Reflow oven controller got even better

If you are looking for professionally made surface mount PCBs, there is no doubt they are soldered in reflow oven. SMT components are too sensitive and small to be soldered by hand. This is why they are baked in ovens with controlled temperature profile. If you are going to build such oven, there is no problem with – you can get away dirty cheap. All you need is regular oven new or used and temperature controller. There is no big difference what type of oven you are going to use, the most important thing is that there were electric heating element. More important part is the controller. You can find many reflow oven controllers that can be successfully used. You can always build one, but why waste time on building… Continue reading

Fun FPV RC tank

If you have an Android phone you can download IP Webcam application and have remote IP camera where you can see video stream in web browser screen. But this stuff may become boring as you camera isn’t moving. Nikus decided to build a better solution that would allow follow things with FPV (First Person View). He took Arduino Leonardo and equipped it with robotic threaded platform. He used H-bridge TB6612FNG circuit to control motion motors. Also he added two servos for camera pan and tilt control. He built RF remote link by using two NRF24L01 modules. On his remote control he assembled two joysticks that are interfaced to another Arduino. After assemble was complete he had great robot that can move around the house and record videos. Since video is… Continue reading
