The first complex task for my drawing machine (me). About 100000 commands for the plotter pen here.

Slightly unfinished.

It seems the L293D chip is overheating, and the mechanism freezes up. Need to order a couple more and set them up in parallel, plus I’m currently printing a cover for the Arduino with a motor shield on a 3D printer, which will have a mounting for a fan to dissipate the heat.

Continuing with my English lessons.

– failure. Americans pronounce it as fai-lee-ur, while the British say fai-lyuh.

– cleanliness. Interestingly, it’s not [kleen-lee-nuhs], but [klen-li-nuhs]. For some reason, clean turns into clen.

– thoroughly – pronounced as [thur-ow-lee]. For some reason, I was inserting an “f”.

– particularly – [pr-TI-kyuh-lr-lee]. In some American dialects the letter r is pronounced, in our regions – not. It’s perfectly normal to hear it as [pa-TI-kyuh-la-lee]. Another such complicated word – primarily. I mistakenly pronounced it with the emphasis on ‘pri’. Correctly – [prai-MEH-ruh-lee]

– distributed – the emphasis is on the second [i]. [duh·STRI·byoo·tuhd]

– Draught is pronounced as draft. And means the same (about beer)

– leopard is pronounced without “o” and with the emphasis on “e”. [leh-prd]

Suddenly, perhaps someone can help with advice.

I have a problem with an old Yamaha P-120. It’s generally good, but sometimes the sound randomly disappears from the built-in speakers for half a second. Sometimes once a day, sometimes ten times, sometimes once a week. It may last a little longer or a little shorter. All indicators stay still during this. I’m somewhat familiar with electronics and can open it up to check, but I can’t figure out what might be wrong (meaning, I’m not that skilled). Hoping someone could point me in the right direction.

This has been going on for several years, so I am quite certain that: 1) it is not dependent on external factors (temperature, how long you play, what you play, how you play, whether the instrument is shaking, etc.) 2) the external audio output works—the problem is only with the built-in speakers. So, it’s unlikely to be the power supply.

I am in the USA, so there’s little use of me as a client for someone who isn’t nearby. Although, I would pay for the repair if necessary. If advice helps, I’ll tip some 🙂

My new project and the first results. Plotter! Arduino, software polargraph; plastic parts printed on a 3D printer, the rest – within 50-60 dollars total. The first prototype, made “on the fly,” I still haven’t sorted out the pen lifting/lowering properly, but the accuracy, finally, isn’t terrible like it was initially. Practically, this thing is ready to paint a wall without much modification.

A very interesting project, I will continue to improve it.

In the States, there is a social network called “Nextdoor,” where people form groups based on where they live, and you can only subscribe by confirming your address. As a result, all the neighbors get together and chat about various things. It’s quite interesting to take a peek there. For example, nearby, a turkey couldn’t handle itself and crashed into a window, severely bending it.

Or here’s someone asking what this unknown translucent thing roaming in front of his camera could be. They told him it’s a bug 🙂

I’ve always found the word “jeopardize”, meaning “to expose to danger or risk” amusing. Despite its apparent similarity to jeopard, the word originates from the French jeu parti, which means a balanced game, and was originally associated with chess (“a game in which the chances of winning and losing are balanced”).

In 1870, this word was called “a foolish and unbearable word”, and “jeopard” was then preferred – it has been around since the 14th century (from 1582). In 1828, Noah Webster, the dictionary guy, declared “jeopardize” “a modern term used by respectable writers in America, but synonymous with ‘jeopard’ and therefore useless” webstersdictionary1828.com/Dictionary/jeopardize. Nowadays, you hardly ever come across jeopard in that sense.

By the way, the word “hazard” also comes from a French game of dice (“game of chance played with dice”).
