Hey #FediHire , meet @Dominicd3213

He's an embedded systems and #fullstack #developer who loves making machines move and websites work. By day, he wires up #Robots with ROS 2, #arduino and LIDAR; by night, he wrangles #react#TypeScript and #MongoDB into sleek, responsive interfaces. Built #AI chat tools, and co-founded a trading platform.

He lives where code meets circuits, and believes great tech should be powerful and weird.

Anyone need a bright young guy like this?

#Developers

​It is done. I finished making the CNC machine. It draws circuits on a copper plate, just how i wanted. It is rare for me to finish a project. I'm so incredibly happy about it
The machine is still in kind of a rough shape. I will make proper power circuit and maybe a bluetooth for serial. Other then that, it is ready to be used

(Part 7: Finished)

Update on the bed thermostat:

It mostly works really well, but today I've redesigned the sensor housing and placement so it can be away from wild swings in temperature (It could probably use a fabric sleeve to protect the wires.)

I might also need to finally learn how to print TPU, so I can extend the airflow further into the bed.

Most of the project is here: https://github.com/b73tt/bedcooler

Okay I'm so incredibly excited to show this The CNC machine is almost ready and here is a short video of the z axis at work, together with a 3d printed pen holding contraption (courtesy of my friend who kindly printed it for me 🥰)
I can't believe it works. Now all that remains is the software part 👀

Meshcore is working well enough in Seattle that now adoption is the largest issue to having a more robust LoRa mesh network.

So if you're in the PNW area and want to build a solid handheld LoRa radio to try out meshcore I've made a bill of materials for my go to portable build LoRa plans.

Wiring placed on a prototype board. Both axis move!
I've run into problems initially, because the second chip wouldn't work no matter what I did but i finally found the issue. It was because arduino nano i'm using, specifically it's pins A6 and A7 𝗮𝗿𝗲 𝗮𝗻𝗮𝗹𝗼𝗴 𝗼𝗻𝗹𝘆 and to drive those chips, you need a digital signal. It took me an embarrassing amount of time to figure out and an unnecessary disassembly and assembly of the board. Hopefully this post will save somebody some debugging

(Part 5)

I've got movement!
I roughly connected one bridge to one axis to see if it would move at all and look at it! Look at it goooo
I feel reinvigorated, I think i might actually be able to finish this project. Next up is putting all the wiring on a prototype board

Also have you seen this neat little #OpenSCAD program that you give it a list of screw hole locations and it automatically generates a 3D printable PCB mounting frame baseplate with standoffs? It's really slick!

(What do you mean "No, because you forgot to share it before")

Jamming everything inside was a little tight. Maybe I'll rebuild it and see if I can get things to fit better. #Arduino#ESP32 #electronics #maker

The box is the same form factor as the temperature controller I slapped together at Christmas. The back panel is nearly the same, but the cord socket has a built-in switch & fuse. #Arduino#ESP32 #electronics #maker

Got my little "fan controller" built. It's just an ESP32 with a relay board controlling a couple of outlets. It subscribes to MQTT and receives commands and sends status. Buttons to toggle outlet state, LEDs above buttons to indicate state. LEDs along right are power, WiFi connected, MQTT connected.

Just before bed slapped together Python script that runs on my server to monitor bedroom temp and outdoor temp and keep room comfortable without A/C. It worked!

The axis are now mounted. This project just flooded me with dopamine initially, but with all the annoying problems i had, it got frustrating. I had trouble leveling and angling the axis correctly and the metal plates were a nightmare to drill holes for the screws. I had to obtain harder drills but this step was eventually a success. Next up is wiring the electronics

(Part 3)

#diy #cnc #arduino #electronics

The scaffolding is ready, just like in the article, i found that the leftover metal chassis is perfect to be reused for this. I welded the vertical sheet using just a soldering tin with welding paste since i don't have a welding machine. It's a silly way to do it but it holds solid. Quick tip, use rubber bands to mark straight lines (see pic) when placing measurements.

Of course by the time I almost got it working the temperatures were already within 5 degrees. #Pushover#Arduino#ESP32 #electronics #maker

Time to cobble together a quick & dirty Python script that can monitor the outdoor temperature and the indoor temperature and when the difference reaches 5 degrees have it send a #Pushover notification to my phone to turn off the whole house fan. #Arduino#ESP32 #electronics #maker
