It's the end of summer and many students are coming out of a brief dip into the professional world  working alongside adults and performing entry level tasks, only to return back to classes in the fall. Some are paid, some are not  some provide both learning opportunities and a chance to build one's network, others less so. Across the board, most students will say that an internship is a better investment of time than sitting at home, or working a regular summer job.  But some students have found summer experiences that are, arguably, better for their careers — especially those students interested in entrepreneurship, not joining corporate life. I asked seven students who participated in Lightspeed Venture Partners' summer fellowship — a program that behaves like a startup accelerator without taking equity from the teams — how the experience compared to a summer internship, and what knowledge they'll be taking back to school. Would you consider a non-traditional summer ...

I've had a few requests for a quiz circuit, so here is a 4 input design which can easily be modified. Maybe, I should write the application notes in the style of a game show host ... New Quiz Circuit diagram Notes: This design uses four IC's and has four input circuits and four independent outputs and a single master reset switch. The outputs here are LED's but may be modified to drive lamps or buzzers. Only one output LED can be lit at any time. The first person to press their input switch, A,B,C,D will light the corresponding output LED, disabling the other inputs. The circuit uses all CMOS IC's part numbers shown on the diagram. The supply voltage may be anything between 3 and 15 volts. Alternatively, it may be built using equivalent TTL IC's and powered on 5 volts. The main component in this circuit is a bistable latch, here it is based on the dual 4013 D-type flip flop. Circuit Operation: Pressing the reset switch will clear all flip flops and extinguish any li...
