Downloaded the image from Aliexpress and asked ChatGPT to write me a snakeoil advertising text.
With the ever increasing number of accelerometers sold it's time to finisch something that has already been on my development shelf for some time : a test rig for controlling & testing newly made StarBass 54 accelerometers.

We're taking a break for the next 5 weeks trying to focus away from chips, 0805, 0603, SOP8, SOT23, clingon's and starbasses visiting wonderfull Thailand to meet my oldest son parents in law, travel at least 2000 mile, sample local cuisine, attend a marriage and see temples while thinking it's way too hot in here and will be back for business from 15 august onwards. Happy Holidays to you all !

The first 2020 TPA3255 based BMH3D module prototype got initially halted due to thermal problems but thanks to some nifty CnC work done by a fellow maker I was finally able to get it working properly. After extensive testing including late night listening sessions the first 2023 version is here and altough still in it's prototype phase did receive some notable improvements over the 2020 design among which are the increased VDD buffercapacity and the usage of larger reconstruction filter inductors.
A batch of five has been ordered which will be tested mid august after our holiday break.
Scroll down for what it returned, a bit cheesy using phrases like redefining boundaries, immersive and captivating audio experiences, commitment to innovation and synergistic relationships but hey, they are Microsoft nowadays so I guess I could have expected such Lingo ...
Greetings from Amsterdam,
Allow me to introduce myself. I am Chris Camphuisen, a passionate manufacturer specializing in the world of motional feedback loudspeakers. With a firm belief in the pursuit of audio perfection, my journey has led me to design and build cutting-edge audio systems that redefine the boundaries of sound reproduction. Today, I am thrilled to launch this blog as a platform to share the latest developments in my work and keep you, our valued customers, informed about our exciting advancements.
At the heart of our work lies the concept of motional feedback, a technology that brings a new level of accuracy and control to loudspeakers. By integrating accelerometers into our designs, we are able to precisely measure and monitor the motion of the speaker diaphragm in real-time. This data is then used to provide immediate feedback to the amplifier, resulting in unparalleled accuracy, reduced distortion, and improved transient response.
One area where our expertise truly shines is in the realm of servo bass systems. We have dedicated significant research and resources to develop accelerometers specifically tailored for this purpose. These accelerometers, combined with our multichannel amplifier modules featuring analog crossovers and loop logic, create a seamless integration of high-fidelity sound reproduction and precise control over the low-frequency range. The result is a bass experience that is tight, articulate, and faithfully reproduced, enhancing your overall listening pleasure.
But our commitment to innovation doesn't stop there. We are also exploring the synergistic relationship between servodrive woofers and magnetic planar loudspeakers. By harnessing the strengths of both technologies, we aim to deliver a truly immersive and captivating audio experience. Through extensive research and experimentation, we are unlocking new possibilities in sound reproduction, with the goal of providing you with a level of audio quality that surpasses your expectations.
This blog will serve as a window into our world, where we will delve deeper into the intricacies of motional feedback loudspeakers, discuss the technical aspects of our designs, and share the latest updates on our ongoing research and development. Our passion for audio excellence drives us to continuously push the boundaries of what is possible, and we look forward to sharing our journey with you.
Thank you for joining us on this exciting adventure. Together, let us embark on a sonic exploration that will redefine your listening experience.
Stay tuned for more updates!

With our Little/One being all Grown/Up it's time to start the enclosure design for its First/Love. Shown are the early prototypes using vintage philips drivers. For fun :-) Its 4BMH6D amplifier prototype has been succesfully tested and offers enough power features to satisfy any first/love desires.
