- MacroFab and Mouser Electronics have teamed up to create a free monthly meetup in Houston (April 26th) for anyone involved with hardware & electronics engineering or manufacturing. Hosted on the last Wednesday of every month, these meetups are designed to build a community of professionals who want to learn from one another, gain new insights on emerging electronics technologies, and expand their network.
- Sign up here!

- Parker has been working on the next step of the RPI3 LVDS project.
- Pinout the SODIMM connector for the RPI3 Compute Module. See Figure 1.
- Part number 1473149-4 by TE Connectivity
- LVDS DS90C365A IC is net listed up
- Trying to use the PWM function to control the backlight of the LCD.
- GPIO40 is PWM0 on the RPI3
- Still to be done
- Power 1.8V, 3.3V, 12V
- SD card
- HDMI
- USB and a USB Hub
- Break out all the pins
- Test points for clk signals and data streams
- Stephen has a challenge for the listeners.
- Goal: Design for a ring of LEDs that surround a control knob on a synthesizer and light up according to the position of the knob
- Requirements
- The circuit must connect to a potentiometer (this can be a dual gang version) example: rv16a01f
- The ring of LEDs must be centered on a 12mm radius around the potentiometer.
- Whole circuit must not be larger 1.2” W x 1.2”H x 1.2”D
- PCB can solder directly to pins on potentiometer
- Multiple PCBs is acceptable if needed
- Color of the LEDs does not matter although green or red is preferable
- Number of LEDs is 16 minimum and 32 maximum
- LEDs are arranged on a 300 degree arc (potentiometer has 300 degrees of rotation) starting at 240 degrees and ending at -60 degrees
- The circuit will receive external 5V power so it must have through hole pads for power and gnd
- CHEAP CHEAP CHEAP! Do this for as cheap as possible
- Rapid Fire Opinion (RFOs)
- Revealing Capcom’s Custom Silicon Security – Hackaday
- Capcom developed their arcade boards to die with their secrets through a “suicide” system. System name CPS2
- Basically all the game code was encrypted and the key was stored in volatile ram kept alive by a battery.
- Reminds Parker of the reflow oven that MacroFab currently use.
- NXP chip checks your booze – Electronics Weekly
- The Tag uses NXP’s NTAG 213 Tag Tamper technology which checks the origin of the bottle, detects if the bottle has been opened, and creates an URL for the bottle.
- Stick it on, and if someone tries to remove it, the NFC chip will separate from the tag, rendering it unusable.
- Example Tag that uses the NTAG213
- Datasheet
- IoT Startup Bricks Customers Garage Door Intentionally – Hack A Day
- Garadget remotely bricked an unhappy customer’s WiFi garage door for giving a bad Amazon review and being rude to company reps.
- “Technically there is no bricking, though,” the rep replied. “No changes are made to the hardware or the firmware of the device, just denied use of company servers.”
- What happens when this fine firm to go bankrupt? Do all their openers stop working?
