I have had a few schools and colleges students asking how to hear FUNcube thanks to your great ideal and development of the dongle. I can imagine Ron Broadbend looking down at you and patting you on the back saying well done. OK on the software, Real Ice has much potential and a good direction to take,I don’t like using hardware breaks so will stay away from pickit3 for now.Įveryone is following your development of the dongle with great excitement, been a long time in coming seeing this much excitement in the AMSAT world. I have just placed an advanced order for the Metis but now need to build my SMD back plate, now I know what you feel like working with ultra small SMD components, lol. HPSDR ARE USING THE Altera Cyclone III FPGA connected to a Gigabit Ethernet PHY and iTS working well at medium speeds, like you with the dongle this used default drivers too. Thanks for the reply and the additional information on the microcontrollers using ethernet, will have to be careful there. A stereoscopic microscope is essential! A comms test set, four channel scope, laptop, DVM, assorted aerosols, PSU, test radio, magnifying lamp, in circuit emulator, test jig and a selection of hand tools fill the rest of the table.
The mobile workshop consists of four soldering irons including tweezers and a hot air iron invaluable for rework. Hand soldering I can do anywhere, but reflow I can really only do in the static workshop. Recommended, I wouldn’t be without one now.
I was in total awe the first time I saw this.
If you’ve ever been to the electronics market in Hong Kong, you’ll have seen vendors at market stalls using these to re-chip mobile phones. I chose the latter, and it’s saved my bacon on a couple of occasions. Now I like Weller stuff as you can see in the photo below, but for a hot air gun either you can pay £700+ for the Weller or £65 for one on ebay from China. If you look closely, you’ll see the orientation of the middle chip on the bottom dongle is wrong compared to the others – I had to lift at re-orientate the device. The three QFNs were reflowed and I hand soldered the other parts: a long story as to why I didn’t reflow the lot, but basically it was down to the four dimensional logistics of where I was this weekend, and at what time I could do what! That 5p coin is about the same size as a US dime. The firmware is identical so it’s a bit of a head scratcher at this stage. Today I built three boards using parts from the production batch with the second, and hopefully final, spin.Īll worked first time, and sensitivity was as expected with the LNA now integrated, although I have noticed that this batch seem to hang after five or ten minutes of streaming, unlike the version first PCB spin, so I will be looking into that.
