mhacks refactor rev 1

Simple CMoy layout - a headphone amplifier. Plz note that connections to pin 5&6 are wrong, they have to be manually swapped (R3 to pin 5, R4 to pin6.)

Not tested or ordered yet!

Construction (building) of Chronopic 3 board

Main information is here: Chronopic 3.0 (Iearobotics) (in spanish).

MATERIALS LIST

Integrated circuits

Attention: Component VK200 it’s inespecific, eg. at Taiwan there’s lots of new vk200 models. We recommend VK2000 FB20010-3B-RC (Ferrite Bead Choke. 6-holes core wired 2.5 turns high current RF choke. Impedance 785Ohm at 100MHz and 460Ohm at 10MHz.)

If you cannot produce Chronopic 3, maybe you are interested in Chronopic 2. Here you have all information on Chronopic 2, also this forum post maybe useful: Juanfer explanation on Chronopic 2 (spanish).

Boscam RX5808 based 5.8GHz Diversity Receiver

v0.2: Pattern fixed, SMA can be soldered on same side.

Schematics and code by JReise http://jreise.de/2fachVideoDiversity/Daten/Schaltplan.jpg

Upgraded with auto scan an spectrum analyser using an Arduino Pro Mini with RX5808-pro Software https://code.google.com/p/rx5808-pro/wiki/Overview?tm=6
Note that you have to change one pin assignment in the code before compiling: #define rssiPinA from A6 to A5!

It is designed for the cheap ebay clone boards with this kind of pin-out (you can also use its tactile switch for S1)

This is hat-like board for the EasyRaceLapTimer system’s Raspberry Pi powered base station. This was designed to make cable setup easier, as well as provide an alternate means of powering the system, using a cheap regulator and hobby grade lipo/li-ion/SLA (2-3S) batteries. The board is sized for both the Raspberry Pi Model 2/3, for base station use, and Raspberry Pi Zero/A+/B+, for satellite station use (gate penalty enforcement - not tested).

Parts to complete base station:

• Raspberry Pi Model 2 or 3
• USB WiFi Adapter (not needed with Pi 3, but WILL have better range)
• 2.54mm 2x20 Pin Double Row Female Pin Header
• 5V regulator to power Raspberry Pi
  • Mini 360 DC Step Down Regulator (set to 5V BEFORE connecting to Pi)
  • Pololu 5V, 1A Step-Down Voltage Regulator D24V10F5 - also available here and here
  • A UBEC might also work, but be certain it outputs 5-5.1v, and can supply 2amps. Some UBECs output 5.5-6v which will destroy the Pi.
• 3x TSOP 31238 IR Receiver
• 2x MMBT2222A (T1, T2) <== Also used on Transponder SMD R1.4
• 2x 1kOhm 1206 Resistor (R2, R3)
• 100Ohm 1206 Resistor (R1) <== Also used on Transponder SMD R1.4
• 2x 10uF 1206 Capacitor (C1, C2) <== Also used on Transponder SMD R1.4
• 330-470uF Capacitor (C3)
• SMD Tact Switch 3x6x2.5mm <== Also used on Transponder SMD R1.4
• 5v Buzzer
• Wiring to connect IR receivers
  • 26 AWG servo wire for IR receivers
  • Crimpable servo connectors for IR receivers
• Power lead of choice
• Battery of choice (I use a 12v 8Ah sealed lead acid battery which also powers a speaker system, but a 2s lipo, li-ion, etc will work if you are just looking to power the Pi)

Optional:

• Case to house Pi and hat
  • 3D printable case - top and bottom
• 3D printable mounts for IR receivers
• 2.54mm single row male pin header (only 4-6 pins are needed)
  • Momentary Push Button Switch Panel Mount - Arcade Button, maybe
  • 12v External Buzzer
• Real-Time Clock to maintain time across boots (requires hand wiring and has NOT been tested)

Parts to create a bad ass sound system for playing the sound effects:

• .50 cal ammo can
• 20Wx2 stereo amplifier
  • 2.1mm by 5.5mm DC barrel connector - if you don’t want to cannibalize the power cord that comes with the amp.
• 4 inch speakers
• 3 foot 3.5mm male to male stereo cable
• 12V 8Ah sealed lead acid battery
• USB WiFi Adapter with External Antenna
  • 20cm RG316 RP-SMA Extension - for mounting antenna on top of ammo box
• Screws and nuts for mounting speakers and amp
• Velcro for mounting Raspberry Pi and battery
• Misc wiring

ERLT IR transponders for aircraft

Please check out R1.4fixes some difficult soldering issues - fixes some soldering issues with R1.3

This is a new updated version of the Alexander Bierbrauer’s IR transponder for multirotor (drone) racing with EasyRaceLapTimer system. This model has a button to allow changing the transponder code at the field. This minimizes transponder conflicts, especially when racing with other groups using the same ERLT system.

This board is intended to be powered by 5V from a spare servo connector on your receiver or flight controller. The hole in the board is for cable strain relief.

Note: ATTiny85 needs to be programmed with applicable code from EasyRaceLapTimer project. This board has not been tested.

Parts to populate each board:

• ATTiny85 SOP8
• MMBT2222A
• 33Ohm 1206 Resistor
• 330Ohm 1206 Resistor
• 1206 SMD LED
• 100Ohm 1206 Resistor
• SMD Tact Switch 3x6x2.5mm
• Infrared 950nm LED LD274-3
• 12mm Heat Shrink
• 26AWG Servo Lead

Optional (but recommended):

• 10uF 1206 Capacitor

Helpful:

• SOP-8 programming clip
