Hi Frank. Well, I maybe *could*, but the first beer I'm aiming for is Urquell (which being a pilsner (THE Pilsner) will use my conscripted old fridge kegerator cum lagerator, making it a double Teensy-beer). Depending where you are, Pilsen is a lot closer to you and if you were me you'd be...

Well, I have no idea what i did except do something that 1) Made the board not work no more; and 2) Made me want to not think about it a whole lot (which further complicates giving any useful information). I was kind of hoping there was a standard, "Oh yeah that happens all the time here's a...

3.2. I have an SD/Wiz820 soldered on top of it. 5V supply. I *think* I've shorted my 3.3 V regulator (LP 38691 I guess. Datasheet says "Thermal overload protection". Not sure that translates to "short-circuit protected".) Too dissappointing to poke at it thoughtfully, I'd rather whine on...

I tend to vacillate between over Maximizing and the unspoken, "ANYthing,PLEASE, just GET ME PAST THIS DECISION!" approaches. Here, I'm pretty comfortable taking a mostly Satisfying way. I'm better armed to face the next library choice situation, tho and for that I really thank you guys...

Like the day after, with a hangover, I reread my post... I don't know what I was thinking, "What's the easiest secret to success in the stock market?". Aye caramba! But tho I should have expected no easy answer, it was a good question--Without familiarity how this arduino coding universe works...

We are (sadly, I'm the arduino 'expert' for our STEM group) about to play with the nRF24L01+ for a timing gate project where start and finish lines are 301 m apart (Soap Box Derby). Looking at various simple examples. Looking also at all the various libraries available. Wondering about...

Advice, please, general and specific. I want to use a tap (cold) water source and a siphon from a boiling stock pot to a mixing valve to source me up to 8 gallons of water at an exact (like, +/-2 F) desired temperature (from ~150F to ~180F). Point Of Use (POU) hot water heaters abound but not...

Right forum? Apologies, if not. I'm going to try this. We've got fleas. TheWWWisdom out there* is that fleas respond to light, to vibration, and some other things. Specifically not just light but modulating or intermittent light, as if someone tasty was walking by. I've got the gel cell...

It's an honor and a real pleasure playing with you guys! Jonr, SkiMask, re your similar ideas (Torque Indicator) if I had or could contrive a shaft that'd twist a reasonable amount*, two bike computer-like sensors, or two light interrupters**, one on each end (well, spaced as far apart along...

Thank you, SkiMask. Some more detail: We're only using the gearboxes from the grinders. The power source is a hand drill which has a more reasonable speed, 0-10 turns per second vs ~200 for an RAgrinder. I'm not sure but I'll bet that the low speed torque is much better with a drill than the...

So the human powered submarine project is in its early stages, we have almost a year to play. Right now we're setting up to play with propeller designs. Available power is about 1/2 horsepower (max, in their dreams). Shaft speed tbd. We're trying to build a test cell to test various...

Morgan and WHguy, hi and thanks. There was a better sensor (MS5803 sounds right) but at the time I selected and bought, there weren't any I could actually locate. I'm moderately locked in now, and as long as I can make it work it's ok. Plan is to try HWguy's SPI.sets; as long as I can SPI.set...

Hello my invisible friends, I'm pursuing this project again after some quiescent time. A question, in a moment but a note on coping with water(proofing). Instead of conformal coating or a pressure vessel, it occurred to me that if a board were enclosed in, say, nitrile glove with the wires...

Thanks, excellent point about the expansion issue. That's especially scary to contemplate as it's one of those failure modes where I'd just be left wondering what happened and probably have no recourse but to ignorantly blame something and try it again, blindly. Repeat. <shudder> I'm...

You guys are great! I was beginning to feel unrequited; I see that it's only been ~24 hours tho so I think I'm impatient. It's as if y'all have real lives to attend to in addition to tending this group! :- ) WMXZ--No, I hadn't seen this. I promise I'll do a good job of absorbing it...

Hi all, my first post. I'm trying to make a 0 - 30 PSI (, ~2 ATM, ~30' H2O) depth and pitch controller (see ISRsubRace.org for why). (Later, more on the rest of the system if people are interested.) So I'd like to integrate an InterSema MS5541C to a Teensy 3.1. Digikey 223-1099-1-ND, btw...
