an eye-distance sensor and a light sensor inside the lamp head feed one brain that checks sums and spelling, follows reading aloud, calls breaks and eye distance, shows each call on the lamp with a voice, and sends the parent one summary.

2. 02Brain

   Raspberry Pi Zero 2 W (in the lamp head)

   The brain: it runs the studyone-fw program

3. 

   03

   Page camera

   Reads the sums and spelling on the page, the page being read aloud, and a lit phone or tablet on the desk

   Raspberry Pi Zero 2 W (in the lamp head) · CSI-2 ribbon · Page frames, 2 a second while working

4. 04

   Reading mic

   Hears the child read aloud and spell words; speech stays on the lamp

   Raspberry Pi Zero 2 W (in the lamp head) · I²S · Audio, 16 kHz

5. 05

   Eye-distance sensor

   Measures the head's distance from the lamp: too close to the page, sat down, left the desk

   Raspberry Pi Zero 2 W (in the lamp head) · I²C · Distance, 10 times a second

6. 06

   Page light sensor

   Measures the light on the page so the lamp holds about 500 lux

   Raspberry Pi Zero 2 W (in the lamp head) · I²C · Lux

7. 07

   Reading light, call light and voice

   The reading light, plus each call on the lamp: green tick, amber 'look again', blue break; the voice reads words and hints through the base speaker

   Raspberry Pi Zero 2 W (in the lamp head) · One data wire + I²S · Light colour and voice

8. 08

   Secure element and tamper switch

   Signs each call and the evening summary; marks the log and locks the camera if the head cover is opened

   Raspberry Pi Zero 2 W (in the lamp head) · I²C + GPIO · Signatures, tamper flag

   7 key parts, one program, and your phone

Our circuit board · rev A-0

One board of our own inside StudyOne

Every chip on one board we design, shaped to fit: the processor, cameras and sensors, Wi-Fi and Bluetooth, lights, sound and power. No plugs, ribbons or adapters. It is checked in our CAD against every part around it, and it arrives from the maker ready to run our software from a microSD card. Turn the model, or pick a part below to see where it sits.

The idea

The desk lamp over a child's homework checks the sums, listens to the reading, calls the breaks and minds the eyes, then tells the parent

Pricing

Target pricing (stage 2, raised from $229 so a first batch is not sold below cost). Bought separately, an eye-care study lamp (about $249, est.), a posture trainer (about $80, est.), a focus timer (about $15, est.), a homework app (Photomath Plus $9.99 a month) and a reading app (Ello $14.99 a month) add up to about $344 + $25/month. Parts cost about $188 per lamp at qty 1 including the lamp body (prices checked 28 Oct 2026; lamp body est.).

Indicative launch pricing in USD, excluding taxes and shipping. Final pricing is confirmed before any balance is charged.

1. 4 Nov 2026, 00:46LatestA parent buys StudyOne as the child's desk lamp, so its electronics must be one board an assembly house makes and tests the same way, with nothing plugged together inside the lamp, only 5 V in a child's luminaire (IEC 60598-2-10), a reading light that is safe for a child's eyes (IEC 62471), and enough camera detail to read a child's handwritten answer at the far corner of the page.

   • What we designed: one rigid-flex board inside the desk lamp. An 8-layer head board, 358 by 50 mm, lies flat in the hollow steel head arm 12 mm over the opal cover. Underneath, an 8-megapixel camera chip under a small lens looks straight down at the page; sixteen white LEDs (4000 K, high colour quality, no flicker) are the reading light and eight colour LEDs the call light; a light chip under a short light pipe reads the page light; the mic sits over a new port in the cover; the tamper switch and the latched microSD card sit there too. On top, the RV1126B presses a small aluminium block into the steel arm, which is its heat sink, with the memory, Wi-Fi, security chip and the camera's supplies. At the front end a 12 by 12 mm tab is cut free on a 2 mm hinge and folded 45 degrees down, so the eye-distance chip looks at the child's head. An 18 mm flex runs about half a metre down the column to an 80 by 60 mm base board with the USB-C power inlet, its protection and the speaker amp. It replaces the Pi Zero 2 W, the Camera Module 3 on its ribbon, the mic, distance, light, security and amp boards and three LED sticks. See /build/studyone-boards
   • How we checked it: the board is written as code and opened in KiCad (0 design-rule violations). It places 60 parts at their datasheet sizes and checks that each sits on its board with no overlaps, clear of the tab's slot, with heights that fit every gap; that the camera, reading and call lights, light chip, mic and tamper switch sit on their windows in the lamp design; that all seven camera calls in the lamp design (four page corners, a phone either side of the book, the pencil at the near edge) are in view, the worst at 33.4 degrees against 45; that the folded tab's axis meets the eye window exactly and both too-close calls are inside its cone (4.3 and 10.2 degrees against 13.5); that the boards clear the arm, the column and the speaker; and that the USB-C sits in the back inlet. Design review with the shared rules: 15 pass, 2 fixed, 7 to prove, 0 fail. A 3D model shows it in a see-through lamp or laid flat, and the quote pack and design files are on the board page
   • What we learned: a 4 mm handwritten digit at the far page corner fills about 20 pixels on the 8 MP chip with a 90 degree lens, against the 15 the reading model needs (est.), at 5 frames a second and 12 % of the camera link. With the camera chip on the board under a lens holder, the camera window must grow from 14 to 17 mm, and the eye window from 8 by 10 to 11 by 12 mm for the folded tab: both changes go into the lamp design. The steel arm makes a good heat sink, but its touch temperature with the reading light at full is measured on rev A. About $98 a lamp in electronics at 1,000 (est.), about $32 less than the bench boards
   • What is next: the camera chip and lens holder from their makers' drawings; the board placed in the lamp CAD with every part checked in 3D and the five lamp changes (two bigger windows, a mic port, a tamper boss, the ballast moved forward); and the next product's board, DockOne

2. 29 Oct 2026, 22:55Parents want homework help at the desk without a camera sending their child's day to the cloud. The FTC's updated children's privacy rule (COPPA) has applied in full since 22 April 2026: a separate parent consent before a child's data goes to anyone else, a written limit on how long data is kept, and voiceprints and face templates now count as a child's personal data (FTC, 16 CFR 312).

   • Market and rules check (DESIGN.md): the amended COPPA Rule in force from April 2026, the EU AI Act ban on emotion recognition in schools and the 2026 delay of its high-risk education rules to December 2027, and new camera homework lamps and projector buddies, each with what it changes in StudyOne (sources K1-K8)
   • Privacy: the optional cloud homework help now has its own second consent; a written retention policy (unsure-answer photos 7 days, call log and summaries 12 months, est.); no voice enrolment and no face template; the focus timer never reads faces or feelings
   • Rules: two new rule lines in equipment.json (COPPA as amended in 2025 and the EU AI Act); no CAD change and no new part
   • Market: 6AM's Vicam camera lamps stream the desk to parents, who still do the checking; no competitor found marks the page on the device. Price kept at $279 + $4/mo
   • Product page https://iemilabs.com/products/studyone/ gains a 2026 privacy and AI rules FAQ and a clearer child's data spec
   • Next: ask parents in the phase 3 buyer review whether the second consent is clear and whether 7 days for photos is right; close-out C9 (recommend the first product to the owner) from 30 Oct 00:00

   See it in 3DFull research and design

3. 29 Oct 2026, 13:25Before customer reviews start in phase 3, StudyOne and ClassOne need a list of who to ask, their three open questions and a short survey, plus the child-safety and privacy questions every parent and school will ask. This is close-out task C7 in our phase 1 plan.

   • Section "Kids learning" in products/BUYER-REVIEW.md: StudyOne and ClassOne each get who to ask (parents, tutoring centres and a teacher for StudyOne; heads, a trust IT lead, teachers, the data protection lead and a governor for ClassOne, with sources), the three open questions from their stage 2 refinement, a five-question survey and what each answer would change
   • Extra rules for kids reviews: we never speak to a child alone or ask a child to fill in a survey, never film or photograph a child, a homework page or a classroom, ask nothing about results, needs or health, and never suggest the products keep a child safe
   • Four child-safety and privacy questions asked in every kids review: the camera, what leaves the device, who must agree before it is switched on, and how long records are kept, based on the US and UK children's privacy rules and school records law
   • What we learned: for both products the camera is the purchase decision, not a feature, so a camera-off first version is ready as an answer; buyers may also want one job first, and whether to pay once or monthly is still open
   • Next: close-out C8, the same review prep for the eleven industry products

   See it in 3DFull research and design

4. 29 Oct 2026, 06:25Before customer reviews, each of the 24 stage 2 products should have its own buyer and its own place, so no customer is asked to buy two products for one job, and the places we do not cover yet should be written down with the reason. This is close-out task C2 in our phase 1 plan.

   • New section "Overlaps and gaps" in products/LINE-REVIEW.md: six look-alike pairs compared on buyer, place, item, calls and price, with sources from each product's buyer check
   • What we learned: no two products share a buyer and a place, so none is folded. StudyOne (a parent, one child's desk lamp) and ClassOne (a school, the classroom whiteboard); BedsideOne (a family, a parent living alone) and CareOne (a care home or ward); DampOne (a home bathroom fan) and RoomOne (a hotel room thermostat) each answer a different buyer
   • Each of those six product pages now has a FAQ saying who the other product is for
   • Where two products use the same sensor for the same call (bed exit in BedsideOne and CareOne), phase 3 can test that call once for both
   • One label fixed: AthleticsOne was filed as "School athletics and swimming" but none of its calls covers a pool; it is now "School athletics" and swimming is a listed gap
   • Places with no product yet, each with the reason: rugby and hockey, volleyball and badminton, swimming, golf, children's bedrooms and living rooms, offices, airfields, forklifts, vehicles and gyms
   • Four older catalogue products stay listed beside a flagship because they do a job it does not claim: GasLock LPG (exact cylinder refill), DampHome and PureTrack (the water purifier), WaterLeak AI (the building riser and main valve)
   • Next: close-out C3, one pricing table for all 24 products with BOM cost, margin and what the buyer pays today

5. 28 Oct 2026, 23:20A parent of a child aged about 6 to 12 needs homework checked, reading aloud heard, breaks and eye distance called and good light on the page, often while still at work: today that is an eye-care study lamp (BenQ MindDuo 2 Plus about $250), a homework app (Photomath Plus $9.99 a month) and a reading coach (Ello $14.99 a month), with a phone held over the page.

   • Buyer check with sources: what parents pay today for an eye-care study lamp (BenQ MindDuo 2 and 2 Plus), a homework app (Photomath Plus) and a reading-aloud coach (Ello), and the three closest products
   • What we learned: Ello already listens to children read aloud on a tablet, so the apps cost about $25 a month, not $22; camera lamps sold well in China, and our edge stays that no video or voice leaves the lamp
   • Price raised from $229 to $279 + $4 a month (at $229 a first batch made about 6 %); still under a study lamp plus a reading app for a year
   • Reading light fixed: the two RGB light sticks made white by mixing colours, weak and poor on the page; they are now RGBW sticks with their own white LED, on the same size board (Adafruit page checked), so the CAD fit is unchanged
   • Parts list prices checked on shop pages today: $188 of parts per lamp at qty 1; cost and margin table in the design notes (about 23 % at qty 1 and 45 % at qty 100, est.)
   • Product page: the first three FAQs answer the buyer's top questions (why not a study lamp and a homework app, is there a camera on my child, what it costs)
   • Next: three questions for parents in customer reviews (price, the camera, which job matters most), then ClassOne for the classroom

6. 28 Oct 2026, 07:25A parent of a school-age child needs one thing on the desk that checks homework without giving answers, listens to reading, calls breaks and minds the eyes, without sending photos of the child to the cloud. Camera study lamps already sell (ByteDance Dali lamp, TechCrunch) and eye-care lamps sell at about $249 (BenQ MindDuo 2), but the camera lamps sent photos of children to parents.

   • New CAD: the bar desk lamp (200 x 160 base, 400 mm head arm at 450-480 mm), head cover and base plate, with the brain, page camera, mic, eye-distance and light sensors, reading and call lights, secure element and tamper switch in the head, speaker and amp in the base; 12/12 parts fit from datasheets, 10 sensor views checked, tilt check passes, no collisions, no floating parts
   • equipment.json: children's luminaire (IEC 60598-2-10), stability, blue light, COPPA and GDPR-K rules, 8 calls (6 alone), 3 impact cases and every security key
   • idea.json desk plan, integration.json (6 parts, 5 app screens with Parent at work mode), BOM, buy.json and DESIGN.md with the market check
   • Product page at $229 + $4/month against about $344 + $22/month bought separately (est.); no IEMI product folded: IEMI Gecko stays the classroom robot kit
