For Emirator, it is often encountered a very interesting question, "Do one, or buy one". For ordinary people, of course I can only buy one. For the Emirator, as long as you wish, you will do it yourself. In general, because of the quantity production of electronic products, the cost of doing one can be more expensive. But the pokers are generally not careless, they care how to make things out. There is a little brother, he is originally planned to buy a scientific calculator, but finally DIY is one. Among them, the processing of the calculator is the Raspberry Pisero. The housing of this calculator is 3D printing, and the PCB is customized, and even the calculator program is herself. The PCB of the calculator is connected to the IO port of the Raspberry Pie. The button is completely 3D print, but unfortunately no tags are printed on the button. When the calculator is actually used, it is close to the blind, because I have to guess what the button is, so I will see it, this calculator has only a little brother. A lithium battery is installed in the calculator and is arranged in the charging management circuit; allowing this calculator to be used. In this picture below, you will find that the SD card interface is outward. This is a relatively convenient design. After the back cover is covered, you can still easily replace the SD card. The calculator's program and the RBB share on the SD card, and the different SD card is equivalent to replacing different calculator firmware. The project of this Raspberry Science Calculator is now open, and the small partner who wants the project information can leave a message.
