Which delay should I get boss DD-7 or MXR Carbon Copy?

The cost the same. The Carbon Copy is analog, and the dd-7 is digital.

ear bud case - delayed instructable

I posted an 'ible on creating ear bud cases out of a contact lens cases. However by the time it showed up on the recent-instructables list, it was already on page 7. If you are interested here is the link.https://www.instructables.com/id/Ear_bud_case_from_a_contact_lens_case/

When will they post the RoBo contest winners?

Will they ever post who won the RoBo contest? They delayed it 3 times and will be mad if they do it again.

Help with building Disco lights please?

Does anyone out there know how I can get 4 coloured flourecent tubes to come on instantly when connected to a 4 channel disco controller? There is a delay I think because of the starter in each fitting, but i am sure someone will know how to over come this! Thanking you. Steve Stehenrobertson1@tiscali.co.uk

What is a good way yo make a firecracker from caps, without needing to break individual caps apart?

Yeah, the title just about says it all. I have made ones that you smash with a hammer, but I want something that I can set off with a time delay (Fuse). Thanks!

Why is the downloaded PDF outdated?

When I click on Download PDF at https://www.instructables.com/id/Spin-Art-Machine-Kit (an Instructable I created), it downloads a version of the Instructable with older photos and content.  I thought perhaps there was a delay in updating the PDF but I waited a day and it still is happening. As an example, the third page of the PDF (Step 6) shows alligator clips attached to a slide switch.  But in the published/online version of the Instructable, Step 6 shows a slide switch with wire leads.

Knex Gun: Infinity

Hey guys, sorry about the delay. I've been really busy with school, since I'm a senior, gotta keep working and getting good grades and what not. Anyways, I have the pictures for the Ible ready, just need to upload em.  Just give me a little more time. Thanks for always being there, and supporting me! -SW- P.S: There has been several modifications since the video, they will be in the Ible, and I warn you, it is not an easy build, and it requires quite a lot of pieces.

Published instructable does not show up on the site or in searches. Answered

It even is tagged as 'featured' but it does not show up under the category (play) or at the relevant keywords (nintendo). Also a search on the exact title does not bring it up. You can basically only reach it if you know the url: https://www.instructables.com/id/Plush-Super-Mario-Block-with-Sound/ Is this normal, is there some delay? Published 15 hours ago, just before the maintenance of the instructables website. Please let me know if I should just be patient or undertake some action ;-) thnx

Knex build challenge!

Build a knex gun that doesnt require any green rods and is a true trigger.... Are you up to the challenge? 1st place - A preview of some of my knex guns and knowing that you got first place 2nd place - Knowing that you got second place 3rd place - Knowing that you got third place Note: preview may be delayed because of my cameras that have been shot and destroyed by my knex guns..... Due to terrible accidents so preview will be delayed for a very.... very LONG TIME Im gonna get a camera that wont break hopefully and takes beautiful pictures ;D! Hopefully one of my knex guns or oodalumps cannon modded by me doesnt misfire when i drop it again.... That WOULD SUCK! I cant take new pictures of the modded spider massacre v 3.0 cause of the description above so... look at drummerians crossbow... ish ... ? sorta not really I made two so i decided to turn it into a sniper ish thing? o well its an old picture if i remember correctly...

Arduino Mega WaiveShield 48 Button sampler (Advice ?)

This will be my first project, and original reason I found Arduino in the first place! I was searching for an affordable portable music machine. What has developed in my mind has become progressively bigger, but  I digress. I currently have 2 Mega 2560's, Wave Shield, and an assortment of switches, pots, and buttons robbed from "trash ?". In the mail as I type is a Beat707, QuadRam, R.C. MIDI Shield, Mux 2 Shield, 3x 555 Timers, and a  PT2399 delay. My plan of action was to beef up one mega with the quadram, waive shield, MIDI shield, and Mux 2. If this is possible, it would make a 48 Button sampler with SD card slot, MIDI in and out, and just maby 8-10 bit recording capabilities? Mean wile take the timers and delay and create a funky sounding distortion box that can be positioned anywhere in the circuit. The second Mega is dedicated to the Beat707. Question being, what do you think? I have tons of hardware experience, and soldering hours under my belt, but programming is a new one for me. Im not sure how to judge if the Mega will stand up to the challenge of the first combination, but my biggest requirement going into this, was I wanted something portable, that ran off batteries, but was not just a toy. I started calling it the pocket studio, although I doubt it will fit in a normal pocket.

New K'nex wheel design

I've been working on a new ball machine for a few years and finally decided to tear it down and start anew; one thing I did save was this wheel. It uses chain for a rim to make a "perfectly" circular wheel. With grey rods on every rim connector it is quite heavy, in my ball machine I used a delay to send 3 balls onto it at once to make it spin nicely. If you want you could only use once white connector and 8 grey rods to make a lighter frame that would spin well with only one ball on it. Peace! ~IaC

Fitlight trainer using arduino

I want to make a fitlight trainer with arduino. I want to make it with leds and LDR ligtht sensors. A random light pops up and when you hover over the sensor it sets it to LOW and then another random light pops up and over and over. Can anyone help me with this idea? I have the code for one light: int LDR = 0;     //analog pin to which LDR is connected, here we set it to 0 so it means A0 int LDRValue = 0;      //that’s a variable to store LDR values int light_sensitivity = 20;    //This is the approx value of light surrounding your LDR void setup()   {     Serial.begin(9600);              pinMode(13, OUTPUT);      } void loop()   {     LDRValue = analogRead(LDR);      //reads the ldr’s value through LDR     Serial.println(LDRValue);       //prints the LDR values to serial monitor     delay(50);        //This is the speed by which LDR sends value to arduino     if (LDRValue > light_sensitivity)       {         digitalWrite(13, HIGH);       }     else       {         digitalWrite(13, LOW);       }   }

Ok, thank you to all who helped me "search myself".....

I FOUND IT ! After MUCH soul searching, I finally found my trigger and it is NO WONDER I was having a difficult time "coming to this conclusion" it is because the trigger itself was preventing me from admitting the trigger to myself LOL I think I shall go and Irony some shirts now ;-) FEAR ! The great negative motivator. I had failed at a few projects, and feared starting ANYTHING, for fear of another disappointment. Now, it really is simple; I came to this when I realized I was starting to come out of my depression, but not all the way, and was preparing and preparing, and gathering "intelligence" and info, but still delaying the start of the project......I always needed more INFO but only because I feared having the whole thing FLOP. It came to me this morning and I felt relief that NOW I can move past that, and get to work on changing it, because I have never feared failure in this way before. But then, I am getting old and doddering ;-)

Can a cracked guitar neck be fixed?

Hi, I finally signed to Instructables. :) My colleague is a big DIY guy and that's how I came across Instructables. Today, while searching for something I came across homemade recipes for musical instruments and that really hooked me on. Especially the one on turning an 6-string acoustic to bass acc. :) I had tried learning the guitar but didn't want to spend too much on the instrument, so I bought a second hand one from a garage sale (proceeds were for the city's stray dogs - so for me it was a bit of a win-win...almost :) ) What I realised much later is that: 1) The wood under two of the tuners (on the under/ventral side of the guitar) has splinters 2) One of these tuners has lost a fastening screw because the hole in the wood has widened and splintered a bit 3) the base of neck, just before the curve block that connects to the box, has a 1-2mm crack running across it (horizontally) Question is, can these issues be fixed so that a beginner like myself or someone who really doesnt have the money to own a guitar but wants to learn can still use it for some time? I never found the time to go to a music shop to have it checked. I also feel they will probably turn me away because they are more interested in selling guitars than fixing them. I really dont want to just throw it away. Second hand it may be, it just doesn't feel right... Your inputs would be greatly appreciated. Thanks! P.S.: Am at work right now but I will try and post images of the guitar as soon as I can. I had taken photographs of it a looong time ago. As a result, tuning goes off every now and again. On a colder day, tension increases and the crack widens. Update: Terribly sorry for the delay in uploading the pictures. I had a set that I had taken a year or so ago but I seem to have deleted them. Just got some time off work, here are the pictures. The crack, which I had earlier described as horizontal, is in fact, vertical. So much for my memory...

IF......

Hey all, I just wanted to give a shout out to anyone I might have indicated (unintentionally) that I was treated poorly by you all in any way....I don't see that at all.   I  don't always get fair treatment at home or in my personal life, and so the way I word things can sometimes spill over into sounding like I mean this group....I don't. As I have said in the past, I was sinking into the oblivion of depression when I found this site, and it helped me get "help", so I could again, focus on "making,  remaking, repurposing" things....my inate love. Thank you all once again.
