What is physically owned for the hardcut bench, as opposed to what the design specifies. hardcut previously recorded parts only as “reported in hand” — this is the receipts version.
This note is hardcut-scoped and is superseded for global purposes by inventory
It records 9 of order H26/7333913’s 26 line items — only the ones hardcut’s bench tasks need. Do not read it as an inventory of what is owned. For “do I already have one?”, go to inventory, which carries the full order, the two amendments the cart XML does not contain, the confirmed-absent list, and the cikkszám↔URL rule.
What stays here and is not duplicated there: the bench-substitute vs production-BOM distinction below, and the Task 8 wiring context.
For Agents
Source of truth for what was bought: HESTORE order H26/7333913, placed 2026-08-08, arrived 2026-08-11. Cart export on disk:
/Users/levander/Downloads/hestore_20260808.xml(a<hestore><item cid=… quantity=…>XML — HESTORE cikkszám is thecid). This is a seed, not a system. It lists only what hardcut’s bench tasks need. See the open question at the bottom.
Instruments
| Item | Cikkszám | Qty | Price | Notes |
|---|---|---|---|---|
Logic-24M-8CH logic analyzer | 100.355.03 | 1 | 3 975 Ft | CY7C68013A (FX2LP) Saleae clone, 8 ch / 24 MHz, USB 0x0925/0x3881 (impersonates the original Saleae Logic), sigrok driver fx2lafw. Full toolchain + two gotchas: 2026-08-29-logic-analyzer-toolchain |
| TESTHOOK1-RD clip-on probe hooks, red | 100.420.73 | 2 | — | For the analyzer |
| TESTHOOK1-YE clip-on probe hooks, yellow | 100.420.74 | 2 | — | For the analyzer |
Four hooks, eight channels — a five-node Task 9 capture needs the hooks plus jumper wire into the breadboard.
Task 8 Bench Parts (same order)
The breadboard substitutes named in Task 8: Breadboard the front end, flip-flop and shunt, all in hand:
| Item | Cikkszám | Qty |
|---|---|---|
| 74HC14-CF hex Schmitt trigger | 100.429.88 | 2 |
| 74HC74 dual D flip-flop | 100.215.54 | 2 |
| IRLZ44NPBF logic-level N-FET, TO-220 | 100.314.93 | 5 |
| BB-102 breadboard, 56×165 mm | 100.285.27 | 1 |
| RPACK-600 resistor kit, 10 R – 1 M, 20/value | 100.402.99 | 1 |
| SS-5GL microswitch, SPDT snap-action | 100.457.13 | 2 |
These are bench substitutes, not the production BOM
Task 8 breadboards at 3.3 V with 74HC14 / 74HC74 / IRLZ44N. The design’s production parts are 74LVC1G17Q Schmitt buffers and BSS806N FETs, plus the LM74700-Q1 → SMBJ33A → LM5164-Q1 → AP2112K-3.3 supply chain — none of which were bought. See Build Order.
Resolved: The Vault-Wide Inventory Now Exists
Raised 2026-08-13, graduated 2026-09-02 → inventory
The original question was “we need a better way to track our electronic projects in obsidian, like manage inventory, reorders etc.”, withdrawn nine minutes later in favour of handling the project more broadly — so what was built is a note, not a system: no reorder workflow, no automation.
Parts used to live scattered across Boards on Hand, lightaim and this note, with nothing tracking a part across projects. inventory is now that record. It immediately paid for itself by catching the MINI560-5V-5A (
100.423.75) being wanted independently by lightaim and the KrakenSDR car rig.
