BM1AT Redesign

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

#1 BM1 - AT by A.Owli
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.

As indicated, I prefer Kicad V3 or V4.
Thank you all for your interest.

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.

Do you have any schematics?

Handle / Grip design with gear & Latch
The design needed is for a handle / grip that when squeezed, it will make a 3/8" square bar, which is in a 1 1/2" high extruded piece, travel aprox 2 1/2" towards the grip. See short video. This also needs to be able to lock into multiple positions when squeezed and also have an easy release so that when released it springs back into its original open position. This will be attached to the end of the 1 1/2" high extrusion. There are 2 openings in this extrusion. One along the top will be a square opening in which the 3/8" square bar will be encased and the other one will be a round hole which will encase a 3/8" round tube in which water will travel through. This round tube will need to extend out the back of the extrusion and through the handle and attach to a water hose. The handle / grip needs to extend up above the extrusion a minimal amount. The attached picture of my prototype extends way too high above the extrusion. One thought is to incorporate a rack and pinion type gear to achieve this. Any type of gear or mechanism will need to be enclosed in the handle.
Biological Cell Cluster
I am looking to obtain a 3D CAD model of a biological cell cluster in order to transfer it to a multiphysics simulation software (COMSOL). The cluster will consist of 120 'cells' in the shape of a hyper-dodecahedron (https://theory.org/geotopo/120-cell/ ). Each side of each dodecahedron must measure ~5um.
Bottle Design
My company as of now will sell stainless steel water bottles. The bottle will be designed to keep beverages cold for 24 hours and hot for 12 hours. The purpose of the design will be for me to send it to a company that will mass manufacture the bottle. The heart portion needs to appear more as if it is coming from the inside out vs it being screwed or glued on to the outside of the bottle as it is pictured. It would also only read 'Jorvine'.
Quick/Easy 3D Rendering / Photoshop project for high-end home audio company's new product!
I would like to work with someone who can take my product images (high resolution JPEG images) and add/modify them to reflect a new version of our product. The deliverables will be high resolution JPEGs (modified versions of the ones that I submit for this project). Our product, "LIO," is a home audio product (see: www.vinnierossi.com). Currently, the aluminum top panel (top cover) is has no holes. We are developing a new vacuum tube preamplifer stage in LIO and there will be two vacuum tubes that plug into two sockets directly below the two holes added on the top panel. I need new renderings that show these tubes: - Front views - Angled views The vacuum tubes need to be show in correct proportion and must look as realistic as possible, even glowing (so it looks like this is still a product photo). The ideal candidate for this product will be well versed in: - Photoshop - Solidworks - AutoCAD - Any other software that can get the job done. I will supply the product photos and examples of what the vacuum tubes look like, and where they are to be located on the top panel. Once the rendering is completed for the front and angle view, then they can be used for all the different variations of the same product (with different front/side panel, top panel, and knob color). Thank you, Vinnie
Cartoon Animals 2D to 3D Conversion in 3DS Max
Create our 2D animals in to 3D cad and make them totally ready for key frame animation. The animals need to be in the same style as the cartoon landscape seen attached files. As you can see the animals are the same in basics so small changes need to be done to create the second animal.
