堆肥の温度記録: 固定した計測点、固定した深さ、山のそばの気温、そして切り返しごとのイベント記録
庭の堆肥の山やビンを対象とした観察プロトコルの提案: 長い軸を持つ温度計を使い、印を付けた計測点と定めた深さで決まったスケジュールに沿って測定し、同じ瞬間に山のそばの気温も記録し、材料の追加・切り返し・水やりはすべてイベント行としてログに残す。これにより、山の温度の上昇・停滞・低下を、山に対して行われた作業と突き合わせて読み取れるようにする。目標温度や成果については何も主張しない。

家庭用温度計の氷水浴での示度を記録する: 器具ごとのオフセット記録
NISTによる氷の融点の説明(蒸留水から作った砕いた氷、上から下まで氷と水が混ざった状態、定めた浸漬深さ)に従い、家庭にある各温度計が名目上0℃で何を示すかを、日付・準備の詳細・示度が安定するまでの時間とともに記録するだけのプロトコル案。器具ごとのオフセットの履歴を残すものであり、調整方法や食品用途についての指針は与えない。

2つの家庭が結果を比較できるように、家庭での種子発芽比較はどう設計すべきか
未解決の問い: 検査機関はISTAのInternational Rules for Seed Testingに基づいて種子を検査するが、2つの種子ロットや2つの窓辺を比較する家庭には共通のプロトコルがない。どのようなサンプルサイズ、カウントルール、期間、条件の記録があれば、こうした家庭での比較は有益になり、家庭間でも比較可能になるのか。

Which household records fix the start and end of a power outage after the fact, and how far have they disagreed?
Open question: after a power cut a household has several clocks of the event, such as the utility's notice, a UPS log, a router's uptime, a home server's reboot records (the last(1) manual page states that last reboot produces a record of reboot times, and journalctl can list boots with the timestamps of each boot's first and last message), a battery clock that kept time and a mains clock that flashes; which of these have households actually used, how far did they disagree, and which gave the earliest and latest bounds?

自宅の蔵書や工具を棚卸しする：識別子、保管場所、確認周期
蔵書や工具の家庭内在庫を単純な表で管理する。各品物の安定した識別子（本はISBN、工具は自分で付けるコード）、凡例付きの場所コード、固定語彙による状態、貸出欄、そして見つからない物を削除せず記録する定期巡回を使う。評価額や保険の助言は行わない。

A grocery price log with the unit price computed from the pack: barcode identity, pack quantity, shelf price and promotion flag per observation
A proposed record-only protocol for logging grocery prices in which each observation carries the product's barcode number as its identity, the pack quantity as printed, the shelf price and any promotion or loyalty condition, and a unit price computed by the household in a stated unit, following the definition in EU Directive 98/6/EC of the unit price as the final price per kilogramme, litre, metre, square metre or cubic metre; a changed pack size becomes a new product row, and no purchasing advice or inflation figure is given.

Household log entries written from memory at the end of the day show more rounded values than entries written at the moment of reading
Hypothesis: when a meter, scale or thermometer reading is written down hours later from memory, the recorded value is more often a round number (ending in 0 or 5, or with fewer decimals) than when it is written at the instrument; a proposed within-household test with alternating days and photographs as the reference, with no claim about which value is closer to the truth.

Checking a kitchen scale with coins of published mass: a repeatability, range and corner-load record
A proposed record-only protocol for a household scale: use new coins whose nominal mass the issuing mint publishes as reference masses, log readings for single coins and stacks across the scale's range, repeat placements, test the four corners and a timed hold, and keep the sheet per scale; no adjustment and no pass or fail judgement is part of it.

A watering and growth log for houseplants: fixed measurement points and photographs
A proposed observation log for potted plants: measurement points defined once (height from the pot rim, leaf count above a stated size, largest leaf length), watering recorded by volume or mass, position and events, and a weekly photograph under the same conditions, so that growth can be compared over time and between plants; no care advice is given.

Two consumer hygrometers in one room disagree less on dew point than on relative humidity
Hypothesis: two consumer temperature-humidity devices placed at different spots in one room report relative humidity values that differ mainly because their temperatures differ, so the dew points computed from each device's own pair agree more closely than the raw RH readings once the fixed inter-device offset is removed; no measurement is reported.

家庭のインターネット速度を再現可能に測る：経路と時間帯を固定する手順
家庭のスループットと遅延を連続記録する提案手順です。端末、有線または無線の経路、ツール、サーバーを固定し、2週間、毎日3つの決まった時間帯に3回ずつ連続テストし、接続数と家庭内の活動を記録します。RFC 6349の帯域幅遅延積と単一・複数接続の論点は、ツール設定で数値が変わる理由として読みます。特定の事業者については何も主張しません。

An expense categorisation log as a method: frozen category list, numbered edge-case rules and a re-coding check
A proposed documentation method for household spending records: freeze a category list with definitions before coding, keep one row per transaction with amount, currency, payee as printed and a rule identifier, turn every edge-case decision into a numbered rule, and re-code a blind sample monthly to measure self-agreement; it produces interpretable category totals and gives no financial advice.

A heating-season log: heating input, indoor temperature and degree days on one timeline
A proposed protocol for one heating season: read the household's heating input (a heat, gas or electricity meter or thermostat runtime) at a fixed time, log indoor temperature and setpoint changes beside it, derive heating degree days from logged daily highs and lows with a stated base, and keep a conditions column so that a month's consumption can be checked against weather and events; no target temperature or saving is asserted.

家庭の電力メーターを決まった時刻に読む：観察手順

How comparable are phone light-meter app readings of indoor plant positions between phones and apps?
Open question: phone apps report illuminance in lux for a windowsill or shelf, reading either the ambient light sensor that Android documents most manufacturers use to control screen brightness, or an estimate from the camera; what is known about agreement between two phones at the same spot and time, the effect of orientation and screen glass, and which logging conventions would let two households compare plant positions?

Logging a consumer PM2.5 sensor: what to record beside each reading and what the number cannot say
A consumer particulate sensor reports an estimate of the mass of particles 2.5 micrometres and smaller; the EPA states that such sensors come with lower accuracy and higher uncertainty than regulatory monitors, describes collocation with reference instruments as an effective way to assess them, and notes that an outdoor correction may not apply indoors and that changing temperature and humidity may affect some sensors. A household log therefore stores the raw value, the averaging interval, placement, indoor events and the nearest official monitor's value with its distance.

A home weather diary: what a garden or balcony sensor records and why it differs from the official station
A home weather diary is only comparable with other records when the sensor's exposure is written down: the Met Office measures air temperature in a naturally ventilated Stevenson screen 1.25 m above the ground, while a sensor on a wall, under an eave or in sunlight measures its own surroundings; the article describes the diary columns, the exposure description and the home-minus-station difference series.

A houseplant leaf-condition and pest-sighting log with tagged leaves and fixed photographs
A proposed observation protocol for houseplants: tag three leaves per plant, photograph upper and lower surfaces weekly against the same background, record spots, edge condition, residue, webbing and counted visible insects in a fixed vocabulary, count dropped leaves between visits, and keep identification attempts separate from the observations; no treatment is stated.

Mass versus volume in cooking: which cup is meant, and how to record the conversion actually used
A cup, tablespoon or teaspoon is a volume whose definition differs between the US customary units listed by NIST and the rounded values used on US nutrition labels, and the mass it holds depends on the ingredient and how it was filled; a household that converts between mass and volume records the definition it used and its own weighed values so that a recipe can be reproduced.

A parcel delivery time log: order, dispatch, tracking and door timestamps on one row, with the carrier's scan and the observed arrival kept apart
A proposed record-only protocol for logging each parcel's timeline as timestamps in the RFC 3339 Internet Date/Time Format with UTC offsets, taken from the order confirmation, the dispatch notice, the carrier's tracking events and the household's own note of the arrival, with the carrier, service, delivery place and each attempt recorded; the carrier's delivered scan and the observed arrival are separate columns, and no carrier comparison or delivery-time claim is made.
