Welcome to the website of a one-man amateur research and development center! Started off with game development, Sadale had developed various products, including electronic products, games, websites, desktop program, apps, music, etc. This website is a blog that mainly contains documentation of the progress of my projects as well as their release announcements. It also contains non-googleable solutions to problems that I've encountered. Scroll down to read the blogposts.
All of the products mentioned in this website are my own work, unless stated otherwise.
Core value: Development in Stability

So, I've been working on the Toy Motor Controller. Over the past weeks, I have designed the mechanical case, revised the PCB and worked on the firmware. This device is still a work-in-progress.
The mechanical case consists of front cover, back cover, a couple of knob caps, a button and a power slider switch. The battery tray is affixed to the back of the top cover using a couple of screws via a couple of screw holes that comes with the tray.
It's the first mechanical case that I've ever designed in my life. I'm glad that it's working. And I'm happy that I can finally put the 3D printer that I've got into good use. :D
Here is some photo showing the mechanical case of the second revision of PCB:
I have revised the PCB design. Compared with previous revision, now that it has the following feature:
After spending hours of time, I have assembled a unit of this revision of PCB. I found that it does have minor issues, including a couple of capacitor footprints are having the size that's slightly off, and some silk mark issues. But they aren't anything critical so I can get away without fixing them for now. :P
Here's a photo showing the difference between the previous revision and the current revision:
As for the firmware development, the driver code is mostly completed. Now that it's time for me to implement the actual feature on top of the driver code that I've written.
I've also tested the hardware using the driver code. At this stage, there's no evidence of existence of major defect in electronic design.
With the current development status, both the mechanical and electronic design seems to be working fine. I believe that I can go ahead and assemble 4-5 units of this device.
Due to the minimal ordering quantity of the PCB, I've got a few extra PCBs. I'm gonna find a time to purchase the components and solder them onto the extra PCBs.
This time over, I'm gonna purchase solder paste stencils as well. It took me hours to fix issues associated with putting incorrect amount of paste in my previously assembled units. I'd rather to spend an extra few dollars on getting stencils so that I can apply the exact amount of paste needed to avoid running into this problem again.
I don't think that this device would have any good amount of demand. I'll be using this 4-5 units to evaluate the demand and see if I should outsource the assembly or if I should continue to do the assembly on my own. I've done the math. Apparently it's well worth the cost outsourcing the assembly if the demand is >20 units per batch.
That's it for the update on this project. I'll update you guys whenever there's any news. See you soon! :)
Hello guys! I haven't been blogging about the projects that I've been working on for quite a while.
Here's new a project that I have been working on for a bit longer than a month. It's a toy motor controller.
This Toy Motor Controller is designed to be used for modifying existing motorized toys so that they'd be more fun to play with. For example, the motor of fishing game toy or penguin dash toy can be attached to this toy motor controller so that their motor can run at different motor speed, optionally with randomized movement pattern. It also supports reading external sensors so that the end-user can develop their own firmware to control the motor based on the sensor readings.
Based on my previous experience with the demand of my products, the expected demand for this project for its life time would be 10-50 units. I'll try to optimize the design for small volume production, including looking for parts that can be ordered in small volume, designing it in a way that I wouldn't have to spend too much time doing assembly even if I have to do it on my own, etc.
I kind of feel bad of starting a new project before completing the previous ones. It isn't uncommon for hobbyist projects tho. At least the completion rate of my projects is still higher than most fellow hobbyists.
After this project, I think I'll revamp my website for a little bit to make it less formal and more personal. Then I'll try getting back to my previous projects that I haven't finish (the clock and the portable game console).
Congratulation on Toki Pona language for successfully applying for the "tok" ISO 639-3 language code!
Toki Pona is a minimalist constructed language invented by "jan Sonja" back in 2001. The first official book describing the language, Pu, was published at 2014. Unlike most other constructed languages, Toki Pona has less than 130 words. Due to the simplicity of the language, it attracted lazy people like me who don't want to invest too much time into learning a language. Personally I've learned it in 2018. And the speaker of language has been growing steadily. As of today, Toki Pona is the second most spoken constructed language in the world, only after Esperanto, with the amount of speakers estimated to be about 300-1000 and counting...
Since Toki Pona language were invented, three ISO 639-3 Language Code applications were made, including at 2007, at 2017 and at 2021. With the 2007 and the 2017 request failed, Toki Pona had finally made it in 2021 and gained the "tok" language code.
I have learned Toki Pona in 2018 and have been using it since then. The one thing I've learned from Toki Pona is that, context is everything when it comes to communication, and it ain't a good idea to always take words at face value. It enabled me to talk with others more efficiently. I've also made quite a few friends speaking Toki Pona along the way. In addition, since I've learned the language, I've developed a hardware device and a game that feature the language. I've also joined Toki Pona Day 2021 showcasing another DIY Toki Pona counting device. As of this moment, yet another Toki Pona related hardware device is under development that's to be released some time in this year.
Last year I was invited to join the "Toki Pona ISO 639-3 working group". I wasn't quite active there. Right before the deadline of the application in 2021, the main applicant called for filling in the form collaboratively. I'm very glad to have involved in assisting in doing write-up of the missing parts required for application of the code along with other people in the working group. After that, the members of the Discord group "ma pona pi toki pona" were contacted and they helped editing the existing content into perfection. Just earlier today, it was officially announced by ISO 639-3 that the application was successful.
The success of this application is significant. It means that toki pona have a standard language code that can be used for localization of programs. Without a code, each program and website would have to come up with a custom code for toki pona language, assuming that it's even supported by the site in the first place. With a standard language code, it makes localization much easier. Believe it or not! Websites like Wikipedia only allows adding new languages that has an ISO language code. The lack of language code of Toki Pona had been a limiting factor of the growth of the language. With the new language code, I hope that Toki Pona language will continue to thrive!
If you haven't learned the language yet, do take a look at it! Here's a nice free online course for learning it:
o kama sona e toki pona! ona li musi a! (Translation: Go learn Toki Pona! It's fun!)
Toki Pona is a constructed language invented by jan Sonja that has hundreds of speakers around the world. Today marks the 20th Anniversary of Toki Pona language. In celebration of the birthday of the language, the ma pona pi toki pona community had organized Toki Pona Day 2021.
As a toki pona speaker, I'm very glad to be taking part in the event as a performer, as one of the sponsors and as a participant!
A month ago, I was contacted by "kala Tonyu" that I was requested to perform in "suno pi toki pona 2021" for the toki pona content that I've contributed to the internet, including ilo nanpa and the pipi song.
After some thoughts, I decided to make a sequel of the toki pona calculator, ilo nanpa lili. It's a simplified ilo nanpa that you can build on your own. It's a CD4017B-based counting device that can be built on breadboard. So I've made an assembly video, assembly instruction manual, BOM and website for the device for the event. Unlike ilo nanpa, this ilo nanpa lili is sold as a kit that the end-user would have to assemble it on their own. And it'll be sold at cost price.
The assembly video was premiered on Youtube during the event. Here's the video:
And here's the website of ilo nanpa lili that contains the BOM and shipment arrangement, so that everyone could get the kit or source the components on their own to build ilo nanpa lili.
In addition of being a performer, I was contacted by the event organizer for a request of sponsoring a unit of ilo nanpa for the event, which I gladly accepted.
In the same lucky draw, it also contained 3 units of the official toki pona book, which's known as "pu", as well as 3 units of the official toki pona dictionary, which's known as "ku". The sponsors of these items are anonymous, so I've no idea on who donated them.
Anyway, the winner of ilo nanpa in this lucky draw is jan Seno. Congratulations! I look forward to packing and sending the free unit of ilo nanpa to you!
Here comes to the most important part. In addition of being a performer and a sponsor, I'm a participant of this event as well!
This event was mainly held in the ma pona pi toki pona community, which's a community resides in stupid Discord. Despite that I don't quite like Discord, I still had to join the event, so I had no choice and joined their server. :(
Unlike the toki pona communities that I've joined, this Discord community is unique in its own way. Unlike IRC and Telegram, it supports live streaming of computer screen or phone camera right inside a voicechat. This feature was heavily utilized throughout the event. In fact, this feature enabled the performances to stream the content of their screen easily for the purpose of their performance.
Apparently, the community has stricter rules compared with other toki pona communities outside as well. I've heard rumors about unjustified banning inside the community, which I couldn't confirm, but I suspect that it's true. So I acted rather cautiously inside the community for avoid breaking any of the rules during the event.
The event was also being mirrored to Youtube and Twitch. However, the viewers there seems to be treated as second-class citizens as most of the things going on were happened in Discord. Plus, there were technical issues with the mirroring in times.
Enough talking about the Discord community. Now let's talk about the content of the event.
The event's packed with performances during the 24 hours, with a few breaks. Various performances, including games, story-telling, workshops, musical performance, were available. Some of the performances were repeated for a few times during the event so that people from different timezones would be able join. In addition, there're background games going on during the entire event. The participants were asked to fill in an attendance form, which was used for the surprise lucky draw.
There're a few musical performances during the event. I've listened to music from kala pona, jan Pensa and jan Usawi. I absolutely love the song "tawa lon linja" from jan Usawi for its catchy melody!
Spamming seems to be a part of the culture of the community. While jan Pensa was singing a song, one of them contained the lyrics "mu mu mu mu mu". Then the users kept spamming "mu mu mu mu mu mu mu mu mu mu" inside the event's channel:
In addition, when music's being played, I've seen people collectively posting the cat music gif repeatedly. And I've seen other kind of spamming from other occasions. Nevertheless it's fun to look at those spams. And it's even more fun to participate in it. :P
I've played three games during the event, including Gartic Phone, sketchful.io and Classicube. The rule of Gartic Phone is that a player would write a sentence in toki pona, then someone else would draw an image based on the sentence, then someone else would write another toki pona sentence based on the image. This process keeps repeating. In the end, the sentence would be completely different from the original one. Unfortunately, a few of the players couldn't speak toki pona well (notice how "jan li tawa wawa" get turned into "jan li kama wawa". In English, that'd be "a person runs" get turned into "a person becomes strong"). The less-fluent speakers made some extra content get lost in translation.
For sketchful.io, it's like post-it draw-it. But the host had loaded a custom word list that only contained toki pona words. It happened right before the closing session of the event. At first, around 20-30 players had joined the game. People began leaving before the game ended because it got overrun for a bit. At the end of the game, there were only like 8 to 10 players. With all those people leaving, I managed to win the game! :P
As for Classicube, it's a game similar to Minecraft Classic. It's one of the background events that the participants could join anytime during the event.
I'm impressed that the community had built a rather decent toki pona world during the 24 hours of the event:
Too bad! I felt super dizzy after playing this game for a while. So I couldn't play it for long. :(
In the closing session of the event, it's all those thanks for joining and stuffs. And there was a lucky draw as well. In the very end of the event, it was a countdown of the 20th birthday of toki pona. They counted from "mute", "mute", "mute", "mute", "mute" to "tu" "wan" "ala!". In English, that'd be "many, many, many, many, two, one, zero!". We said "many" because in the simple toki pona numeral system, all numbers more than 3 are called "mute". After the countdown, we sang happy birthday in toki pona. During the end of the event, people kept spamming in the event's channel to the extent that the moderators had to enable slow mode of Discord for the channel to slow down the spam.
That's it for the event. I'm very glad to have joined it. See you next year! :D
This year I'm very glad that I'm able to join Global Game Jam again. Here's the game that our team have developed. o lukin e ko jaki (Watching Poop)!
In this game, there're poops sliding and jumping around on the street. The player has to first memorize the path taken and the color of the poops. Then, the player would be asked a question about the poops. If the player answers correctly, a new wave of poops would come out. Otherwise the player'd lose the game.
The game is in Toki Pona using Sitelen Pona writing system.
Here's the gameplay video. What a shitty game it is, literally! :D
This game was developed in collaboration with jan N30HRTGDV and jan Niko. I'd like to thank them for forming a team with me. This game wouldn't have happened without their help. :)
Due to COVID19, GGJ's going remote this year. I've thought about taking this opportunity of remote GGJ to join another jam site. However, on second thought, I decided not to do that.
For the ease of administration, our team had decided to just join the Hong Kong Cyberport's site. That's because they're flexible and I'm rather experienced with joining this site.
All of our team members are Toki Pona speakers. Before the jam, I've managed to reach out four Toki Pona speakers interested in joining the jam. In the end only three of us ended up working on the game tho.
Originally we planned to exclusively speak Toki Pona within the team during the event. Unfortunately, one of the team members can't speak the language fluently. Therefore, we ended up switching to English by the end of the event.
However, as for the game itself, its description, and even the code of the game, they're in Toki Pona.
I'm rather impressed that I was actually able to write code entirely using this minimalist language (except for API calls and keywords of the programming language).
Since all of our members have at least a little bit experience on using Godot Engine, we've decided to use this engine. The person who's the most familiar with this engine was jan Niko. Due to some circumstances tho, I ended up being the main programmer of the team. Fortunately I've briefly revisited Godot Engine before the start of the event. And I'm surprised that my Godot skill was actually good enough for making a game for the jam. In fact, despite my limited experience, I found that I'm more efficient with Godot than with other game engines like libgdx that I've spent months on using.
With Godot engine, I've managed to pull out the following game feature in a short time, which would take quite a bit of time to do without it:
It's my first time doing any of the things above for a game. I'd seriously consider using Godot Engine for future game jams. It's easy to use, I could get the work done real fast. It's simply awesome for cranking out game features within a limited amount of time.
jan Niko had helped a bit with programming. Originally they planned to make music for the game. However, due to lack of inspiration, it didn't happen. But that's ok. It isn't like that this game requires any music.
jan N30HRTGDV had helped with designing 3D models. Originally we planned to make the entire landscape in 3D. However, after he finished the design, we agreed that the landscape wasn't good enough, and we didn't have time to fix that. Therefore, we ended up extracting a couple of models from the landscape and put them onto the original photo. Here's the photo before having the 3D models and after having them. Funny how there's a statue there having a bowl ready to hold the poops. xD
As shown above, I've added shadow to the models so that it'd fit into the photo more naturally.
I've also asked for a thumb down photo from each of our team members. Each of us had taken a photo of thumb down. They're used in the scene when the player lose the game.
I'm very glad to have collaborated with all of the team members. The jam is more fun when I'm accompanied. And I'd like to congratulate jan N30HRTGDV for having completed his first game jam! :)
Here's the list of the stuffs that I've done for the first time in my life during this project:
Here's my fuck-up during the jam: In the trailer, I've used the wrong audio filters for noise removal. It made my voice indecipherable. And I didn't add any subtitles to it. And the alien-looking writing system shown on the game wasn't helping at all. :(
I think that the fellow jammers probably wouldn't know what this game's all about just by watching the trailer. I should have used some better filters so that my voice would be more clear. If not, I should have added subtitles.
I guess I should keep this in mind if I ever join Global Game Jam on Cyberport's site again.
I was pretty much occupied with the jam and making this blogpost. After this, I hope that I'd have more time to continue on my musical training.
