READ BEFORE ORDERING
THIS BUILD.
THE IMPORTANT DETAILS.
- The original battery-pack and USB-cable entries are alternatives, not two simultaneous supplies. The cart budgets one USB power entry per original supply group.
- 6 Dock housings need new Tether attachment locations. Check the stud footprint, housing clearance and access to both Belt sockets at each original board location before buying.
- The 13 original strip-light location(s) use Micro Meteors in this proposal. Find 1×3 stud attachment points with 6.4 mm height clearance. Do not assume the old adhesive position will accept a housing.
- At least one 12-port board is split into a Dock 9 and Dock 3. Check room for both, leave a Belt connection between them, and keep the original light groups together where possible.
- Check thick Meteor fixtures beneath each removable storey and leave accessible Belt disconnects between floors.
- Pink lights and flashing lights need their own colour/effect checks; do not silently substitute white.
- Capacity allowance: 23 Astro light/string connectors across 36 Dock Astro ports. This checks total capacity only. Assign lights by their actual locations and confirm each Dock’s local capacity and lead reach before buying.
- This is an independently derived component plan, not a physically tested installation or a replacement step-by-step instruction manual. Use the original guide together with the concordance and changed mounting/power plan.
Connection counts are a planning check. They do not verify local grouping, cable reach, power draw or physical fit. Astro ports and Belt sockets are different connections.
How the cable allowance was calculated
19 network components require at least 18 Belt links in this planning allowance. Original cable lengths are retained where mapped; included FX Belts are credited once. Extra links use 50 cm Belts as an unmeasured routing allowance. Check the actual branch and effect grouping against every source step.
THE CONCORDANCE
EVERY CHANGE.
IN PLAIN SIGHT.
Quantities below are individual components. The shopping list combines shared packs, then rounds up once.
| Original 1.0 item | Proposed 2.0 replacement | What to check |
|---|---|---|
| 11 x White Strip Lights | 11 × Meteor Light Micro - White ↗ | One Micro Meteor per strip location. Its 1×3 Tether mount and 23.8×8×6.4 mm housing need different attachment and clearance. Fixture count is preserved; brightness and spread may differ. |
| 2 x Blue Strip Lights | 2 × Meteor Light Micro - Blue ↗ | One Micro Meteor per strip location. Its 1×3 Tether mount and 23.8×8×6.4 mm housing need different attachment and clearance. Fixture count is preserved; brightness and spread may differ. |
| 3 x White 30cm Bit Lights | 3 × Astro Light Regular - White 30cm ↗ | Keep one light at each original fixture. Route the flat lead without pinching it and confirm that its 30 cm lead reaches the chosen Dock. |
| 13 x White 15cm Bit Lights | 13 × Astro Light Regular - White 15cm ↗ | Keep one light at each original fixture. Route the flat lead without pinching it and confirm that its 15 cm lead reaches the chosen Dock. |
| 3 x Flashing White 30cm Bit Lights | 3 × Astro Light Regular - Flashing White 30cm ↗ | Keep one light at each original fixture. Route the flat lead without pinching it and confirm that its 30 cm lead reaches the chosen Dock. |
| 4 x Pink 30cm Bit Lights | 4 × Astro Light Regular - Pink 30cm ↗ | Keep one light at each original fixture. Route the flat lead without pinching it and confirm that its 30 cm lead reaches the chosen Dock. |
| 2 x 12-Port Expansion Board | 2 × Dock 9 ↗ 2 × Dock 3 ↗ | Astro ports are separate from the two Belt sockets. A 12-port board becomes Dock 9 + Dock 3, requiring two attachment locations and a linking Belt. |
| 2 x 6-Port Expansion Boards | 2 × Dock 6 ↗ | Astro ports are separate from the two Belt sockets. Mount the larger 2.0 housing with its included Tether; check the 1.0 board location has clearance. |
| 3 x 30cm Connecting Cables | 3 × Belt 30cm ↗ | Preserves the original nominal cable length. Belt plugs and routes differ; measure reach including bends before ordering. |
| 11 x 15cm Connecting Cables | 11 × Belt 15cm ↗ | Preserves the original nominal cable length. Belt plugs and routes differ; measure reach including bends before ordering. |
| 2 x 5cm Connecting Cables | 2 × Belt 5cm ↗ | Preserves the original nominal cable length. Belt plugs and routes differ; measure reach including bends before ordering. |
| 8 x Adhesive Squares | No separate purchase | Use the Tethers supplied with the selected Docks and Meteors. Find new stud attachment points; the old adhesive locations are not guaranteed to fit. |
| 1 x Battery Pack (requires 3x AA Batteries) OR | No separate purchase | Power changes to a 60 cm USB Flux Belt and separately purchased manufacturer-specified 5V/2.4A supply. Old battery/USB alternatives are not added twice. |
| 1 x USB Power Cable Note – Battery Pack will be replaced with USB Power Cables from mid April 2020 | No separate purchase | Power changes to a 60 cm USB Flux Belt and separately purchased manufacturer-specified 5V/2.4A supply. Old battery/USB alternatives are not added twice. |
| Additional 2.0 links | 2 × Belt 50cm ↗ | 19 power-network components need at least 18 links. 16 source-length Belts plus 0 Belts included with FX controllers leave 2 additional links. 50 cm is a conservative routing allowance, not a measured installation length. |
| 2.0 USB power entry | 1 × Flux Belt 60cm ↗ | One Flux Belt per retained power group (old AA/USB alternatives combined). USB adapter or power bank excluded. Multiple sources must feed electrically separate networks; never join powered outputs. |
