16. Old stuff, memories... Picture of the circuitry of my homebuilt FM Empfänger from the 80s. (Display etc not included). new 11.5.2019
15. Square to Sine with 8 Stage Shift Register - calculations: .jpg .xls CMOS Cookbook errata P383 (from me) (Replaces incorrect table in book) Don wrote 'Yes, there was an error that has not yet gotten fixed. Don't want to rush those things. 5.2022'. Comedian!... Book is now online here. 1.7.22
14. 'A Tuner' - a unit which producies accurate frequencies, used for tuning musical instruments.
Another old article of mine, published in the Electronic Organ Constructors Society Magazine of No.80 Apr.1978.
13. CIRCUITS: 18V Li-Accu Charger circuit (used at 0.5A) 6.1.23 toaster replacement circuit Alarm (Klingel) - eg. doorbell repeat in garden 1.7.22 microphone amplifier freezer warner water level / pump switch garden light replacement cct. 2 cells garden light replacement cct. single cellLow Voltage Monitor eg for NiMH accu 12.'18 (joining wires 7.'19 UTube)
12. AA Battery Tests: Lithium/Alkaline Lithium/Alkaline/NiMH, www.choice.com.au also tested the lithiums better than the rechargeables: "On average, the above NiMH models lasted about 2.5 times longer in our test cycle than all the non-rechargeables except the ENERGIZER e2 Lithium, which lasted about 50% longer than the best rechargeables." See also: http://dpfwiw.com/batteries.htm. The new low self discharge NiMHs are probably the best to use. 3.1.2007.
11. List of Audio Amplifier Articles, 1960 - 2006 Improved Dinsdale Amp original
10. Description of my 9 white LED head torch (for mountaineering)
9. Calculating total frequency deviation or jitter from the phase noise spectrum of a signal source - 4K zipped excel 5 file
8. Car electronic ignition circuit of mine, published in Wireless World, April 1975. If the points capacitor is left in the car (as in the circuit diagram), then a 82 ohm 2W resistor from the points input to the +12V line is necessary - to give this capacitor somewhere to discharge to. See also http://www.americanradiohistory.com/Archive-Wireless-World/70s/Wireless-World-1975-04.pdf - page 85
7. My filter (all even elements equal), published in the IEEE. IFF document finished
6. Colour Clock (new, 11/2012). Can only be read by 'electronic persons'. (See top of page).
Old clock: 7K stand alone exe file Click on any colour to exit. (written in Visual Basic 3 - works only on old windows (typical for windows))
5. Visual Basic Program for controlling a 3 line phase locked loop integrated circuit from the printer port. In this case the LMX2336. Simple program intended as a 'get you going in VB'. Knowledge of such ICs is necessary, as is a hour or two with VB. Visual Basic Version 3 was used, and as VB doesn't itself have any facility for controlling (!!!), a very useful free DLL from SoftCircuits Programming is used to accomplish this. The exe file is the stand alone control program and the other files are the visual basic code. (Thanks to Michael for some of the code) - 24K zip file
4. Calculating possible Mixer Products - 11K stand alone exe file
(written in Visual Basic 3. Therefore runs quite slowly.)
3. Planning Mixer Frequencies and Synthesizer Design - 9K zipped excel 5 file
2. Broadband Impedance Matching Circuit - 4 elements - 8K zipped excel 5 file
1. Conversion Program ____ VSWR, Reflection Coefficient etc. Also Polar Calculations. - 11K zipped excel 5 file
0. Math: decimal in binary electronic 20% values: addition of in parallel ratios of resonance
Making a protractor per hand Making a right angle Approximations to tan 30° primes 2
Best Sallen Key design program: Excel program (Excel, nicht Open Office benutzen) Description. Other articles: ti.com, ice77.net, okawa-denshi.jp, TI webbench design program
As my excel programs were written on a german excel they might possibly need altering to run on an english version.

Pro makers, students, and hobbyists can develop apps for Android mobile devices using the Basic For Android (B4A) programming language and Integrated Development Environment (B4A IDE). Dr. Dogan Ibrahim begins Android App Development for Electronics Designers with a description of how to install the B4A on a PC. He then presents simple projects to introduce B4A’s syntax and programming features. (from Elektor)
