guys it is my pleasure to inform you all that I have found an arduino library that will receive inputs from my rc controller without messing with my hovercraft's motors

[gattsuru]

I had to run by a Radio Shack on a few occasions for electronics components right up til their eventual closure.  They had the “electronics components” as a category, but they were largely supplying them from a small stack of cabinets, and not even all of that was populated, alongside maybe two or three types of ‘general starter electronics kit’.  Forget “building a radio”: the local place didn’t even have a full E6 resistors or magnet wire.  And their staff would be better trained to sell RC cars or cell phones (the latter of which was nearly half the store by 2012) than to answer even simple electronics questions.

((Note the lack of transformers even listed on those cabinets; at best they’d have a couple variable-voltage wall warts.))

Their online catalog was better in variety -- I got a lot of copper-plated boards during their going-out-of-business sale -- but it was nowhere near competitive with online sellers even before dropshipping ate the world.  In many cases you’d be looking at three- to five-fold markup over McMaster-Carr or DigiKey prices, even including shipping.

Which... kinda points to the issue with foone’s alternate proposal. A RadioShack trying to sell to hobbyist enthusiasts would have still had to compete with the internet, and hobbyists ended up being pretty fickle about large purchases, too, no matter how much brand loyalty they might have had at a day-to-day basis.

With good reason: those electronics components cabinets often had a 10-fold markup over buying the same from local used electronics shops or 20-fold from online vendors, but if you needed a D-25 or a stack of LEDs in a hurry you’d be willing to pay a couple bucks for the convenience.  And those really weren’t enough to keep the lights on or doors open at the scale -- even small family used electronics shops have to operate at a drastically different format.  Meanwhile, if you wanted to make even a moderately-complicated electronics circuit, you’d be looking at tens if not hundred of dollars in price differences between RadioShack’s local options and online sellers.

((And, separately, the modern education system had absolutely slaughtered any interest in low-level electronics pre-Arduino, and not just as primary or secondary school levels.  I’ve talked with post-grad EEs who hadn’t touched a component smaller than a NAND gate.  The internet has done amazing things for connectivity and community among hardware enthuisiasts, but we’re still a dying breed.))

But RadioShack’s pre-00s business model sold the small stuff like transformers and capacitors so that it could also sell the big stuff: sound systems, full radio kits, so on.  Even back in the 1980s, they were far more .  The point of selling mechanical keyboards, had they made it to today, wouldn’t be to sell a handful of 50-cent cherry switches for $3 each, but that they could sell a 50-buck mechanical keyboard kit for $200.  I think that would have been a more successful approach in retrospect... but it’d also be the sort of thing that would have been ‘successful’ on the scale of a few hundred stores at most, rather than the thousands that RadioShack was operating (and often locked into).

((They did sell Arduino and RaspberryPi-style kits, mostly MAKE magazine or Seeed-variant stuff, just around 2012-2013. But they were very much marketed at Young Children Educational Gifts rather than viable projects.))

Microcenter and some hardware stores have taken that approach, and they do exist -- though it’s still not their core focus so much as a way to drive other sales -- but they’re the sort of business that can only support a location or two per city, rather than the convenient strip-mall front that RadioShack aimed for.

Does anyone remember what happened to Radio Shack?

They started out selling niche electronics supplies. Capacitors and transformers and shit. This was never the most popular thing, but they had an audience, one that they had a real lock on. No one else was doing that, so all the electronics geeks had to go to them, back in the days before online ordering. They branched out into other electronics too, but kept doing the electronic components.

Eventually they realize that they are making more money selling cell phones and remote control cars than they were with those electronic components. After all, everyone needs a cellphone and some electronic toys, but how many people need a multimeter and some resistors?

So they pivoted, and started only selling that stuff. All cellphones, all remote control cars, stop wasting store space on this niche shit.

And then Walmart and Target and Circuit City and Best Buy ate their lunch. Those companies were already running big stores that sold cellphones and remote control cars, and they had more leverage to get lower prices and selling more stuff meant they had more reasons to go in there, and they couldn't compete. Without the niche electronics stuff that had been their core brand, there was no reason to go to their stores. Everything they sold, you could get elsewhere, and almost always for cheaper, and probably you could buy 5 other things you needed while you were there, stuff Radio Shack didn't sell.

And Radio Shack is gone now. They had a small but loyal customer base that they were never going to lose, but they decided to switch to a bigger but more fickle customer base, one that would go somewhere else for convenience or a bargain. Rather than stick with what they were great at (and only they could do), they switched to something they were only okay at... putting them in a bigger pond with a lot of bigger fish who promptly out-competed them.

If Radio Shack had stayed with their core audience, who knows what would have happened? Maybe they wouldn't have made a billion dollars, but maybe they would still be around, still serving that community, still getting by. They may have had a small audience, but they had basically no competition for that audience. But yeah, we only know for sure what would happen if they decided to attempt to go more mainstream: They fail and die. We know for sure because that's what they did.

I don't know why I keep thinking about the story of what happened to Radio Shack. It just keeps feeling relevant for some reason.

How To: Make A RC Dinosaur That You Can Control

Do you think something's wrong? Click me to try rc dinosaur.

RC (radio control) dinosaurs have become an extremely popular hobby in recent years. Whether you’re a fan of Jurassic Park or just love messing with your friends, these dinosaurs are a fun way to spend your free time. Making your own RC dinosaur is not as difficult as you may think, but there are a few guidelines that will help make the process smoother. In this blog post, we will walk you through the steps needed to make your very own RC dinosaur.

The Different Types of RC Dinosaurs

There are a variety of different types of RC dinosaurs that you can make and control. You can choose from a wide range of dinosaur species, such as the T-Rex, Triceratops, and Stegosaurus. These dinosaurs come in a variety of colors and styles, so you can create a unique model. To make your own RC dinosaur, you first need some supplies. You'll need an electronic controller, RC servo motors, and batteries. The electronic controller is what will control the movements of the servo motors. You can find these controllers at most hobby stores or online retailers. Next, you'll need to assemble your dinosaur model. Start by placing the RC servo motors on the skeleton body parts of your chosen dinosaur model. Make sure that the motor shafts are facing forward and that the leads are attached to the skeleton body parts securely. Once everything is attached, connect the battery cables to each servo motor and insert them into the corresponding sockets on the electronic controller. Now it's time to get started with the controls! You'll need to locate the "joystick" on your electronic controller and move it around to control movement of your dinosaur model. Be sure to experiment with different motions to see which ones work best for controlling your dinosaur's movements.

How to Control Your RC Dinosaur

There are a few things you'll need to get started before you can control your RC dinosaur: an RC controller, a battery, and a transmitter. The RC controller is the brain of your dino. It sends commands to the transmitter, which then tells your dinosaur what to do. There are many different types of controllers available, so it's important to find one that fits your needs. Some controllers have built-in screens and others require you to use separate screens. Some transmitters allow you to control multiple dinosaurs at once, while others are designed specifically for one dinosaur. It's important to find a transmitter that matches your controller and dinosaur. To power your RC dinosaur, you'll need a battery. Most batteries come in packs of two or four, so make sure you have enough for your dinosaur and controller. You can also buy individual batteries if needed. Now that you've got all the supplies necessary, it's time to get started Control Your RC Dinosaur!

Conclusion

In this article, we will be teaching you how to make a RC dinosaur that you can control using an Arduino board and some simple programming. By following our steps, you will be able to create your very own remote-controlled dinosaur that is sure to delight both children and adults alike! If you have any questions or difficulties along the way, do not hesitate to contact us at support@learnardc.com. We would love to help you get started on your RC Dino project!

シンセ開発ログ 2023-01-03: 16ビット出力対応のArduinoシンセ「VRA8-U type-16」をリリース

16ビットのオーディオ出力に対応したArduino Uno用シンセ「VRA8-U type-16」をリリースしました。「VRA8-U」v2.0の新機能（VRA8-Uの特別版）という位置付けになります。 https://github.com/risgk/digital-synth-vra8-u/releases/tag/v2.0.0

以下の回路図のように、L/RチャンネルそれぞれでPWM出力ピンを2個ずつ使って、上位8ビットと下位8ビットのPWM出力を抵抗で重み付けしてミックスしています。下位8ビットには、RCフィルタ（LPF）が効き過ぎますが、私の感覚では特に気にならず、量子化ノイズは大きく減ります。減衰系の音色でも、量子化ノイズが気になりません。オーディオ出力については、「シリーズ最高音質」と言って良いかと思います。

製作には、VRA8-Uの推奨部品に加えて、56kオームの抵抗が2個必要になります。なお、SparkFun MIDI Shield（DEV-12898）を使う場合は、S4（D3）とLED2 GREEN（D6）をハンダ付けしないようにしてください。

「VRA8-U type-16」 では、コーラスエフェクトが一部制限されます： ・Chorus Mode "Mono Chorus" と "Stereo 2-phase Chorus" が使えません（CPUパワー不足のため） ・Chorus DepthとChorus Delay Timeの効果が半分になります（RAM不足のため） そのため、プリセットのChorus Modeは "Pseudo-Stereo Chorus" に変更しています。このコーラスは、左右チャンネルを加算するとディレイ成分が消えてしまうタイプなのでご注意ください。ステレオ2相コーラスなどを使いたい場合は、Chorus Bypassを “On” にして外部エフェクターを使用してください。

16ビット出力については昨年も検討したのですが、CPU/RAM的にVRA8-Uの全機能を実現できないことがわかったので、導入を見合わせました。しかし最近、「特別版」ならある程度の制約を設けても良いのではないかと考え直しました。これから作るArduino用シンセは、16ビット出力を基本にしたいです。

Fabble（作り方）のページはまだ直していませんが、後で更新します（追記：更新しました）： https://fabble.cc/risgk/digital-synth-vra8-u

Here's my list of completed projects, because I wanted to show off a little. I'm trying for chronological order, but I honestly could be off by years for some of these, and I'm only listing the ones that are pretty directly audio-related. It turns out there are even more than I thought: not 41, but 49.

Wheelie CV source (robot motor/gearbox with wheel & tire run as generator)

And I'm probably still forgetting a few. I'll admit, that's a bit of an ego boost. Some of these could use some refinement, but they're all in a usable condition.

Have I talked about something that's not on this list? Want me to elaborate on any of these?

I wanted to take stock of my general DIY synth/audio situation by making a list of open projects. The list doesn't count things that I've looked at and said, "Oh, that would be cool" or "I should build one of those", just the projects that I've put some degree of effort into, whether that be drawing out schematics or designing control layouts or acquiring parts or whatever. And it turns out I have — at a probably incomplete count — 32 unfinished projects that I can put names, or at least descriptions, to.

Which is just a little disheartening, you know? So many things undone. But then I thought to turn it around, and I also made a list of the projects I have completed, with the same level of granularity. And you know, there are 41 items on that list, and again I'm probably forgetting a few.

It's all perspective, right? I really haven't been making electronic musical instruments and gadgets for that long; I didn't even learn to solder until 2013 or so, and nothing on the list is more than 10 years old, most a lot newer; everything in my Eurorack case — including the case! — didn't exist two years ago, though some pieces had been planned for much longer than that. So here's to more projects!
