DIY PCB Etching: Collecting Chlorine Gas (Read: DON’T)

tl;dr: There are much more efficient ways in which to produce chlorine gas than by electrolysis, so stop hoping and go buy some hydrochloric acid. I ultimately did not achieve anything practical by producing the gas. This post is only a log. Accidentally oxidizing my cuprous chloride solution Technically, it’s possible to turn a cuprous […]

DIY PCB Etching: Colors of Compounds and Helpful Links

UPDATE 11/10/11: Although most of these colors are accurate when dealing with concentrated solutions of salt, some are not (e.g., descriptions of copper (I) and (II) chlorides are mixed up). Take it with a pinch of… salt. Yellow? Copper hydroxide is supposed to be green! If you have already been at this for hours and […]

DIY PCB Etching: Electrolyzing Salt to Produce Cuprous Chloride

tl;dr: You cannot produce an effective cupric chloride etchant using only salt, copper, and electricity. Yet I spent a week trying to do just that. Essentially, I wanted an effective etchant-producing method that didn’t require buying anything out of the ordinary. I mean, all the right elements were there (i.e., chlorine and copper). Unfortunately, other […]

DIY PCB Etching: Overview and Production of Ferric Chloride

I liked the look of the LED-outlined propeller, so I decided I would etch my own PCBs to make it easier to light up all three propellers. I’ve spent the last week researching DIY PCB etching methods and doing some unsafe home electrochemistry that has left me with minor chemical burns in various spots all […]

My first robot!

My first electronics project, for that matter. I am currently taking an electronics class at my high school, and as part of the course, we are required to order and build an electronics kit. Since the kits provided were, in my opinion, too easy for me, I decided to order my own parts and build […]
