TwinTeeth: The PCB Mini-Factory

 TwinTeeth The PCB Mini-Factory

 

If you make your own PCBs this TwinTeeth machine might be just the thing you need for your bench.

 Thanks for the tip Charlie & Victor

“It includes the following functions:

  • UV Laser photoengraving on sensitive film or presensitized boards using an ultraviolet laser.
  • Drilling vias and holes using any mini-rotary tool like Dremel® or Proxxon®.
  • Dispensing solder paste with precision on SMD PCB pads.
  • Plotting circuits with a permanent pen-maker (if you prefer this method).
  • 3D printing knobs, casings, front-panels, even print circuits with conductive filament, or make circuits supports.
  • Milling/Carving soft materials or etching PCB copper with a v-bit (if you prefer this etching method).
  • And much more… because it is extendable and you can use any other tool you can fix on it.”

PCB Bad Solder Joint

bad solder joint

 

Product testing is very important, you can run a battery of electrical testing on your PCB but a visual inspection is also very important to spot failures that are waiting to happen in the future. Our friend Bob Davis has been busy repairing all sorts of random electronic items. The Bad solder joints seen above are from a Crown XTi 1000 power amplifier which is an amp that retails at over $1,000. You would think there would have been enough profit in there to allow for a quick visual inspection.

Sega Cartridges Resurrected using some old Computer Chips

Sega Cartridges Resurrected using some old Computer Chips

 

Dragao has a Sonic Cartridge that had some invalid instructions that would cause the game to crash at a certain point. The solution wasn’t to find a replacement game at the local flea market, he Resurrected the Sega Cartridges using some old Computer Chips. The game was originally loaded on 16 bit memory chips, not having any of these handy from the donor computer motherboards he piggy backed 2  8 bit memory chips to make it work. An Arduino was then used to blast the code onto the new chips.

DIY Water Level Sensor Build

DIY Water Level Sensor Build

 

Bob Johnson completed his DIY Water Level Sensor project. It can sense 4 levels of water, the results are transmitted using some Xbee devices. 

“The distance from my barn to the house is over 700ft. I used a 2.4Ghz yagi to send the signal to the house. This works great and no outside antenna is required at the receiving end. I have tried this setup at much smaller distances, and no yagi or directional antenna was required.

This setup has worked well for me. I use it to monitor my horses water trough. By eliminating the need for a micro-controller on the transmitting end and placing the Xbee in sleep mode, I have been able to run this setup for 10 months now on the same 3 AA batteries with the Xbee set in high power mode. “

Lost Signal RC Alarm & Lost Plane Finder

Lost Signal RC Alarm & Lost Plane Finder

 

When your RC plane flies  out of transmitter range some of them are setup to start a slow bank so that it hopefully flies closer to you and you can reacquire communication. What if that fails and the plane comes crashing back to earth? This Lost Signal RC Alarm & Lost Plane Finder project will help you in this case. When your transmitter is not connected the buzzer will sound so you can find it a bit easier. Construction is a nice and compact point to point solder construction which means no PCB is needed.

Valentines Day Slot Machine

Valentines Day Slot Machine 

 

If you want your valentine to work for their candy hearts why not build them a slot machine to let them win them. I have seen little bits before but this is the most complex device I have seen built!

“Try your luck with the littleBits Slot Machine and win a handful of candy hearts for your special someone. This slot machine operates just like the real thing. Pull the lever to start the graphics spinning on three DC motors. As they stop spinning in succession, win big when three hearts line up. When the hearts align, so do three bright LEDs and three corresponding light triggers. This signals the servo-activated trapdoor to release a candy jackpot.”

Completed Working Nokia 3310 Phone Multimeter Project_1

 

Remember the Nokia 3310 Phone Multimeter that we saw last month? Looks like there has been some massive work on the project. It is complete and looks like it works great. It’s fantastic to see a resistor plugged into the bottom of a phone!
