My circuit is run by a single 12V 5A power supply. A L298N H-Bridge that I had in spare converts 12V in 5V and provides this as input to the ESP8266. This allows me to easily switch on/off the ESP8266 and the stepper driver by a push button. ...
It helps to have the wooden arc clamped sideways to a table for this part. Insert the LED wires into the top of the case and the wooden arc in too. Add the clamp piece to the back of the case and bolt together with the M4 bolts and nuts (inserted...
Here is a schematic that you can use to connect your development board to the motors and drivers. As you can see there are quite a few cables and it can get quite messy if you try to use a breadboard. To solve this I developed a custom PCB to handle...
Note: In schematic wiring drawings, the wire lines are drawn from one hole on the shield or protoboard to another. The wires connecting these holes should have the insulation stripped from their ends, and have the bare lead inserted into the hole. The...
Lexitron circuit design and hardware:LED display: The display is constructed using Red 8x8 square LED matrix displays, each containing 64 LEDs wired in a square grid with the 16 column and row pins available out the base. It is designed to be used in...
The fourth module (as one can tell), is hardware-oriented. The XML config shows that the driver is for a Texas Instruments dev board. This also means that the IDE that the fourth component was developed on was likely CCS Cloud. Now you may be confused...
The USB portThe SF02/F ships with a mini-USB port that can be used to enter settings into the unit. You can actually run the SF02/F from this port without using a power supply but for this project I’ll keep the power supply connected so that both the...
To find optimal speed of LED pulse transmission that depend on your setup and used component I suggest you first build simple but fast and effective LED driver.I suggest this design, and as you already read from presented papers I tested under real work...
The switching circuit is relatively simple, but you have a few options for features to add to it. At its heart, the switching circuit is simply a circuit that allows voltage to flow when the output from the triangle wave generator is above v_feedback,...
Make sure that jumpers on the TI CC3200 LaunchPad board are mounted as follows: * J2 in short * J3 in short * SOP 2 in short Connect micro USB to the TI CC3200 Launchpad board and to the PC Open the UniFlash tool, and make a new configuration by choosing...
The yellow trace is the FIRE_N signal that triggers the laser driver circuit on the falling edge. The red trace (LeCroy has their own idea as to what red is) shows the return signal after the comparator. The time scale is 50 ns per division. The first...
Now this is the most interesting part of the whole build and the hardest part for me to get working. So in order to hear voices from the sparks I have to run it at constant wave mode which just means the mosfet is on a lot of the time, which translates...
Starting with the HDMI switcher. I desoldered the existing switch and extended the pins on the board with 6 wires. Most of these things have an OnOn (DPDT) switch, which means you can't just leave it in place and extend connections. Next I soldered...
CHRP4 can be built in three major configurations: Educational starter configuration – a beginner USB-C microcontroller development board with on-board pushbuttons, LEDs, and a piezo beeper. Learners can complete all of the introductory learning activities...
