Browsing through Aliexpress, Ebay and some other retails market to mass sell is showing more and more product to lower in price ...
Starting by opening a core. In a recession something that cost like keeping PIC architecture for your and limit development to some environment make some product to switch to open platform to maintain their product to a lower price. The core is still unknown , but from brand like expert using Aufero and seeing it in many technical exposed, Aufero is recently reporting using S2 Expressif core, as some DIY engraver tools using simply a Arduino Nano like infrastructure, with simple 328p MCU processor.
Doing this recently after a declaration of Biden in investment of 400 millions in schools and affiliate during Pandemic do include providing top tools to a lower price including way to promote self learning across modern way it's Microsoft, Intel dream and maybe Arduino reality . Well I do shop my schools part to go back end my Technical Lab course and Shall I Should be wrapped out by Politic Science, it's not suppose to be a scavenging world. And for the course I do shop across retail market and found my oscilloscope for 35$ and it's an STM32 with 64k of memory, the WAINLUX K6 bought with default Bluetooth can possibly be an Espressif C3, with self bluetooth and some previous story with perfect companion is a S2 to a Arduino docking situation, but Espressif C3 is barely available in development board since less than 2 years but have probably be reserved for this kind of infrastructure.
Coming next image of the C3 itself bought during October it's aliexpress favorite and are available around 3 or 4 Canadian dollar only... And it can be a core of a drill, engravement, laser cutter, and about the price of the widget, WAINLUX K6, 206$ not much .
You are not going to ask yourself some other details like :
- If you visit the "Canadian Money Hotel" they teach you the dollar plate is engraved with laser for all plate that design money and are made from a 15 to 20 watts entry laser and produce 3.5 watts of light for engravement of our Queen to our bill ...
In fact it's exactly about the same laser toward description left. And the awesome reality of those Liberal who are afraid to leave such tools to a lower price have embedded a under reality, it can only engrave 8 cm by 8 cm, and if you are trying to make your own money out of that process, calibration is a required work to achieve you task, as Number left on the bill too is the Database of number for a bill and it's uniqueness is unlikely it's only one value. So it's twice a goal to work with a matrix approximately 300 to 350 dpi in a 3.14 inch wide... So it's twice afraid liberal to says I'm going to deal with few more trick to work with a MEGA2560, or DUE pcb form factor to assemble like RP2040 or Expressif with a lot of electronic compound, like gps, card reader and so on ...
Another details about money it's the weight and the puncture mark calibration that change upon the detail on the money to keep a steady weight and steady electric reading calling reactance based on metal structure of coin. It's also use the laser of the same level to achieve correction of the puncture mark.
As they say it's household uses and many project to design from paper sheet density ; can only fit in my goal. Like designing a cellular sheets after sheet make possible to call for hybrid compound, you cover it out with HDPE and it goes into production because the shelve. Designing extremely flat drone which they will bring into sub air to space after being shoot like freebee, and do use counter force of kinetics to avoid gaining heat...
As well it report household use in engraving epoxy or so called corn heated powder and ethyl epoxy and pressed it turn into friendly low grade cardboard, and may be more suitable than epoxy/(amino fiber glass) from retail market, but it do have it's ability for engravement but stronger in case of fiber glass. I am sure coffee cup will it's genuine prototyping see about everywhere it's dextrose and wood .
