BM1AT Redesign

in 3D Modeling Design held by MUZA
Contest Closed
Description:
We have a board designed in Kicad with through-hole components and want to replace most of them with SMD counterparts. Board dimensions, terminal blocks and a few more components located around the board's edges cannot be modified.
Specifications:
Board dimensions: 8.200 x 3.420 inch
PCB: 2 layer FR4 1.6mm green
Integrated circuits: ATmega1284P-PU (x1), ULN2803 (x2), 74HC595 (x3), CD4021 (x3), DS1307 (x1) and PB82B715P (x1). There is also a piggyback step down buck converter that may be integrated in the main board but this is not important now.
Passive components: 66 1/4W resistors, 28 ceramic capacitors, 31 diodes, several plug in terminal blocks and more.
Wants:
We need the Gerber files for manufacturing and the BOM of the new SMD components used.
Software:
  1. KiCad (4)
  2. EAGLE

Hi
As you can see I did the job as you desired it by replacing THD devices with SMDs with defined specificities. As the density of devices on the board and the traces’ traffic on each layer are high, I tried to fix this problem in 6 layer PCB as you wished and it took a lot of time from me and it is prepared now but I recommend to use 8 layers PCB to avoid manufacturing errors. I am ready to do this for you if you want it. I’m looking forward to hearing from you.

Hi A.Owly
Thank you for your interest in my project.
The original board is built in two layers. If the conversion to SMD requires more than two layers, least 6 or 8, then the production costs will skyrocket making the project unnaffordable.
I other designers come with similar solutions then I will abandon the project.
Regards
J.M.

Hello Mart
Thank you for your interest in my project to redesign the PCB of BM1AT board.
I've just attached the electrical schematic for the board.

Mosquito Trap Redesign
We want to redesign our UV LED mosquito trap, an outdoor product to be placed in tent, outdoor café, farms to reduce the damage by mosquito. It should be simple, solid, low priced, slim, good quality and fashionable- a mid-way between high-tech and disposable traps. We would like its housing to be partially transparent for the visibility of LED light. Also, we prefer the entry point for mosquito to be a maze design. Type: Mosquito trap Target Audience: All age groups Competitors: enclosed in attachments Design: Maze entry point, partially transparent body, UV LED light, PCB board, cotton stand to put cotton soaked in mosquito attractant liquid, 2AAA battery case Material: Plastic Any software is acceptable if STL format file can be provided Any further questions, please feel free to comment.
Leaf Dental Care
My company is "Leaf Dental Care", and our mantra is "Eco-friendly Wellness". We will operate an eco-conscious dental clinic that treats our patient with a holistic approach. The project is to create a visual diagram of what the Reception Area and Operatory Room will look like. The Reception Area will be ~400sq ft, and have a store front with floor to ceiling windows. Theme: yoga studio, spa, Zen garden Color Scheme: White, earth tones, wood, stone. The waiting area will consist of a "retail portion", and a "reception portion" Retail Portion: There should be store front display for retail items such as organic health and beauty products. Like an "organic" Sephora. Our neighbors will be high-end retail stores, and we should blend in. Reception Portion: My logo should be displayed behind the receptionist desk. There will be organic cotton fabric couches for people to sit and wait. The kids play area will consist of wooden block toys by Melissa and Doug. LED television will be playing health educational videos. Patients can fill out medical information on tablets. Lighting will be indirect LED lighting. Ambient music will be tranquility music. All medical professionals are wearing yoga clothes instead of scrubs and lab-coats. Operatory Room Diagram: The theme is carried over to the operatory rooms.

I want cool, interesting designs of a holder for baby wipes. Moms hold wet wipes in holders because it's easier to handle & pull wipes from. It will be easiest to simply look at the photos. But, this is a container for people to put wet wipes in for their baby. I attached photos of competitors. This is just for reference, there is no need to copy them. This is JUST of competitors.
