![]() I’ve labeled them to the best of my knowledge. Looking at the back of the board, there is not much there with the exception of the ICSP pads, which may be handy if you are inclined to try reprogramming the thing. In both cases additional signal diodes are added to intentionally raise activation voltage for the LED in series. To turn both on, a normal full swing pulse is needed, but for LED2 only mode the line gets driven high and then switched to input. LEDs for the second and third speed segments are driven similarly (Waveform 2). To drive green on, the output is driven high and then switched to an input (or Hi-Z state), so that lower voltage ends up somewhere between battery voltage and supply voltage. ![]() Since the same pin is also used as an ADC input, the battery voltage could be sampled at that stage. The most obvious optimization was done by grouping things together- lower LED is always on with the motor- might as well drive them at once. The red/green signal (Waveform 3) is more involved- to drive red the microcontroller switches to open drain mode and only pulls down, generating pulses between Vbat and 0 V. The razor uses 4 green and 1 red LEDs, but PIC10 here only has 3 pins available for all of them. submitted by Edgewell Personal Care - 3 years ago. The Schick Hydro SIlk 5 TrimStyle Razor requires one AAA battery. It gets a bit more interesting with the LED multiplexing. The Schick Hydro Silk 5 Trimstyle Razor requires 1 AAA battery. ![]() Speed is adjusted by varying duty cycle of the PWM signal (It goes in steps of 40%, 60% and 97%). The motor is powered directly from the battery voltage and is controlled via an NPN transistor. I also replaced the 2 very old NiCd cells with higher capacity RS cells I had spare, now it runs a lot longer between charges, though now I just have to charge it for 12 hours from empty, and the charge state indicator just blinks as it communicates with the charger for battery status.The design is somewhat predictable- we have a 3V boost power supply feeding the PIC microcontroller. My solution was to simply bypass the whole lot ( chip is unobtanium and the board is more than I would pay for the complete unit) and place a current limiting resistor and use a 12V wall wart as a charger. Not mentioned in the manual, but I looked up the chip as it died. Funny thing is the Phillips razor I have has a power supply that will charge the internal cells from an input voltage that starts at 12VDC and stops at 250VAC. The pack of 5 costs the same as a single unit of the "premium" one, and lasts just as long as well. Not surprising seeing as the blades are the same made on the same line, and the plastic mount is the same as the premium one just welded to the handle. Electric costs little to run, and the disposable gives me the same shave as the pack of expensive blades. That is why I have electric shavers and buy dispoable razors. Throughout this growth, we maintained a strong emphasis on fresh thinking which has resulted in groundbreaking products like Schick® Intuition®, Schick Hydro®, LED flashlights and lighting products, and new wireless battery chargers like the Qi-compliant Energizer® Inductive Charger. To further strengthen our shaving offerings, we brought in Edge® and Skintimate® brands in 2009 and American Safety Razor/Personna in 2011. In 2007 we acquired Playtex, bringing us leading brands in skin care, sun care, infant care and feminine care. Flip Trimmer: flip top back, precisely trim, flip back. The transformation began largely in 2003, with the purchase of our shaving and personal care brands Schick® and Wilkinson Sword®. 5 Ultra Glide Blades with Skin Guards that smooth your skin to reduce irritation. ![]() Schick Injector Blades - 7 ct (33) Schick Hydro 5 Sense Hydrate Razor Refills for Men, Pack of 12 (88) Schick Injector Blades - 7 Ct. But since going public in 2000, our continued commitment to innovation and acquisitions has allowed us to accelerate our growth even further across a broad portfolio of powerful household and personal care brands. Schick Hydro 5 razors for Men With 1 Razor Handle & 17 Razor Blades Refills.
