I soldered on the toothless alligator clips today (what gems! ) and drew up an aquatic sketch to have some examples to show folks for the workshop I’ll be doing. It works the first, because the bootloader itself holds the chip in reset (thanks, Dave). After puzzling for a minute why the FTDI programming only worked the first time after burning the Arduino bootloader, I realized that I hadn’t put in the auto-reset capacitor between the DTS pin of and the RST line.
I had to catch a flight out to LA-though it was delayed 2 hours-but I managed to throw together a board to bring with, so I could do some work on the plane (of course, I ended up not doing any).
And Brian was telling me that some special-purpose boards can have the passive elements like those baked right into the various layers. What’s all the more astonishing, is that there is yet a smaller size, 0402, which is about the size of a grain of sand. I used a bunch of 0603 resistors to provide the loads on the capacitive pads (those rectangles along the top). I’m mostly proud for remembering not to pour a groundplane, as it makes it a pain to solder. I know that APC Circuits has really quick turn-around for boards with solder mask and such, but I didn’t need it. These cost $8.90 apiece, which is pretty reasonable. The “barebones” option from Advanced Circuits is a pretty good deal too. Length: 7.09 inch, just clips size: 1.18 inch -Clip diameter: 2mm ◉ 1 x Reusable transparent plastic box -Size: 7.87 x 4.72 x 0.71 inch -Package Total Weight: 10.My circuit board order came in - it’s always astonishing how tiny the things are, these boards are about the size of two postage stamps, side-by-side. Length: 7.28 inch, just clips size: 1.22 inch -Clip diameter: 2mm ◉ 20 x Toothless Alligator Clips. Package Include ◉ 20 x Alligator Clips (with 40 rubber covers). Warm Tips Please keep the metal wires alligator clip out of reach of children and pets. ◉ The diameter of alligator clips is 2mm, fit for most painting stand base for airbrush hobby modeling, please take care if standing base hole diameter less than 2mm Cautions ◉ Micro steel toothless alligator clip sticks are professional for miniatures/tiny crafts/mini model parts, can not use in big model parts spraying ◉ Please do not use these alligator clips if your model painting stand base hole diameter less than 2mm ◉ Please keep alligator clamps distance to avoid clips wobble if the Model standing base diameter more than 2.5mm, then the painted oil will mix together from different model crafts. ◉ We use sturdy material and strong bite design, the rubber cover is hard to fall out from crocodile cover, you can install it back conveniently even if falling out. Easy Usage ◉ Please use the alligator clamp directly, without assembling the rubber head Model alligator clamps could keep your hands free and clean while airbrushing or hand painting your model projects. We have focused on model/painting/gundam/DIY instruments and related accessories research/design/production since 2015, so as to provide convenient use with high efficient after combining the technique and artistic inspiration, also innovation is our eternally target.
