KiCad problems on windows 8

Hi

Don't know if this is the best place to ask about this sort of stuff, but here it is:

San Francisco Circuits - Custom PCB Manufacturing & Assembly

Hello Robot-Humans,

It's a pleasure to have joined your very fun community.

I hope we can help with some of you that may have needs for custom circuit boards, either for your personal or professional needs.

We're located in San Mateo, California and have been providing PCB manufacturing and PCB assembly services to our customers since 2005.

  About a year ago my brother and I engaged on a quixotic project to build from scratch a low-cost PCB printer for photoresist.  Read more

Droid Planning

Firstly Thanks to Oddbot, Pome & the Dagu team for this amazing Robot.

Assembly time was about 16 hours, that included rebuilding the right wrist to get the servo in a position to be able to pour a liquid ;-)

Life with Little Free time!

Right... It has been Way to long since I have had enough time to jump back into this amazing community so this is a quick Catch up on what has happened and what I've learnt in the last 9 months! (Why-Lumi once said if it's not on LMR it hasn't actually happened! & Some Pretty AWESOME Stuff has happened!)

My PCB's Are Here!!!

Hello everyone my PCB's are here, they were actually meant to make my robot more tidy as shown here (turn off the sound)

Maxhirez' PICAXE board



A week or so ago Max was trying to find a layout for a PICAXE 18 or 20 board with an L293/754410 motor driver. He was hoping for something similar to what sanc04 assembled.

Now all I need is a $3k laser cutter.

Edit:

I take it back, it's only 3k if you opt for the delux package :)

I decided to try making an Arduino Pro Mini at home.  Being done, it's not worth it.  You can buy one for a dollar more than you can make them, and it took awhile … Read more

Small Form Atmega Fuse Doctor

I'm working on trying to make a SMD Fuse Doctor I can send to OSHPark.  I don't suppose someone with a good eye could double check my schematic, and if you are a grand soul, my PCB layout too?

PCB help (Eagle)

Hi all!

I have made a board for the pic16f690 with some servo connections and some other connections. I think the file is kind of self explanatory. I'm basically just wondering if any of you used to doing PCB's or working in Eagle have any warnings or advice on this board. i am trying to get a clean board and also trying to make it onesided. So all tips appreciated.

Thanks in advance

PCB CNC Drill

So this is the basic idea, more so I don't forget but any input/comments always welcome.

Create a mini CNC for drilling PCB's, it would require...

Building an X/Y Table similar to Geir's (sorry can't link, using a Tab). Instead of a pump hook up a 12v motor with a drill bit adapter

Mount the motor so it can move on the Z axis, either on a spring with a servo to push it down, or threaded rod like normal CNC mechanics. Use the handy TIP120 for switching on/off. (2.2K resistor, Diode)

Pcb help

HI,just made my first arduino pcb's.They turned out quite well except um, after 7-10 days now the whole copper side has started going black. (1)Is there a way to prevent it.I hv seen green coating on professional ones.Is there a cheap alternative to elongate their life? (2)Also drilling turned out be a hell of an affair.I dont wanna buy a drill press and working with my hand drill to drill them was a nightmare.Any solutions? Thanks!

My PCB Adventures...

Inspired by Birdmun's adventures in PCB's I decided to try my hand at it. I'm no guru, in fact I'm pretty noobish to this whole thing but I thought I'd share some of the things I've worked out with the help of friendly LMR'ers.

All the equipment I'm using is standard stuff that some folks may already have around:

1. Laser Printer. I had an inkjet which will work using a different method that employs special boards made for UV etching but I             picked up a Brother HL-2240 for $60. It was the cheapest no-frills LP I could find.

Free PCBs looking for a good home

I accidently sent the wrong Gerber files when I ordered some PCBs from http://iteadstudio.com/ so now I’m stuck with 14 boards that I don’t need.
Lesson to be learned : Don’t order PCBs late at night after a 6-pack of beer…

This was my first DipTrace project and I do believe they work. I have not tested the board in detail as I had started another project when they arrived. These are the same boards that I mentioned here

First foray into homemade PCBs

**Update at the bottom.

  Alright guys/gals, it has been a coons age since I posted anything even remotely useful of my own. I have managed to break that trend with this 'bitty blog, somewhat. I say somewhat, because, everyone and their brother has posted a how to about DIY PCBs. I will attempt to offer some bit of information that others have not, doubtful. :)

Project Phoenix (ALAN's new look)

hello everybody! it's been a long time since i have updated ALAN, i've been busy for some events, and still am, but i have manage to fix some bugs.

i still haven't added his arms yet, and the battery died (must be a short, RIP), but i will buy a new one when i have time (and money).

so here are the updates:

CAUTION: what you are about to see can and will make you sick, i warned you about it, so prepair a bucket and a mop!
