    Hi, I am looking for someone to design a t-shirt for me for our races this year. We are a motorcycle racing club in Co. Tipperary, we hold the Faugheen 50 Road Races in July each year. We have racers from all over Ireland, England, and a few from other European countries, and thousands of people come to spectate each year. Your design would be put on our T-shirts that will be sold in our shop, so we would be printing a lot. Attached is a pic of another road racing club t-shirt to give you an idea. We also need our sponsor's Mammon Competitions logo on these too. I have also attached other T-shirts we had throughout the years, to give you an idea, but we don't want racers on this year's ones and we also don't want the date on them so we can sell them again ...

    We are looking for an experienced Electrical Engineer with knowledge of food/automation equipment to help validate heater circuit conversion for the Australian market. We make food forming equipment for the US market. Our specifications use 240VAC, 3-phase, 60 Hz to power to energize a hydraulic ram (motor) and to supply single phase voltage directly to the heaters in our forming dies. We also transform the 240VAC to 120VAC for control circuitry. The available power in Australia is 415VAC, 3-phase, 50 Hz. We have swapped motor components to accommodate, and our controls transformer can convert this power to 120VAC. However, we need to validate our design ideas for our forming die heaters is appropriate, a special challenge given current supply constraints are limiting c...

When the switch is pressed and not released, the motor should make the travel forward 800 steps and reverse 800 steps and stop while touching the home switch. The circuit should wait until I press again the "run" button to go forward to close the gripper and reverse again to home switch. I need it to travel a specific distance.
