After disassembling the device a visual inspection of both components and traces was conducted, however there were no evident signs of failure (i.e. scorching marks on the PCB, bloated capacitors, charred resistors, etc). Because the machine wouldn't...
So the last power distribution board I made was a bit of a mess to say the least... It worked, but I really wanted to make a proper PCB. That way, it wouldn't look so janky, I could getter better current flow, nice mounting holes, and get a place to...
Interactive and immersive learning CRUMB offers an easy to use and interactive introduction to electronic circuitry. Fully realised in 3D, you can construct prototype circuits as you would at the workbench without the risk of terminal component failure...
Tools and materials used: Raspberry Pi Pico1602 LCD display (w. i2c backpack)breadboards and soldering ironperfboard, w. 22awg wirelevel shifter module (only using 2 out of 4 lines for i2c)two 3x4 and one 4x4 aliexpress keypads (modified to jam as close...
All the STL, STEP, and FreeCAD files can be found on GrabCAD.The rolling block trigger is one of the key features of this design. The size of the rolling block makes for a very strong string catch, while the trigger design allows for the easy inclusion...
TL;DR Design not only the firmware, but also the schematic (netlist), PCB, and case all in Python.Mainly introduce the design flow (please read the documentation and source code for the detailed)The code will be explained in a runnable jupyter notebook...
Building your vehicles will be a personal choice, but here are some things I found useful. Use nylon standoffs and nuts and bolts where electrical components mount to metal. Clean and repaint any old Meccano to remove the lead paint. A quick hot...
To keep cost and weight down, it's essential to make the floor as compact as possible. However, LED diffusion is in direct competition with this goal. The surface of the dance floor will be 1/4" semi-opaque white acrylic. If the LEDs are right up against...
Thank you to PCBWay for finding this project on here and offering a sponsorship! A majority of the cost of this revision, including the boards, components, and assembly, are paid for by PCBWay. Saves me a lot of time placing the components by hand! ...
Some picturesHere is the disassembled device (guess the age of the green 10k resistors): ... and here is the circuit: Here's how it looks assembled (I was too lazy to draw the labels, so I delegated it to the 3D printer): And here is an example of my...
An attempt was made at a multi part PLA mold for a stool. The clay actually holds the mold together so it doesn't need a lot of PLA. After failing to dry at all on the print bed, the decision was made to sacrifice the PLA in the oven. ...
Made a vijeo of backflow incense. It seems the clay doesn't dry at all unless it's taken out of the mold. The mold needs to have flanges to grab on to. It needs panels which don't require a sheering force to take off. The holes...
A custom PCB is a nice feature to move from the protoboard to reliable connections. My goal is to make a nice small and space saving PCB. Thus, I will not just plug breakout boards to their headers on the PCB but will solder them directly to the PCB....
This low-power ePaper display automatically joins a long-range wireless network and displays weather information, along with arbitrary data entered from the browser interface. Messages are automated for regular updates from a NodeJS/React server. In...
Hey! Remember that epic 3D image I showed you a while back? Well, guess what? I finally got my hands on the real deal! I ordered the components and the PCB of this awesome Openthing 1 ESP-CM3 Programmer Board, and it arrived yesterday. It's the...
