Seeed Technology Grove, Sensor, Ultrasonic 101020010
Seeed Technology Grove, Sensor, Ultrasonic 101020010

5.0 out of 5 stars Just works, 3 Jan. 2016
Using the example python script with the GrovePi+ shield on a Model B+ Raspberry, this module works 'out of the box'. No additional configuration of the GrovePi environment needed. You get a reading from the sensor which is probably in cm and is very sensitive. You can hear it clicking if you listen very carefully.

It's a nice quality mouse for the price. It is definitely silent but the instructions are in Chinese and German! I haven't yet figured out what pressing both buttons does - it seems to have a function and there's a clickable central (led?) light. Maybe I'll find out in time.

1.0 out of 5 stars Faulty level shifter on TX IO, 13 Jun. 2015
Verified Purchase(What is this?)
Doesn't work with Raspberry Pi. Confirmed as not working by testing with the serialtest.py program. Of course It'll cost me more to send back than the cost of the item. Which is exactly what the manufacturers will be banking on.

Ron's Jamie Oliver 'interlude' had me in stitches and the Stratford Bear episode (with accompanying drawing - just for the kids) was genius. This is the story of (almost) every rural market town teenager's struggle.

5.0 out of 5 stars Everyone with an inquiring mind should read this book, 6 Jan. 2015

"What if the world suddenly stopped spinning?" is one of my favourites in this book. The short term answer is "everything dies". The long term answer is "everything will return to normal". The full explanation is weird, wonderful, intriguing and is something to do with the moon.

Everyone with children or grandchildren with inquiring minds should also read this book, if only to keep them quiet.

1.0 out of 5 stars Tap leaked and flooded kitchen! Beware!, 31 Dec. 2014
Verified Purchase(What is this?)
Within the warranty period the tap flooded the kitchen. A plumber came to find the source of the leak and within an hour declared it to be the tap. He dismantled it and found that the top of the braided feed pipes are completely enclosed (cannot be tightened) and that the washers provided were the very cheap paper(!) types that quickly perish. Why would a company making a £290 tap do that? I don't know and neither did the plumber. I now have a £70 bill from the plumber, a useless tap and no refund from Grohe in sight!

3.0 out of 5 stars The support is ad-hoc but the TFT shield does work with the right Pi image (see below), 26 Dec. 2014
Verified Purchase(What is this?)
Let's say you looked out of the window one day and thought you'd best tidy up the garden. You need a spade. So you go to the local hardware store. The shop assistant gives you a lead cast, a steel ingot, a piece of hardwood, a schematic for a spade design and says that there are some poorly written basic instructions online somewhere. You thought you were going to the store for a spade but got this. Your garden is still overgrown and you're kinda confused.

This TFT screen is much like what you get if you chose to take up the hardware store's spade offer. It comes with no drivers or any support from the manufacturer WaveShare (they actually point blank refused online to provide one purchaser drivers, even by email). So you get the board and ... that's it. No manual, no installation driver, nothing. There is a product description available online here:

http://www.wvshare.com/product/3.5inch-RPi-LCD-A.htm

But that's everything. No drivers or support offered.

The central issue here is that this is another fabless product from Shenzhen with no drivers, no manufacturer support and very little public information available. If this kind of adventure is what you want of this product, it's ideal.

Personally, I just wanted a working TFT screen for my Pi because I've got other stuff I need to do with this.

** UPDATE **

ZX3 Tech's support sent the following to me shortly after I quizzed them on the lack of drivers or support CD from WaveShare:

---------------------------

Sorry !
The link for Driver for raspberry B+
https://mega.co.nz/#!JAVgCQxQ!WchLJQfijwnJcVUMlk466AsD6UQ0WQspO3LWlDNqAG0

---------------------------

That image does work and it is safe to rpi-update and apt-get update/upgrade as it does not appear to use out-of-tree patches. It probably uses very standard drivers with a particular GPIO setup but I haven't investigated exactly what it loads yet.

1.0 out of 5 stars Not production ready, 12 Aug. 2014
I've tried three of these devices and all seem to have the same issue. It is a very technical problem to do with how the device authenticates to wireless networks. I'll delve into the detail later.

The first one I tried was actually a pre-release - before the device was officially supported in the UK but available through third party sellers on amazon.co.uk. I was very hopeful of the potential of this device for a number of reasons - google generally spends a lot of time focusing on solving problems with good quality, well tested products.

The first time a product fails, you dismiss it as unlucky. The second time it happens you start reading the manual. The third time you start questioning whether you have one of a duff batch. When the Chromecast goes wrong, it comes up with 'kooky' error messages. But just like personalities labelled as kooky, they are fun the first time but *really* irritating later. So seeing an unhelpful error message saying "NATCH! Something went weird - sorry 'bout that!" is not even vaguely funny after the 30th time.

Now to the precise nature of the problem. Wireless network cards come in a few flavours but most have the capability of running in two modes - 'active' and 'passive' ('monitor') mode. When the Chromecast fires up, it runs in monitor mode, passively scanning for available networks nearby. Then, when you choose a network in the on-screen GUI, it switches over into active mode to actively connect to the network of your choosing. The problem with all of the Chromecasts I have tried (and all sent back) is that very few wireless devices can do this changeover reliably and the Chromecast is no exception. This results in the device not being able to authenticate correctly on the network or simply losing connectivity during operation or on startup after initial configuration.

And it's not the network at fault - I've tried three of these devices each on three different networks with different encryption levels set - each has intermittently connected, but unreliably. Initially I was told by a number of users that this was probably a faulty batch but I've tried a number of them and they all have the same problem. If you know hardware though, you'll know that finding a network card that does passive mode (or packet injection) reliably is a struggle if your budget is low. I'd guess the network card in a Chormecast will be at the lower end of the budget spectrum for the price you get it so this should not be a surprise.

So in conclusion, you do get what you pay for and this product is very cheap.

It would be better if the SOS button had a 'cancel' function but it's easy enough to use.
