Attiny 1634 interfering with nRF24L01+

-

i pleased myself when constructed combination of attiny1634 , nrf24l01+ this



until discovered not receive anything.

i built second 1 attiny attached in same way (with piece of double-sided sticky foam) wiring attiny quite separate nrf24 stuck to. let's attiny b stuck on nrf24 b - not connected electrically.

i have attiny1634 (let's call a) attached breadboard.

if connect nrf24 b  to attiny nrf24 works fine long attiny b unpowered. power attiny b communication stops.

some time ago built similar setup using dip atmega 328 , worked no problems.

my guess going on inside attiny emitting radio interference upsetting nrf24.

i wonder if has bright ideas how solve problem small size of attiny 1634 makes more attractive atmega 328

...r

what range of effect (move b away)?
perhaps grounded sheet of copper foil between boards eliminate interference.

my old soldering iron gave few days back. looking soldering station temperature controlled tip. came across site. has reviews these best soldering stations models . best? not sure. i heard weller wesd51 before. but, never heard hakko. yet, hakko fx888d has perfect 5 star rating amazon. plus, lot cheaper weller's. budget around $100. not know choose. wondering if of guys have used hakko fx888d before. how experience it? input helpful. thank you. been soldering 40+ years. been using hakko fx888d ~3 years, give 5 out of 5. http://www.tequipment.net/hakkofx888d-23by.html?gclid=cmvpoopevtecfqk5waodxyupyq i have 1 of these, works cheap. i hot air wand. https://www.amazon.ca/dp/b01gtyc61g/ref=pe_386430_126088100_te_item i highly recommend f888 .

Fuelino for Arduino Nano - motorcycle Fuel Injection control and data logger

i share project working in free time: name fuelino. fuelino fuel injection controller , data logger designed motorcycles equipped efi (electronic fuel injection). regulating fuel injected in cylinder, possible increase power of engine. if modification optional, if have stock engine, becomes mandatory if change components of motorcycle, such exhaust pipe, camshaft, cylinder size (bore kit), air filter , on. fuelino helps adjust injection timing, achieve proper stoichiometric air-fuel ratio maximizes output power of engine, or minimizes fuel consumption. compensation applied original signal timing, in %, depends on throttle position sensor signal (if connected), , engine rotation speed (calculated measured time period between 2 consecutive "start of injection" events). the project open source, can find more info @ following links: http://www.monocilindro.com/fuelino/ http://www.monocilindro.com/category/electronics/fuelino-project/ the following image shows how connec...
