I think this is a great project for beginning solderers. I like the robot design and I am looking forward to working with these with my students. My only complaint is that they do not come with the battery. I knew this was the case the I ordered but there was nothing indicating which battery I needed to order. Luckily I was able to find an old post for the badge on another website to get the information I needed. I would be willing to pay more if they came with the battery. But overall, great product. Thank you. These are going to light up our school makerspace lab!
The overall quality is very good but it miss some very important information. The design rules are not complete. I still prefer this (my) one (more complete) ;) : https://www.tindie.com/products/sinzu/the-ultimate-pcb-ruler/ By the way, it's look like you copy some parts from this ruler ...
Shipping: it took 3 weeks to receive it from China to France.
I bought assembled cube. Perfomance is good. But I had small problem with documentation. I had to look on Google some description how to connect to arduino board and test sequence of LED for programming. Thank You.
I use this eInk display as test platform for u8g2 Arduino graphics library. Wiring is easy and the display works as expected. Only 4 stars for documentation, because the pin names are missing on the PCB (instead a paper description is included) and the original SSD1606 datasheet seems to be incomplete in some details. As stated in the description: The eInk display requires about one second for screen refresh. All in all a very nice display with great contrast, which keeps the content permanently (also during power off).
I bought the assembled version, which I regret, because the job is not done well. The boards are not aligned well, some angles are visibly not 90 deg. Some edges have gaps. Assembly wires are protruding from the cube. Overall the cube looks beat up. The boards looks fine. My advise would be to buy the individual boards and do the assembly yourself.
It is unclear if the unassembled version means you get bare pcb and some smd components? Or if the pcbs are assembled and you only needs to assemble the cube?
No documentation is provided. You can google WS2812B datasheet, but you have to figure out how the leds are connected, by using trial and error.
I finally got around to using this; I wanted a low power display that doesn't get updated very often (a few times a day at best) and this works great. Quality of the screen & backpack are great. It's clear they do a quality control check before they ship it out. If I need another paper white type screen, I would absolutely get another one.
I ordered a coupe of these to work on as a Christmas project with my two sons. I ordered it on Dec 11, thinking 14 days was enough time for it to arrive. Not only did it not arrive in time for Christmas, it didn't arrive before my kids winter break was over, and as a result we never got to work on it. It was completely inappropriate for Tindie to feature this in a promotional email sent out during the US holidays.
Regarding the item itself, it's a very simple PCB with some self-flashing LEDs. I've soldered it up myself (kids are no longer interested), but since there are no instructions, I have no idea what kind of batteries it takes. I guess I'll have to see if I can figure that out on my own.
