Aliexpress Timegrapher

 

 
I recently purchased an inexpensive timegrapher off of Aliexpress, in order to improve the accuracy of a watch that has been losing considerably more time than my other watches. The included instructions are in Chinese which was less than handy, fortunately there are numerous tutorials on YouTube on using a timegrapher. You can use it with the Android app
 TICKOPRINT  

It also works with the Windows program TimeGrapher TG 


although I had to go into my system settings and adjust the microphone volume all the way up in order to get the windows software to work.


 If you are still having problems, there is an internal volume potentiometer connected to the op amp. Adjusting it as pictured increases the volume. To get access remove bottom pads and the 3 screws on bottom.

Here is a link to the timegrapher guide I am using to attempt to fix my watch.

Force Phone View: Firefox Extension

If you’ve ever tried to browse the web in split-screen mode on a small laptop, you know the struggle. Most websites stubbornly cling to their "grid" or desktop layout, leaving you with tiny text and horizontally overflowing content. Force Phone View is a Firefox extension designed to fix exactly that. By tricking websites into thinking you're on a mobile device, it forces them to deliver a clean, column-based mobile layout that fits perfectly into narrow windows. Key Features Mobile Spoofing : Automatically sends an Android User-Agent to ensure the site delivers its mobile-optimized version. Width Constraint : Constrains the page viewport to 720 pixels , a width that reliably triggers column views instead of desktop grids. One-Tap Control : Toggle the effect on and off instantly using a simple button in the Firefox extension popup. Enhanced Readability : Perfect for researchers, students, or anyone multitasking in side...

Arduino FM Radio Transmitter

This following is re-post of an article from my old blog from 2008: This is an FM radio transmitter I made using an arduino and a NS73M FM Transmitter. I got the idea from an article on hack a day, if you’re interested in building your own you should check out Mike Yancey's page he built the one that made it on hackaday.com and he does a very thorough job of documenting how all the components hook together. I was impressed by the level of finishing he was able to achieve on the housing; it looked like a commercial product. I wanted to see if I could achieve a similar result, it’s amazing what you can do with some simple hand tools. If your patient with the file, you can make perfectly square holes in aluminum.   On my implementation I omitted the de-bouncing circuit that he has connected to his rotary encoder, and I used a two-line display. Since I omitted the de-bouncing circuit, I couldn’t use the original rotary encoder library since that code uses a hardware interrupt a...

NES game pad

 This is re-post of a blog post I did about 15 years back, I don't know if I would use an Attiny microcontroller if I was to do this today. The price of chips with built in USB is now cost comparable, and hardware USB is more reliable. But it's a fun project and if you happen to have a microcontroller compatible with V-USB it's worth a try.   I was digging though some of my old junk and found a box of old Nintendo stuff and I thought that it might be cool to turn one of the controllers into a USB game pad. Now you can buy a USB NES style gamepad, but what's the fun in that. So, I started looking though my box of electronic parts and found a couple of Atmel Attiny 85 micro controllers. Sweet a chance to try out the AVR-USB library . Now you would think you need a clock crystal to sync the micro controller with the USB, but the AVR-USB library has an algorithm to calibrate the internal oscillator to within +/- 1% accuracy. Which is fortunate because if we had to use a cl...
