Multifunctional DIY DC to DC Converter Auto Step - Up Step - Down Boost Buck Solar Power Supply ModuleThis is a buck–boost converter that has an output voltage magnitude that is either greater than or less than the input voltage magnitude.Comparing with...
In case we want to use more demanding Odroid-XU4's instead of Raspberry Pi3's, we have to improve power source leads to lower lose. Keep in mind that 5x Odroid's can pull > 100W under full load. As a part of my Ph.D research was to accelerate operations...
Step 2- Making the capacitor chargerCamera flash circuitry and capacitors can also be used for this project, but since a large number of them are required, I found it easier to buy some high voltage capacitors and make a dedicated charger for them ;...
Solder up them Address-Lines (And Clock)The core-concept behind sdramThing is that of loading (half of) the memory-locations with commands that will be (eventually) directly fed-back to the SDRAM itself. Taking into account the characteristics of SDRAM,...
This is a very simple module, it contains the two joystick ports and some logic. It depends on the sound module for the i/o. As per the earlier instruction step, the *R6* of Ed's sound module is required because earlier revisions can't be jumpered...
Attaching a SensorIn order to attach a sensor, motor, camera or other component to the Redtree Hydra, the FPGA inside must be programmed. We know that this is normally a tricky task, so we created a tool to simplify it. The Redtree Hydra has four I/O...
Why did I add a fan on the backside? The fan circulates air from the back to the front side which keeps PCB Cool from the Bottom side which is beneath the LEDs. This was a very crucial thing to do because as you already know, LEDs tend to heat up, and...
This diagram shows what could be one of the simplest state machines possible. It operates a hypothetical air machine at a gas station. You insert a quarter and the air compressor turns on for a fixed amount of time. When the timer runs out, the compressor...
Next we will prepare the water flow. I decided to use this combination of pump and tubing, because they fit without an adapter. Other combinations work also. Clear tubbing isnt the best solution, because algae will grow inside the tubes. you can prevent...
Green BMS hardware components are: Cell modules (the quantity is according to cells number) (*) n.1 Interface board(*) n.1 Arduino Mega board n.1 HC-05 Bluetooth module n.1 Transparent Plexiglass Control Unit case (laser cut dxf) Jst...
Ok I pored the cement in the tube with a blue foam board on the bottom glued to the sides. That seemed to work out well accept I stuck a blue foam board cutout with a hole cut out in it to keep the 2" pvc pipe in place. Bad Idea it moved the PVC pipe...
This instruction is for building the output inductor (two required - L401, L402). It describes materials and fabrication guidance but assumes the reader has experience assembling magnetics. Additional information can be found in the magnetics...
The functions for the servos will be very easy if you learned how to properly use them from step 3 so I will not spend much time on them. I will say however you will probably have to adjust the delay time and the angles they are turning. Do not...
