Very good product for its price

For HB100 Doppler Speed Sensor - Arduino Compatible

I used this sensor in a university project with a group of people not very familiar with electronics and programming and it worked just fine. It is not perfect for measuring speed, but functions well for its price and is relatively easy to use.
Buying experience was excellent - seller answered my questions quickly and product shipped in a speedy manner.

Really fun and practical

For The Whistled - A Whistle Detection Device

Mine took 2 month to arrive thanks to the precious chilean postage service. I had to modify the power supply as the legs didnt properly fit the electric socket but after works like a charm. You need to whistle loud and strong in order to activate it and the dimmer works great!

Good product!

For HB100 Doppler Speed Sensor - Arduino Compatible

I had bought some bare HB100 sensors before, just to see the IF output on a scope. This module, with an amplifier, gives a good understanding of how the output can be actually used and interfaced with a microcontroller.
Many thanks!!

I love my Mooltipass

For Mooltipass Cards & Holders

The Mooltipass is convenient to use and as safe as it can get. I'm using it every day and it just works. Also, thanks for selling the cards at that price.

Hello,

Thanks a lot for your review! Please note we're about to launch the Mooltipass Mini, and that your cards will still be compatible with it.

Need help

For HB100 Doppler Speed Sensor - Arduino Compatible

Hello i have read the documentation and i think the high pass filter is to low
I would to make car speed mesurment and the velocity is 60km/h.
Your filter is designed for 72hz?
Thanks for your reply

Hello,
Actually if the sensor is right in front of the car you'll be able to measure high speeds. Have a look at this web page for reference:

Great little gadget

For The Whistled - A Whistle Detection Device

Pretty good gadget. Sometimes gets triggered by mistake, but I control only small light so it doesn't bother me.

Neat product, well designed and documented :)

For HB100 Doppler Speed Sensor - Arduino Compatible

Nice quality item, well designed, with a nice form factor. Its (online) documentation is pretty good and I must thank its designer for his careful help and advices using this product.
Packaging was just fine.
In short: I would (and already have) recommend this product :)

awesome product but a bit expensive

For Mooltipass Offline Password Keeper

I really like the product but at the price point, it makes it more of a business tool. (how important is the data you are trying to protect?)

Mooltipass is a must have!

For Mooltipass Offline Password Keeper

With the dawn of technology and the rise of cloud computing, passwords are quickly becoming insecure. With dictionary attacks that go after your loved ones and interest to crack those easy to remember passwords, and brute force hacks that attack those long and difficult to remember passwords in less than a day, it is becoming more and more necessary to have some form of password store. Keepass however requires you to keep a local file that could get outdated and might not be on your pc. Put it on dropbox? That's like giving all your passwords away for free! Its only a matter of time before its intercepted and cracked. What about one of those fancy online tools like onepassword? They are susceptible to the keeper of the keys problem: the hackers are going straight for the managers because they're an easy target.

So one is left with a concern for what the right answer is. With Mooltipass, you can now store those long passwords (even have the device make them for you) while still keeping them out of the hands of hackers. With a 2 step authentication and self destructing keycards, the Mooltipass is not a device that can simply be brute forced. It has all of the functionality and capability of a full password manager, but can also be used like a keyboard and is easy to bring with you. This device has been amazing to use, and I look forward to working with its api to extend what it is capable of! Review Image

Great little board - makes experimenting super-easy

For ESP8266 Wifi Module Breakout, USB, 3.3V, Prog But.

I am really impressed with this little board, it's really straightforward yet has some lovely design touches.

The little breadboard is just big enough and together fit really well.

The lack of through hole components means it sits well on my desk too!

The only tiny criticism is the silkscreen for the header pins is very small and could maybe line up with the pins better?

But overall I'd recommend this dev board 100% for anyone who wants to investigate this interesting chip, nice one Mathieu!

Thanks for the great review!
Funny you should mention the pinout on the silkscreen... I've spent quite some time trying to find a better way, without success unfortunately.
