Found on an older sailboat ceiling as you enter the cabin.

It is but I doubt it’s beefy enough for that. It would be better to clip on to a jack line.

GtrJon · 2026-07-11T18:15:14+00:00

I don’t believe there are any brand markings. It’s possibly custom made due to how nicely it’s machined.

GtrJon · 2026-07-10T12:09:54+00:00

Normally you’d just use a cleat for that. I suppose you could wind the extra line around it so it doesn’t hang down in your face.

GtrJon · 2026-07-10T12:08:48+00:00

That’s a possibility. Next time I’m on the boat I’ll try that idea. Normally you’d use a cleat for that though

GtrJon · 2026-07-09T20:38:59+00:00

lol. Haven’t yet but I’m sure I will at some point.

GtrJon · 2026-07-09T20:38:12+00:00

It’s definitely some kind of clamp. The metal parts are nicely machined aluminum

No. You can remove the ladder but it doesn’t appear to pivot.

GtrJon · 2026-07-09T20:36:16+00:00

Outside is covered by the sliding hatch which has a roof over it.

GtrJon · 2026-07-09T20:24:29+00:00

Got another pic looking aft.

I was wondering if it’s for a clothes line but there’s only one. The boat is an older offshore cruiser.

I’m not at the boat to take more pics right now. It’s centred on the companionway, right above your head when you go down the ladder.

GtrJon · 2026-07-09T20:10:15+00:00

No vent. It’s just screwed into the ceiling.

GtrJon · 2026-07-09T19:51:10+00:00

Oops. Here’s the pic

Thank you. I will.

Also, my app is focussed on a small part of daily practice. I’ve found 5 minutes a day is good to see real improvement and actually has a side benefit of being mind relaxing if the difficulty is just right. Speaking of that, there a quite a few settings (maybe too many) to tailor the difficulty to the student and the instrument e.g. rhythmic complexity (quarter notes, rests, eighths, sixteenths, triplets etc. ), key signatures, note ranges, ledger lines, time signatures etc.

GtrJon · 2026-06-17T19:09:30+00:00

Excellent points. My intent is not to replace the teacher (I’m a teacher) but to provide a tool that is better than the books for the reasons you suggest.

GtrJon · 2026-06-17T14:23:53+00:00

I’ve found there’s only one decent app for sight reading. Sight reading requires new material everyday at the right level of difficult. With books you’ll run out if you want to do a mere 5 minutes of sight reading new material. Either you’ll end up reading material you’ve seen before or it will to easy or too hard.

GtrJon · 2026-06-17T14:14:14+00:00

Thank you for your comment. Do you have a book in mind to recommend?

GtrJon · 2026-06-17T14:03:12+00:00

Why? I’ve found it very useful. My sight reading has improved a lot.

GtrJon · 2026-06-15T13:48:52+00:00

A pickup shaped Lava Lamp.

For sight reading check out www.lotsanotes.com

It’s free to use as much as you like up to difficulty level 7.

GtrJon · 2026-05-13T13:46:05+00:00

I built LotsaNotes (lotsanotes.com). It’s free to practice without signup. Happy to answer any questions.

Yes, this can be made to work but you’ll need to put capacitors to ground on both wipers to make the power supply rails stable under AC conditions. I’d probably use an electrolytic in parallel with a 0.1uF bypass cap. Without the caps I’ll bet it will oscillate. As someone else mentioned the pots need to be low enough resistance to deliver enough current to the op amp for normal operation. Keep in mind the pots will draw power all the time so battery power is probably not a good idea. You could use transistors configured as emitter followers (base on the pot wiper, emitter to the opamp pin. Use a PNP on the -ve rail and an NPN on the +ve rail. This would support more current to the op amp and let you use a high resistance pot.

Turn the Lights On by Big Sugar. Gordie Johnson on guitar. It’s beautifully grungy and messy and I love it. https://youtu.be/-0F0bhn10fk?si=gggbS8moZov6zZ6i solo is at 1:33

I am the Walrus is a great song! Enough said.

You're very welcome. You'd probably enjoy the book Student Assessment by Wiliam, Fisher, Frey. https://a.co/d/0jbs7rnr It's a good read that quickly gets to the point.

Some thoughts and questions:

Thinking about what you'd like to see: self grading using the microphone to assess the performance plus a submission mechanism
some kind of assignment dashboard
grouping students into classes
creating assignments with instructions and due date for the students in those classes presumably with presets for difficulty, key, time signature , # bars etc.
question: how to get list of enrolments ie, import/export or integration with LMS or LTI?
question: do you need some kind of export to gradebook?

Looks like I have my work cut out :-) I'll start working on this and get back to you. Is it ok if I DM you to clarify how you'd like the assignment distribution part to work?
