The internals of the AUV performed the heavy work of actually taking water quality measurements and controlling the submersible's buoyancy. Evidently, it also required a sophisticated mechanical design to fit the necessary components into the confined...
Time to think inside the box...1. Flash ATtiny without CALIBRATION defined ( see step 4 )2. Verify everything works as expected3. Assemble project box and solder connectors.\(^_^)/ DONE !
1. Cover the cell with Thread to make it bit not ugly.2. Place all the components on perf board before soldering to make sure everything fits under the board size.3. Solder NE555 ic with other passive components including the tactile switch, then solder...
Now you can put the NTS-1 board back in place to test if everything works. The red wire than goes inside should be placed in the empty space on the top-left side of the board, as pictured here. Before going any further, it's time to test if everything...
The first thing to do is to get rid of the 1/8 jack that came with the sensorThen I put some soldering in the end of the cable so it can be easy to stick it in the protoboardConnect everything as the the Fritzing Diagram suggestDownload the Arduino Sketch...
Buy everything from the materials list from Aliexpress. Try to group your purchases under one supplier as this will lower shipping costs. Get a case that is at least 9 x 7 x 3 cm, this is just large enough for the half size breadboard.Store all components...
You will need: - Male to Female jumper cables - AVR programmer ( I used Pocket AVR programmer from sparkfun ) - USB micro cable for the programmer -USB OTG cable -All 3D printed parts -M3 x 10 CSK screws -Silicone button pads
Add solder to one pad, use pliers to hold the hin in place and solder everything together. After that use heat the second pad and the clip simultaneously and add solder to fix up the second pad. You need to start with the clip because it takes a lot...
I tried to label all the parts on the PCB and everything lines up so it should be pretty easy. If you're having trouble soldering the pins on the flex connectors, get a better iron! I upgraded to a fx-888 and my soldering time for the board went...
If everything worked correctly you should now have control of the movement motors and end stops. Manually move the print head to the center of the printer. Next, the axes homing will be tested to ensure the motors are wired up correctly. Be prepared...
