@obob0i made the pcb outline of my hackpad, though it was extremely hard to find footprints for the oled and rotary encoder
@GB1140I was able to rework the entire circuit to make it work as intended. Thanks @Caleb-U0908HR211R .@Eucatastrophe0couldn't sleep so i got up and tried to learn basic circuit board stuff :P
@obob0i made a pcb for the second time! it turns on in the dark using a photoresistor and transistor
@GB1140Have been trying to learn PCB design for the past two days and this is what I achieved and submitted to solder:
@iUnstable00Day 3:
I procrastinated on the neighborhood project again 😔
Yesterday was pretty packed tho. I did more research into Meshtastic nodes and decided to go with Femtofox! Their hardware looks solid, but sadly they’ve got this proprietary “Pro” edition that has extra features compared to the open-source one. Tbh I wouldn’t mind supporting them and paying for the hardware, but they’re out of stock 😭 The difference isn’t that huge though, so I’ll probably just roll with the free version and pay for PCB manufacturing myself.
I also got an automatic water dispenser for my cat recently, and it’s really annoying. It allows only a maximum of one water refill every 6 hours (drains the old water and pumps in fresh), but the waste bin fills up in just 2 days... For something that’s supposed to be convenient, it’s kina not 💀
My first idea was to just manually power it on, press the “refresh” touch button, and turn it back off. But that defeats the entire point, it would honestly be faster to just dump out a normal water bowl and refill it by hand.. So I cracked the device open, soldered a wire to the capacitive pad that triggers the manual refill, and tested it by shorting to GND, and it worked! Now I just need to hook up a microcontroller to simulate that GND trigger, and maybe add a relay or transistor inline with the battery to control the whole thing automatically :-)
@Cyao0The raspberry pi zero destroyer - the icepi zero
I've been hacking away lately, and I'm now proud to show off my newest project - The Icepi Zero!
In case you don't know what an FPGA is, this phrase summarizes it perfectly:
"FPGAs work like this. You don't tell them what to do, you tell them what to BE."
You don't program them, but you rewrite the circuits they contain!
So I've made a PCB that carries an ECP5 FPGA, and has a raspberry pi zero footprint. It also has a few improvements! Notably the 2
USB B ports are replaced with 3 USB C ports, and it has multiple LEDs.
This board can output HDMI, read from a uSD, use a SDRAM and much more. I'm very proud the result of multiple weeks of work!
(All the sources are at github.com/cheyao/icepi-zero under an open source license :D)
Big kudos to #C07F3EA2L8G| for sponsoring this
@RaygenSylvieRupe0we done got the thingamajig thingamajigging. gotta get this fully programmed into ergogen and then finish it up in kicad, but its looking good.
@MinglangDu0i followed highway's macropad tutorial for a bit till I reached the "Routing the PCB" part. most of today was math, but i managed to squeeze this in.
@Zia0Never actually uploaded my OnBoard hacker card jam
@ScooterY0Wired up BL in KiCad for 2.4GHZ for a flight computer in progress!
@arav0I made a PCB for the first time :D I've always wanted to make one before but it's always felt really scary and complicated to me but yesterday I decided to give it a try and do something for solder to learn how to make one and for something I'm hoping to do later this month.
It's a pretty simple circuit that basically lights up an led when you press the button. It doesn't do much but I'm really proud that I was actually able to make something and that it theoretically works.
Need to decide what I'm going to actually make for solder though
@Lukas-U08AT086H8E0Ok so today ive worked way too much on this Mod PCB for the xbox 360 controller that makes it USB-C inspired by this but mine is going to be open source and better but i think i got it! its done! i'm going to buy a few with money from #C07F3EA2L8G|
@Irtaza0After digging through Sprig’s schematics, figuring out the right CircuitPython libraries, and spending countless hours debugging errors in Thonny’s serial shell, I finally got my <https://github.com/Irtaza2009/Hackamon|Hackamon code> (submission to #C0809PN4TPE|
@Blu0Pixeldust PCB in progress! It's my first time working on a project other than Swirl
in a while and is quite exciting! So far a lot of what I have added is very similar to my HackPad and I want to expand my horizons, am planning on adding a temp sensor, and maybe try an oled, light sensor, ultrasonic distance, soil etc as I have never used sensors before and want to see what i can do! Im first going to see if I can figure out the temp sensor though as it is quite confusing
@Lukas-U08AT086H8E0From today on i will be posting more scrapbook posts!
## today:
• Learned how to make really cool art with PCB's its really cool
• Made more of my Badge card fo #C08L288G22Y| yep im already working on it even tough it hasent yet started
if you are curios how to do this cool things on a pcb here is a link
@laith0Think my PCB is getting close to being done !!
@laith0Lazy day + was busy with Eid al fitr, but I did do some tweaks with the PCB. Ran the DRC and i got 0 errors or violations which is neat. Just need to keep tweaking until it makes sense. Also forgot to add a diode for the charging module 😭 😭 😭 have a feeling thats important...
@laith0MOORE editing my PCB! Kinda confused myself with the vias, turns out you dont need them when your PCB is only two copper layers and you got through hole pads. Fun!
@laith0Today I started workin on the PCB of one my projects. Honestly, I'm at least 90% sure I'm doing this wrong, but the fun thing about learning is making dumb mistakes and trying again.
Im pretty new to PCB design, let me know how I did. This is a little nerdy (im super into physics rn) but im pretty close to finishing the design of an Alpha particle spectrometer PCB perhaps to send up in Apex! Currently I need a way to store oscilloscope information I dont know how to get (If i send it up, please let me know if you know how to make this thing store acutal info cuz i have no idea) but right now it should be suitable for home experiments if you have an oscilloscope. Inspired by an old CERN OHL design, it uses a subsequent charge preamplifier and high-pass signal filter (all those resistors and capacitors) to get a good reading of the power spectrum from the photodiode on that signal hole.
@pbhak0day 8 of #C045S4393CY|
polished pcb, made routing cleaner, fixed all drc errors
the PCB is now fully complete!
time to stop procrastinating on the case
Day 11/15 of #C045S4393CY|
• updated my pr!
• started learning in making reversible PCB's while streaming in #C07F3EA2L8G|
@pbhak0day 7 of #C045S4393CY|!
done with pcb routing, will start work on case cad tomorrow!!
this took way too long, if they don't extend deadline i might be cooked
@HridyaAgrawal0Day 9 #C045S4393CY|
got PCB of my hackboard done
And for juice quite a lot of website stuff, but got syncing of most waves survived, gonna add other stats like zombies killed etc. error with updating is a few weird sql row security problems which il fix tmrw
@Rmardia0Day 4 of #C045S4393CY|. Today I worked on the PCB for a personal project of a hexapod. I made it foe cafe, but I will not get the PCB, before Monday, so tomorrow I will work a little bit on a physical prototype.
@Boa_n0day 5 of #C045S4393CY| today I speed ran a hack pad keyboard PCB. created a sprig game and worked on the BOM for my printer.
@Boa_n0Day 4 of #C045S4393CY| I worked on my printer adding a few features. I almost think I finished the printer head. I also worked on adding a pcb for an oled and buttons or smt
@Rmardia0Day 3 of #C045S4393CY|.
Today I "speedran" my hackpad for 5 and a half hours straight. I finished the schematic and the PCB, bur I did not have the courage to run the DRC today, so I will do that tomorrow. (Help, I am so tired)
didnt have time to work on the 3d printer but did a 5 hour cafe speedrun for my keyboard pcb
@pbhak0day 4 of #C045S4393CY|
got some work done on the schematic. fixed some errors in the matrix wiring and assigned footprints for key types.
next on the list is figuring out stabs, then i can get to work on the actual pcb!
@Rmardia0Today I worked a little bit more on the PCB. I got to the batteries, where I am going to use 18650 Li-ion cells, and I will integrate a battery charger into the circuit. I also started with the footprints and only have to do the terminals now. I also worked a little on the theroritical side on how I was going to make it. I realized that I will probably not get the PCB before cafe is over so from tommorw I will also work on a temporary solution for my hexapod.
Day 3/15 of #C045S4393CY|!
this was supposed to be yesterday but scrappy was offline
Just another boring day on working on my Hackboard case! + Rerouted some parts on my PCB
• Put my Pico in a better position but it was a pain in the ass because the new KiCAD updated is so buggy at least for me like it keeps freezing and crashing. And because the project was made in a older version things where not really compatible but i got it done with no DRC errors!
• I made adjustments to the top acrylic part because in the old version the USB-C would not fit.
• Added screw holes to the case.
• Rendered some really awesome pics of my keyboard.
