# Grant resource ledger

Prepared September 30, 2026 for the Love Burn 2027 application. One ledger
with three columns of truth: **cash** the grant can buy, **in-kind** the artist
already owns or commits, and **requests** to the event. The machine-readable
version is `assets/grant-resource-ledger.json`, generated by `just grant-ledger`
from the sourced bill of materials `assets/grant-build-bom.json` and the
existing pricing options; `just grant-ledger --check` verifies it. The
generator reproduces the published pricing table before writing anything.

Every price below is either a retail price observed on September 30, 2026
(linked in the bill of materials) or an allowance marked as such. Nothing is
reserved, quoted or purchased. Tax and shipping are not included.

## What to ask for

Love Burn publishes its finances. The latest finance PDF on the disclosure
page shows the cash art-grant pool and the number of projects it funded, which
gives the only documented size of a typical award. (The links labelled 2026
and 2025 on that page resolve to the LB2024 and LB2023 files; those are the
latest years available.)

| Love Burn year | Cash art grants | Projects | Average per project |
| --- | ---: | ---: | ---: |
| LB2024 | $440,092 | 210 | $2,096 |
| LB2023 | $387,071 | 149 | $2,598 |

The Tier 1 build costs $2,378–$5,242 in cash. The live form sorts requests
into tiers: Spark $0–599, Seed $600–3,000 ("simple to medium builds,
portable art, or small interactive pieces"), Feature $3,000–15,000 ("large,
high-impact art that helps shape the event"), Anchor above $15,000. This
build is a Seed project. **Ask: $3,000 cash as a Seed Grant plus 3 crew
tickets** (the form values crew tickets at $500 each), itemised against the
table below. $3,000 covers the low build in full; Andrew covers any remainder
and every in-kind line. Tier 2 is shown as an add-on so the committee can
fund it separately if it wants four-sided coverage. Andrew confirmed the Seed
tier on September 30, 2026.

## Tier 1 cash: hung 2.5 m sphere, two purchased projectors

| Tier 1 cash line | Qty | Low | High | Kind |
| --- | ---: | ---: | ---: | --- |
| The moon: the artist's 2.5 m walk-in zorb (TPU sphere), one person inside at a time, projected onto; diffusing liner or skin treatment allowance | 1 | $0 | $700 | allowance |
| Optoma HD146X 1080p DLP projector, 3,600 lumens | 2 | $998 | $1,198 | observed price |
| Output node at the projectors: N100-class mini PC with two HDMI plus DisplayPort or USB-C, fed over Wi-Fi by the owned laptop ($0 if the laptop drives the heads directly) | 1 | $0 | $200 | observed price |
| Output-node accessories: weatherproof box, HDMI leads (the private Wi-Fi is the owned UniFi router) | 1 | $40 | $90 | allowance |
| Old phones inside the zorb running the project's own app: camera feed and mic feed to the laptop, looking and listening out through the clear skin (owned, or second-hand at Andrew's USD 25 budget) | 2 | $0 | $50 | allowance |
| Phone mounts and power banks inside the zorb (or a magic arm per phone on the triangle corners) | 2 | $30 | $44 | observed price |
| Weatherproof switch at each spot (foot switch or big arcade button) that turns the AV inside the zorb on and off when someone steps in | 2 | $20 | $40 | allowance |
| 13 ft heavy-duty light stand for each projector | 2 | $128 | $128 | observed price |
| Universal projector bracket per stand | 2 | $36 | $38 | observed price |
| Rain and salt-spray cover per projector (vented box or hood) | 2 | $120 | $300 | allowance |
| Rigging kit: block, horn cleat, 15 m halyard, rated lyra-style swivel, optional porch-swing springs, slings, shackles, carabiners, safety sling, tag lines, straps, sandbags | 1 | $150 | $400 | allowance |
| Outdoor-rated cords, inline GFCI, cable ramps, weatherproof power box | 1 | $150 | $300 | allowance |
| Weather-resistant powered speaker fed from the Pi | 1 | $100 | $250 | allowance |
| Landed configuration: three pinned tube legs with foot pads for the triangle, mats and sandbags | 1 | $100 | $300 | allowance |
| Repair kit, tape, spare blower fuse, batteries, lens cloths | 1 | $50 | $150 | allowance |
| Basket under the sphere: a 3.1-3.5 m straight-tube triangle (or a 1.8-2.0 m rolled ring) in 1 in EMT or 3/4 in steel tube, three-rope bridle, pads, three straps over the top | 1 | $60 | $180 | allowance |
| Subtotal | | $1,982 | $4,368 | |
| Contingency 20% | | $396 | $874 | |
| **Tier 1 cash total** | | $2,378 | $5,242 | |
| Third projector (continuous wrap), with contingency | | $902 | $1,345 | |
| Tier 2 add-on (four projectors), with contingency | | $1,643 | $2,344 | |
| Option B truss goalpost, artist-funded, with contingency | | $1,010 | $1,824 | |

Why these parts, in Andrew's words: Pi for playback, the five-hundred-dollar
projectors instead of rental, fifty-dollar phones as cameras, hang it from the
rig he already has or a tree, telescoping stands for the projectors, and rest
it on the ground as the worst case. The rental study priced six days of a
$495-per-day projector at $2,970 per projector; buying a 3,600-lumen unit for
$499–$599 is cheaper for one event and leaves the artist with the hardware.

## In-kind: owned or committed by the artist

| Item | Owner | Status | Note |
| --- | --- | --- | --- |
| Aerial rig (model and attachment height to confirm) | Andrew | committed | The hanger Andrew owns. Its manual decides the load; the sphere must fit between the legs, see the fit check on the application page. |
| Hazer | Andrew | committed | Zero acquisition cost (P015). Fills the zorb with haze during inflation; fluid is a consumable. |
| Laptop | Andrew | committed | Pre-owned. Real-time compositing host; streams the finished picture to the output node or drives the heads directly. |
| UniFi router | Andrew | committed | Owned. Private Wi-Fi for phones, laptop and node; no internet; nothing stored. |
| 2021 Ram 2500 Mega Cab | Andrew | committed | Transport only; carries no load and is not part of the 2027 art. Parking it at the camp as scenery is a later option. |
| Design work to date (v3, v4, diagnostics, content studies) | Andrew | committed | Already produced; on the project site. |
| Labour: content, bench tests, build, install, nightly operation, strike | Andrew and crew | pending | Crew names and hours to be entered. |
| Travel: fuel, tolls, lodging to Virginia Key and back | Andrew | pending | Artist-funded; not estimated here. |

## Requests to Love Burn

| Request | Status | Note |
| --- | --- | --- |
| Cash grant toward the Tier 1 list | requested | $3,000, Seed Grant tier |
| Artist tickets for the build and operating crew | requested | Count to be entered; tickets follow an approved proposal |
| One 120 V 20 A outdoor circuit, dusk to midnight | requested | Measured load schedule after the bench test |
| Dry-land placement, 10 m x 10 m, clear overhead, 1.5 m around the legs | requested | No shoreline or over-water placement for 2027 |

## Fallbacks written into the application

If the rig is refused, the moon lands: three pinned legs on the triangle
stand it like a probe at the same 1.7 m centre and under 10 ft (nothing
overhead, nothing to climb, sandbags on the pads); if the truck is kept
out, it is transport only; if power is
refused, an inverter generator under 5,000 W at the artist's cost; no haze,
no tree and no shoreline are never assumed; wind means lowered and strapped,
then deflated. The packet carries these under "Anything else" and the permit
answer, so placement can say yes to any version.

## Every option on one scale

The cockpit and pricing page let Andrew pick any of the eight layouts. The
ledger carries all of them at the pricing page's defaults (six rental days at
$495 per projector, 25% contingency, no credit, no tax) next to the Tier 1
purchase-based build, so whichever option is chosen, its cash figure is here.

| Option | Projectors | Basis | Cash low | Cash high |
| --- | ---: | --- | ---: | ---: |
| Tier 1: hung 2.5 m sphere, purchased projectors | 2 | purchase | $2,378 | $5,242 |
| A lit moon on the ground | 0 | rental | $4,500 | $13,750 |
| Ground-supported hemisphere | 1 | rental | $9,338 | $21,463 |
| Full sphere on a ground cradle | 2 | rental | $19,300 | $39,675 |
| Fixed in the truck bed | 2 | rental | $21,050 | $44,050 |
| Freestanding fixed pedestal | 2 | rental | $22,675 | $47,175 |
| Hang from an existing approved point | 2 | rental | $21,675 | $44,675 |
| Fixed truck cantilever | 4 | rental | $42,975 | $79,850 |
| Hang from a freestanding gantry | 4 | rental | $36,975 | $67,975 |

The rental options also carry professional review, fabrication and insurance
allowances that Tier 1 does not need because nothing is engineered: an
zorb of tens of kilograms, plus one person when the rating allows it, on rated rigging within the rig's manual. If
Andrew chooses a rental option for the application, its row above is the cash
figure and the in-kind and request tables still apply.

Prior art, the two-versus-three projector geometry and the camera arms are in
[prior art and mounts](grant-prior-art-and-mounts.md), which also holds the
lowering design. Andrew's floor if funds get tight: one HD146X on one face,
not two handheld projectors; Codex's workbook rates the handheld class
bench-only and its cheapest useful one costs about the same as an HD146X.

## Projector and controller shortlists (Codex workbooks, September 30)

Andrew supplied two research workbooks, preserved beside the other dated
research originals as `source/research/2026-09-30/Enceladus_Projectors_40_to_20.xlsx`
and `…/Enceladus_Microcontrollers_40_to_20.xlsx` (40 candidates screened to 20
each, prices checked September 30, 2026, no hardware tested).

**Projectors.** The workbook was built for the 3.4 m truck design: it
screened short-throw and portable classes against a 6 m enclosing frame and
cut standard-throw units because that frame needs a long side reach. Its
cheapest full-size short-throw candidates are the Optoma ZH350ST (laser,
0.496 throw, 3 kg, $1,499) and ViewSonic LS711HD (4,200 ANSI, $1,399.99,
out of stock direct); its handheld class (XGIMI MoGo 4 $479, Kodak LUMA 150
$239.99) is bench-only and too dim for a 2.5 m sphere outdoors. For the Seed
build the geometry is different: a 2.5 m sphere with projectors 4 m out, where
the standard-throw Optoma HD146X (3,600 lumens, $499 to $599) fills the sphere
and two of them cost less than one ZH350ST. The ZH350ST is the upgrade path
when funds allow: 1.25 m from the sphere, shorter stands, no walkway crossing,
no lamp to replace. One returnable test head before buying four remains the
workbook's advice and ours.

**Controllers.** Tier 1 needs none: the phones inside the zorb are the
cameras and the mini PC (or laptop) composites and drives the projectors
over HDMI, two or three outputs; the projectors have no wireless input and
cheap wireless projectors are too dim, so cables it is.
If a wireless sensor node is added later, the workbook's top finalists are
the Seeed XIAO nRF52840 Sense ($15.99, integrated motion), XIAO ESP32S3
($7.49) and Raspberry Pi Pico 2 W ($7.70); its cabinet-grade Arduino Opta and
Portenta boards ($166 to $300) belong to the large design, not this one.

## Rig fit, before buying the sphere

Needed attachment height = sphere diameter + 0.3 m ground gap + 0.6 m bridle
+ 0.2 m hardware + 0.3 m movement (the comparison formula from the mount
research). The sphere must also pass between the sloping legs at its widest.

| Rig nominal height | Attachment height | Largest sphere by height |
| --- | ---: | ---: |
| 12 ft | 3.66 m | 2.2 m |
| 16 ft | 4.88 m | 3.4 m |
| 20 ft | 6.10 m | 4.7 m |

A 2.5 m sphere therefore needs about 3.9 m (12.8 ft) of attachment height; a
12 ft rig means a 2 m sphere. Andrew's rig model sets this. The wind limit
comes from the rig manual and the lowering drill, not from this table.

## Hanging it: the sphere side and the support side

**The moon is the zorb (Andrew, September 30).** A TPU zorb weighs tens of
kilograms (a 3 m one 80 to 100 kg), is double-walled for a rider, and has
no rated top point, so nothing hangs from its skin and the rigging is rated
gear sized for that weight: a padded steel loop seat, a fabricated triangle,
a three-line bridle, a rated swivel, and a hand winch with a brake instead
of a bare cleat. The skin must diffuse light for projection (frosted or
white, or a diffusing liner); the October bench test proves that first. If
Andrew does not already own the zorb, its purchase is a different price
class from the event-sphere allowance and must be priced before the build.
A PVC cage around the sphere is
not worth it: weight, wind area and shadows. Best of all is Andrew's
basket: a 1.8 to 2 m ring, or better a 3.1 to 3.5 m straight-tube triangle,
under the sphere, hung by a three-rope bridle from its corners, with three
straps over the top; nothing attached to the skin, any cheap sphere, no
rigid legs (they would shadow the projection). A bought lyra is too small;
Andrew fabricates the frame at Denhac with Odd Todd (materials are a Tier 1
line; labour in-kind). Hang it through a rated
swivel like a lyra; the projected image does not care if the moon turns.
Geometry, prices, prior work and the bouncy porch-swing-spring option are in
[prior art and mounts](grant-prior-art-and-mounts.md).

**Cheap static metal, done right, is a lighting goalpost, not a weld.** Two
ProX XT-CRANK14FT-220 crank stands (14 ft, 220 lb each, TUV certified, 63 in
base, about $316 to $400 each on sale) with a 10 ft aluminium truss span make
a rated, resellable goalpost that fits in the truck and, critically, cranks
the moon down in wind in a minute. A custom welded tripod costs about the
same in material and shop time, is rated by nobody, and cannot be lowered.

| Option B support (artist-funded, outside the Seed ask) | Qty | Low | High |
| --- | ---: | ---: | ---: |
| ProX XT-CRANK14FT-220 14 ft crank stand | 2 | $632 | $800 |
| 10 ft aluminium truss span (ProX T-LS31M $169.95 to Global Truss F34 9 ft $600) | 1 | $170 | $600 |
| Half-couplers, safety steel, sandbags | 1 | $40 | $120 |
| **Support subtotal, before contingency** | | **$842** | **$1,520** |
| **With 20% contingency** | | **$1,010** | **$1,824** |

Use it only if the owned rig fails the fit check. Andrew offered to self-fund
or run a small sponsor drive for anything above the Seed grant; the form's
Art Sponsor Tickets ($500 each) are the built-in way to do that.
