I have used the ANALOG DISCOVERY (Ver1) for some time as my bench scope, have been very happy with it. We have used it for a portion of our Circuits Analysis class at the college level with good results. With a reasonable laptop, a small box of parts, an ARDUINO, and some jumper wires a nice portable laboratory is easy to carry around for education, hacking, or just amusement. More versatile than my Fluke Scopeometer, my NI PCMCIA scope and DMM, and many more functions.

The need for protective equipment is well worth paying attention to. I also suggest use in a WELL ventilated area, protect the surface you are working on if indoors. Wear only clothes you do not mind having permanent stains on. Ferric Chloride and Cupric Chloride are both corrosive chemicals treat them with the utmost respect and dispose the used chemistry in a proper manner. Having used both in modestly high volumes and seen the damage they did to commercial grade circuit board processing equipment, I suggest you think safe and work safe.
News - T³: Laminating Circuits
about 5 months ago
Please keep in mind that it is now possible to get some reasonably good flat conductors, I even have a nice flat USB cable. When I need to laminate way too thick objects my laminator has a nice reverse switch so that I can bond part of the sheet and back it out, then bond another edge, etc…. for some objects I force air into the packet to act as a pillow, for others I use a small vacuum pump to remove the air to make it more conformant. I also have an attachment for my soldering iron that has a flat disc at the end (10mm) that allows for spot lamination.

Could someone verify the DC and AC current ranges, the above is not quite the same as the USER MANUAL, thank you

Someone asked when is the last time a soldering iron spit in my face, well that would be YESTERDAY shortly after posting my comment. Soldering a 12 AWG wire into a terminal and boiling flux bubble shot out some little particles of hot solder. And as to the comment about safety glasses in Europe, having spent some time in Germany and Hungary teaching and repairing equipment, there is most assuredly a REQUIREMENT for safety glasses AND positive ventilation of the fumes, AND a requirement to deal with the dross and other ruminant’s of the soldering process. When we teach students here at our college, safety glasses are mandatory for almost every activity, including powering up uncovered circuit boards, its no fun pulling chunks of blow up capacitors out of one’s face. Accidents happen, its far easier to work safely than to recover from an accident AND fill out all the resulting paperwork especially in the workplace (can you spell OSHA?)
Seriously, staged or not, soldering iron in hand ONLY after safety glasses over eyes. And in my labs no hand or wrist jewelry allowed! It is ALWAYS important when educating to set the correct example, ALWAYS.

One addition that might be considered is an ESD protection mat-wrist strap kit. Always good to protect integrated circuits from nasty little zaps. I like my 3M mat, a bit pricey but it does the job well
