@@saileshram7610 still waiting for these small led parts. Once it's finished I'll post pics and a video of where I got all the parts as well as assembling it.
Thank you...Yes, it may seem boring to some, to have someone basically hold your hand when constructing a circuit, but, it does give one the confidence needed if they are new to circuit building and schematic understanding. Especially since most people with diy vids always end up skipping critical steps and just expect people to realize how to build it because they include a schematic. Just that alone will deter someone from building it because of their lack of knowledge and confidence.
Thank you very much for the informative video. Your son was right people do enjoy watching things being assembled. Especially somebody who is a newbie who doesn't understand these things very well. I learned a lot watching your video. Thanks again
You mentioned that this build has drawbacks as compared to your first version. Did I miss the part where you explained what those drawbacks are? Would you mind telling me what they are?
What is the name of that switch, also I cannot find a 37 Ohm Resistor.. And what is the name of the component all the way on the right side @ 5:55 that connects to the LED & 470k Ohm Resistor?
It works! I had had some issues, circuit was not right and needed the correct electrodes. Used the 480 ohm resistor. Runs enough current to burn and create red marks on forehead, so cranked down to about 1ma.
Hello! I just purchased a DIY kit from you online a couple days ago and did not receive a confirmation email. I'm just curious when it will be shipped and when I can expect to receive a tracking number. Thank you
I have been using a TCDC device of my own making for about six years. It certainly has boosted my cognitive abilities. I use a basic small volume control to address controlling the intensity. As a side note, I would add that it seems to actually help with manifesting things. In other words, they say that your thoughts have power. In my case, I give more power to my thoughts. Whether it's related to the documented effect that thoughts seem to have at the Quantum level of reality or not, my attainment of things that I want to bring into my life seems related to the use of TCDS. Consider that possibility. Prayer, meditation, etc. all brought up to another level with the addition of more power...So, be careful what you wish for.
So I'm sourcing parts for this project. Good to Go! Thank you for the prompt. However, that "37 Ohm Resistor" is an awkward single part to find. I can a) take another 100ohm pot and set it to 37 ohm, b) sub the pot and resistor out and fix it at 137 ohm, or c) couple some resistors in series to make up a 37 Ohm equivalent. Do you have alternative configurations for this project using standard, easy to source components? e.g. I can get the Siemens LED but this appears to be a suitable alternative - Knightbridge WP710A10LGD LED; and Trimmer Pot - 3296W-100R. I should mention that I live in China, so these things should be easy to source - but are not.
There is a 10% variance in resistors, so a 36 or 39 are just fine. You can also hit exactly 37 as you guessed by either combining other values or just using a pot. I just put 37 because that was the exact value by calculation... Thanks!
I think there's a typo in the schematic. 7V / 470K = 0.015 mA. At this point the LM334 is doing nothing. To get 2mA, maybe you meant 4.7K? (even that would max at 1.5mA through a short circuit).
I would guess 470 ohm, for max of 15 ma. I could not make out color of all the bands, but assume 47 brown, which would be 470, or perhaps 4.7 k. as you said.
@@ericnelson3365 Thanks for the heads up, where did you get the LED?, the only place I can get the parts is on a Chinese website, but it wont arrive for months.
I would say, .25 watt is more than enough, power = voltage times current, and 10 ma times 10 volt (actually more like 7) would give .1 watt, so this gives plenty of room, as even a short at the output is limited by the 470K, (maybe 470 ohm) resistor.
HELLO AGAIN, HAVE YOU TRIED OUT WITH TMS OR TRANSCRANIAL MAGNETIC STIMULATION ? COULD BE COOL TO SEE SOMETHING FROM YOU, BECAUSE YOU ARE VERY SMART, THANK YOU !
From what I've read... The cons of TMS, The unit is much larger, plugged into the the wall, more expensive, + must be administered by a professional , located someplace other than your own home... Whereas tDCS is much smaller unit , powered by a battery, is a inexpensive unit which is purchased or really inexpensive if you're a DIYer, can be administered by yourself, in the privacy of your own home The caveat is that more research more and knowledge should be obtained for the individual wanting to use tDCS as there's not many checks or balances in place for usage. How cool is that🙄🤣 Use at your own risk. McMurphy would have loved tDCS !🤣
Better to measure it while on electrodes on head, because it is then driving with full load. measure volts across 480 ohm resistor. I = V/R, so 1 volt is about (almost) 2 ma.
@@ericnelson3365 hello what's the value of the resistor is it 470 Kohm as mentioned in the schema or 470 ohm as he said in the video ? If you tried the circuit please
Hi, I followed the instruction but my device gives me 7.8 v and .015 ma or 15.7 microamperes output. I couldn't find whats the problem, LED or the arranger? because I'm sure the other parts are ok. Also, I couldn't arrange the amount of ampere and it's fixed on the 15.7 microamperes.
I think there's a typo - the 470K has the wrong colours, and would result in the 0.015mA max current you are experiencing. I think he meant 4.7K (or maybe even 470 ohms).
I have a muscle stimulating unit, I plugged the electrodes to my head (4 of them) then I put the settings in the (2 1/2) scale for 15 minutes. My assessment: It feels a little uncomfortable through out the whole experience. At this point don't know what to expect from this experiment. I will be doing it everyday for a week them I will let you know what are my findings.
@@Bromar01 thanks a lot.. I also couldn't find low current LED that would glow maximum at 2 milli amps.. Am thinking to skip that as well.. I can check the current directly from multimeter right? So why would I need LED
@@Bromar01 just made it... Am getting 2 milli amps I think it's good enough for tdcs.. Can you provide me a proper DIY schematic for EEG like this one?
Very good video, appreciate all the detail and good camera work and dialogue. I have an issue, wanted to ask anyone who can answer. I built the project, and think it was OK. I put a 470 ohm on the output, and could get 2 ma. However, when I connected electrodes, either direct stick on or with the sponge, I could not get to even 1 ma. To measure live current, I measured voltage across the 470 ohm and calculated current. It should be .47 volts for 1 ma, and close to a volt for 2 ma. I could only get .2 volts. I really want this to work, and I know I probably have something wrong, but could someone who has this working measure actual current with electrodes? My battery measured 9 volts, but maybe it is weak, or something!
If you get all the components he mentions, exactly the ones he mentions, and you learn to solder, and test it all with a multimeter, then you can. Careful though.
Hey! Where's the girl from the thumbnail. Come on, man; the only reason I watched was to see her. 🙃 Oh well, maybe if I make the TDCS, put it on my head, and crank it up to 11, she'll appear in my living room.
