Electrochemical engraving seems to be pretty easy: you order micro-screen masks from tustech [tus] and they appear remarkably quickly. I sent them a large PDF of the badger logo Ieva did for me and they had the masks in my mailbox 5 days later.
The chemistry is easy (I have plenty of ferric chloride) and I know that an engraving machine is really just a battery charger. But I was searching around for “electro engraving” on ebay, trying to see if anyone offers pre-mixed nickel plating chemicals, and stumbled across a Chinese-made engraving machine that was so cool-looking that I had to have it. I am a sucker for VU meters and switches and stuff like that.
I was sitting there thinking “I wish the label on the TIAMEADJ went to 11, so it was more powerful,” when I noticed the brand. I swear I only noticed it after I had been playing with it for a bit.
Presumably, “STING TL” and “HAND CO” are the wossname, and the red button looks like a reset.
You cannot beat that.
Cross-cultural technology challenges are interesting and fun. I know a guy in the 90s who went to Akihabara in Tokyo and bought what he thought was a really cool mini-laptop. It turned out to be a phone, that depended on docomo’s data service; i.e.: it was unusable in the US with its primitive cell networks. I’m sure there are US-made appliances that are just as mysterious – the difference is that most of the rest of the world is, at a minimum, bilingual. We Americans seem to feel that you should understand us, if we just shout louder at you.
