Chris Gammell Build Log


#1

Hello world!

My name is Chris and I’ve been working on electronics for 10+ years. I’m hoping to learn more about embedded and do a bunch of fun electronics projects while on CE.


#2

I’m creating this post as a template for others getting started on the forum. The first thing new members should be doing is posting to the build log as a placeholder and introduction.


#3

Excellent, I’ve been doing software for 20+ years and learning electronics, I’ve done some embedded software development and would love to help out where I can.


#4

This weekend I’ll be building up the “Shine On You Crazy KiCad” boards (videos here: Early look for forum members). I just got all the parts in today:

I also will be building up my Whizoo reflow oven and posting more videos here!


#5

Still need to build up the Shine On boards, which shouldn’t take too long. The RPi programming will likely take me much longer.

I also decided to take on a project with RS485 transceivers. I’ve been meaning to do this for a while and decided i needed to stretch my layout muscles (without filming it). Will update as it gets built:

Repo if you want to follow along:


#6

Too lazy to make a 3D model for the connectors, but here’s the view in 3D


#7

Just got two of these beauts in the mail, time to start playing around. Maybe another CE header breakout?


#8

Update: the blink has blonked!


#9

Just realized my notifications were all messed up on the site, so I haven’t been subscribed to certain topics. If you w ere waiting for a response from me, I’m sorry about that! Also, if you call out my username with an @ symbol, (ie @ChrisGammell) it will ping me even faster.


#10

Achievement unlocked! :slight_smile:


#11

Built up a new RS485 board for the CE header. Not actually planning on making this first rev into a course, just wanted to build some electronics for myself. Excited to test it out, hoping the CE header continues to be a good fit for future projects!

Of note for future boards…need to add some kind of “legs” to the edge of the board if I’m going to have a significant overhang like this, it doesn’t balance under its own weight.


#12

Nice, I’d be interested to try RS485. I’ve not used it before.

Also, I noticed your Isopropyl alcohol in the background. Do you use that to clean flux?


#13

Yep, I do. But this is particularly weak isopropyl (72%) so it’s not that great.


#14

Should be able to get at least 91%+ up to 99% at any local drugstore, if I was closer I’d pick some up for you.


#15

Yeah, think I got this with my grocery delivery, need to stop by the drug store next time.


#16

What is the best way to apply to the board?

I’ve heard toothbrush. Thus far I’ve used eye glasses wipes but they don’t work very good. I ordered these from Amazon yesterday so look forward to trying them out:


#17

I’ve seen many examples on YouTube using KimWipes with a brush. I picked some up a few weeks ago, they seem to work as advertised.


#18

Hi Chris can you send me your email, I wish to refer an advertiser to you.


#19

Hey @ChrisGammell, I’m excited to see how these Beaglephone-Pocket boards turn out. Are these going through the Whizoo reflow oven?

Got my PCBs back, look decent. Parts come in today. pic.twitter.com/dPxFdWleJg

Actually planning to take those to the reflow oven at mHub, think it’s a Manncorp
