Surely there's an app...? (Software recommendations, please)

So, I have this new HP Sprout that I totally wasn't expecting. It's got a large touchscreen and this cool projector-scanner-touchmat combo that should be really useful for... something. The first thing I actively want is to be able to create files for my laser cutter (running Lasercut5.3), just by drawing with fingertips or stylus.  In my head, I see a version of Inkscape that works on the touchmat, but only responds to the stylus (to save weird lines from knuckles, elbows...).  I have Inkscape downloaded, but it won't work with the touchmat. Second, it would be nice to start learning how to create are actually 3d already, that could then become lasercut-able or 3d printable. Again, it would be nice to use the full potential of the machine, so what software would you recommend? Third... what?  have you got any cool ideas? On top of all this is the consideration of cost.  Free would be nice - if you are a software developer, I don't mind having a go with Beta products (I'm known for breaking code, so if it can survive me...).

Fluorescent Plants

Recently I presented a science teacher in my school, Mr. Zhang with the idea of growing plants with tonic water which contains quinine to see if they would glow under a black light. Today we saw that these bean sprouts had defused and taken in the tonic water, as a result the bean sprouts were fluorescent under the black light. I first chose the mung bean / bean sprout because I know that bean sprouts are translucent and it would be easier to see the glow, but now I want to find out if the seed will take in the quinine, and if so would the quinine be in the flesh of the plant at all. Another test that Mr. Zhang and I were considering was to use a tonic water in a hydroponic system to see if the plants utilize the quinine. Dr. Paul Williams suggested that I grow fastplants in the dark, because their stem is translucent is grown in the dark. (Mr. Zhang knew him from a workshop he did involving fastplants) I'll be updating this as I continue the study, I'll start growing very soon, as soon as I order the supplies that are necessary. The picture below, is of two mung beans, the one on the left took in the quinine, and the one of the right is normal.

Kombucha or sprout heater from a potpourri pot or other appliance?

I need something to heat a bucket of kombucha tea to 70 degrees Fahrenheit when the heat is off in the kitchen where I will be keeping it. The temperature dips below 50 degrees Fahrenheit in there. I also need something to warm sprouting jars, which I'll be keeping on a shelf that I plan to enclose with a window blind or something else to keep the heat in, but allow ventilation. I don't think I need a thermostat for either of these. The temperature doesn't have to be exact. For the kombucha, I could buy a heating pad for $60 or a heat belt for $20 and pay to have them shipped or I could go to the local aquarium store and buy some fish tank heaters, but I'd prefer to spend less, make something myself out of something old and not support an aquarium store. I'm not a big fan of fish prisons. The thrift stores around here have lots of old appliances for $2-$5 each. I thought I could make heaters using the heating element of one of the small potpourri pots I've seen at Goodwill. I saw online that these pots are heated with a wire wrapped around the (irremovable) pot. Any thoughts on how I could make heaters with this heating element that are safe and not too hot? Any ideas using other appliances? Another option would be to find a cheap heating pad (for heating people) without auto shutoff and use that on the Kombucha at least. I'm not sure that that would be warm enough though, but maybe it's a more worthwhile option that trying to make a heater. What do you think? Should I forget making something for the Kombucha and look for a heating pad instead? Thanks for your help.

Seeds

Hey guys, finally a different question today. I'm trying to get some seeds sprouting and I put them in paper towel (wet of course) and they've been in there for a few days and still nothing. Are they duds? Sorry for the confusion everyone, I'm not growing weed (right now), these are seeds from a really hot pepper that my cousine grows in his garden down in the states.

Biology question?

My neighbour cut down a tree last year, down to the ground. This year it sprouted shoots again from the cut edge. My question is by what mechanism did the remains of the tree "know" 1. It had been cut off and should produce new shoots if it wanted to survive, 2. When to start producing these shoots. i realise it is triggered by day length and temperature rising BUT how does the tree measure these things?

How do I replant tomatoes without killing them? Answered

The instructions that came with the tomato kit said to plant *all* of the seeds, so I did.  I didn't expect all of them to grow.  So now I have a basket that's now overflowing with cherry tomato sprouts, and I'm worried they're too crammed in there. I'm also worried that if I try to transplant them to another container, they'll die! What do I do?

How might I thresh barley to make beer??

GMO sun flower seeds, how can I tell? Answered

Build a warming/cooling box for maintaining temperature range year-round

Hi all, I need to build a box about 75cm wide, 50cm tall, 50 cm deep, that will maintain a temperature range of 20-30 degrees C (about 68-86 F) in ambient temperatures of 0-35 C (32-95 F).  What are my best options for heating and cooling? For temperature regulation I imagine I'll be using an aquarium thermostat for the heating end of things.  What would be best for cooling? I am imagining a plywood frame with a plastic tray insert, covered with styrofoam sheets. Pretty simple stuff. It will probably hinge open on the front face.  I'll be keeping fermenting and sprouting foods in it. thanks for any help and ideas! -bs

Need some answers on oranges... Answered

This summer (I think, I really cannot remember) I set up a propagator to grow some bamboo seeds I bought off eBay- Instructable coming soon on this topic- and then off the success of my bamboo seeds, I stuck a few orange seeds in as well. They grew alright, they're pretty huge now and I just re-potted them today into new, higher quality soil etc. Whilst doing this I discovered that each seed (I only had to successfully grown seeds) had spouted two saplings. So when re-potting I found out I didn't actual have 2 strange orange saplings but 4 of them with totally independent root systems. Albeit Two out of the four had not been receiving as much light as the others so there are two huge dominant saplings and the two smaller ones that grew in their shadow.  Is it normal for orange trees to grow two sprouts from one seed? I haven't tried growing them before so I don't know. Or have I got magical seeds, or a divine calling to grow plants? ;) Any help would be great,   Tom

how much potassium nitrate should i use to speed growth of watermelon seedlings?

Hi, I have several KG's of potassium nitrate, and am currectly growing watermelons, among other plants, however my concern is mostly with the watermelons. I live in mackay, tropical queensland, the sun here is very harsh, and when the wind blows, well, its pretty hard. i have only a limited amount of time before these seedlings use up all the nutrients in their dirt, (they are currently in an egg carton filled with dirt), and each their maximum size before they start to starve. I want to know, how much potassium nitrate i can use to boost their growth to get them as big as possible for when they go outside. Where i live, the house is pretty aerodynamic, you exprenice windyness from all four sides, so i need them as strong as possible for that time that i plant them outside, in large individual pots, until theyve grown enough to be planted around my spoon drain. Anyway, i need to get them to grow ALLOT, and i have the potassium nitrate, however, nitrate is toxic to plants, so i need to know what a safe quantity might be. im not asking for the exact best value, but just anything that will aid in boosting growth before they get repotted would be great. thanks. also, my tomatos, black russian and some random huge tomato, is growing very slowly, would nitrate help them also? and pumpkin, when the seed sprouted, part of the seed was dead, and so two starter leaves were bound together, and died, leaving it leafless. new leaves are starting to appear, but not fast enough as its turning yellow, again, would nitrate help?

Hey, let's invent this immediately!!!

OK folks, how hard can this possibly be?Yeah, yeah, I know. Probably REALLY hard. But if we all team up and combine our gray matter, can't we overcome any technological obstacle with our collective geekiness?I want to see an affordable, open-source doodad that can turn an LCD from a dead laptop into a working external flatscreen monitor. It should accept digital & analog signals and allow us all to hack up beautiful screens ready to embed in our brilliant projects, while keeping LCD's out of the landfill.punish3r valiantly went down this road: https://www.instructables.com/id/Laptop-Converted-to-2nd-Monitor/but then ended up "cheating" (his words, not mine) by using software that does most of the work (plus he started with a functional laptop!). Discussions I've read usually end with "you'd have to buy a controller for that specific LCD, which would cost almost as much as a regular flatscreen so what's the point?"I reject this (resting on my laurels of ignorance)! If a controller truly exists for every LCD on earth, don't they share lots of common features? And if so, can't we come up with a generic one that could be programmed or dip-switched or soldered or otherwise persuaded to play nice with any LCD on the playground? Even the weird one by the monkey bars who smells like cheese? (Sorry; stretched my metaphor too far and it broke)I envision a circuit board with PC or even TV "in," an amazingly versatile multi-pin adaptor or cable that would replace or connect to that flimsy little ribbon cable sprouting from the LCD. The board would have a USB plug for programming, and a chip smart enough to remember what you tell it. Some smart person will write a nifty app that talks to the board, and vast legions of techies across the globe (or rogue employees of the LCD manufacturers, perhaps?) will upload specs for all of their LCD panels that will be used by other smart people to create a profile for any given panel that can be dropped onto the board.It would have to be really low-cost to make sense, but I envision a cottage industry: package it up as a kit, or we could build goofy-looking monitors out of e-waste and sell them!Somebody else could probably strengthen the argument in favor of this invention by providing a list of terrible LCD ingredients that would be re-purposed out of our trash heaps and water supplies and cat food... I'll leave that up to the experts.What do you think, folks? Is this a pipe dream, or a viable idea? Either way, let's do it!(and if anybody manages to make one, I get dibs on a prototype!)Thanks for reading!Mike

Advice needed on nearly complete instructable

Sorry this is a bit long, but there is an actual question at the end, honest! Every morning at work I walk past a table at the end of our mailboxes that people put give away items on. Its usually a catalog of some form but for a long time now there's been a stack of empty CD spindles and a sign beside them that reads "free to good home." I could have taken them and sorted the mountain of CDs in my office or used them for small parts bins, but to make it areally Good use of empty CD spindles I had to ask myself "IS there an instructable in this?" There are some good ideas for using CDs and a few for the spindles, but at the moment what interests me is hydroponics. So using CD spindles or more exactly the plastic covers they come with I built the basic part of this excellent instructable: http://alturl.com/oa2qt    and I learned a lot of stuff about water pressure and such and once I had built the 2liter bottle method described above I decided to try sealing one of the CD cases and use it for the water container at the bottom of the stack. That took about 4 sticks of hot glue and a couple of burnt knuckles to get a good seal. Turns out there's holes in the center spindle too but I didn't notice them till I had hot glued the container closed. Also ignore the bit of blue air hose inside the container, I was up way too late and flipped the CD spindle 'right side up' which caused me to attach the air hose to the wrong outlet and basically made it useless. I thought I'd need a lot more water in the system than I do so I chose to use a 100ct CD spindle instead of the 50 ct spindles you see on top. (Thanks to all for the ideas on how I could have done it easier!) So far this part of the project was just overlaying the ideas in the excellent instructable above onto the materials at hand. So what I ended up with is an air pump from a fish tank pumping air into the bottom chamber. (the clear hose in center of picture.) This builds up enough pressure to push water thru the blue hose and up to the top CD spindle. I've cut holes the diameter of the air hose into the base of the spindle and this lets water slowly trickle into the Perlite growth medium. When the water reaches the bottom it goes out similar holes in the clear plastic CD cover and starts to pool up a bit to start the process all over again. There is just enough lip on the lid and the bottom of the next spindle to keep it from spilling down the side before this happens. It helps to use the same brand CD spindle all the way up. The clever part of this instructable is that each CD spindle easily stacks in place and you can remove it or change the order without having to dig up or harm the other plants. The base is very stable with several ounces of water in it and I'd imagine you could put 4 of these in a stack and happily swap plants in and out all summer long. The height of the stack depends on how strong your air pump is. I tested two different ones and both were capable of lifting water over 4 feet  up the air hose. Caveat: I haven't actually grown any plants in this yet, so your mileage may vary. Using the stack of CDs for use as apartment planters or sprouting medium would have satisfied the original curiosity for what to do with all those left over CD cases, but in absence of glowing blue LEDs or CO2 lasers I thought Hydroponics would be a great way to sex up the overall idea. I imagine you could use spanish moss or bedding in place of the Perlite, or even soil if you used a coffee filter to cover the holes till you were ready to stick a seedling thru it. This Instructable isn't quite finished as presented. There's a small problem. As you can see in the photo there's a half height (25ct) CD spindle between the water container and the stack of planting modules. Remember that hole I mentioned in the end of the CD spindle? I closed that with a bit of plastic and hot glue, but it made me wonder, COULD I put some sort of check valve here to allow unused water to trickle back into the holding tank YET not lose the hard fought air pressure that's pushing the water to the top of the column in the first place? Since I'm re-using all this old aquarium tech I thought I'd try one of those tiny check valves that keep water from backwashing into the air pump when its off. I'm not sure if it will work in this application or even how much air pressure it will tolerate. This will require some disassembly of the CD hydroponics tower and I thought I'd ask here for suggestions before heating up the glue gun again. So what do you guys think? This has been a lot of fun to think about and I can't wait to bring the media guy  around into my office to see how I've re-purposed the spindles. Just this one last step away…. cheers, flashj
