So i decided to build this Voltage Reference. I ordered a few LTC6655 from LInear Technology (http://cds.linear.com/docs/en/datasheet/6655fc.pdf). I made a small PCB for it Using the Parchment paper Methot. So these are the specs of it:
4.096V output voltage @2ppm
Max input voltage is 13.2 Volt
The PCB/ Module that i builded is 200mm By 150mm. So it’s definitely pocket size. ;D
Here are some Pictures.
In this Instructable user Dustin talks about how he uses Parchment Paper to make High quality PCB’s, So i tried it and it turned out to be pretty nice. This project is also featured on the MAKE: Blog.
Now i’m a MAKE: contributor. That means I now also talk about awesome/cool projects on the Make Blog.
Thank you for joining Camper Hangout’s 2013.
I hope you had a fun time at the Hangout’s.
I would like to thank all of you who joined the hangout’s.
But sadly enough ends Maker Camp this Friday.
But the camper hangout’s will continue until the 26th of August.
There will be a special hangout this Friday: http://goo.gl/QUJnCx
Have a nice day,
I toght it would be cool to add a more cumputery feeling to a Raspberry pi.
So i changed the status led’s:
PWR from dark red to bright white
ACT from dark green to bright Red
(See pictures below)
So this is a sort of repair.The original controller from the oven failed a while ago. So i decided to build one my self using a an Aruino. I ordered an extra ATmega 328P-PU (from Farnell) whit the Arduino boot loader on it.
I used this Intractable for code (click here for the intractable).
But i builded the hardware by myself.
So my part’s list:
1 ATmega 328P-PU whit bootloader
1 16 MHz cristal
2 22pf cap’s
2 0.01 uF cap’s
1 7805 voltage regulator
1 10K resistor
3 47K resistors
4 tactile switches
1 Lcd module (standard type)
1 transistor (BC547)
1 Relay (Rated for 30 Amp’s)
1 12 Volt Adaptor
Here are some images.
Please help me out.
Making cool projects asks for components.
And components are Expensive.
So if you could help me out by donating.
If you Donated, I will send you a personal “Thank You” message.
