spanner888 writes: Finally got prototype working and have captured over 90,000 frames with promising results. Noticed along the way that SMD component tapes fit the 16mm film sprocket really well, so there is food for thought! Documenting an outline of build and all the useful stuff from around the web that helped me out on […]

Use sublime text 2 to replace Arduino IDE
Kathy Yang over at Elecfreaks writes: We could often feel frustrated when programming using the Arduino IDE. Why? Not because of how many errors we encounter in the program, but it is so difficult to find out the errors in source code, which is really something freaking out. For example Arduino IDE does not seem […]
ytimer, visual feedback timer
Here’s Aon’s finished project the ytimer a visual feedback timer. We wrote about it previously: A countdown timer with super bright 7-segment displays that flash when the time is up, instead (or in addition to) an audible alarm. The design is based on a PIC16F886 microcontroller which drives the displays using a TLC5916 LED driver and dual […]
Stack of dirty boards arrived from DirtyPCBs
NsN share his dirty boards from DirtyPCBs, this batch includes: Flash and Camera trigger A basic Attiny25/45/85 breakout board An attiny based I2C Infrared emitter / sender A bluetooth breakout board An USB cable quality tester Via the forum.
120 seconds voice record – play back
A message recording board capable of recording 120 secs of audio by Rajkumar Sharma over at Electronics Lab: This project is designed around ISD25120 which can store 120 Seconds audio. Recording and playback operations are controlled with tact switches. The kit has an onboard microphone and LED to indicate the functions of Play and Recording. IC has […]
DirtyPCB IKEA Samtid mood-light upgrade
madworm writes: Just wanting to share one of my latest projects, made possible by DirtyPCBs. I got a lot of good boards (actually 2 designs) and saved 25$ using this service. Very nice. It’s a simple thing, just a micro (ATmega168) + a bunch of WS2812B LEDs. Main purpose: more colours :-) It’s meant to […]
Burn c into other chips using Arduino Duemilanove
Kathy Yang writes, “We may often encounter such situation as bootloader falls off when using Arduino, this thing can freak us out especially when we got no bootloader tools on hand. So what shall we do? Here we’ll introduce a way on how to burn c via Arduino, which is rather practical in cases when without […]
DirtyPCB Charliecube
kjetilei shared his Charliecube project, inspired by the instructions provided by SobiGuy at SobiSource: I showed the cube at my local makerspace and proposed a build day. The interest was high enough to bulk order the various items needed for 10 kits. Just before ordering the batch of protoboards I started to think about making […]
Arduino GPS map navigation system
Kathy Yang of Elecfreaks writes: Built on the basis of Arduino UNO, GPS, SD card, TFT, GPS map navigation system is to obtain the real-time position information via GPS, to send it to UNO for calculation, according to the calculating results, and teamed up with the map file stored in SD card, thus presenting the […]
ytimer: Visual feedback timer
Here’s an update on Aon’s boards from DirtyPCBs we covered earlier, a visual feedback timer project: Here’s what became of one of the boards after a bit of soldering and programming: a countdown timer with visual indication of when the time’s up instead of an alarm (there’s a place for a piezo buzzer on the […]
Got something dirty in the post today from DirtyPCBs
Aon posted pictures of the boards he ordered from DirtyPCBs in the project log forum: Just received these boards I ordered from dirtypcbs.com two weeks ago. Came with complimentary tweezers and all :D Also received a USB microscope today, so here’s a close-up of a SOT-363 package and some 6 mil traces. The silkscreen seems to be […]
DIY shake LED Stick
Kathy over at ElecFreaks shares his DIY shake LED stick in the project log forum: The principle of shake LED stick is based on that people have persistence of visual senses. When you light up a column LED at different moments in different ways, shake it, and a very beautiful picture will display before your eyes. […]
Tiny waveform generator
herpderp shares his waveform generator in the project log forum: Here is my last project, a tiny waveform generator based on my previous project and some components: – An AD9834 (DDS chip with sinus/triangle output) – 2 x AD5310 (10bit DAC: one for the Vpp control, another one the offset control) – 3 x LM7171 (Fast […]
Yet another DirtyPCBs in the mail
snikrepmada posted pictures of his SMD protoboard v2 in the project log forum. He writes: Just got a stack of Dirty PCBs in the mail today. The quality is spot on, no problems at all, these are the best value PCBs anywhere!!! These are my own revision of the SMD prototyping board. I’ve got to […]
