Solder Paste Dispenser

Solder Paste Dispenser


There are lots of expensive Solder Paste Dispenser options but there will come a time that you just need to do more than is practical to do with a syringe and your fingers. That is when building a quick and dirty machine would come in. Good thing there is a system that you can model your endeavors after. The tricorderproject.org has a nice and simple DIY Solder Paste Dispenser project that might be just what you are looking for.


“The prototype that I put together is more of a sketch in hardware to help me appreciate the issues of paste extrusion, and help hammer out a design. Instead of using a plunger, I’ve used a very long lead screw that acts as the plunger, and has a gear atop with a captive nut to transfer force. The gear is driven by a Parallax continuous rotation servo, which I thought I’d try given that it simplifies the design by having an integrated gear box (which gives it lots of torque), and it can be directly driven by a microcontroller rather than requiring a separate stepper driver.”

Arduino Quadcopter Project

at 2:42 pm. Filed under DIY Hacks


 Alvin Phyo built this quadcopter using Ardunio Nano and a GY-87 3-axis Gyro, this way he has total control of how the flight control works. There are lots of off the shelf control systems that would have been easier to get working but would not have the same ability to make it work exactly way Alvin would like.

Bug Zapper Illuminated Bike

 Bug Zapper Illuminated Bike


Steve from Rimstar.org has build an illumination system for his bike. Most of us would use a battery and a light right? Well Steve is using the bike power to generate thousands of volts and spark gap to warn people that a bike is coming. It has the added benefit of keeping people from wandering too close to the front of the bike!

“Want to make your bike create sparks as you drive?

One way I found is to add on a Wimshurst machine, an electrostatic machine that produces sparks. The cool thing is that the Wimshurst machine works by rotating two disks, normally using a hand crank… but connect it up to your bike pedals and now you rotate the disks as you pedal! To make it cooler, this one even uses a 3D printed sprocket!”

Capacitive Touch LED Table


This Capacitive Touch LED Table by uses an arduino to drive a neo pixel strip and uses the capacitive touch library to allow the aluminum trim to become a mode switch. The code is available to you can build your own if you like. She cut a hole in the top of an old table and mounted the electronics under glass. Looks great and the effects are nice.

Digital Display Updates the Look of Old Power Supply

 Digital Display Updates the Look of Old Power Supply


xrunner had an old Heath power supply. He changed out the original capacitors to some larger Nichicon units. That would be been enough but the addition of some inexpensive digital displays will make this unit look a bit more modern. Nice inexpensive upgrade but it will ensure this power supply will be usable for many years to come.

Vacuum System for Deposition

Vacuum System for Deposition_2 


Jerry Biehler is working on a Vacuum System for Deposition. It was removed from a university and needed quite a bit of work. Looks like there is still a lot of things to be done but it is sure a nice looking piece of equipment!

“So, some of the specs:

• 26″ Stainless bell jar, appears to be a Cha. The lower ring looks to have been added later and is held in place by clamps. The base has a rotary feedthrough for the shutter and a bunch of standard 1″ holes for other feedthroughs.
•​ Leybold XTC film thickness monitor and Airco crystal head
​• Lesker Ion Gauge Controller
​• Varian Extrion thermocouple gauge and system control panel
​• Varian 6″ Diffusion Pump
​• Leybold Ruvac WA-150 Roots Blower
​• Leybold D30AC Roughing pump
​• Water cooled evaporation transformer and control, control is homemade and transformer appears to be a varian.”

Dead Macbook Pro Logic Board Diagnosis

at 7:06 pm. Filed under DIY Hacks


Louis Rossmann shows us how he troubleshoots a Dead Macbook Pro Logic Board. He goes deep into the diagnosis using his microscope and a nice big monitor to nicely view the schematic. You can tell that he has been through this circuit many times since it seems to be a familiar as the back of his hand. 

“Here I diagnose a board that has issues on PP3V42_G3H which caused issues with the MCP, whose clock circuit is powered by PP3V42_G3H! I go through my diagnostic process and mindset, and follow from beginning to end as I resolve the problem.”
