The WILD Ball

WILD Ball - electronic DIY aid in WILD induction

What is a WILD Ball?

WILD Ball is the name I have given my little project to build a device that aids a person in falling asleep more consciously and possibly experience waking-initiated lucid dreams.

It is a tennis ball sized device that you hold in your hand while trying to fall asleep consciously (usually after a WBTB). WILD (waking-initiated lucid dream) is referring to my preferred way to experience dream consciousness.

(How) Does it work?

The most common reason why WILD attempts fail is that the critical moment - the exact moment where you start to perceive the dream instead of your physical surrounding enough to control the dream consciously - is simply missed. You stay awake for a while, and when/if you finally fall asleep, you don't notice it. It is important to stay aware until or become aware right at that moment where you already perceive a dream but are still conscious enough to control it. There is a variety of mental and a few physical techniques that are supposed to help one to accomplish just that. This device is an additional aid to mental techniques. As with other electronic devices made to aid lucid dream (LD) induction, it is expected to work best if you already have experience in successful LD induction. Of course it is not necessary to have experienced LDs before in order for this device to help accomplish this goal. I suggest its usage as a part of the WILD induction training of anybody who sees it as a fitting addition to their WILD practice. If you already have the ability to explore hypnagogic hallucinations extensively or sometimes experience the beginning of a dream without becoming lucid, this device might fill a gap in your LD practice.

The WILD Balll has two different usage modes. (More might be added in the future.) Both aim to remind its user of their intention to fall asleep consciously by sounding a buzzer whenever the muscle contraction of the hand that is holding it drops below a certain threshold. It is an old technique to hold something in one hand and let it fall on something that makes a noise, thus waking one up right at the moment where muscle contraction is too weak to hold the object. This technique is seldomly discussed in the lucid dreaming community though and I have found only a handful of reports of people experimenting with or using it. Using an electronic device instead of a heavy object and a noisy underground has some advantages which might overcome the limitations that the classical approach has.

  • The type of sound can be altered in software. The built presented here only provides a simple piezo buzzer. But the design can easily be extended to play more complex sounds or music.
  • The length and volume of the sound can be altered in software, making it easier to tune it to your personal requirements.
  • The device can be used at any sleeping place and does not need to be set up before use when travelling.
  • By using headphones or a speaker pillow a loud alarm sound can be played for the user without disturbing other sleepers in the same room.
  • Obviously it is cooler to do it this way than to rely on simple physics.

Mode 0 imitates the classical approach of letting the object fall when the muscle contraction becomes weak. The alarm sound is triggered when the device is moving at a certain speed or above. Movement is detected in three axes independently. The speed threshold can be simply set in software. If you want to move your hand or otherwise adjust your body during a WILD attempt without triggering the alarm, you can simply squeeze the device, which disables the sound until you let go and only hold it lightly again. For more uses of mode 1, see Ideas/modifications below.

Mode 1 follows a different approach to achive the same result. You steadily squeeze the device during your WILD aatempt. As soon as the pressure drops below a certain threshold the alarm sounds for the defined duration. Right now this a implemented with a binary switch which means the threshold can not be adjusted in software but only changing the the way the switch is built, by using a different pre-manufactured switch or by changing (the hardness of) its surrounding (the ball itself). The switch could be replaced with a preassure sensor to allow more gradual detection of preassure loss.

The code

If you have a device built according to the above pictures then you can use the below Arduino sketch (download .ino file) as it is. Otherwise it should give you an idea of how to program the microcontroller used in your DIY built.

Ideas/modifications

(tbc)

The device does not have to be placed inside a ball. You can built a case and place the components according to your personal needs. Because it does not have to drop on anything but only move it is also possible to use mode 1 with the device strapped to the hand if you prefer to hold up an arm instead of holding something in your hand. If you usually experience muscle twitches while falling asleep, e.g. in your legs or feet, as many people do, you can also experiment with the device strapped to your foot or leg.

Instead of sounding a buzzer for a pre-defined duration, you can experiment with different signals, be it blinking LEDs a playing an MP3 file from a different device or extension module. By adding a wave module the variety of sounds can be increased so that you can choose the best sound to make you aware quickly without waking you up completely. You yourself probably know best what sound that might be. But as with the rhythm nappping technique, short loud sounds are most likely to lead to a successfull LD induction attrempt.

Traumtagebuch-Software

Die eigenen Träume aufzuzeichnen ist ein wichtiger Teil des Klartraum-Trainings. Das ist der Haupt-Grund, wieso ich daran interessiert bin. Aber es kann auch aus anderen Gründen interessant sein, Traum-Erinnerungen aufzuschreiben oder sonstwie aufzuzeichnen.

2017 habe ich mir mal fast alle Software für Android und Windows, die für diesen Zweck gedacht ist, angeschaut. Die Idee war, Features und Funktionsweisen aller möglicher Apps in einer filterbaren Tabelle geordnet und vergleichbar zu sammeln und anderen mit Google Docs zu ermöglichen, die Tabelle zu erweitern und zu ergänzen. Allerdings habe ich in meiner aktiven Zeit in der Klarträumer-Community niemanden gefunden, der interessiert war, mitzumachen. Deshalb lege ich jetzt einfach die Tabelle mit Stand von Oktober 2017 in seiner gänzlichen Unvollständigkeit hier ab.

Da sich die persönlichen Vorlieben und Bedürfnisse stark unterscheiden, wage ich es nicht, Empfehlungen auszusprechen. Unter den >100 getesteten Apps sind sehr unterschiedliche Apps dabei. Hoffentlich hilft die Tabelle, Interessierten die Auswahl zu erleichtern.

I would like to participate in a bathing competition some time.

When I was working half-time I was making and doing fun things and hobbies were hobbies. Now - working full-time - I spend too much time being annoyed that I don't have more free time. Accepting that this is life is the most cowardly thing I've done. Good thing I notices in time.

    Project: mixlog

    I just canceled some domains that I had registered. Among them were the domain names mixblog23.de and mixlog.de. Both of which were once used for a blogging platform of mine that wasn't alive for a long time. But I kept the domains just in case. (I don't know which case that would have been.)

    The platform was initially supposed to be called Mixblog, but I couldn't find a free domain name that I liked. So at some point I registered mixlog.de, which by now sounds better and more familiar to me anyway.

    The point of mixlog was - apart from me having a website to build and something to learn on - to create personal feed of content from different blogs on that website and other sources (RSS feeds). It could essentially be used as a feed reader in a web browser with the ability to publish stuff on the same site. RSS aggregation wasn't scaling well, so it would have been difficult if many people would have used it as a feed reader for many feeds. But that wasn't its main purpose anyway. So, you could post blog posts, image galleries (which technically were blog posts too) and links to posts on other websites (which imported the content and worked as a repost). You could follow blogs and repost and fav posts from bogs on mixlog and from other blogs as well. Classic blog comments existed too. Pingbacks and RSS feeds were supported as I still liked to think was standard back then.

    I saw the platform as like sort of a twitter with fewer members, more features and without contrains (no small character limit, reblogging and following blogs from other websites was supported). When I later learned about tumblr, I started to think of mixlog as like sort of a tumblr with more features and a less professional design and UI. But I don't think tumblr even existed when I stopped working on mixlog.

    So why isn't mixlog around anymore? At its peak there were three active users on the platform (not daily active, far from, actually). That included me, a friend who tested it with me in the early development stage and another friend, who tried it out for a short while. Altogether there were four user accounts/blogs. And mine was the only one that showed sings of prolonged motivation to post stuff. So when it became clear to me that nobody but me would be using it I thought it to be overblown for a personal weblog, stopped adding features and eventually took it offline instead of fixing a potential vulnerability of the underlying framework.

    I guess this here is just to say: R.I.P., mixlog! You will forever have a place on my backup RAID.
