kfihihc··on A developer's view of Vision Pro
Thanks. If we could have an IMAX-like experience, that would be fantastic.
kfihihc··on A developer's view of Vision Pro
If you wear Vision Pro to watch movies, can the field of view achieve a cinema-like effect. Or can we have a movie theater viewing experience on Vision Pro?

kfihihc··on Show HN: Port of OpenAI's Whisper model in C/C++
It's very cool, I love the talk.wasm example.

It looks like it will open a new application scenario for low-performance hardware products.

kfihihc··on NASA selects SiFive and makes RISC-V the go-to ecosystem for future missions
StarFive announces new JH7110 SoC and SBC based on SiFive U74 CPU core[1].

You can experience SiFive's product in the real world.

kfihihc··on M60 – Open-Source USB&BLE, Hot-Swappable Mechanical Keyboard Powered by Python
You can find more details about M.2 Module here: https://makerdiary.com/collections/frontpage/products/nrf528...
kfihihc··on M60 – Open-Source USB&BLE, Hot-Swappable Mechanical Keyboard Powered by Python
M60 is compatible with MacOS, even media keys.
kfihihc··on M60 – Open-Source USB&BLE, Hot-Swappable Mechanical Keyboard Powered by Python
You got the point :)

Hoping you will enjoy M60.

kfihihc··on A hand-wired USB and Bluetooth keyboard powered by Python
Just for fun :)

The hardware includes a QSPI flash which presents as an USB storage that stored Python source code, and you can modify Python directly.

BTW, It provides a new way to validate your hardware product ideas quickly.

kfihihc··on A hand-wired USB and Bluetooth keyboard powered by Python
The best usb keyboard should have 1ms latency due to USB HID interrupt interval. 4 ms is not that bad.
kfihihc··on A hand-wired USB and Bluetooth keyboard powered by Python
It is a bit slow. It takes 4 ms to scan the matrix once right now. With some optimizations, it may be faster.
kfihihc··on Using Web Bluetooth to Communicate with Bluetooth Devices
If someone want to try Web Bluetooth, please look at this project[1]: a Web Command Line Interface via NUS (Nordic UART Service).

kfihihc··on The curious case of the Raspberry Pi in the network closet
Well, Co-founder of Makerdiary is here :)

I love this article, and I wanna promote our works in this thread :)

We are build some little Nordic nRF52-based widgets for maker with a lot of documents, you can find more wiki at here[1][2]. And we are try to use MESH network technology to protect our IoT data, here is some tutorial for BLE MESH[3] and OpenThread MESH[4].

BTW, if you are intersted in FIDO U2F security key, please check here[5], an open source FIDO U2F implementation on nRF52 SoC.

kfihihc··on Ten days in Shenzhen
I come from Seeed, hope you enjoy the Shenzhen Maker Map :)
kfihihc··on TensorFlow on a 256K RAM microcontroller
It seems Microsoft has another ML library[1] for MCU.

kfihihc··on Discover the world of microcontrollers through Rust
I like TockOS too. As a hardware product manager, I look forward to use it in next project.
kfihihc··on The End of Arduino 101: Intel Leaves Maker Market
How do you think particle.io?
kfihihc··on The End of Arduino 101: Intel Leaves Maker Market
>>IMO, the biggest problem is software startups unwillingness to hire other types of engineers.

>>It's easy to bridge from Arduino to Atmel AVR IF you know how to do board layout. Startups need to either grow their knowledge of electronics or hire some electrical engineers.

I agree, hardware can not agile like software is. So you have to re-design your product from prototype(like Arduino).

Even more, you should outsource your hardware design to other professional hardware company, such as design house.

kfihihc··on On Chinese Writing: Evolution
That would be terrible.

There are[1] short story write with hanyu pinyin(a latin alphabet system) which all words with the same pronunciation.

kfihihc··on Astronauts enter China's space station [video]
Yes.
kfihihc··on I want a USB microphone for my Raspberry Pi, any recommendations?
This Microphone Array (will?) support Raspberry Pi:

kfihihc··on The ESP32 has been released
I think Wio[1] is good choice to getting started. :)

kfihihc··on The ESP32 has been released
There are a Windbond flash onboard, pic is here: https://statics3.seeedstudio.com/product/2016-09/7.png

Some description above the pic:

          • The size of ESP-3212 Wifi module is 16mm x 24mm x 3m.

          • The ESP-3212 deploys 4MB SPI Flash with WSOP-8 package. It also uses 3DBi PCB antenna on board.
ESP3212 is an module, ESP32 is the chip.
kfihihc··on The ESP32 has been released
You can preorder an ESP32 module(with 4MB flash) from SeeedStudio[1] right now.

kfihihc··on ReSpeaker – Open Source Voice Development Board with Microphone Array
Yes or not.

It can be built as an Amazon Echo clone.

But the most important feature is that you can embed it to your product/object but with advanced voice technology, such Far-field Voice Capture, Beamforming, Acoustic Source Localization, Nosie Suppression, De-reverberation and Acoustic Echo Cancellation.

And also it contains a lot feature, such touch, Arduino compatible, expansion header pins, etc. So if you want to build a funny toy instrument, ReSpeaker should be good choice. Or embedding ReSpeaker into a robot which you can chat with.

Besides, it's easy to develop another hardware module motor driver.
