Marvin: Now live on Kickstarter (Until December 3rd, 2016)Marvin is a development board based on the Arduino Leonardo and is grove sensor compatible. We designed the board as a USB (2.4 mm thick pcb) so you can plug it in both your laptop and powerbank...

前段时间自制了一个电容表，虽然我能力有限但是非常喜欢DIY，所以也想展示下自己做的这个小制作，自己一个人搞也没人交流，做出来也没人愿意看实在没意思，在专业人员看来我做的东西都是垃圾，我也实在没办法，我初中都没毕业，用到的技术全都是靠着爱好自学的，由于水平有限也没电容表或者电桥对比，只有几个电容也不知道标准不标准，我不懂模拟电路，这个电容表电路量程切换和放大部分采用许老师的设计，去掉后面的带通滤波和模拟监相部分，直接采用两个ADC口同步采集，程序是我自己写的，我做了下面这些更改，单片机采用2元的STM32F030F4P6，10K正弦波采用软件生成100点正弦表，定时器输出SPWM，每个点触发一次ADC采样，采集100点，因为ADC只能采集正电压所以打开反相再采集100点，上臂下臂分别采集两次，一共采集四次合成两个完整正负电压的表，再用软件生成一个100点正弦和余弦表，把前面生成的电压表的100个数据分别和正弦余弦表里面的数据相乘，再把200个和正弦余弦表相乘的结果相加，100个和正弦表相乘累加的是虚部，100个和余弦表相乘累加的是实部，上面其实就是DFT算法，全部采用定点计算，得到上臂实部虚部，下臂实部虚部四个数据，下面公式计算：100×((−1287−458i)÷(277−813i))  100是下臂电阻阻值，-1287是上臂实部，-458是上臂虚部，227是下臂实部，-813是下臂虚部分等于：2.149253489−159.034862505i...

These LiteOn LTP2558AA LED modules came from the local surplus shop (www.elliottelectronicsupply.com/featured/liteon-ltp2558aa-ra-large-2-4x1-5inch-dot-matrix-red-orange-and-green-leds-gray-face-with-white-dots-in-off-state.html). They have a LOT of...

An Interpreter, for C++? Yes. Despite it's widely known that C++ is an AOT language, such an amazing thing as a C++ interpreter does exist. It's cling developed by Root Team of CERN on the top of LLVM and Clang. You may have played with some toy-like...

Changes I'd Make: Mess around with the bitrate and other image quality settings to try and boost the image qualitySwitch out socket.io for regular web sockets. I used Socket.io because I had experience with that with Flask, but I think as a whole it's...

I've been working on this turret off and on for over 5 years. I hit a huge milestone on May 29th 2019. The turret successfully tracked and shot down a Tiny Whoop (micro drone)! The next day I set the turret up in my living room and captured some footage...

Arduino Motor Shield PCB V1 | 4 Motors at Once Hey guys, welcome back. In my previous post, I explained what an H Bridge Circuit is, L293D motor driver IC and piggybacking L293D Motor driver IC for driving high current motor drivers. In this...

Menopause, also known as the climacteric, is the time in most women's lives when menstrual periods stop permanently, and they are no longer able to bear children. Menopause typically occurs between 49 and 52 years of age. Medical professionals often...

Why reverse engineer file formats?Besides the fact that binary file formats are so last century, people use version control more and more to keep track of design document changes . Rationale that text files are big is very weak, as you could just zip...
