I don't like the colour. Can we have a red one?It's not level...
Hi @TechGirl I'm sometimes a bit slow. Do you and others think this is our chip running the Bosch Sensortech?Rob Telson Likes this........I seem to remember Brainchip comparing our ability with VOC's to sense smells like a dogs nose

Gas sensor BME688

BME688
Environmental sensing with Artificial Intelligence
The BME688 is the first gas sensor with Artificial Intelligence (AI) and integrated high-linearity and high-accuracy pressure, humidity and temperature sensors. It is housed in a robust yet compact 3.0 x 3.0 x 0.9 mm³ package and especially developed for mobile & connected applications where size and low power consumption are critical requirements. The gas sensor can detect Volatile Organic Compounds (VOCs), volatile sulfur compounds (VSCs) and other gases such as carbon monoxide and hydrogen in the part per billion (ppb) range.
Additionally to all features of the BME680, the BME688 has a gas scanner function. In standard configuration, the presence of VSCs is being detected as indicator for e.g. bacteria growth. And the gas scanner can be customized with respect to sensitivity, selectivity, data rate and power consumption as well. The BME AI-Studio tool enables customers to train the BME688 gas scanner on their specific application, like in home appliances, IoT products or Smart Home.

Any one else immediately upon reading your post remember Anil Mankar’s 2021 Ai Field Day presentation where he mentioned that a couple of nodes of AKIDA IP could do “pressure, temperature, low cost things” on a very small device and give all the functionality of AKIDA where latency was not a primary issue.

Agreed, I’m waiting on a small sum of money to come through as well so I know it’s selfish but I’d like prices to stay as they are for a bit longer also!I dislike getting paid fortnightly atm because I have to wait till next week before I buy more BRN shares. Don’t go up to quickly please![]()
Hi @TechGirl I'm sometimes a bit slow. Do you and others think this is our chip running the Bosch Sensortech?
Hi Dhm,
Bosch and Mercedes Benz have a well known partnership so it is suspected Bosch would be aware of Brainchip.

The gas sensor is stated to contain AI so I’m hopeful it contains Akida!
They would be a great partner and I’m sure we could help boost their bottom line!

There was such a big song and dance made about the lackluster ironing efforts made by the Brainchip team last time out. We felt it was appropriate to acknowledge the top job done this time out
