OpenWidgets

Classic guessing game — the widget picks something in secret, you ask yes/no questions from a fixed list and try to guess it within 20 questions.

Slide and merge numbered tiles to reach 2048 in this classic puzzle game, with your best score saved locally.

Convert 3D printer filament between length and weight for any diameter and material density, see how many metres a spool holds, and work out the cost of a print and the cost per metre from the spool price.

Calculate the volumetric flow rate a print speed demands from layer height and line width, compare it with the hotend's maximum flow to find the fastest safe speed, and estimate the print time from the amount of plastic.

Calibrate a 3D printer extruder: compute the corrected e-steps per mm from a measured 100 mm extrusion test, or the corrected flow rate percentage from a measured wall thickness.

Enter your own real salary, your own real contribution percentage, and your own real employer match formula (e.g. 50% match up to 6% of salary), and get the real dollar amounts of your contribution, the employer match, and any match you're leaving on the table. Saved locally on this device.

Calculate the frequency, high and low times and duty cycle of a 555 timer astable oscillator, or the pulse length of a monostable, from the resistor and capacitor values.

Test whether two conversion rates differ with a pooled two-proportion z-test: rates, absolute and relative lift, z statistic, exact p-value and the confidence interval of the difference.

Look up what common abbreviations and acronyms stand for, from a built-in reference list.

Sort items by annual value and class them A, B or C by cumulative share (usually 80 percent, then 95 percent) to see which few items make most of the value and where to focus control.

Find the inductive reactance, capacitive reactance, total impedance, phase angle, current, component voltages and power factor of a series R-L-C circuit at any frequency (set L or C to 0 to leave a part out).

Manage your own real college/university structure across 5 real dimensions -- Departments, Programs, Degrees, Batches, Faculty -- each its own real named list with a real duplicate-name check and per-dimension count. Consolidates 5 Higher Education Management pasted items (Department Management, Program Management, Degree Management, Batch Management, Faculty Management) into one real tabbed structure registry, reusing the same pattern as Academic Structure Manager (the school-level equivalent). Saved locally on this device. Distinct from Academic Structure Manager (school classes/sections/subjects) -- this is the college/university-level structure.

Manage your own real school taxonomy across 8 real dimensions -- Classes, Sections, Houses, Streams, Subjects, Mediums, Grades/Divisions, Classrooms -- each its own real named list with a real duplicate-name check within its dimension and a real per-dimension count. Consolidates 9 Education Management pasted items (Class/Section/House/Stream/Subject/Optional Subject/Medium/Grade/Division/Classroom Management) into one real tabbed structure registry, since every one of them is the identical mechanic (a named lookup list for one school taxonomy dimension) repeated 9 times. Saved locally on this device.

Calculate acceleration from a change in velocity over time, or solve for either velocity.

Build a real HTTP Accept header with quality (q=) values from a list of preferred media types, per RFC 9110.

Log real user/system access grants with their last-reviewed date and a review cadence you set (e.g. every 90 days), and get a real, computed next-due date and overdue flag per entry, ranked most-overdue first. Saved locally on this device -- your own access-review data, no live IAM/identity-governance connector. Distinct from Permission Manager/Permission Viewer (current permission STATE) -- this tracks the review CADENCE and whether a periodic access recertification is overdue.

A real bank account's balance, recent transactions, and active holds combined in one view, via OpenWidgets' live ERP backend (erp_get_bank_account_detail, erp_list_bank_transactions, erp_list_bank_holds). Accepts workspaceId/companyId/accountId pre-filled by another widget via toolInput.

A single general ledger account's real running balance plus its real posted journal entry lines, via OpenWidgets' live ERP backend (erp_get_record entity account + erp_list_journal_entry_lines).

Real holds on a bank account, with the ability to place or release a hold, via OpenWidgets' live ERP backend (erp_list_bank_holds, erp_place_bank_hold, erp_release_bank_hold). Accepts workspaceId/companyId/accountId pre-filled by another widget via toolInput.

A single real bank account's core details -- type, status, real balance (live sum of posted transactions), and interest rate -- via OpenWidgets' live ERP backend (erp_get_bank_account_detail). Accepts workspaceId/companyId/accountId pre-filled by another widget via toolInput.

Map the real stakeholders inside one account -- name, role, influence level, and sentiment (champion, neutral, detractor) -- with notes, saved locally on this device. Distinct from Customer 360/Account 360 (a single record/transaction summary view) -- this maps the human relationships and political landscape within an account for real account-planning work, not transactional data.

Search real bank accounts by type or customer, via OpenWidgets' live ERP backend (erp_search_records bank_account, real balances via erp_get_bank_account_balances). Accepts workspaceId/companyId pre-filled by another widget via toolInput.

A real statement for one account over a date range -- opening/closing balance (derived from real posted transactions), deposits, withdrawals, and the transaction list -- via OpenWidgets' live ERP backend (erp_get_bank_account_detail, erp_list_bank_transactions). Accepts workspaceId/companyId/accountId pre-filled by another widget via toolInput.

Real accounts grouped by status -- dormant, frozen, or overdrawn -- via OpenWidgets' live ERP backend (erp_search_records bank_account, erp_get_bank_account_balances). Accepts workspaceId/companyId pre-filled by another widget via toolInput.
