I am looking for a cheap, preferably free, program or suggested work flow to make changes or additions to a STL. The particular interest right now is a small mouse that I download from Thingiverse that I'd like to add a block letter to. Something I'm trying to do for an event at my dog club. I want to print it in green with a block "Q" on its rump. I have windows 7 and 8.1 along with Linux Mint and will soon have an Afinia printer. Thanks in advance for any pointers, Curt

Hey guys, I need help modifying a project. The schematics are provided and i need to keep only the bass part of the color organ (in red). How would I go about removing the other part of the circuit and powering an 16 inch long green led strip instead?Can anybody provide me an edited schematic of the project with the other part of the circuit removed and the transistor connections made for powering the led strip? Oh and someone was saying in the project video that the polarity of a few components are wrong, can someone point that out too? Help will be GREATLY appreciated. Note: If you know that bass is low mid or high frequency please tell that too because i have a feeling that i have circled the wrong part of the schematic. The part I have circled is for low frequencies which i THINK is bass. Another Note: The LED strip is green, 12v, 16 inch long and the flexible type. I dont really know the power consumption but i think that a 1 amp transistor will be enough. (Video Link: https://www.youtube.com/watch?v=wJlglHS2w74) Thanks in advance. -Prickly Potato

I recently got a Vending Bank that you put money in and press a button (1-6) and get candy. The candy dispenses from the holder (small holder mabye 1 inch wide 2inch tall) and it drops down to a slot in the bottom. None of it is motorized in anyway. You can put pennies, nickles, dimes, quaters, and dollar bills in via a slot that you put the bill in and a dial that you spin until the money goes inside the bank. I want to know if any of you can figure out a way to modify it to where you cant get candy until you put at least 25 cents in there because currently you dont have to put money in to get candy. If you need pictures i will gladly supply them upon request. Any help will help! Thanks!

So my friends and I are planning to sell, well...things (I'm not going to give out any details as of now, later) that incorporate small round metal disks. now in all of our prototypes weve used coins for our purposes and they work great. but for what we make we need to cut and sand coins in different ways. and my friends always tell me "its illegal to change money in any way." But I've heard that its only illegal to modify money to change or duplicate the amount its worth - like making a penny into a dime is illegal but making a penny pac man figure isnt. can anyone clarify this for me? I'm fine doing illegal things like modifying coins for personal use but if were going to sell these I want to be a little more clear as to what is going on.

I am currently working on a project that uses polycaprolactone because it has a low melting point and is easily moldable. The problem is once it has been molded and cooled it is sometimes too thin to be as firm as I need it to be and will bend when force is applied. Is there some way to mix the polycaprolactone with another substance to make it more firm without sacrificing much of its moldability or altering its melting point much? If not, is there another material with similar properties that I can substitute?
Question by Sserdna 4 years ago | last reply 4 years ago
I want to build a robot with arduino and for the motors I was going to use some servos that I could modify for continuous rotation. So, I picked up 2 cheap ones at radioshack. I opened them up and I can get to the gears by removing the top part and I can get to the back of the circuit board by taking off the bottom. But the circuit board is soldered in so I can't take it out to get to the potentiometer. I tried desoldering the connections to the motor but there seems to be more joints to desolder before I can take out the circuit board completely. And I don't want to desolder every joint and then have to solder them again when I need to put them back together. So has anyone modified these radioshack servos and can tell me how to get tho the potentiometer? Or can anyone tell me if there is a way to modify them without getting to the potentiometer? Thanks.

Topic by ottkosmoses 11 years ago
I apologize in advance for the complicated question, but here we go. I have wireless puck lights that work off either pushing the top to click on, or a wireless switch. The switch only controls on and off, no color control or brightness. The lights run off 3 AAA batteries per puck. My problem (which seems to be the most common problem with these puck lights) is that they drain the batteries even when off. I have a feeling the drain is due to the wireless antenna staying open to receive the signal from the switch. I found using a 5V USB plug powers them fine, but I don't want any draw to occur when the lights are off. So my 2 questions are... 1. Has anyone encountered a device like this and found a way to disable or even remove the wireless antenna only allowing the LEDs to work off the internal switch? 2. Does anyone know a way to bypass the switch so the lights are powered when power is present? My goal is to have the lights run off the 5V adapter with an inline switch to control the line up. vs. clicking each light on one at a time. I have attached images of the board top and bottom, also the lights are "Lightmates LED Wireless Puck Lights" notorious for eating batteries.
Question by NathanA52 2 years ago | last reply 2 years ago
Briefly, my lawn is a mess and I cannot afford either an electric rake or dethatcher. I have tried using a spring-tined rake to dethatch the lawn but it is too labour-intensive - and I have around 250m2 to cover - not for the faint-hearted! However, I do have a petrol rotary lawn mower and a spare blade. I have thought of combining the spring-tined rake to the blade to dethatch that way. I don't mind the thatch not being collected - as I expect it will leave the mess on the floor - I can simply dethatch at a higher blade height and then cut/pick up the mess on a lower blade setting. I don't have a welding machine, nor access to one. So I wondered if the good people here might lend me their brain cells to consider (a) what I might use as a rake on the blade and (b) how to secure it on to the blade. I have seen one of those rakes which can be spread at will and I thought to size it and secure it with a metal band and rivets - and then rivet the whole thing to the blade. What do you think? I had also thought that I could fix the rake on the opposite side of the blade. The blade is not reversable/obversable - there is a one-way key that oreints the blade to one position only. Please do not trouble yourselves with warnings about safety etc as I think I am aware enough to consider this for myself - unless it is to say "don't do it". I also know about having to balance the blade weight. As ever, thanks for reading me and thanks for your time to reply.
Question by kevinhannan 7 years ago | last reply 6 years ago
I'm currently designing an accessory for my computer which will house 4 USB ports as a USB Hub. The issue i've got is I need to be able to contain the whole USB Hub in an area that is only 22mm deep and 170mm wide. I've taken a cheap USB Hub apart to see what it was like and I have run into a few issues. The main one is that the total depth of the PCB to the end of the USB Ports is 35mm, 13mm over the size I need. The next issue is that I need room to place a screw between the USB Ports, 2 either side. These screws have a width of 3mm and a head size of 5mm. Putting a hole like that in the PCB would break and short the connections. Does anyone have any suggestions?

A while ago my wife got one of those singing Hallmark greeting cards. (This particular one played the Law and Order theme song) Well after a while it no longer played the song. I opened it up and found that there is a circuit board inside with a 3v button cell battery attached to it. I removed the board and the speaker and the battery and I'm pretty sure that I could attach wires to the two contact points and connect them to batteries that would complete the circuit and allow the theme song to play again. What I want to know is if I need to take any special consideration when putting in a new battery(s). I was going to try to just put two AA batteries in series (1.5v +1.5v =3v, right?) but I don't actually know anything about electronics and so I wanted to ask here if there were any resistors needed or if there were any differences between the button cell and the AA batteries that would require me to do something different.While we're on the topic of these cards I just thought of a neat project. Design some sort of holder for the circuit boards that would allow them to act as sort of an interchangeable cartridge. Basically detach the speaker wires and battery contacts from various boards out of various cards and design some sort of holder with contacts for the speaker and power source at the appropriate points and be able to change out the different boards. Not really practical but sounds like fun.I just thought of yet another question!Would there be anyway to hook the board up to some sort of audio cable (in place of the speaker maybe) so that I could plug these into a computer and record the song off of the board in a digital format. (Again not very practical but sounds like fun.)Anyway, this is my first post here and I'm sorry if it's a bit jumbled but I don't have a very organized mind and sometimes it's hard to put my ideas down in a succinct manner. I tend to just ramble on incessantly in a train of thought sort of manner until I think that I've said what I think I wanted to say. In closing, I like this site and plan to be around for a while and learn as much as I can. If somebody would like to help me with these ideas/projects I would be happy to provide pictures of the circuit board and pieces that I have if it's necessary.Thanks.~JoshI'm using two AA batteries. I have a wire between the positive side of B1 and the negative side of B2 and wires coming off the open ends. I tried connecting the batteries from the spot where the negative side of the button cell was to the silver rectangle thinking that that would complete the circuit and make music. That didn't work. Then I noticed that the positive connection for the circuit was actually where the clip that secured the battery was before I removed it and that the positive and negative sides of the battery were going through a capacitor before touching the final contact. so I tried placing the positive wire up on the positive contact and then placing a wire from the positive contact to the final contact but that also didn't work. I don't have any solder and have been using electrical tape to secure the wires. The wires are a fairly thin (I don't know the gauge) stranded copper. I'm not sure if the wires aren't making good contact or if I'm just doing something wrong.

I owned a tablet PC - fujitsu T4010D and after a while, I had to stop using it - as I've gotten it USED, and I stepped on it as well (lol I'm a klutz, yeah..) it began being a danger to use. Between the previous ans current issues, it would spark, etc. etc. A few months later my main tablet, my intuos3 died on me so I have no tablet at all. So I then thought - would it be possible to convert the digitizer and everything in the tablet PC and simply turn it into either: A: A screen tablet (like the Cintiq) that would work with another computer or... B: Simply a regular tablet for another computer With option A, I'd assume there would be the annoying process of getting a digitizer (unless it can be utilized from the current laptop) and everything. I asked that a while back and I was told it's sort of not worth it for making another screen. With option B... I really don't know if there's any way of doing it. Overall, having a screen tablet that uses Wacom's technology is nice, without the $2000 price tag it holds. In the case of having a general tablet, if it can be done without spending $600-$1000 I'd like to try my hand at it... ...Is this even possible, though?

I was hoping to hook it up to a WeMo switch so that I could turn it on/off via Google Home, but the fact that its a soft power button means that even if the switch turns on or off, the radio doesn't remember what state it was in last. Is there a way to modify the circuit board so that the receiver is always on and thus, I could control it via the WeMo switch? Thanks in advance, Tim
