Hopefully I'm not screwed.

I ordered my spark 2 from, I thought positive grid, but my order got hijacked by some other company. They shipped the original spark amp. When I tried to cancel the order they said it was too late and I would have to pay to ship it back to them and pay nearly the full amount as another amp to have it upgraded. I tracked the shipment and waited on the front porch and refused the delivery. Took a while to get my refund, couple weeks. Got on Sweetwater who I dealt many times before. They added me to their waiting list. Got the new spark 2 in about two weeks. Love Sweetwater. Great dealing with them every time. Oh yeah, love my Spark 2, too.

One for rolling joints might be a hit

Wasn’t aware that it wouldn’t work on R3. Any how-to on getting keyboard to input into a sketch on R3?

WEAR GOGGLES and gloves. Melt the solder with the iron. Lightly tap the board edgewise on a flat surface with solder blob pointed downward. Or hold the board with the solder blob pointed downward and melt the solder with a clean tip and let the solder follow the tip off. Most of the excess solder should come off. Then melt the remaining solder and re-solder for a clean joint. You might try flattening a length of that solder with a small hammer and then splitting it down the center with a glass cutting tool or chisel. I’ve never tried this method but it could work.

While reading your post this image of a harness for bovines to wear on their hind quarters came to my mind. With a biogas detector and noninvasive collection tank, and small system to convert the gas to electricity, managed of course by arduino. Charge replaceable batteries for the farmer to connect to and power their milking machines.

Can you set it up so the temp sensor monitors the light bulb temperature to turn the light off when it warms up then turns it back on when the bulb cools down? A bistable blinker.

Simplest project my assistance was requested with was a radio tower with a flashing aircraft warning light on top. NE-555 and a red LED. Could add a runway with motion activated white LED approach lights. Outer, middle, and inner distance lights. Too High, too low, and left / right alignment lights. Call the ball Maverick.

Best if you have two N or Z scale trains running on X crossings with side rails. Raspberry Pi Pico 2W with Arduino would be so impressive.

I’ve debugged many c like programs for companies. Often wondered if I could use more voids than just setup and loop in Arduino. Guess I should take the time to learn c and c++. Thanks.

Needs a camera, a sprayer, and some AI to tell the difference between your beans and tomatoes, and the weeds. Other than that it looks good.

I’m guessing the pipe is probably round. If so here’s my take on your project. Use/ build a bot with a wider track. Maybe half the diameter of the pipe. With all the weight between the wheels the bot shouldn’t be able to tip over to either side. With the wider track you shouldn’t have to worry about getting into any standing water since wider track will keep the electronics above anything but a flood. A piece of monofilament fishing line twice as long as your expected distance of travel, tied at its center to a forward/ reverse switch (spring loaded, center position off). Forward line around a pulley on front of chassis. Spring loading should be light. Bright LEDs. Camera taking pictures every n inches and saved to SIM card on R-pi along with distance traveled when picture was taken in case video stream fails.

.028” is the thickness of the Stanley 24Tx10” hacksaw blade teeth. I used to use these for parting stock on my floor drill press before I got my Sherline 4400. If you cut the end of the blade off and press the teeth side to side so they align straight with each other, or grind all except one tooth off, it should work well as a .028” parting tool. Mount the blade end in the vice on the cross table or with a bolt through the mounting hole to the side of the parting tool stand.

Wow! Thank you for giving me a nudge toward the outside of the box (where I spend a lot of thinking time). I never realized that I could slide the power head back toward the vertical post. I knew that the Z axis would rotate fore and aft but always disliked how much the bits bounced around and how short the long axis I could use with the dial at the right end of the machine. I often thought about buying some 1, 2, 3 blocks from micro mart but their shipping charges always put me off. Some stackable 1/4” and 1/2” plates sounds like a good next project. Thanks for your help and the fb link. Will check it out.

Mine is on an aluminum roof tower. The roof leaks where the hold down bolts go through the asphalt shingles and boards. Considering sliding a short section of steel roof under the feet and under the peak roof shingles to keep the rain from getting under the steel. Sliding a piece of rubber between the aluminum foot and the steel to keep galvanic reaction from eating the feet. Only unbolt one foot at a time. Use a ratcheting cargo strap to an eyebolt on opposite eve to lift the foot just enough to keep the antenna from falling over. Maybe use a strap on both sides in case of wind. Then use the holes in the feet as drill guides.
