I forgot to mention the OH produce a lot of cobalt (II) hydroxide and some of it attacks the metal and the residue of HCl slowly forms copper (II) chloride hydrate.

Yeah I have that similar radio I may give it a go sometime. Cool instructable.

Many of the 130 in 1 Science fair had Dual Op amp and used an earpiece to ampify sound through two Op amps and a speaker and some resistors. That reminds me of this. Cool Instructable tho!

That is very neat Ebay sells simple tube radios for 300 dollars or more but I don't know about the quality of the sound tho.

Yes but where and would they work? Would there be issue with Canada?

I tried a project with Potassium Nitrate and Hydrochloric acid and heated them on a good hotplate. The Potassium nitrate fell to the bottom of the flask and would not heat well with the HCl. I recommend a gas trap and Magnesium Nitrate in HCl to make Aqua Regas with this Method.

Perhaps more Quantum dots could be made by modifying the acid and base part. First, you add the sugars and then the appropriate amount of water with HCl (for this example) and heat to 60 degrees C then cool to 40 degrees, and add potassium carbonate. After cooled stir again and heat it up to 60 deg C to get more dots to form. This is only Optional but may give better results. Let the solution cool to room temp before using the Laser.

You know you can buy a lot of chemicals safe and unsafe including thallium off eBay. I would recommend thallium or any heavy metals but I get lots of chemicals off e bay and amazon. They include dyes and natural pigments from plants and trees. My distillation apparatus comes from China Ebay too. Buy a good hotplate from a good lab manufacture for 500-1000 dollars if you can afford it. They are amazing stirrer and hotplates.

Sounds like a cool and neat Idea for people who want a forge.

Neat project to try to make. You can easily buy most of the material on ebay and try it with a hotplate and glass (distillation like material) I think.

Another useful application storing radioactive material in small mounts like what you made. Hmm lead cans etc could block a lot of pitchblade ore etc.

Neat an Hydrogen fuel cell could be a next project if you could collect the Hydrogen and aford Pt or Pd material. Collecting hydrogen like that sounds so cool.

Curious how does the sensor work is it an IR diode or laser with a Photo diode detector? Still that a cool Instructable. Very applicable.

Very cool to see a NOT gate and MOSfet gates run a DC motor.

This sort of reminds me of a battery opperated magnetic loop ant which uses magnets and diodes to produce a signal with a magnetic loop but obviously it very different than your application. I like this instructable what could you charge with a few volts? Your cellphone?

That interesting what the max voltage it can handle?

Very neat to see those mirrors and stuff reflect the sunlight and heat water to steam. It a very Impressive Instructable. Essential Oil from solar Now that is cool.

Some dried spoon results that look like dark Oak.

Wow, I like the setup and how it is presented so 200-300 deg C. Hotplates can be very expensive to buy 100 of dollars more if you need stirring. So you are going to modify this with more ICs like the temperature detector?

Rit dyes (Scarlet), Rit Golden yellow and Crystal violet and Malachite green Inverse rainbow.

Ebay sells good 405 nm lasers make sure they are retuiable and have a fan and a heatsink. Most operate 20 min on, 3 min off. I use 100-200 mw lasers 405 nm for dye stuff. Cool Instructable.

Hmm 355 nm Q switched and 256 nm Nd Yag triple and 4th frequency dividers (crystals) are very expensive min 5000 dollars to 50 grand. It depends on what you doing. If you want to do dye lasers than 337.1 nm (Nitrogen laser) or Q switched 355 nm lasers if you can afford it may be worth it. A cheap but decent 200 mw 405 nm is recommended for hobbyists that just want to play with lasers. Oh make sure you wear the proper safety glasses for the specific laser.

You can also add Phosphorous materials to tubes that under Pulsing and regular UV light glow different colors. Glow in the dark Materials 30 ml you only need 1 ml of each tube.

Rhodamine B with 4 ml of 4 g of Ammonia carbonate in 1 L of tap water with 405 nm and 532 nm laser light. Just some ideas the base shifts the Rhodamine B which depending On the OH- or H+ forms two isomer molecules.

With the laser on the beaker and the plastic sheet removed this is what the tube effect of laser beam on 6 tubes is. Yellow= Sodium fluorescein, Pink = Rhodamine b salt, Dark blue= Stibline chemical in dish detergent, Green = Palmolive soap and Light blue tonic water.

Interesting concept for CRT type TVs. I wonder if there is anyway to hack a super scope 6 system so you can play on a flat LED screen. Maybe it the rapid phosphorous Red, blue and green flashes that actives the super scope sensors.

Really like the idea of converting a fitness monitor into a spectrometer with a led to measure bacteria samples. Well a photometer is more prcise.

That is awsome that the kind of thing we would do In biotech years 2 to final years. Keep up the good work.

Well, that a very cool idea making a radio with Arduino that is solar. It seems quite complex even tho I understand most of the skamatics that you provided.

Well, I live in Quebec Canada I can get at 4 am to 6 am when it dark and less stations are present and the radio waves bounce to my reciever lots of US stations like from Florida or Texas which is amazing. Have u ever considered building a long short wave radio like as a Kit? I use a Normal magnetic loop to get better reception. Lots of US stations on the Medium range.

I just made Copper ferrocyanide pigment Cu2Fe(CN)6 H20 by adding 8.6 g Potassium ferrocyanide and 10.42 g of copper sulfate to 200 ml of tap water. Mix the Potassium ferrocyanide with hot water first allow it to cool to room temp and add the copper sulfate it will get a bit warm.

I always like Projects with solar cells and Radios. Is there any way of completely making this Radio waterproof? Cool concept and a lot of good hard work in making this Radio.

I always like Radio and longwave and short wave radios. 72 volts across a tube and other voltages to amplfiy it Nice job here.

Please see my Second Instructable on Artifical Pigment for Painting. It quite unique.

Most of the Pigments (Elderberry, Beet, Cabbage powder, and Madder root powder) can be bought on Amazon.ca. Glassware can be bought on eBay, most chemicals like Alum (eBay) and the alcohol (Some grocery stores and Pharmacies). Tween-20 can be bought by local suppliers on eBay. Good hot plates you may need to buy from a Science company (they are Not cheap 500-800 dollars minus shipping!).

Yes, randofo you could use alcohol for the dyes but stronger stirring and you would need at least 500 ml of ethanol or isopropanol alc at 70-99 percent (Not cheap due to cov19 in Quebec but can be done). If you buy the beet extract do not boil it and distilling at 30 degrees Max is strongly recommended. All these dyes are Not stable so storage at 4 degrees even with 5 ml of tween20 is recommended.

I really like the idea but I am concerned about the Carbon output since you are burning wood to produce heat to breakdown the bones. Is this an efficient process?

Note smaller concentrations may work too like 13 g tin chloride and 10 g of lye but it less likely due to concentrations of tin Hydroxide in Lye to produce tin crystals.

Very cool idea sadly I could not afford this stuff even at my salary at work or Home use. How long does this type of Phosphorous Light last? An increabibly impressive Instructable BTW.

With a saltwater capacitor and a Proper transformer, you can make a bigger plasma. Here a video. https://www.youtube.com/watch?v=ITJSD5yLL30

I usually buy kits or beta, gamma and x ray devices pre made. However making them is a very cool idea if you can with the electronics and programming. Cool.

I tried this with soil bacteria graphite rods and salt and bacteria. It worked at first but produced very low voltages and I tried amplifying it with a DC to DC converter. It failed. Even graphite-aluminum soil batteries gave semi good results. However connecting 3 batteries increased the resistance to enough that the DC converter could not opperate. Difficult to scale up but possible.

Yes, I heard Nurdrage made a similar cell. It quite cool but is it practical you can buy mini solar cells. I heard for big solar they use Lithium or Vandanium technologies to store energy and release it when not needed. Cool Instructable.

A brown iron +3 DMG which is different than Iron (III) chloride from Iron sulfate 3.5 g and 100 ml water with 4 ml HCl is added to 3.5 g DMG with 100 ml Isoproponal alc. Then 20 ml of conc ammonia is added.

Diposal of hazardous chemicals like DMG-metal complexes is very critical. Wear gloves and PPE these complexes are dyes and are Irritating and toxic. Especially the Nickel DMG complex.

Your Instructable is very Interesting. Here in Quebec, you need an expensive permit to own bees and you can get in trouble like the Neighbors must know that you are doing this. It seems complex. I have a back yard of sweet white clover that is perfect for Honey bees and bumblebees and also I have a few wasps too.

In terms of sporing bacteria, each metal acts differently. Copper is absorbed by the bacteria and any excess Na+ and formate form a basic condition on the outside of the cell. A little of the copper is found in the spores but mostly in the bacteria. Copper formate forms due to reaction of soluble copper due to bactera and sodium formate. Manganese dioxide forms differently the basic condition does not form a green Magnasese formate but a Magnasese salt Mn+3 due to basic conditions.

It got reduced by the bacteria.

I assume for Magnanses, copper, Nickel and even Potassium Orthvandanate that the Bacteria absorbs and uses Sodium formate and produces Na+ as well as Co2 in the cell of the bacteria spitting out Na2CO3, some K2CO3 (in the case of the vanadium) and converts the metals by bacteria enzymes and Alkanic conditions into other forms.

Well making a home reactor even tho it is complex to produce medicine is cool. We tried growing algae for projects in Biotech to make biodiesel it took 1 month to grow it. Here an Unknown algae that could be dangerous that I wanted to grow in cultures.

A snaps ant coil would work well not as well as the 130 in 1 ant coil but if you cannot find it you can order parts from ebay.

Sure. R1 was 460 Kohms and R2 was 1 Kohm. Coil was from 130 in 1. You may need an old coil or an 130 ant coil from the 130 in 1 to get this to work.
