Dear: Element 14
You should know that my project is almost complete now. All I need to do for my rocket controller is to prototype it and to also to do the electrical mechanical part of the project. See I need to do that and then I am stuck on programming…
Dear: Element 14
You should know that prototyping my PCB is almost finished for my model rocket launcher. First of all today I decided to start a new PCB because my old one was too difficult to work with. Then I had a brilliant idea inspired by somebody…
Dear: Element 14
Hello I have made many changes to my Rocket Controller since you last saw me. First of all I added voltage regulators to my PCB to make my PCB be able to amplify the current to 9 volts to detonate the ignition. Also I have made my PCB…
Hi,
Sorry, this is not a direct Arduino question (but I am building the PCB for a arduino project). I could'nt find a discussion board on designs :-)
I have Eagle CAD 6.3 and I would like to have multiple version of PCBs for my schematic. (To keep the…
Hi,
I'm new to the Element14 community and I'm hoping for some advice. I'm trying to create a prototype for a product idea I have that doesn't exist on the market. I'm a high school bio teacher, so I don't have the knowledge on how to do the circuitry…
Hello,
Me and my friend are mechatronics engineering students. We need to make a project about flow control.
Our university have an aggrement with a valve company. So we can use their labrotary.
We would like to make an electronic card which for see flow…
Hi, I made this schematic for my project of connecting multiple push buttons via TS/TRS/TRRS (mic jack) don’t ask why i didn’t just use TS lets just say check before you buy
. 1 thing im not sure about is the 10k pull-up resistor do I only need that one…
Since I and my friend wanted to start small batch production, we hope to get some suggestion from you guys about SMT production line, including a solder printer, a PnP machine and a reflow oven. But we don't have too much budget, does anyone have any…

Hello all,
well, there is nothing new about using solarium lamps for photopositive coated pcbs and I wanted to do the same. So I bought me a used face tanner even with built-in time switch. In the tests it turned out that the steps of the time switch …
So I spent a rather fruitless Monday printing, ironing, cleaning, repeating, all in a bid to get the toner transfer method to work. I used an HP 7520, printing on photo paper, advertising circulars, and regular 20 pound bond printer paper, (using both…
