The open communication robot for everyone In recent years, a variety of communication robots have appeared on the market. However, most of them are "closed", dependent on specific proprietary services, or their specifications are not disclosed...
* * OVERVIEW * * Studio 68 is a board to make retro-computing "experiments". It has a 68SEC000 CPU, a STM32F030R8T6 MCU + USB + SD, a 16MWord SDR DRAM and a 208pin FPGA. So It is possible use an approach based on virtual HW emulated using the STM32 MCU...
500W Power Inverter With Reverse Polarity Protection Hi friends. I have TG500 UPS but it have some problem so, i use it's transformer, mosfet,diode,capacitor for make new Inveter. I hope you like it. In video below i show you how to make 500w...
I did a quick test with a laptop(Putty) and Arduino in the vehicle and was able to to get OBD info, so I guess the connections are fine. And the 1996 Ram even started afterwards. I added some new handling for 'SEARCHING...' after this. Looks like there's...
This board is part of Fyber Labs Flex Module project.Flex sensor input to ADC will be essentially DC voltage so filtering isn't critical. The buffer provides uniform impedance and somewhat linear use of the 0-3.3V ADC input for the resistance range of...
The selection of the feedback resistors is critical. The standard output voltage is supposed to be 3.3V. For the appropriate resistor values i just checked the datasheet which had a table with values. Since the I want to be able to select the output...
This board is part of Fyber Labs Flex Module project.Biopotential signals are low frequency small voltage output that need very clean power and low cross-talk routing.Example signal types(source): EEG:Surface 5 mV 200HzScalp 300uV 100HzEMG:On skin 10...
The delta uses KF-m 3 airfoil and it is optimized to fly slow while carrying a payload. It flights for 40 minutes with 2 2200mAh LiPo batteries. A video of the delta flying.I got a lot of help in the RCGroups forum and now I need to create a thread for...
Note: This project assumes you have Arduino IDE setup and know how to connect and write to an Arduino Uno board. Hook Up Your Servos The first step is to hook up your servos to your UNO. If you purchased the same servos I used from Amazon the wires...
From OpenCores PDP-8 page: Features In this FPGA implementation, the PDP-8 CPU can be configured to emulate the instruction execution of a PDP-8 (Straight-8), PDP-8/S, PDP-8/S, PDP-8/I, PDP-8/L, PDP-8/E/F/M, PDP-8/A, HD-6100, or a HD-6120. The...
Lora AC Dimmer chopper circuit is based on Triac BT139, and zero-cross checking circuit, it detects the zero-cross points and then the Triac controlled to chop the AC. Besides, to avoid the problem of AC can not be totally shunted off with Triac, a relay...
As low-cost desktop 3D printing is now dominated by free and open source self-replicating rapid prototype (RepRap) derivatives, there is an intense interest in extending the scope of potential applications to manufacturing. This study describes a manufacturing...
KeypadAdding a 12 key keypad (0 to 9 with * and #) requires seven i/o pins. Each switch connects one row wire to one column wire. Connection scheme used in the test code is shown below. 300 ohm resistors protect the outputs from short circuits when multiple...

Onboard Programmers are great On microcontroller development boards (such as ST Nucleo Boards) it's very handy to have an integrated JTAG programmer/debugger. If you would like to build your own board with an embedded programmer, things get a bit tricky.In...
