|
| Last year PlasticList discovered that 86% of food products they
| tested contain plastic chemicals--including 100% of baby food
| tested. The EU just lowered their "safe" BPA limit by 20,000x.
| Meanwhile, the FDA allows levels 100x higher than what Europe
| considers safe.
|
| This seemed like a solvable problem.
|
| Laboratory.love lets you crowdfund independent testing of
| specific products you actually buy. Think Consumer Reports meets
| Kickstarter, but focused on detecting endocrine disruptors in
| your yogurt, your kid's snacks, whatever you're curious about.
|
| Here's how it works: Find a product (or suggest one), contribute
| to its testing fund, get detailed lab results when testing
| completes. If a product doesn't reach its funding goal within 365
| days, automatic refund. All results are published openly.
| Laboratory.love uses the same methodology as PlasticList.org,
| which found plastic chemicals in everything from prenatal
| vitamins to ice cream. But instead of researchers choosing what
| to test, you do.
|
| The bigger picture: Companies respond to market pressure.
| Transparency creates that pressure. When consumers have data,
| supply chains get cleaner.
|
| Technical details: Laboratory.love works with ISO
| 17025-accredited labs, test three samples from different
| production lots, detect chemicals down to parts per billion. The
| testing protocol is public.
|
| So far a couple dozen products have received some funding, six
| products have been fully funded (five product results published,
| the sixth is at the lab as I write this!)
|
| You can browse products, add your own, or just follow specific
| items you're curious about: https://laboratory.love

|
| With the autoloader, one script tag loads components dynamically

|
| Theming uses color-mix() and OKLAB to create uniform color

| for dark mode.
|
| All form controls are form-associated via ElementInternals and
| work with native validation APIs (required, pattern, etc.).
|
| Dialogs, popovers, tooltips, etc. use Popover API for top-layer
| access without having to portal or hoist.
|
| Some of the more fun components include: Joystick, Stamp, Mesh
| Gradient, Flip Card, Random Content, Intersection Observer,
| Typewriter, Lorem Ipsum, Slide Activator
|
| The library is free for personal, educational, non-profit use.
| Commercial use requires a license.

|
| The most effective solution I've found is to take the top speed

| BPM with sloppy attempts, then dropping it back down to 130-140
| BPM.
|
| I've gone cleanly from alternate picked 140 BPM triplets to 220
| BPM triplets in two months after being stuck at 140 BPM for over
| a year with this method. Sometimes even hitting 280 BPM triplets
| when I have the focus and time for it.
|
| Even then, I want a more consistent, and variable way of
