An illuminated airplane demonstrating the use of 555 and CD4017 chips.
And includes a bah with some extra parts and other goodies!
A good kit, good instructions, theory of operation, and schematic. A great first kit, and fun to have flashing, maybe hang it from something!

A very simple introductory kit, a basic flip flop circuit alternating between a blink and a beep. At US$18 I’m not sure it's worth it.
OK kit. Though, since all it does is beep and blink not something you’d put on your bedside table.

Follow-up to yesterdays demo; Using another power supply I drove the drill press at 12v 3 amps and it did not bog down anymore, and it also did not burn up. Motor case got a tiny bit warm, but no damage.

Good to know you can push this farther!

A mini drill press from Innocraftsman. I wanted to try it, since it can certainly be a little more handy than firing up my big press for small work.
And it works just fine! You’ll see me trying it with wood, plastic, metal, and circuit board material.
No major safety concerns.

An LED Carousel kit from MOVYOOW
A fun and pretty easy kit, though it does have one surface mount chip.

Only real issue is getting the carousel horses all perpendicular, you’d probably want to do a better job than I did.
Good kit,

Mixing Flask Mixer kit from ThreeTom Modular.
A soft clipping 3 input mixer from ThreeTom.
Very easy kit, mostly surface mount pre-installed.

And a good mixer with lots of LED action to brighten your skiff at the club!
Not much more to say, it’s a fine mixer.

Had this spare Jowoom guitar tuner (I switched to the Roadie brand) and figured I'd take it apart.
That's pretty much it. Go see how it works!

An arc lighter. Demonstrates using a big cap, switching transistor, and small transformer to generate a high voltage, low current arc. One that you can actually start a fire with!.
Fun little kit.Needs a 3.7 volt lithium ion battery, which you’ll need to have on hand or buy.

A variable lighted LED touch control Owl.
A fun practice kit. Does have two surface mount parts, the smaller one can be a bit tricky, just take your time. And 60 through-hole LEDs to give you a lot of soldering practice!
Nice kit.

A very instructive kit, showing how red-green-blue LEDs are combined to make many colors. Just like your smartphone or LED tv!
You get to set and blend intensities of the 3 LED colors to get a variety of other colors.
Recommended, a good build and a great concept.

A simple, but useful, kit, two USB powered tiny nightlights.
Surface mount, but about the easiest surface mount you’ll do, so I would recommend this as your first hand SMD kit.

Another fidget spinner with LEDs. This one is a simple switch on/off one, no spin sensitive switches.
Easy assembly, though you really do have to get all the components flat to the board or the case won’t fit together. Would be a great first kit.

An EXCELLENT solder removal tool from Vislone! And US$34! No hand-operated plunger, this has a button actuated solenoid to suck the solder out quick and easy, leaving you ready to do the next one fast, you could desolder a 24 pin socket in less than a minute.
HIGHLY recommended.

4Decay kit from Cubusynth
A Decay ramp generator when triggered, gives you a 5 vdc peak that decays at the rate you set. Could feed a VCA, could modify a filter and so on. At the shortest time can simply be a pulse generator.
VERY simple build, great first kit

Screamer guitar pedal kit from StewMac dot com.
It’s a pretty straightforward build. And gives some nice drive and tone modifications. I’m a keyboard player, not much of a guitarist, don’t expect much shredding in the demo.

Neo Tokyo phaser kit from Djupviks Electronik
A phaser with “overdrive”.
Simple kit, mostly surface mount pre-installed.
Gotta turn feedback way up, but when you do it’s good sounding. Adding CV for input volume spices it up quite nicely Would be a great first kit.

Two kits, one the surface mount, one the through-hole, of a 555 chip oscillator, square wave, adjustable frequency.
Knowing how a 555 chip works to create an accurate waveform is important. .
Would be a fine first SMD or though hole kit!

A Halloween Pumpkin, a little late….
Good kit, probably a 2nd or 3rd because of some tricky soldering, you’ll be soldering on the same side as the components instead of the back side. But not too tough.
And a fun little accessory for your beside table or window in-season!

A battery powered LCD oscilloscope. Not, of course, as full featured as a desktop model, but good for a quick look at signal presence without dragging your big scope out. Or, a good starter scope.
Note: The LCD screen connector is HARD to solder!

Yet another Gikfun clock soldering practice kit.
Lots of LEDs (like 60) to solder on, and you can even see me make a mistake doing so (and see the fix later), and other good things.

Very good practice kit, would be great for a first kit, and a useful thing when you're done.

A clap on/off switch from Whadda.
Straightforward kit, nothing to challenging to assemble. Probably a 2nd or 3rd kit.
It works OK, not great. Takes quite a clap to get it to toggle, and there is a noticeable delay between clapping and the processor noticing it’s a clap.
