I came across these two products and wanted to share.

For less money, you can get just the pcb and build with a few dollars in parts from Tanner’s

I have just received the two pcb’s from EMSL and they are very high quality boards about 0.100" thick.
The beauty of these two kits is that you can build just about any circuit for a LM555 timer IC or an LM741 Op Amp and replace the IC in the circuit with these board by just wiring them in as if they were the IC. This will then allow you to use our oscilliscopes, signal generators, and power supplies, to actually trace out the signals that are normally hidden within the tiny black box that is an IC. You can really learn how these devices work. The operational amplifier (LM741) is the most basic analog chip around and understanding it is vital to understanding analog electronics. Even before these chips (or even solid state devices) existed vacuum tubes were being used to build up operational amplifiers in much the same way this board uses 3904 and 3906 transistors to build up a working clone of the LM741 op amp.
Before the days of a $0.5 microcontroller, the LM555 timer was the most popular chip for DIY experimenters. It is truly amazing what you can create with just this chip, and a few capacitors and resisters.
@artg_dms I think these kits make great learning tools for you to teach a few classes at DMS!
