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 🙂
