15 OF THE MOST DISGUSTING THINGS IN YOUR HOME THAT YOU NEED TO CLEAN A.S.A.P

Hello friends Today I am back with another project called DIY AUTOMATIC SOLAR CHARGE CONTROLLER. It’s an automatic switching circuit that used to control the charging of a battery from solar panels or any other source. It’s a 555 based simple circuits the charge the battery when the battery charge goes below the lower limits, and stop charging when the battery reaches it's upper limit voltage

Early concept for a fully symmetric belt-driven extruder carriage for upgrading Prusa Mendel. Belt-driven means there's no stepper motor on the X-carriage, so it can be much lighter and move much faster. It has two X-belts that are controlled by one stepper on each side. If both belts move in the same direction, the X-carriage moves in that direction too. If both belts move in opposite directions, the extruder moves but the X-carriage stands still. x_motion = (stepper1 + stepper2) &#...
