Teletypeguy posted a simple how-to on making chassis overlays with a Cameo: After finally getting stencils working with my Cameo cutter, I wanted to try making chassis overlays. Over the years I have spent good money getting polycarbonate overlays (7 to 10-mil) with rear silkscreen for connector identification and such, a flood-fill color, backed with […]

Cutting a stencil with Silhouette Cameo
2blmaster shares his experience cutting a stencil with gerber2graphtec using the Silhouette Cameo: I just received my Silhouette Cameo after I got excited reading *this* thread :) I use it together with the great gerber2graphtec tool In principle it works as expected and according to what is promised here :) But trying to print “large” […]
DIY 3d laser scanner
Alessandro Grossi developed this DIY 3d scanner. The primary ingredients in this project are readily available and include a line laser, an Arduino, stepper motor, stepper motor driver (up to 12800 steps), 12V power supply, IR LED and a digital SLR camera. While he wrote the image processing script for Matlab, he notes that it […]
DIY Daft Punk helmet using a Raspberry Pi
Ryan Longo and Michu worked together to make this cool DIY Daft Punk helmet with Raspberry Pi – software by Michu, the idea and hardware by Ryan Longo: So I wrote a Netty based Java application using Pi4J which does exactly this. The UDP2I2C source is published on GitHub My application receive UDP data in the […]
Double sided PCB etching using a laser cutter
This video by Rich Olson demonstrates his method for creating 2-layer PCBs using his laser cutter and chemical etching. Via Hacked Gadgets.
Solder stencil using Shapeoko
Peter used a Shapeoko to cut a solder stencil for a Sick of Beige Bus Pirate v4: I purchased two Sick of Beige Bus Pirate v4 from schazamp on the DangerousPrototypes forums a couple of months ago and have been dragging my feet assembling them. I used hand soldering for the SMD parts on my […]
Notacon 10 – DIY Neuroscience, EMGs, EEGs, and other recordings
In this presentation from the recent Notacon 10 conference in Cleveland, OH, Karin Halsey (aka meecie) provides a thought provoking roundup of the tech basics behind medical sensors and related devices. The talk focuses on working with basic supplies and DIY kits to measure biometric information.
DIY wireless data transceiver
Build your own wireless transceiver: Have you ever wanted to send data from a sensor or project wirelessly? This simple circuit allows you to build your own wireless transceiver using two ICs, a transistor, and two resistors. The IC is from Melexis and uses On-Off Keying modulation and can be battery powered. Via Electronics Lab.
DIY 3D printed stepper motor
Christopher Hawkins made this cool DIY 3d printed stepper motor: This is a programmable stepper motor and driver that I made out of some nails, magnet wire, neodymium magnets, a digispark microcontroller, and a 3D printed piece that I designed around these things. My goal was to make something about the size of a business […]
AquaPinguino project
Here’s an AquaPinguino project by Susanne from Germany: She has built a system with automatic monitoring and control of every major water and lighting factors for her seawater aquarium. She made a double side board controlled by a Pinguino32 Micro with relays on one side to control lights and mosfets on the other side for […]
XBOX 360 controller rumble light effect mod
Viktor added cool light effect to a translucent XBOX360 wireless controller: I didn’t want to use an arrangement where the lights would be on for an extended period of time, because that would lead to very short battery life in the controller. I also wanted this mod to be very easy to make, without microcontrollers or other […]
Homemade wristwatch – DaTajm
Mats posted his homemade wristwatch – DaTajm in the project log forum: DaTajm is a wristwatch based on a PIC16F1824 powered by a single CR1216 lithium coin cell. I’m using a sandwich of three PCBs. The topmost pcb (0.8mm thick) have 12 leds and a resistive touchpad on the top side and all the other […]
AZIZ: DIY LED microscope illuminator
Here’s an interesting project by Steve of Tangent Audio the AZIZ project, a microcontroller-based LED microscope illuminator: AZIZ is an LED microscope illuminator that I designed and built from scratch. It is designed around a Texas Instruments TLC59116 constant-current PWM LED driver chip, and an Atmel ATTiny1634 8-bit microcontroller. Check out the video after the break.
DIY AVR Atmega dehumidifier controller board
Davide Gironi documented his DIY AVR Atmega dehumidifier controller board build: Suddently my dehumidifier stop working, the original humidity switch get broken, it was a mechanical hygrometer, based on a thin transparent strip that react to humidity and engage the main electronic switch. So i decided to build my own dehumidifier board.
Simple DIY ECG + pulse oximeter (V2)
Scott Harden has designed an ECG/pulse oximeter combo project using LM324 op-amps. Scott describes, “This new project is fully documented and uses extremely common and cheap parts, all of which could be purchased at RadioShack. It serves as both an ECG *and* a pulse oximeter, depending on which leads are attached. It uses a single […]
DIY USB Infrared Toy
Mike writes informing us of his DIY IR Toy: Finally got around to taking some pics of a DIY IRToy I finished last week. All the parts are 0805, since I don’t have an 0603 kit (yet). I have it working nicely on Linux with a patched lirc, with both transmit and receive. I’m currently […]
Vacuum former project
Here’s a 3D printed vacuum former by Jonny, documentation is available as a thing on Thingiverse: This is a vacuum forming machine that you can print. Which allows you to make a mold of your 3d printed object. I hope you like this and make one, you’ll be able to pour chocolate in your mold […]
Hot-air rework station repairing
Oakkar7 shares his experience repairing his hot-air station: I quickly checked the problem. There is no air flow at the nozzle. But I still heard the air compressor sound. Today, I tear down and find out the problem. My rework station is a cheap china made, LK852D brand. Here is what inside.
The 3D printer controller
Matthew of Electronics for Humans has been working on 3D printer controller: The design is based on an Atmel Atmega328 running at 8MHz (using the internal clock) at 3.3V. This is in order to keep the same voltage as the main controller board, which will be powered by the LPC1768 that only works at 3.3V […]
