The requirementMany ICs are now only available in SMT (Surface Mount Technology) footprints for example the Microchip ATTiny 0, 1 and 2 series. This makes prototyping difficult when using these components. The marketThere are many SMT to DIL adapters out there but at hefty prices per adapter. So I rolled my own. The solutionI chose SOT-23, SOIC8 and SOIC16 footprints because these cover the majority of requirements - for me anyway since I have yet to use an LFCSP device, although that will soon happen. I considered QFP and QFN also but there are so many pin count options that I decided to do those as a separate panel. FeaturesIncluded with the SOIC8 and 16 footprints on this panel are also TSSOP and MSOP packages on the same adapter as the SOIC package, and SOT23-6 can be used for SOT23-3 and SOT23-5 packages making this a very versatile board. There are 36xSOT23-6 plus 20xSOIC8 plus 8xSOIC16 (also works for SOIC14) adapters on a panel of 100x95mm.There are v-grooves for separating the adapters into strips but be aware that there is a need to cut the final adapters apart. Using a thinner 1mm pcb helps make this an easy task. I will add some pics to this narrative soon.

Details: https://openhardwarecoza.wordpress.com/2020/03/05/diy-18650-powerwall-with-onboard-bms/This is based off the 18650 Powerwall projectIncludes onboard BMS circuitry to protect and balance charge the cells. Modules are stackable with 25mm brass M3 Hex spacers, to build packs up to 100aH Balance connectors provided if you want to you can skip adding the Balance charger circuitry and instead use your own like Batrium, Orion, etcOnboard cell protectionUndervolt disconnect (2.9v per cell)Overvolt disconnectOvercurrent Disconnect

### DESCRIPTIONArduino shields are boards that can be plugged on top of the Arduino PCB to extend its capabilities. This makes prototyping with Arduino plug and play. Instead of soldering or wiring external devices or sensors, you can simply hook your board with a shield. This speeds up development time even for absolute beginners.Student Companion Easy Relay 1 Shield is a simple Arduino shield with 1 relay that can be used to control high voltage/current devices from your arduino.### TECHNICAL DETAILS / COMPONENTS### LEARN / TOPIC / BUILD INSTRUCTIONSBuild Instructions

### DESCRIPTIONThis automatic temperature control system has the ability to monitor and control the temperature of a specified space without human intervention. This project uses a PIC microcontroller to automatically control the temperature of an area. This area could be a small plant, a house or any place or device that require a controlled temperature like an incubator (egg) for example. The desired temperature setting is entered using a keypad. The temperature of the area is measured using an analog temperature sensor.The microcontroller reads the temperature continuously and compares it with the desired value. If the desired value is higher than the measured value, then the heater is turned ON to heat the area. If on the other hand the measured value is higher than the desired value, then the fan is switched ON to cool off the area until the required temperature is reached. If the temperature reaches a certain critical value 40?C or higher, the buzzer will sound continuously and an LED will blink until the temperature deceases below 40?C.An LCD display shows the measured temperature continuously.### TECHNICAL DETAILS / COMPONENTS### LEARN / TOPIC / BUILD INSTRUCTIONSTo learn more about this project and downlaod source code, please visit:Website: https://www.studentcompanion.co.za/automatic-temperature-control-using-pic-microcontroller-mikroc/ Video: https://youtu.be/s6GXfBZRoRM

### DESCRIPTIONThis is a very simple breadboard power supply Breakout Board that takes power from a DC wall Socket and outputs a selectable 5V or 3.3V regulated voltage using a switch. This board can be easily inserted into a breadboard using a .1" headers mounted on the bottom of the PCB. Pins labeled VCC and GND plug directly into the power lines. ### TECHNICAL DETAILS / COMPONENTSDC Barrel Connector (2.1mm center positive)TO-220 Voltage Regulator (LM317 1.5A max current)1N4001 Reverse Protection Diode100uF 25V Capacitor10uF 25V Capacitor0.1uF 50V CapacitorRed Power LED - High Brightness2 x SPDT Slide Switch4 x 0.1" Header Pins2 x 330 Resistor 1/6W390 Resistor 1/6W240 Resistor 1/6WPTC resettable fuse### LEARN / TOPIC / BUILD INSTRUCTIONShttps://www.studentcompanion.co.za/breadboard-regulated-power-supply-5v-3-3v/

This is a project to display and save your location during activities. There are a lot of fancy GPS watches that can do it all , but for those who want to experiment and be creative , this is the way to go.The main parts are Atmel Mega 128 cpu - Gps unit , 1.3" Oled , uSD card , 4 buttons for user interface , usb charge , usb serial interface for bootload , pads for first ISP pgm , temperature sensor , ext gps ant socket , vibrator motor , buzzer .This board is ver 2 for a 1.3 " Oled display , the 0.96 " is just too small for active outside use. The firmawre is all in BASCOM AVR and I have used ver 1 now for about 2 years and tracked a lot of races with it. Pcb and compoment is quite tight and need a sober stable hand for soldering!GPS data is saved as a GPX file and can then be uploaded to STRAVA for diplay etc.
